In acquired brain injury (ABI), social cognition is a contributing factor to the changes observed in functional outcomes. However, progress in assessing and understanding social cognitive impairments is limited by a lack of consistency in terminology and the proliferation in assessment tools, leading to a lack of consensus on what should be assessed and how. This review aims to examine the domains of social cognition commonly assessed in ABI, the assessment tools used, and the appropriateness of these tools for researchers and clinicians. Using the Arksey and O¿Malley scoping review methodology, 367 articles reporting results from 10,930 people with an ABI met our inclusion criteria. The five most commonly assessed domains of social cognition were emotion perception, theory of mind, social communication, identity recognition and empathy. The most commonly used measure of these domains included: the Ekman and Friesen photo series, Faux Pas Recognition Test, La Trobe Communication Questionnaire, Benton Facial Recognition Test and the Interpersonal Reactivity Index. There are well-validated measures readily available that are underused in favour of non-standardized measures clinically or the development of one¿s own measure in research. The appropriateness of the identified measure for research and clinical use was discussed, including suggestions for future research.

Chromosome 22q11.2 deletion syndrome (22q11DS) is characterised by a complex behavioural phenotype including anxiety, attention-deficit/hyperactivity disorder and psychosis. In the current study, we aimed at improving our understanding of the heterogeneity of behavioural characteristics in a group of 129 young people (aged 4¿22) with a confirmed 22q11.2 microdeletion and 116 age and gender matched typically developing controls. Half the participants with 22q11DS had behaviour characterised by emotion dysregulation. A cluster analyses, of the participants with 22q11DS, revealed four groups characterised by intact emotion regulation; predominantly internalizing problems; both internalizing and externalizing problems; and predominantly externalizing difficulties. Importantly, it was found that young people with 22q11DS¿whose emotion dysregulation was characterised by externalizing problems had the poorest levels of functioning. As our understanding of 22q11DS improves, it is becoming increasingly clear that we need a better understanding of how individual differences and psychosocial factors contribute to, and interact with one another, to result in the observable individual differences in the 22q11DS behavioural phenotype.

Objective: Maternal asthma often complicates pregnancy and is linked with poorer quality of life. Additionally, individuals with asthma are at an increased risk of depression and anxiety. We examined whether asthma during pregnancy is related to parenting stress in the first year postpartum and if this relationship varies with level of asthma control. Methods: This cohort survey-based study included mothers with (n = 157) and without (n = 79) asthma. Mothers with asthma participated in this study following participation in a randomized controlled trial of a novel asthma management strategy during pregnancy. Mothers completed the Parenting Stress Index¿Short Form during the first 12 months postpartum. Mothers with asthma also completed the Asthma Control Questionnaire. Results: Parenting stress did not differ between mothers with and without asthma. Additionally, for mothers with asthma, there were no differences in levels of parenting stress based on asthma control. Conclusions: This study suggests that mothers with asthma are not at an increased risk for excessive parenting stress. However, due to response and sampling bias, levels of parenting stress in asthmatic mothers may be underreported in our sample.

Infants diagnosed with autism spectrum disorder (autism) have difficulty engaging in social communication and interactions with others and often experience language impairment. The use of infant-directed speech (IDS), which is the speech register used when interacting with infants, is associated with infant language and socio-communicative development. The aim of this study was twofold; the first aim was to scope the literature to determine if evidence exists for differences between the IDS caregivers use to infants at high-risk or those later diagnosed with autism, and the IDS typically spoken to neurotypical infants. The second aim was to investigate if any IDS characteristics used by caregivers of high-risk or diagnosed infant populations predicted language development. Twenty-six studies were included and provided evidence that high-risk and later diagnosed infants are exposed to similar amounts of IDS as their neurotypical peers. There is evidence, however, that the IDS used with high-risk and later diagnosed infants may comprise shorter utterances, more action-directing content, fewer questions, more attention bids, and more follow-in commenting. There is also evidence that more attention bids and follow-in commenting used to infants at high risk or those later diagnosed with autism were associated with better language abilities longitudinally.

The Enhancing NeuroImaging Genetics through Meta-Analysis copy number variant (ENIGMA-CNV) and 22q11.2 Deletion Syndrome Working Groups (22q-ENIGMA WGs) were created to gain insight into the involvement of genetic factors in human brain development and related cognitive, psychiatric and behavioral manifestations. To that end, the ENIGMA-CNV WG has collated CNV and magnetic resonance imaging (MRI) data from ~49,000 individuals across 38 global research sites, yielding one of the largest studies to date on the effects of CNVs on brain structures in the general population. The 22q-ENIGMA WG includes 12 international research centers that assessed over 533 individuals with a confirmed 22q11.2 deletion syndrome, 40 with 22q11.2 duplications, and 333 typically developing controls, creating the largest-ever 22q11.2 CNV neuroimaging data set. In this review, we outline the ENIGMA infrastructure and procedures for multi-site analysis of CNVs and MRI data. So far, ENIGMA has identified effects of the 22q11.2, 16p11.2 distal, 15q11.2, and 1q21.1 distal CNVs on subcortical and cortical brain structures. Each CNV is associated with differences in cognitive, neurodevelopmental and neuropsychiatric traits, with characteristic patterns of brain structural abnormalities. Evidence of gene-dosage effects on distinct brain regions also emerged, providing further insight into genotype¿phenotype relationships. Taken together, these results offer a more comprehensive picture of molecular mechanisms involved in typical and atypical brain development. This ¿genotype-first¿ approach also contributes to our understanding of the etiopathogenesis of brain disorders. Finally, we outline future directions to better understand effects of CNVs on brain structure and behavior.

