Enhancing Pragmatic Language skills for Young children with Social communication difficulties (E-PLAYS-2) trial: study protocol for a cluster-randomised controlled trial evaluating a computerised intervention to promote communicative development and collaborative skills in young children.

BACKGROUND: A number of children experience difficulties with social communication and this has long-term deleterious effects on their mental health, social development and education. The E-PLAYS-2 study will test an intervention ('E-PLAYS') aimed at supporting such children. E-PLAYS uses a dyadic computer game to develop collaborative and communication skills. Preliminary studies by the authors show that E-PLAYS can produce improvements in children with social communication difficulties on communication test scores and observed collaborative behaviours. The study described here is a definitive trial to test the effectiveness and cost-effectiveness of E-PLAYS delivered by teaching assistants in schools. METHODS: The aim of the E-PLAYS-2 trial is to establish the effectiveness and cost-effectiveness of care as usual plus the E-PLAYS programme, delivered in primary schools, compared to care as usual. Cluster-randomisation will take place at school level to avoid contamination. The E-PLAYS intervention will be delivered by schools' teaching assistants. Teachers will select suitable children (ages 5-7 years old) from their schools using guidelines provided by the research team. Assessments will include blinded language measures and observations (conducted by the research team), non-blinded teacher-reported measures of peer relations and classroom behaviour and parent-reported use of resources and quality of life. A process evaluation will also include interviews with parents, children and teaching assistants, observations of intervention delivery and a survey of care as usual. The primary analysis will compare pragmatic language scores for children who received the E-PLAYS intervention versus those who did not at 40 weeks post-randomisation. Secondary analyses will assess cost-effectiveness and a mixed methods process evaluation will provide richer data on the delivery of E-PLAYS. DISCUSSION: The aim of this study is to undertake a final, definitive test of the effectiveness of E-PLAYS when delivered by teaching assistants within schools. The use of technology in game form is a novel approach in an area where there are currently few available interventions. Should E-PLAYS prove to be effective at the end of this trial, we believe it is likely to be welcomed by schools, parents and children.

Dispositivos generadores de voz controlados con la mirada / Voice generating devices gaze controlled

