However, speech samples used in stuttering measurement research have varied in duration. This study was undertaken to examine whether the duration of speech samples influences the reliability of measurement of severity of stuttering by SLPs. Methods: Ten specialist SLPs rated 27 audio, English speech samples of three different durations (9 × 1-minute, 9 × 3-minutes, 9 × 5-minutes) of adults who stutter, using a 9-point severity rating (SR) scale. Results: The speech sample durations produced similar results when using the SR scale to measure severity of stuttering. Thus, samples of 1, 3 and 5-minute durations were found to be equally appropriate for reliability research and training purposes. Variability was found to be larger in the moderate severity range than the mild and severe ranges. Conclusions: Data trends suggest that SLPs and researchers should focus more attention on practice and training in the middle ranges of the SR scale, due to increased variability in this range.

Currently, best practice for treating stuttering in young children is considered to be implementation of the Lidcombe Program. The Lidcombe Program is a behaviourally based treatment approach which involves parents delivering feedback to their child¿s stuttered and stutter-free speech in structured and unstructured conversations, in a natural environment. Currently, there is no published research documenting implementation of the Lidcombe Program in mainland China. Given the cultural differences that exist between Australia (where the treatment was developed) and China, an investigation into the feasibility of the treatment into this cross-cultural context is warranted. Methods: This study investigates implementation of the Lidcombe Program to two Mandarin-speaking children using a descriptive single case study design. The primary outcome, percent syllables stuttered (%SS), was measured within¿¿ and beyond-clinic at two assessment points, and analysed for statistically significant change. Results: Both participants in the study achieved a significant reduction in stuttering rates, suggesting the Lidcombe Program may be a viable option to treat some children in a Mandarin-speaking population in China. Additionally, the treating therapists provided feedback on cultural considerations when implanting the program to this population. Conclusion: There is a need for research into effective and evidence-based stuttering treatments for Mandarin-speaking children in mainland China. This study is a preliminary investigation into the effectiveness of the Lidcombe Program in this context.

© 2017 Royal College of Speech and Language Therapists Background: Clinical placements are crucial to the development of skills and competencies in speech¿language pathology (SLP) education and, more generally, a requirement of all health professional training programmes. Literature from medical education provides a context for understanding how the environment can be vital to all students¿ learning. Given the increasing costs of education and demands on health services, students who struggle or fail on clinical placement place an additional burden on educators. Therefore, if more is known or understood about these students and their experience in relation to the clinical learning environment, appropriate strategies and support can be provided to reduce the burden. However, this literature does not specifically explore marginal or failing students and their experience. Aims: To review existing research that has explored failing and struggling health professional students undertaking clinical placements and, in particular, SLP students. Methods & Procedures: A critical narrative review was undertaken. Three electronic databases, ProQuest, CINAHL and OVID (Medline 1948¿), were searched for papers exploring marginal and failing students in clinical placement contexts across all health professions, published between 1988 and 2017. Data were extracted and examined to determine the breadth of the existing research, and publications were critically appraised and major research themes identified. Main Contribution: Sixty-nine papers were included in the review. The majority came from medicine and nursing in the United States and United Kingdom, with other allied health disciplines less well represented. The review identified key themes with the majority of papers focused on identification of at risk students and support and remediation. The review also highlighted the absence of literature relating to the student voice and in the allied health professions. Conclusions & Implications: This review highlighted the limited research related to failing/struggling student learning in clinical contexts, and only a handful of papers have specifically addressed marginal or failing students in allied health professions. The complexity of interrelated factors in this field has been highlighted in this review. Further research needs to include the student's voice to develop greater understanding and insights of struggle and failure in clinical contexts.

No research to date has examined Vietnamese speech therapists¿ reliability when measuring severity of stuttering in their native language (Vietnamese) and other languages (e.g. English, a common second language). Twenty-five Vietnamese speech therapists rated 20 speech samples (10 Vietnamese, 10 English) of adults who stutter using a 9-point severity rating (SR) scale on two occasions. Approximately half of the judges were able to measure severity of stuttering reliably in Vietnamese. Judges¿ performance in English was poorer than in their native language. Irrespective of language, judges showed greater variability of their use of the scale in the moderate range. Results highlight the need for judges to develop intra- and interjudge agreement when using the scale to measure stuttering in their native and other languages. Research into the development and evaluation of practice and/or training packages would be beneficial to this population, in all languages, with a focus in the moderate range of the scale.

Purpose: Case-study methodology studying change is often used in the field of speech-language pathology, but it can be criticized for not being statistically robust. Yet with the heterogeneous nature of many communication disorders, case studies allow clinicians and researchers to closely observe and report on change. Such information is valuable and can further inform large-scale experimental designs. In this research note, a statistical analysis for case-study data is outlined that employs a modification to the Reliable Change Index (Jacobson & Truax, 1991). The relationship between reliable change and clinical significance is discussed. Example data are used to guide the reader through the use and application of this analysis. Method: A method of analysis is detailed that is suitable for assessing change in measures with binary categorical outcomes. The analysis is illustrated using data from one individual, measured before and after treatment for stuttering. Conclusions: The application of this approach to assess change in categorical, binary data has potential application in speech-language pathology. It enables clinicians and researchers to analyze results from case studies for their statistical and clinical significance. This new method addresses a gap in the research design literature, that is, the lack of analysis methods for noncontinuous data (such as counts, rates, proportions of events) that may be used in case-study designs.

Speech sound disorders reportedly co-occur in young children who stutter at a substantial rate. Despite this, there is a paucity of scientific research available to support a treatment approach when these disorders co-exist. Similarly, little is known about how clinicians are currently working with this caseload given that best practice for the treatment of both disorders in isolation has evolved in recent years. This study used a qualitative approach to explore current clinical management and rationales when working with children who have co-occurring stuttering and speech sound disorder. Thirteen participant SLPs engaged in semi-structured telephone interviews. Interview data were analysed based on principles derived from grounded theory. Several themes were identified including multi-faceted assessment, workplace challenges, weighing-up the evidence, and direct intervention. The core theme, clinical reasoning, highlighted the participants' main concern, that not enough is known about this caseload on which to base decisions about intervention. There was consensus that little is available in the research literature to guide decisions relating to service delivery. These findings highlight the need for further research to provide evidence-based guidelines for clinical practice with this caseload. © 2013 The Speech Pathology Association of Australia Limited.