Background:: In Australia, using non-invasive prenatal testing (NIPT) to screen for fetal abnormalities is becoming more commonplace. However, there is a lack of standardised procedures surrounding pre-test counselling. This holds the potential for variability in pregnant people¿s experiences when undergoing NIPT, which subsequently may impact their ability to make informed decisions surrounding NIPT results. Aim:: This study sought to characterise the experiences of Australian women undergoing NIPT, including perceptions of informed choice, counselling experiences and decision to undergo NIPT. Materials and Methods:: Australian women who had been recently pregnant (n¿=¿94) completed an online survey which assessed: their knowledge of and attitude toward NIPT; satisfaction with counselling; satisfaction with their decision; and decisional conflict to undergo NIPT. The survey also allowed participants to provide qualitative information about their counselling experience and reasons for undergoing NIPT. Results:: Overall, participants had good knowledge of and positive attitudes toward NIPT, experienced low decisional conflict and were overall satisfied with their counselling experience and decision to undergo NIPT. However, some participants expressed dissatisfaction with the lack of information provided, and biased language, by counselling providers. The desire to be informed was the most frequent reason for undergoing NIPT. Conclusion:: The provision of accurate and objective information in pre-test counselling is important to reduce decisional conflict and improve satisfaction with the decision to undergo NIPT. It is recommended counselling providers present pregnant people with neutral, objective, and accurate information at the time of pre-test counselling.

22q11.2 deletion syndrome (22q11DS) is a neurodevelopmental disorder caused by a microdeletion on the long arm of chromosome 22. Sleep problems have been reported in this population, and psychiatric disorders and affect dysregulation are common to the behavioral phenotype of 22q11DS. Sleep and affect have been consistently linked across multiple studies, yet despite this very little research has investigated sleep problems in 22q11DS, or the link between sleep and affect in this population. The Experience Sampling Method was used to track daily reports of sleep quality and affect in a total of 29 individuals with 22q11DS and 21 control subjects. Measurements were recorded during a 6-day period using an electronic device that prompted daily response with audio cues. Participants with 22q11DS were found to experience a longer sleep onset latency and a greater amount, and duration, of night wakings compared with control subjects. Despite this, no significant between-group difference was found for subjective sleep quality. 22q11DS participants reported more experiences of negative affect and less positive affect than control subjects. A bidirectional relationship was found between sleep measures and affect. Sleep problems can cause a wide range of negative health effects, and individuals with 22q11DS are particularly vulnerable to deficits of sleep. To ensure high standards of care, healthcare providers should be aware of the possibility and impact of sleep problems in this population.

Objectives: Differences in the development of autistic children have been observed within the first year of life. Infant siblings of autistic children who are later diagnosed with autism themselves have differences in temperament, social communication, attention, and sensory and motor behaviors by 12¿months of age. However, less is known about the early development of other increased-likelihood groups. Some studies have identified that children born to mothers with asthma have a slightly elevated likelihood of autism. However, no studies have examined other aspects of their early development. Methods: Using a case series design, we profiled the temperament (Carey Temperament Scales), sensory (Sensory Profile 2), and global developmental features (Bayley-III) of seven Australian infants born to mothers with asthma who were screened to have an elevated likelihood of autism (First Year Inventory). Results: We found differences from the norms in temperament across the three timepoints (6¿weeks, 6¿months, and 12¿months), in the domains of rhythmicity, mood, persistence, and distractibility. Infants had typical sensory features at 6¿weeks and 6¿months; however, a sensory-sensitivity subtype was observed at 12¿months. Lastly, at 12¿months, cognitive skills were mostly typical, language skills were underdeveloped, and motor skills varied between infants. Conclusions: Results suggest that there may be a developmental profile indicative of an elevated likelihood of autism in infants born to mothers with asthma. However, due to the small sample size, these findings need to be considered with caution. Further research is needed to confirm diagnoses of autism in our sample.

Maternal asthma in pregnancy is associated with an increased risk of adverse perinatal outcomes. Adverse perinatal outcomes may result in poorer infant developmental outcomes, such as temperament and sensory difficulties. This study aimed to (1) assess differences in temperament and sensory features between infants born to mothers with and without asthma and (2) investigate differences in these infant behaviours as a function of maternal asthma severity and asthma control. Mothers completed the Carey Temperament Scales and the Sensory Profile 2 at either 6 weeks, 6 months, or 12 months postpartum. Overall, we observed no significant differences between infants born to mothers with and without asthma in their temperament or sensory features; scores in both domains fell within the normative range. More infants in the asthma group, however, were reported to be highly distractible. When compared with normative data, infants in both groups were reported to have poor predictability of biological functions and fewer infants engaged in low levels of sensory behaviours. Some infants were observed to experience difficulties with hyper-reactivity within several domains. Maternal asthma severity and control during pregnancy were not linked to significant differences between infant temperament and sensory features. The present findings indicate that infants born to mothers with asthma are not at an increased risk overall for temperament or sensory difficulties, compared to control infants. However, a subset of infants across both groups may be at risk for attention or sensory hyper-reactivity difficulties. Further research into the developmental outcomes of infants born to mothers with asthma is warranted.