CONTEXTO CLÍNICO: Un trastorno en la comunicación es un deterioro en la capacidad de recibir, transmitir, procesar y comprender conceptos o sistemas de símbolos verbales, no verbales y gráficos. Estos trastornos pueden ser evidentes en los procesos de audición, lenguaje o habla, y podrían variar en su severidad de leve a profunda y tener su origen en el desarrollo o ser adquiridos. Los individuos pueden presentar una o cualquier combinación, y dichos trastornos a su vez pueden ser primarios o secundarios a otras condiciones. Un trastorno en el lenguaje es el deterioro de la comprensión y/o el uso del lenguaje hablado, escrito o simbólico.2 Dicho trastorno puede incluir la forma del lenguaje (fonación, morfología y sintaxis), el contenido (semántica), y la función del lenguaje en la comunicación (habilidades pragmáticas) en cualquier combinación. Hay múltiples condiciones que se asocian a trastornos del lenguaje en niños y adolescentes. Entre estas se encuentran el retardo mental, los trastornos del aprendizaje, el trastorno de déficit de atención por hiperactividad, los trastornos del espectro autista, los desórdenes neurológicos degenerativos, la parálisis cerebral, síndrome de Rett y los traumatismos del sistema nervioso central entre otras. En los adultos las causas más frecuentes son, el accidente cerebrovascular, la esclerosis lateral amiotrófica (ELA), la enfermedad de Parkinson y también las lesiones traumáticas del sistema nervioso central (SNC). TECNOLOGÍA: Los dispositivos generadores de voz controlados con la mirada son sistemas de comunicación alternativa y aumentativa de alta tecnología que en general forman parte sistemas de tecnología de apoyo que incluyen otras funciones como control ambiental, el acceso informático a Internet, realizar llamadas telefónicas y enviar mensajes de texto.10 Existen los rastreadores oculares (PCEye Mini, PCEye Explore y EyeMobile, Irisbond®, myGAZE, PRC's LookTM, entre otros) que se pueden acoplar a diferentes dispositivos electrónicos como computadoras o tablets y los dispositivos generadores de voz con pantalla táctil y rastreo ocular incorporado (Tobii Dynavox I-Series+, Eyegaze Edge®, ComLink ST3G Enable Eyes II®). OBJETIVO: El objetivo del presente informe es evaluar la evidencia disponible acerca de la eficacia, seguridad y aspectos relacionados a las políticas de cobertura del uso de los dispositivos generadores de voz controlados con la mirada para patologías que afectan el lenguaje, el habla y las habilidades motrices. MÉTODOS: Se realizó una búsqueda en las principales bases de datos bibliográficas, en buscadores genéricos de internet, y financiadores de salud. Se priorizó la inclusión de revisiones sistemáticas (RS), ensayos clínicos controlados aleatorizados (ECAs), evaluaciones de tecnologías sanitarias (ETS), evaluaciones económicas, guías de práctica clínica (GPC) y políticas de cobertura de diferentes sistemas de salud. RESULTADOS: Se incluyeron una RS de estudios observacionales, siete estudios observacionales adicionales, cuatro GPC y diez informes de políticas de cobertura de los dispositivos generadores de voz controlados con la mirada para patologías que afectan el lenguaje, el habla y las habilidades motrices. Las definiciones de los desenlaces y las escalas utilizadas en los estudios se describen en el Anexo II. No se hallaron estudios que comparen los distintos tipos de dispositivos generadores de voz con rastreo ocular entre sí o frente al cuidado usual. Tampoco se hallaron estudios que compararan los dispositivos generadores de voz operados mediante movimiento ocular con otros dispositivos generadores de voz operados de diferentes maneras. CONCLUSIONES: No se hallaron estudios que comparen los distintos tipos de dispositivos generadores de voz controlados por la mirada entre sí, u operados de diferentes maneras. Tampoco se hallaron estudios que comparen su uso frente al cuidado usual. Evidencia de baja calidad, proveniente de estudios de serie de casos, sugiere que la implementación de los dispositivos generadores de voz controlados con la mirada mejoraría algunos aspectos de la comunicación en personas con discapacidades motoras y del habla complejas (como parálisis cerebral, esclerosis lateral amiotrófica y síndrome de Rett). Estas mejoras se evidenciaron respecto al estado basal, a los seis meses de seguimiento, en el contexto de clínicas de rehabilitación y con un equipo tratante multidisciplinario especializado. Resultados similares fueron reportados por la familia o cuidadores. La mayoría de los estudios reportaron una alta tasa de aceptación de la tecnología, aunque algunos también identificaron dificultades para establecer una comunicación en personas con episodios de epilepsia y temblores. También se reportaron dificultades como incomodidad, cansancio y aburrimiento en los usuarios. Las guías de práctica clínicas relevadas establecen que la comunicación alternativa y aumentativa, donde mencionan a los dispositivos generadores de voz controlados con la mirada, es necesaria en aquellos pacientes con afectación del lenguaje y del habla. Estos dispositivos no están mencionados explícitamente en el Programa Médico Obligatorio, el Sistema Único de Reintegro de la Superintendencia de Servicios de Salud o la Ley de discapacidad de Argentina, ni en ninguna de las políticas de cobertura de los países de Latinoamérica relevadas. De las políticas de cobertura de países de altos ingresos relevadas, solo Estados Unidos y Reino Unido mencionan los dispositivos generadores de voz controlados con la mirada para las indicaciones evaluadas. No se hallaron estudios económicos (ni para Argentina ni para otros países) por lo que su costo-efectividad o impacto presupuestario resulta incierta.

Apps As Learning Tools: A Systematic Review.

