The Classroom Communication Resource (CCR) intervention to change peer's attitudes towards children who stutter (CWS): study protocol for a randomised controlled trial

Communicative practices and perceptions towards stuttering people in South Africa

BACKGROUND

 A few studies have explored the life experiences of people who stutter. Research has shown that stuttering affects a significant number of people in the population.

OBJECTIVES

 The study was designed to explore the experiences of people who stutter and the perception of stuttering in South Africa.

METHOD

 Four people who identified as South Africans who stutter participated in this study. The primary investigator conducted semi-structured interviews with each of the participants. In addition, a questionnaire was administered to 20 acquaintances of all the participants. Transcriptions of interviews and results of questionnaires were analysed for major and minor themes.

RESULTS

 Results of this study suggest different perceptions by those who stutter and those acquainted with them. The findings of the study show that people who stutter experience communication barriers, so they adopt certain strategies to manage and cope with their speech disorder. The findings showed that stuttering has a pervasive impact on the lives of people who stutter and how they view themselves, considering negative societal views.

CONCLUSION

 Evaluation of the results from the study reveals that although stuttering is a common speech disorder, many people who are less informed about it harbour various stereotypes and myths that stigmatise stuttering. This study concludes by outlining recommendations for creating awareness of stuttering. It suggests vigorous campaigns aiming at promoting a multilevel approach that extends beyond the mere social and professional understanding of stuttering but addresses the inherent perceptions, myths, and stereotypes around stuttering.Contribution: Experiences of people who stutter and perceptions towards stuttering can help to better understand the speech disorder and overcome myths and stereotyping of stuttering.

Street-connected children with communication disabilities and their caregivers in Western Kenya: experiences, beliefs and needs

PURPOSE

Although street-connected children with communication disability have been identified in Western Kenya, little is currently known about the impact of communication disability on this group. In order to inform future service development, this qualitative study sought to understand the experiences, views and needs of street-connected children with communication disability, and of their caregivers at home and at school.

MATERIALS AND METHODS

13 children, 12 caregivers and 12 school-based Learning Support Assistants participated in interactive sessions, semi-structured interviews and focus groups respectively. Interviews were translated, transcribed and analysed thematically, using framework analysis.

RESULTS

Six main themes, with sub-themes, were identified: understanding and awareness of communication disability; the role of others; needs of the children and what might help; impact on those supporting the children; caregiver and Learning Support Assistant needs: support to better help the child; thoughts about the future. Participants' responses highlighted the importance of improving others' attitudes, awareness and willingness to adapt their communication, as well as a need for trusted relationships and some specialist help.

CONCLUSION

Organisations working with street-connected children should take communication disability into account in their services and interventions. Input based on a social model of disability is likely to be acceptable.Implications for rehabilitationThe attitudes and behaviour of others affect how communication disability is experienced by street-connected children and their families.Intervention based on a social model of disability and aimed at improving the communication environment around the child is likely to be acceptable to children, caregivers and education support workers.Caregivers and education support workers want more training and support alongside specialist intervention.Communication at the level of the child is central to building trusted relationships, which are important to the success of street-connected children's rehabilitation and re-integration.

Sensitivity of methods for analyzing continuous outcome from stratified cluster randomized trials - an empirical comparison study

The assessment of the sensitivity of statistical methods has received little attention in cluster randomized trials (CRTs), especially for stratified CRT when the outcome of interest is continuous. We empirically examined the sensitivity of five methods for analyzing the continuous outcome from a stratified CRT - aimed to investigate the efficacy of the Classroom Communication Resource (CCR) compared to usual care to improve the peer attitude towards children who stutter among grade 7 students. Schools – the clusters, were divided into quintile based on their socio-political resources, and then stratified by quintile. The schools were then randomized to CCR and usual care groups in each stratum. The primary outcome was Stuttering Resource Outcomes Measure. Five methods, including the primary method, were used in this study to examine the effect of CCR. The individual-level methods were: (i) linear regression; (ii) mixed-effects method; (iii) GEE with exchangeable correlation structure (primary method of analysis). And the cluster-level methods were: (iv) cluster-level linear regression; and (v) meta-regression. These methods were also compared with or without adjustment for stratification. Ten schools were stratified by quintile, and then randomized to CCR (223 students) and usual care (231 students) groups. The direction of the estimated differences was same for all the methods except meta-regression. The widths of the 95% confidence intervals were narrower when adjusted for stratification. The overall conclusion from all the methods was similar but slightly differed in terms of effect estimate and widths of confidence intervals.