The 22q11.2 deletion syndrome (22q11.2DS) results from non-allelic homologous recombination between low-copy repeats termed LCR22. About 60%¿70% of individuals with the typical 3 megabase (Mb) deletion from LCR22A-D have congenital heart disease, mostly of the conotruncal type (CTD), whereas others have normal cardiac anatomy. In this study, we tested whether variants in the hemizygous LCR22A-D region are associated with risk for CTDs on the basis of the sequence of the 22q11.2 region from 1,053 22q11.2DS individuals. We found a significant association (FDR p < 0.05) of the CTD subset with 62 common variants in a single linkage disequilibrium (LD) block in a 350 kb interval harboring CRKL. A total of 45 of the 62 variants were associated with increased risk for CTDs (odds ratio [OR) ranges: 1.64¿4.75). Associations of four variants were replicated in a meta-analysis of three genome-wide association studies of CTDs in affected individuals without 22q11.2DS. One of the replicated variants, rs178252, is located in an open chromatin region and resides in the double-elite enhancer, GH22J020947, that is predicted to regulate CRKL (CRK-like proto-oncogene, cytoplasmic adaptor) expression. Approximately 23% of patients with nested LCR22C-D deletions have CTDs, and inactivation of Crkl in mice causes CTDs, thus implicating this gene as a modifier. Rs178252 and rs6004160 are expression quantitative trait loci (eQTLs) of CRKL. Furthermore, set-based tests identified an enhancer that is predicted to target CRKL and is significantly associated with CTD risk (GH22J020946, sequence kernal association test (SKAT) p = 7.21 × 10-5) in the 22q11.2DS cohort. These findings suggest that variance in CTD penetrance in the 22q11.2DS population can be explained in part by variants affecting CRKL expression.

Background: 22q11.2 deletion syndrome (22q11DS) is the most common microdeletion syndrome. Parents of emerging adults with 22q11DS have an intense and ongoing involvement in their child's life. This study explores the lived experience of parents in relation to their child becoming independent and establishing intimate relationships. Method: Interpretative phenomenological analysis was used to explore the positive and negative experiences of five parents of emerging adults with 22q11DS. Results: Supervised independence overarched four subordinate themes. These themes highlighted the difficulties experienced by parents attempting to relinquish control whilst still experiencing a need to keep their child safe as their child negotiated a complex stage of life. Parents waited for ¿signs¿ from their child before initiating conversations about intimate relationships. Conclusions: These findings provide insight into the lived experience of parenting a child through the transition into adulthood, providing a catalyst for further research with the aim of facilitating better services for families.

Purpose of Brief Review: 22q11.2 deletion syndrome (22q11.2DS) is a micro-deletion disorder with a heterogenous complex presentation including significant communication difficulties. This brief review discusses the communication profile and potential approaches to enhancing communication skills for these learners. Recent Findings: The communication profile of 22q11.2DS has been described in several studies identifying early assessment, monitoring, and on-going language interventions as best practice for those with 22q11.2DS. However, few studies have reported on empirical findings of specific interventions to enhance the communicative skills of learners with 22q11.2DS. Summary: The distinct communication profile of individuals with 22q11.2DS offers researchers and practitioners an opportunity to develop tailored interventions to support effective communication skills for learners with 22q11.2DS. This review recommends that, in addition to existing interventions, augmentative and alternative communication (AAC) should be evaluated to (a) support early expressive communication for children and (b) support socio-communication strategies for older learners with 22q11.2DS.

The 22q11.2 deletion (22q11DS) is a common chromosomal microdeletion and a potent risk factor for psychotic illness. Prior studies reported widespread cortical changes in 22q11DS, but were generally underpowered to characterize neuroanatomic abnormalities associated with psychosis in 22q11DS, and/or neuroanatomic effects of variability in deletion size. To address these issues, we developed the ENIGMA (Enhancing Neuro Imaging Genetics Through Meta-Analysis) 22q11.2 Working Group, representing the largest analysis of brain structural alterations in 22q11DS to date. The imaging data were collected from 10 centers worldwide, including 474 subjects with 22q11DS (age = 18.2 ± 8.6; 46.9% female) and 315 typically developing, matched controls (age = 18.0 ± 9.2; 45.9% female). Compared to controls, 22q11DS individuals showed thicker cortical gray matter overall (left/right hemispheres: Cohen¿s d = 0.61/0.65), but focal thickness reduction in temporal and cingulate cortex. Cortical surface area (SA), however, showed pervasive reductions in 22q11DS (left/right hemispheres: d = -1.01/-1.02). 22q11DS cases vs. controls were classified with 93.8% accuracy based on these neuroanatomic patterns. Comparison of 22q11DS-psychosis to idiopathic schizophrenia (ENIGMA-Schizophrenia Working Group) revealed significant convergence of affected brain regions, particularly in fronto-temporal cortex. Finally, cortical SA was significantly greater in 22q11DS cases with smaller 1.5 Mb deletions, relative to those with typical 3 Mb deletions. We found a robust neuroanatomic signature of 22q11DS, and the first evidence that deletion size impacts brain structure. Psychotic illness in this highly penetrant deletion was associated with similar neuroanatomic abnormalities to idiopathic schizophrenia. These consistent cross-site findings highlight the homogeneity of this single genetic etiology, and support the suitability of 22q11DS as a biological model of schizophrenia.