CONTEXT: Young children have increasing access to interactive applications (apps) at home and at school. Existing research is clear on the potential dangers of overuse of screens, but there is less clarity around the extent to which interactive apps may be helpful in supporting early learning. OBJECTIVE: In this systematic review, we present a narrative synthesis of studies examining whether children <6 years can learn from interactive apps. DATA SOURCES: The PsycInfo, PubMed, ACM Digital Library, and ERIC databases were searched. STUDY SELECTION: Studies were included if the study design was randomized or nonrandomized controlled (quasi-experimental), the sample mean age was <6 years, the intervention involved children playing with an interactive app, and academic, cognitive, or social-emotional skill outcomes were measured. DATA EXTRACTION: Of 1447 studies, 35 were included. RESULTS: Evidence of a learning benefit of interactive app use for early academic skills was found across multiple studies, particularly for early mathematics learning in typically developing children. Researchers did not find evidence of an intervention effect for apps aiming to improve social communication skills in children with autism spectrum disorder. LIMITATIONS: Risk of bias was unclear for many studies because of inadequate reporting. Studies were highly heterogenous in interventions, outcomes, and study design, making comparisons of results across studies difficult. CONCLUSIONS: There is emerging evidence to suggest that interactive apps may be useful and accessible tools for supporting early academic development. More research is needed to evaluate both the potential of educational apps to support early learning, and their limitations.

Intensive and standard group-based treatment for persons with social communication difficulties after an acquired brain injury: study protocol for a randomised controlled trial.

INTRODUCTION: Social communication difficulties (SCDs) occur frequently after an acquired brain injury (ABI) and have disabling consequences, but effective interventions are scant. Group Interactive Structured Treatment (GIST) is a holistic group treatment targeting SCD that has received empirical support. OBJECTIVE: To determine the efficacy of two GIST protocols, standard GIST and a newly developed intensive GIST, comparing standard GIST results to a wait-list control group (WL), as well as to intensive GIST received by participants following WL. The within subject results for WL and intensive GIST will also be examined. METHODS AND ANALYSIS: Sixty adults (18-75 years) with SCD after ABI will be recruited for this randomised controlled trial. Standard GIST (n=30) will be delivered via outpatient sessions for 2.5 hours once per week for 12 weeks, plus one initial orientation session. Participants will be assessed at preintervention and postintervention and at 3-month and 6-month follow-ups (T1-T4). Intensive GIST (n=30) participants will be admitted to an inpatient rehabilitation unit for 4 weeks (two times 3 days/week, two times 4 days/week) and receive full-day sessions each week. Those participants will complete four assessments (T1-T4) in 12-week intervals as part of WL, assessments preintensive and postintensive GIST and at 3-month and 6-month follow-ups (T4-T7). The primary outcome measure is the La Trobe Questionnaire (self-report). Secondary outcome measures include the Profile of Pragmatic Impairment in Communication, a test of emotion recognition, the Goal Attainment Scale and questionnaires addressing social, emotional and cognitive functions, self-efficacy and quality of life. ETHICS AND DISSEMINATION: Results will be communicated through international, peer-reviewed and popular science journals and presentations at scientific conferences. The study is approved by the Regional Committees for Medical and Health Research Ethics Norway (2017/1360). The trial will be conducted in accordance with the Declaration of Helsinki and reported in accordance with the Consolidated Standards of Reporting Trials 2010 statement and Standard Protocol Items: Recommendations for Interventional Trials recommendations. TRIAL REGISTRATION NUMBER: NCT03636399.

Social communication following traumatic brain injury part I: State-of-the-art review of assessment tools.

PURPOSE: The primary aim of this paper was to identify and describe current social communication assessment tools for adults with traumatic brain injury. METHOD: We conducted a state-of-the-art review to identify and categorise the range of social communication assessment tools found in the assessment and treatment literature that revealed 42 measures that were coded according to characteristics related to assessment types, psychometrics, and implementation. RESULT: Of the 42 assessments, 64% evaluated social cognition and the remaining 36% evaluated communication. Coding of implementation categories revealed that only 18/42 (43%) measures were ecologically grounded and 23/42 (55%) were available to clinicians by purchase or in the public domain. Only three measures incorporated questions or an assessment of the examinee's priorities or concerns. CONCLUSION: A number of factors limit current social communication assessment. The lack of tools that objectively and reliably evaluate communication or social cognition in ecologically valid ways remains problematic. Of particular concern is the lack of prioritisation of the individual's communication values and needs. Recommendations include a call to focus research on the development of more contextual, standardised assessments, consider availability and feasibility when tools are being developed, and evaluate assessment processes as well as discrete tools.