The Satisfaction with Communication in Everyday Speaking Situations (SCESS) scale: An overarching outcome measure of treatment effect

PURPOSE

The Consolidated Standards of Reporting Trials (CONSORT) statement strongly suggests one primary outcome for clinical trials, yet the outcomes of stuttering treatments span numerous behavioral and psychosocial domains. That presents a roadblock to eventual meta-analysis of clinical trials for adults who stutter.

METHOD

We propose a simple and convenient outcome measure for clinical trials of stuttering treatment for adults that spans whatever behavioral and psychosocial factors might impel clients to seek treatment: a nine-point scale of Satisfaction with Communication in Everyday Speaking Situations (SCESS). The scale consists of one question which is simple, brief, easy to administer, cost-free, and translatable into many languages. The present report develops the SCESS scale by determining its reliability, content validity, and construct validity.

RESULTS

Reliability, content validity, and construct validity of the SCESS were confirmed with statistically significant and substantive correlations with speech-related and anxiety-related measures. However, the SCESS did not correlate well with percentage syllables stuttered. Three behavioral and psychosocial measures had the highest correlation with the SCESS: total Overall Assessment of the Speaker's Experience of Stuttering, self-reported stuttering severity, and Unhelpful Thoughts and Beliefs about Stuttering.

CONCLUSION

The SCESS measure has potential to be applied as an overarching clinical trial outcome measure of stuttering treatment effect. This study provides some preliminary evidence for including it as a primary or secondary outcome in clinical trials of adult stuttering treatments. However, further studies are needed to establish the SCESS responsiveness to different stuttering treatments.

A cluster randomised trial of a classroom communication resource program to change peer attitudes towards children who stutter among grade 7 students

Background

Classroom-based stuttering intervention addressing negative peer attitudes, perceptions, teasing and bullying of children who stutter (CWS) is required as part of holistic stuttering management because of its occurrence in primary school. This study was conducted in 2017, in 10 primary schools in the Western Cape, South Africa within lower (second and third) and higher (fourth and fifth) quintiles.

Objectives

The primary objective of this study was to determine treatment effect at six months after intervention of grade 7 participants (Classroom Communication Resource [CCR] intervention versus no CCR) using global Stuttering Resource Outcomes Measure (SROM) scores in school clusters. The secondary objective was to determine grade 7 participant treatment effect on the SROM subscales including Positive Social Distance (PSD), Social Pressure (SP) and Verbal Interaction (VI). The subgroup objective was to determine any difference in the primary outcome between schools between and across quintile clusters (lower and higher).

Methods

Once schools were stratified into lower and higher quintile (which are defined according to geographical location, fee per school and resources) subgroup clusters, schools were assigned randomly to control and intervention groups consisting of grade 7 participants who were typically aged ≥ 11 years. Teachers received 1 h of training before administering the single-dose CCR intervention over a 60–90-min session. The CCR intervention included a social story, role-play and discussion. All participants viewed a video of a CWS and stuttering was defined at baseline. The SROM measured peer attitudes at six months after intervention. Randomisation was stratified by quintile group using a 1:1 allocation ratio. Full blinding was not possible; however, the outcome assessor was partially blinded and the analyst was also blinded. Generalised estimating equations (GEE) was used assuming an exchangeable correlation structure to analyse the data adopting an intention-to-treat principle. Multiple imputation was used to handle missing data. Criterion for statistical significance was set at alpha = 0.05.

Results

Ten schools were randomly allocated to control (k = 5) and intervention groups (k = 5), with n = 223 participants allocated to intervention and n = 231 to control groups. A total of 454 participants completed the SROMs in control (n = 231) and intervention (n = 223) groups and were analysed at baseline and six months after intervention. There was no statistically significant difference on the global SROM score (mean difference − 0.11; 95% confidence interval [CI] − 1.56–1.34; p = 0.88). There were also no significant differences on SROM subscales: PSD (mean difference 1.04; 95% CI − 1.02–311; p = 0.32), SP (mean difference − 0.45; 95% CI − 1.22–0.26; p = 0.21) and VI (mean difference 0.05; 95% CI − 1.01–1.11; p = 0.93). Additionally, there was no significant subgroup effect on the global SROM score (lower versus higher quintile subgroups) (interaction p value = 0.52). No harms were noted or reported.

Conclusion

No statistically significant differences were noted. It is possible that the time frame was too short to note changes in peer attitudes and that further study is required to confirm the findings of this study.