Objective: We aimed to examine the prevalence and severity of psychological distress of women with asthma in both the prenatal and postnatal periods, and to determine whether asthmatic women with and without mental health problems differ in self-management, medications knowledge, and asthma symptoms. Methods: We assessed spirometry performance and asthma symptoms in 120 women (mean age 29.8 years) before 23 weeks gestation, as part of the Breathing for Life Trial (Trial ID: ACTRN12613000202763). Prenatal depression data was obtained from medical records. At 6 weeks postpartum, we assessed general health, self-reported asthma control, depression symptoms (with the Edinburgh Postnatal Depression Scale) and adaptive functioning (with the Achenbach System of Empirically Based Assessment scales). Results: Twenty percent of our sample reported having a current mental health diagnosis, 14% reported currently receiving mental health care, while 47% reported having received mental health care in the past (and may/may not have received a diagnosis). The sample scored high on the Aggressive Behavior, Avoidant Personality, and Attention Deficit/Hyperactivity scales. Poorer self-reported postnatal asthma control was strongly correlated with elevated somatic complaints, externalizing problems, antisocial personality problems, and greater withdrawal. Prenatal spirometry or asthma severity and control were largely not associated with measures of psychopathology. Conclusions: These findings indicate that pregnant women with asthma frequently report issues with psychopathology during the prenatal and postnatal periods, and that the subjective perception of asthma control may be more related to psychopathology than objective asthma measures. However, due to sample bias, these findings are likely to be understated.

22q11.2 deletion syndrome (22q11DS)¿a neurodevelopmental condition caused by a hemizygous deletion on chromosome 22¿is associated with an elevated risk of psychosis and other developmental brain disorders. Prior single-site diffusion magnetic resonance imaging (dMRI) studies have reported altered white matter (WM) microstructure in 22q11DS, but small samples and variable methods have led to contradictory results. Here we present the largest study ever conducted of dMRI-derived measures of WM microstructure in 22q11DS (334 22q11.2 deletion carriers and 260 healthy age- and sex-matched controls; age range 6¿52 years). Using harmonization protocols developed by the ENIGMA-DTI working group, we identified widespread reductions in mean, axial and radial diffusivities in 22q11DS, most pronounced in regions with major cortico-cortical and cortico-thalamic fibers: the corona radiata, corpus callosum, superior longitudinal fasciculus, posterior thalamic radiations, and sagittal stratum (Cohen¿s d¿s ranging from -0.9 to -1.3). Only the posterior limb of the internal capsule (IC), comprised primarily of corticofugal fibers, showed higher axial diffusivity in 22q11DS. 22q11DS patients showed higher mean fractional anisotropy (FA) in callosal and projection fibers (IC and corona radiata) relative to controls, but lower FA than controls in regions with predominantly association fibers. Psychotic illness in 22q11DS was associated with more substantial diffusivity reductions in multiple regions. Overall, these findings indicate large effects of the 22q11.2 deletion on WM microstructure, especially in major cortico-cortical connections. Taken together with findings from animal models, this pattern of abnormalities may reflect disrupted neurogenesis of projection neurons in outer cortical layers.

The 22q11.2 deletion syndrome (22q11DS) is associated with a 20¿25% risk of schizophrenia. In a cohort of 962 individuals with 22q11DS, we examined the shared genetic basis between schizophrenia and schizophrenia-related early trajectory phenotypes: sub-threshold symptoms of psychosis, low baseline intellectual functioning and cognitive decline. We studied the association of these phenotypes with two polygenic scores, derived for schizophrenia and intelligence, and evaluated their use for individual risk prediction in 22q11DS. Polygenic scores were not only associated with schizophrenia and baseline intelligence quotient (IQ), respectively, but schizophrenia polygenic score was also significantly associated with cognitive (verbal IQ) decline and nominally associated with sub-threshold psychosis. Furthermore, in comparing the tail-end deciles of the schizophrenia and IQ polygenic score distributions, 33% versus 9% of individuals with 22q11DS had schizophrenia, and 63% versus 24% of individuals had intellectual disability. Collectively, these data show a shared genetic basis for schizophrenia and schizophrenia-related phenotypes and also highlight the future potential of polygenic scores for risk stratification among individuals with highly, but incompletely, penetrant genetic variants.

Objective: This paper will describe the development of a programme of SMS messages including parenting information and support to be sent to the mobile phones of mothers with severe mental illness (SMI) and their partners from early pregnancy to 24 weeks post birth. Method: Text messages (total 176) designed and tested for fathers (SMS4Dads) addressing father-infant attachment, co-parenting and self-care (including Mood Tracker texts asking fathers to rate their mood) were adapted by an expert advisory group of clinicians with experience across perinatal mental health services. Messages were rated on importance, clarity, acceptability (separately for mothers and fathers) and being consistent with current evidence. Additional messages were developed specifically for this population and all messages were tested for literacy level. The SMS4dads ¿Mood Tracker¿ was redesigned to address common stress-inducing parenting issues such as infant crying, lack of sleep, and self-doubt about capacity to parent with an escalation process in cases of significant distress. Results: Separate protocol tested text-message banks for mothers (141 messages), and fathers (141 messages) were developed. Fourteen Mood Tracker topics were developed with two levels of distress escalation linked to local mental health services. Discussion: The need for accurate descriptions of health interventions processes is widely recognised, particularly in the case of digital mental health. This study provides a detailed description of the adaptive design by clinicians and researchers of brief text messages suitable for mothers with severe mental illness and their partners.