Social communication following traumatic brain injury part 2: Identifying effective treatment ingredients.

PURPOSE: Social communication deficits are a severely debilitating aspect of traumatic brain injury (TBI), and there is strong clinical and research interest in how social communication interventions work for this population. Informed by a companion paper targeting assessment of social communication impairments post-TBI, this paper reviews relevant treatment theories and provides an inventory of social communication treatment components. METHOD: We completed a mapping review examining 17 articles from recent literature reviews and 4 updated articles from a literature search to identify treatment targets and ingredients using the Rehabilitation Treatment Specification System (RTSS). RESULT: Social communication interventions are primarily based on behavioural and cognitive treatment theories. Common social communication treatment targets include changing skilled behaviours and cognitive or affective representations. We offer a menu of therapeutic ingredients and treatment considerations which represent the current state of social communication interventions. CONCLUSION: By reviewing the social communication intervention literature through a theoretical lens, we identify which treatment targets are missing, which targets are being addressed, and which therapeutic ingredients (i.e. clinician activities) are recommended. A hypothetical case study is provided as a supplement to demonstrate how speech-language pathologists may integrate treatment theory, ingredients, and targets into clinical practice.

Application of the Communication Complexity Scale in Peer and Adult Assessment Contexts for Preschoolers With Autism Spectrum Disorders.

Purpose The purpose of this study was to measure changes in communication of preschoolers with autism using the Communication Complexity Scale (CCS; Brady et al., 2012 ) and to examine the utility of the CCS in measuring pretreatment and posttreatment changes within peer and adult assessment contexts. Method The CCS was used to code preassessment and postassessment for 23 children with autism randomly assigned to a treatment that incorporated a peer-mediated approach and a speech-generating device and 22 assigned to a business-as-usual condition with untrained peers. Children were assessed in 2 structured 30-min contexts-1 with an adult examiner and 1 with a peer partner coached by an adult. Results Children in both groups showed significant changes in communication complexity CCS scores from pretreatment to posttreatment in the adult and peer contexts. At both occasions, CCS scores were higher with adult partners yet showed greater improvements over time with peer partners. Conclusions Results showed that the CCS was sensitive to change over time but did not discriminate changes in communication complexity associated with maturation versus treatment. It did show some differences based on interactions with peer versus adult partners. Outcomes provide preliminary support for using this scale to measure communication changes in different contexts.

A pilot community-based randomized comparison of speech generating devices and the picture exchange communication system for children diagnosed with autism spectrum disorder.

A pilot community-based randomized controlled trial was conducted to compare the effects of the Picture Exchange Communication System (PECS) to a teaching sequence using a high-tech Speech Generating Device (SGD) to teach social communication behaviors. The two approaches were compared to evaluate the effectiveness of the newer, more high-tech intervention using technology to improve social and communicative behavior of children diagnosed with Autism Spectrum Disorder. A total of 35 school-age children were randomized to either a high-tech (SGD device) or low-tech (PECS cards) form of Augmentative and Alternative Communication (AAC). Study participants received 4 months of communication training delivered in their classrooms, and the primary outcome measures of the trial were several functional communication skills emphasized in the PECS teaching sequence. Results indicated that both high-tech and low-tech AAC approaches resulted in significant improvements in communication, and that these improvements did not differ significantly between the two approaches. These findings support the use of high-tech AAC, and highlight the need for evidence-based guidelines for its use as well as evaluation with individuals with a range impairments and disabilities. Autism Research 2018, 11: 1701-1711. © 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This study compared the effectiveness of a free and open-source app for teaching social and communicative behavior to children with autism spectrum disorder (ASD) to traditional picture card approaches. Thirty-five children with ASD were randomized to a picture card or app-based intervention and both treatment approaches resulted in significant improvements in social and communicative behavior. These data indicated that both "high-tech" and "low-tech" interventions were effective for improving behavior and that there was not a significant difference between the two approaches.

Efficacy of the ASAP Intervention for Preschoolers with ASD: A Cluster Randomized Controlled Trial.

The advancing social-communication and play (ASAP) intervention was designed as a classroom-based intervention, in which the educational teams serving preschool-aged children with autism spectrum disorder are trained to implement the intervention in order to improve these children's social-communication and play skills. In this 4-year, multi-site efficacy trial, classrooms were randomly assigned to ASAP or a business-as-usual control condition. A total of 78 classrooms, including 161 children, enrolled in this study. No significant group differences were found for the primary outcomes of children's social-communication and play. However, children in the ASAP group showed increased classroom engagement. Additionally, participation in ASAP seemed to have a protective effect for one indicator of teacher burnout. Implications for future research are discussed.

Metacognition in speech and language therapy for children with social (pragmatic) communication disorders: implications for a theory of therapy.

BACKGROUND: Metacognition is a significant component of complex interventions for children who have developmental language disorders. Research into how metacognition operates in the content or process of developmental language therapy delivery is limited. Identification and description of proposed active therapy components, such as metacognition, may contribute to our understanding of how to deliver complex communication interventions in an optimal manner. AIMS: To analyse aspects of metacognition during therapy derived from a manualized speech and language intervention (the Social Communication Intervention Programme-SCIP) as delivered to children who have social (pragmatic) communication disorder (SPCD) and to examine the dynamic process of delivering therapy. METHODS & PROCEDURES: A purposive sample of eight filmed therapy sessions was selected from the video data corpus of intervention-arm participants within a randomized controlled trial. The child-therapist interactions during therapy sessions from five children (aged between 5;11 and 10;3) in the SCIP trial were transcribed. Filmed sessions represented a variety of communication profiles and SCIP therapy content. Starting from existing theory on metacognition, cycles of iterative analysis were performed using a mixed inductive-deductive qualitative analysis. A preliminary list of metacognitive content embedded in the intervention was developed into a metacognitive coding framework (MCF). A thematic analysis of the identified metacognitive content of the intervention was then carried out across the whole sample. OUTCOMES & RESULTS: Thematic analysis revealed the presence of metacognition in the content and delivery of SCIP intervention. Four main themes of metacognitive person, task and strategy knowledge, and monitoring/control were identified. Metacognition was a feature of how children's ability to monitor language, pragmatic and social interaction skills, in themselves and other people, was developed. Task design and delivery methods were found to play a particular role in adjusting the metacognitive content of the therapy activities. CONCLUSIONS & IMPLICATIONS: This study makes explicit the metacognitive content and delivery within a complex developmental communication intervention. Discussion of the findings about metacognitive content provides an explanation of how the skilled speech and language therapist manipulates task demands, person knowledge and therapy methods towards the therapy goal. Clinical applications of the metacognitive framework are discussed. We suggest that the process of making the tacit knowledge of the therapist explicit can contribute to the implementation of complex evidence-based interventions.

Communicative development of Portuguese infants aged between 8 and 15 months / Desarrollo comunicativo de los niños portugueses con edades comprendidas entre los 8 y los 15 meses

The main aim of this study was to investigate the development of gesture and language acquisition in European Portuguese infants. These were assessed using the European Portuguese MacArthur-Bates Communicative Development Inventory: words and gestures. The parents’ reports of gestures and lexical competence of 1314 children, aged between 8 and 15 months, were collected. As expected, the results indicated that word comprehension, word production, and the use of gestures increased with age. A main gender effect was found for total gestures, with girls obtaining higher scores than boys, but the effect size was small. No differences were found between girls and boys for word comprehension, word production, and phrases understood. All lexical and gesture measurements were positively correlated, even after controlling for age and gender effects. These findings are discussed in terms of their consistency with those obtained for other languages (AU)

El objetivo principal de este estudio fue investigar el desarrollo de gestos y la adquisición del lenguaje en niños hablantes de portugués europeo. Los gestos y los conocimientos lingüísticos de los niños se evaluaron utilizando la versión en Portugués Europeo del Inventario de Desarrollo Comunicativo MacArthur-Bates: palabras y gestos. Se recogieron los informes paternos de los gestos y competencia léxica de 1,314 niños, con edades comprendidas entre los 8 y los 15 meses. Como era esperable, los resultados indican que la comprensión de palabras, la producción de palabras y el uso de gestos aumentan con la edad. Se encontró también un efecto principal del género para el total de gestos, obteniendo las niñas puntuaciones más altas que los niños, pero el tamaño del efecto es pequeño. No se encontraron diferencias entre niños y niñas para la comprensión y producción de palabras y para frases entendidas. Todas las medidas de léxico y gestos están correlacionadas positivamente, incluso después de controlar los efectos de la edad y del género. Estos resultados se discuten en términos de su consistencia con los obtenidos para otros idiomas (AU)

Characterizing social communication changes in amyotrophic lateral sclerosis.