Objective: Maternal asthma during pregnancy is associated with a higher risk of negative perinatal outcomes. However, little is known about the direct effects of maternal asthma on infant cognitive development. We examined the evidence for an impact of maternal asthma during pregnancy on cognitive and behavioral development of the child. Data sources: We conducted a MEDLINE, PsychINFO, and manual search of the databases for all available studies until January 9th, 2018. Study Selections: Studies were deemed relevant if they included child cognitive and behavioral development as the outcome, with maternal asthma as the determinant of interest. Results: Ten articles matched selection criteria. Some studies report that maternal asthma is associated with increased risk for autism and intellectual disability in children. However, these effects are small and are often eliminated when controlling for confounding variables. Other studies have found no association. The only prospective study found that well-managed asthma during pregnancy was not associated with negative developmental outcomes in children. Conclusions: The evidence suggests that the relationship between maternal asthma during pregnancy and poor developmental and behavioral outcomes of children is weak. Children of mothers with well-managed asthma during pregnancy have similar developmental trajectories to those born to healthy mothers. Prospective, longitudinal studies are needed to confirm these conclusions. Optimal asthma management is important in pregnancy as it may have longer term benefits for the health of the offspring. As the rate of asthma increases in the population, the implications of maternal asthma on child development will be of greater importance.

The 22q11.2 deletion syndrome is caused by non-allelic homologous recombination events during meiosis between low copy repeats (LCR22) termed A, B, C, and D. Most patients have a typical LCR22A-D (AD) deletion of 3 million base pairs (Mb). In this report, we evaluated IQ scores in 1,478 subjects with 22q11.2DS. The mean of full scale IQ, verbal IQ, and performance IQ scores in our cohort were 72.41 (standard deviation-SD of 13.72), 75.91(SD of 14.46), and 73.01(SD of 13.71), respectively. To investigate whether IQ scores are associated with deletion size, we examined individuals with the 3 Mb, AD (n = 1,353) and nested 1.5 Mb, AB (n = 74) deletions, since they comprised the largest subgroups. We found that full scale IQ was decreased by 6.25 points (p =.002), verbal IQ was decreased by 8.17 points (p =.0002) and performance IQ was decreased by 4.03 points (p =.028) in subjects with the AD versus AB deletion. Thus, individuals with the smaller, 1.5 Mb AB deletion have modestly higher IQ scores than those with the larger, 3 Mb AD deletion. Overall, the deletion of genes in the AB region largely explains the observed low IQ in the 22q11.2DS population. However, our results also indicate that haploinsufficiency of genes in the LCR22B-D region (BD) exert an additional negative impact on IQ. Furthermore, we did not find evidence of a confounding effect of severe congenital heart disease on IQ scores in our cohort.

Background: The transition to adulthood is a major developmental milestone; a time of self-discovery and increased independence. For young adults (YA) with intellectual disabilities (ID), however, this period is especially challenging. The increased incidence of mental health disorders in this population, such as depression and anxiety, make this transition even more difficult, increasing caregiver burden at a time when the young adult would traditionally be gaining independence. It is not clear, however, why YA with ID are more susceptible and what factors may predict mental health symptoms. Method: Potential risk and protective factors (demographic variables, coping styles, sense of hopelessness, unmet achievement of adulthood milestones, self-reflection and insight) of anxiety and depression symptoms were assessed in 55 YA with ID and a sample of age-matched controls. Results: Insight was the strongest predictor of anxiety (with gender in the controls) for YA with and without ID, with increased insight predicting fewer anxiety symptoms. However, YA with ID had significantly less insight than their aged-matched counterparts and significantly higher levels of anxiety. They were also less likely to have achieved traditional adulthood milestones. Maladaptive coping was the strongest predictor of depression for YA with ID. In comparison, both maladaptive coping and insight predicted depression in controls. More maladaptive coping predicted increased depressive symptoms in both populations, whilst increased insight predicted fewer depressive symptoms in controls. Conclusions: Insight and maladaptive coping are potential targets in the treatment of anxiety and depression among YA with ID. Longitudinal intervention studies exploring the efficacy of such targeted programmes in reducing mental health symptoms and improving the transition to adulthood for these young people are recommended.

This analysis aimed to examine the association of social dysfunction with food security status, fruit intake, vegetable intake, meal frequency and breakfast consumption in people with psychosis from the Hunter New England (HNE) catchment site of the Survey of High Impact Psychosis (SHIP). Social dysfunction and dietary information were collected using standardised tools. Independent binary logistic regressions were used to examine the association between social dysfunction and food security status, fruit intake, vegetable intake, meal frequency and breakfast consumption. Although social dysfunction did not have a statistically significant association with most diet variables, participants with obvious to severe social dysfunction were 0.872 (95% CI (0.778, 0.976)) less likely to eat breakfast than those with no social dysfunction p < 0.05. Participants with social dysfunction were therefore, 13% less likely to have breakfast. This paper highlights high rates of social dysfunction, significant food insecurity, and intakes of fruits and vegetables below recommendations in people with psychosis. In light of this, a greater focus needs to be given to dietary behaviours and social dysfunction in lifestyle interventions delivered to people with psychosis. Well-designed observational research is also needed to further examine the relationship between social dysfunction and dietary behaviour in people with psychosis.

Background: 22q11.2 deletion syndrome (22q11.2DS) is the most common microdeletion syndrome. However, there is little research examining the effect of this multisystem disorder on the family, particularly siblings. The current study was a phenomenological exploration of sense-making in siblings of a person with 22q11.2DS. Method: Interpretative phenomenological analysis informed a detailed and open examination of being a sibling of a person with 22q11.2DS. Using in-depth semistructured interviews, five typically developing siblings (two men, three women) of people with 22q11.2DS were individually interviewed, providing the data set for transcription and thematic analysis. Results: The theme ¿They are the priority¿ overarched two subordinate themes that emerged from participants' descriptions of the struggle with acceptance and finding positive meaning. Participants oscillated between conflicting feelings about their sibling with 22q11.2DS always taking centre stage. For example, they felt anger, guilt and resentment; yet, they also embraced patience, empathy and gratitude. Conclusions: This phenomenological study provides a foundation for future research relating to 22q11.2DS and fostering family wellbeing, particularly around acceptance and psychological growth. The siblings in this study actively withdrew from their family to allow prioritisation of their affected sibling. However, this does not mean that their needs should be overlooked. There are easily accessible resources to support siblings of individuals with disabilities, and it is important for health professionals and parents to consider these options.

The presentation of 22q11.2 deletion syndrome (22q11DS) is symptomatically variable, presenting diagnostic challenges for paediatricians and anxious uncertainty in parents. The ¿lived¿ experience of parenting a small child diagnosed with 22q11DS is unknown particularly how parents make sense, both positive and negative, of their role. A phenomenological study sought subjective interpretations from two fathers and four mothers of a young child (8¿36¿months) diagnosed with 22q11DS. Using interpretative phenomenological analysis, data were collected through semi-structured interviews and thematically analysed. Four themes embodied uncertainty and fear simultaneously experienced by these parents such as anticipatory traumatic distress, systemic stigma, confusion at professional smoke screens and ¿not knowing¿. This cacophony of distressing emotions plagued their unanswered fear, guilt, loss and grief. In seeking hope, their parenting journey was able to be redefined as one of intrapersonal and interpersonal growth from the adversity of 22q11DS. This study provides a lens into the experiences of parents struggling to make sense of their journey with 22q11DS in the early parenting years. It highlights the complex distress of parenting a small child whose development is fraught with uncertainly and where stigma and suspicion are often experienced when seeking support from social and health systems. However, a metamorphosis of personal strengths also emerged facilitated by hope. Healthcare professionals can best assist through open discussion that acknowledges often limited knowledge, using the guidelines for management of 22q11DS in guiding parents.

We aimed to examine and compare sex-differences in people receiving treatment for psychotic illnesses in community settings, based on long or short duration of illness; expecting association between longer illness-duration and worse outcomes in women and men. Clinical, demographic and service-use data from the Survey of High Impact Psychosis were analysed by sex and duration of illness (=5 years; =6 years), using independent t-tests, chi-square tests, one-way ANOVA, and Cramer's V. Of the 1825 participants, 47% had schizophrenia, 17.5% bipolar and 16.1% schizo-affective disorders. More women than men had undertaken post-school education, maintained relationships, and been living in their own homes. Women with a shorter-illness-duration showed social functioning equivalent to non-ill women in the general population. Men tended to have an early illness onset, show premorbid dysfunction, be single, show severe disability, and to use illicit substances. Men with a longer-illness-duration were very socially disadvantaged and isolated, often experiencing homelessness and substance use. Men with a short-illness-duration were most likely to be in paid employment, but two-thirds earned less than $AUD500 per fortnight. Men with longer-illness-duration showed most disability, socially and globally. Interventions should be guided by diagnosis, but also by a person's sex and duration of illness.

Background This phenomenological study explores the perceptions, hopes, and dreams of relationships and parenting of women with a genetic intellectual disability. Method Five women with both 22q11.2 deletion syndrome (22q11DS) and intellectual disability took part in semistructured interviews. Their subjective interpretations were analysed using interpretative phenomenological analysis. Results Four main themes emerged: (a) challenges and acceptance of having 22q11DS, (b) desire for social acceptance and normality, (c) welcoming of emotional and practical support, and (d) individuation. The themes describe the discordance between the challenges and acceptance of having a genetic disorder, the need to be ¿normal,¿ the importance and appreciation of social support, and the women¿s aspirations for independence. Conclusions Young women with 22q11DS approach their adulthood with a sense of optimism and personal competence yet recognise their unique challenges. Parental support is valued despite the need for independence. The findings provide insight into the lived experience of women with 22q11DS.

The unique demands of the foster carer role are associated with high levels of self-reported stress among foster carers. The current study examines the amount of carer stress that can be attributed to certain role specific challenges and how stress from these challenges varies between carers and placements. As a secondary aim the study examines carer perceptions on current organisational support and training. Participants were sourced from a national fostering agency with branches in the local area. Carers were eligible to participate in the study if they were caring full time for at least one foster child. Eligible carers completed an identical online or paper survey including measures of general stress and parenting stress as well as study specific measures regarding satisfaction with organisational training and support. Results demonstrated that challenging behaviours are the most stressful unique role demand for foster carers and the largest predictor of carer stress levels. Overwhelmingly carers reported a desire for additional training in order to support them in their role. The results support previous research outlining the difficulties faced by foster carers and the need to improve support and training to ensure good placement outcomes including placement stability and reduced carer attrition.

Objectives: 22q11.2 deletion syndrome (22q11DS), a complex genetic syndrome associated with more than 180 features, presents complex challenges for parents including gaining a diagnosis. This phenomenological study sought the "lived" interpretations of parents supporting an adult child with 22q11DS, a poorly researched area. Method: Interpretative phenomenological analysis informed a detailed and open exploration of parenting a child through to adult life with 22q11DS. Using in-depth semistructured interviews, 8 parents (2 male, 6 female) of adult children with 22q11DS were individually interviewed; providing the data set for transcription and thematic analysis. Results: Losing "I" Finding "self," overarched 6 subordinate themes that emerged from participants' articulated descriptions of psychological distress and psychological growth. Distress in parenting a child with 22q11DS was experienced through stigma, loss, grief, and guilt. Progressively, stigma undermined independence, friendships, and instinctual judgement. Ill-informed hierarchical structures experienced as layers of obstruction and lack of awareness of the syndrome triggered angry advocacy for their child. Diagnosis brought opposing relief and grief. In time, they came to value their unique "accomplishments," collected on their journey with 22q11DS, and in turn, consciously valued authentic "self" expressed through empathy, humility, gratitude, and pride. Conclusion: Parental distress through societal, educational, and health care invalidation persisted for decades for all participants. Conversely, distress facilitated psychological growth for redefining "self" and role as parents over time. Building on this phenomenological cameo, future research can educate against the plight of 22q11DS families. It can enlighten health care professionals in buffering against associated stigma, blame, and self-doubt, and in fostering psychological well-being.

Background: Social difficulties are often noted among people with intellectual disabilities. Children and adults with 22q.11.2 deletion syndrome (22q11DS) often have poorer social competence as well as poorer performance on measures of executive and social-cognitive skills compared with typically developing young people. However, the relationship between social functioning and more basic processes of social cognition and executive functioning are not well understood in 22q11DS. The present study examined the relationship between social-cognitive measures of emotion attribution and theory of mind with executive functioning and their contribution to social competence in 22q11DS. Method: The present cross-sectional study measured social cognition and executive performance of 24 adolescents with 22q11DS compared with 27 age-matched typically developing controls. Social cognition was tested using the emotion attribution task (EAT) and a picture sequencing task (PST), which tested mentalising (false-belief), sequencing, cause and effect, and inhibition. Executive functioning was assessed using computerised versions of the Tower of London task and working memory measures of spatial and non-spatial ability. Social competence was also assessed using the parent-reported Strengths and Difficulties Questionnaire. Results: Adolescents with 22q11DS showed impaired false-belief, emotion attribution and executive functioning compared with typically developing control participants. Poorer performance was reported on all story types in the PST, although, patterns of errors and response times across story types were similar in both groups. General sequencing ability was the strongest predictor of false-belief, and performance on the false-belief task predicted emotion attribution accuracy. Intellectual functioning, rather than theory of mind or executive functioning, predicted social competence in 22q11DS. Conclusions: Performance on social-cognitive tasks of theory of mind indicate evidence of a general underlying dysfunction in 22q11DS that includes executive ability to understand cause and effect, to logically reason about social scenarios and also to inhibit responses to salient, but misleading cues. However, general intellectual ability is closely related to actual social competence suggesting that a generalised intellectual deficit coupled with more specific executive impairments may best explain poor social cognition in 22q11DS.

Research demonstrates that people living with serious mental illness (SMI) contend with widespread public stigma; however, little is known about the specific experiences of stigma that mothers, and in particular fathers, with SMI encounter as parents. This study aimed to explore and compare the experiences of stigma for mothers and fathers with SMI inferred not only by living with a mental illness but also potential compounding gender effects, and the associated impact of stigma on parenting. Telephone surveys were conducted with 93 participants with SMI who previously identified as parents in the Second Australian National Survey of Psychosis. Results indicated that mothers were more likely than fathers to perceive and internalise stigma associated with their mental illness. Conversely, fathers were more inclined to perceive stigma relating to their gender and to hold stigmatising attitudes towards others. Mental illness and gender stigma predicted poorer self-reported parenting experiences for both mothers and fathers. These findings may assist in tailoring interventions for mothers and fathers with SMI.

Background: Research suggests children with genetic disorders exhibit greater coping skills when they are aware of their condition and its heritability. While the experiences parents have at diagnosis may influence their decision to disclose the diagnosis to their children, there is little research into this communication. The aim of the current study was to examine the relationship between the diagnosis experience and the disclosure experience for parents of children with developmental disorders of a known genetic aetiology: parents of children with 22q11.2 deletion syndrome (22q11DS) were compared with a group of parents with children affected with other genetic diagnoses, with a similar age of diagnosis (e.g. fragile X syndrome) and a group where diagnosis generally occurs early (i.e. Down syndrome). Method: The sample comprised 559 parents and caregivers of children with genetic developmental disorders, and an online survey was utilised. Items from the questionnaire were combined to create variables for diagnosis experience, parental disclosure experience, child's disclosure experience, and parental coping and self-efficacy. Results: Across all groups parents reported that the diagnosis experience was negative and often accompanied by a lack of support and appropriate information. Sixty-eight per cent of those in the 22q11DS and 58.3% in the Similar Conditions groups had disclosed the diagnosis to their child, whereas only 32.7% of the Down syndrome group had. Eighty-six per cent of the Down syndrome group felt they had sufficient information to talk to their child compared with 44.1% of the Similar Conditions group and 32.6% of the 22q11DS group. Parents reported disclosing the diagnosis to their child because they did not want to create secrets; and that they considered the child's age when disclosing. In the 22q11DS and Similar Conditions groups, a poor diagnosis experience was significantly associated with negative parental disclosure experiences. In the Similar Conditions group, a poor diagnosis experience was also significantly associated with a more negative child disclosure experience. Conclusions: As expected this study highlights how difficult most parents find the diagnosis experience. Importantly, the data indicate that the personal experiences the parents have can have a long-term impact on how well they cope with telling their child about the diagnosis. It is important for clinicians to consider the long-term ramifications of the diagnosis experience and give the parents opportunities; through, for instance, psychoeducation to prepare for telling their child about the diagnosis. Further research is warranted to explore what type of information would be useful for parents to receive.

Importance: Patients with 22q11.2 deletion syndrome (22q11DS) have an elevated (25%) risk of developing schizophrenia. Recent reports have suggested that a subgroup of children with 22q11DS display a substantial decline in cognitive abilities starting at a young age.Objective: To determine whether early cognitive decline is associated with risk of psychotic disorder in 22q11DS.Design, Setting, And Participants: Prospective longitudinal cohort study. As part of an international research consortium initiative, we used the largest data set of intelligence (IQ) measurements in patients with 22q11DS reported to date to investigate longitudinal IQ trajectories and the risk of subsequent psychotic illness. A total of 829 patients with a confirmed hemizygous 22q11.2 deletion, recruited through 12 international clinical research sites, were included. Both psychiatric assessments and longitudinal IQ measurements were available for a subset of 411 patients (388 with=1 assessment at age 8-24 years).Main Outcomes And Measures: Diagnosis of a psychotic disorder, initial IQ, longitudinal IQ trajectory, and timing of the last psychiatric assessment with respect to the last IQ test.Results: Among 411 patients with 22q11DS, 55 (13.4%) were diagnosed as having a psychotic disorder. The mean (SD) age at the most recent psychiatric assessment was 16.1 (6.2) years. The mean (SD) full-scale IQ at first cognitive assessment was lower in patients who developed a psychotic disorder (65.5 [12.0]) compared with those without a psychotic disorder (74.0 [14.0]). On average, children with 22q11DS showed a mild decline in IQ (full-scale IQ, 7.04 points) with increasing age, particularly in the domain of verbal IQ (9.02 points). In those who developed psychotic illness, this decline was significantly steeper (P < .001). Those with a negative deviation from the average cognitive trajectory observed in 22q11DS were at significantly increased risk for the development of a psychotic disorder (odds ratio = 2.49; 95%CI, 1.24-5.00; P = .01). The divergence of verbal IQ trajectories between those who subsequently developed a psychotic disorder and those who did not was distinguishable from age 11 years onward.Conclusions And Relevance: In 22q11DS, early cognitive decline is a robust indicator of the risk of developing a psychotic illness. These findings mirror those observed in idiopathic schizophrenia. The results provide further support for investigations of 22q11DS as a genetic model for elucidating neurobiological mechanisms underlying the development of psychosis.

Background: 22q11.2 deletion syndrome (22q11DS) is associated with a number of physical anomalies and neuropsychological deficits including impairments in executive and sensorimotor function. It is estimated that 25% of children with 22q11DS will develop schizophrenia and other psychotic disorders later in life. Evidence of genetic transmission of information processing deficits in schizophrenia suggests performance in 22q11DS individuals will enhance understanding of the neurobiological and genetic substrates associated with information processing. In this report, we examine information processing in 22q11DS using measures of startle eyeblink modification and antisaccade inhibition to explore similarities with schizophrenia and associations with neurocognitive performance. Methods: Startle modification (passive and active tasks; 120- and 480-ms pre-pulse intervals) and antisaccade inhibition were measured in 25 individuals with genetically confirmed 22q11DS and 30 healthy control subjects. Results: Individuals with 22q1 1DS exhibited increased antisaccade error as well as some evidence (trend-level effect) of impaired sensorimotor gating during the active condition, suggesting a dysfunction in controlled attentional processing, rather than a pre-attentive dysfunction using this paradigm. Conclusions: The findings from the present study show similarities with previous studies in clinical populations associated with 22q11DS such as schizophrenia that may indicate shared dysfunction of inhibition pathways in these groups.

Dense surface models can be used to analyze 3D facial morphology by establishing a correspondence of thousands of points across each 3D face image. The models provide dramatic visualizations of 3D face-shape variation with potential for training physicians to recognize the key components of particular syndromes. We demonstrate their use to visualize and recognize shape differences in a collection of 3D face images that includes 280 controls (2 weeks to 56 years of age), 90 individuals with Noonan syndrome (NS) (7 months to 56 years), and 60 individuals with velo-cardio-facial syndrome (VCFS; 3 to 17 years of age). Ten-fold cross-validation testing of discrimination between the three groups was carried out on unseen test examples using five pattern recognition algorithms (nearest mean, C5.0 decision trees, neural networks, logistic regression, and support vector machines). For discriminating between individuals with NS and controls, the best average sensitivity and specificity levels were 92 and 93% for children, 83 and 94% for adults, and 88 and 94% for the children and adults combined. For individuals with VCFS and controls, the best results were 83 and 92%. In a comparison of individuals with NS and individuals with VCFS, a correct identification rate of 95% was achieved for both syndromes. © 2004 Wiley-Liss, Inc.