BACKGROUND: Speech and language impairments are well-established in individuals with amyotrophic lateral sclerosis (ALS). However, knowledge about particular aspects of social communication and everyday conversational abilities is limited. AIMS: To investigate self- and informant-report ratings of social communicative abilities in ALS participants and matched healthy controls. METHODS & PROCEDURES: Thirty-two participants with ALS and 24 controls completed the La Trobe Communication Questionnaire (LCQ). Participants nominated a close other to provide an informant report on the LCQ. Demographic and clinical information was also collected. OUTCOMES & RESULTS: Informant ratings indicated greater difficulties in conversational initiation, effectiveness and partner sensitivity for ALS participants compared with controls. ALS participants did not rate their social communicative abilities as poorer than controls and self-reports only differed from informant ratings in the control group. LCQ scores were not significantly correlated with clinical/functional variables. CONCLUSIONS & IMPLICATIONS: Social communication can be reduced in ALS and individuals may lack insight into these difficulties. In order to understand and provide targeted interventions for such difficulties, clinical speech and language assessment should incorporate social communication assessment, including both a self- and informant-report format.

Identifying mechanisms of change in a conversation therapy for aphasia using behaviour change theory and qualitative methods.

BACKGROUND: Conversation therapy for aphasia is a complex intervention comprising multiple components and targeting multiple outcomes. UK Medical Research Council (MRC) guidelines published in 2008 recommend that in addition to measuring the outcomes of complex interventions, evaluation should seek to clarify how such outcomes are produced, including identifying the hypothesized mechanisms of change. AIMS: To identify mechanisms of change within a conversation therapy for people with aphasia and their partners. Using qualitative methods, the study draws on behaviour change theory to understand how and why participants make changes in conversation during and after therapy. METHODS & PROCEDURES: Data were derived from 16 participants (eight people with aphasia; eight conversation partners) who were recruited to the Better Conversations with Aphasia research project and took part in an eight session conversation therapy programme. The dataset consists of in-therapy discussions and post-therapy interviews, which are analysed using Framework Analysis. OUTCOMES & RESULTS: Seven mechanisms of conversational behaviour change are identified and linked to theory. These show how therapy can activate changes to speakers' skills and motivation for using specific behaviours, and to the conversational opportunities available for strategy use. CONCLUSIONS & IMPLICATIONS: These clinically relevant findings offer guidance about the processes involved in producing behavioural change via conversation therapy. A distinction is made between the process involved in motivating change and that involved in embedding change. Differences are also noted between the process engaged in reducing unhelpful behaviour and that supporting new uses of compensatory strategies. Findings are expected to have benefits for those seeking to replicate therapy's core processes both in clinical practice and in future research.

Conversation breakdowns in the audiology clinic: the importance of mutual gaze.

BACKGROUND: Conversational breakdowns are a persistent concern for older adults with hearing impairment (HI). Previous studies in experimental settings have investigated potential causes of breakdowns in conversations with a person with HI, and effective strategies for repairing these breakdowns. However, little research has explored the causes of hearing-related communication breakdowns, and their repairs, in extended, naturally occurring conversations in a healthcare setting. AIMS: To analyse systematically instances of clients' initiations of repair within video-recorded initial audiology appointments, and to examine the interactional environment in which they occurred. METHODS & PROCEDURES: Participants included 26 audiologists and their older adult clients (aged 55+ years). Companions were present in 17 of the 63 appointments. Conversation analysis (CA) was used to examine the video-recorded audiology appointments with older adults with HI. The corpus was systematically analysed for all instances of 'other-initiated repair' by clients (initiation of repair targeting the prior speakers' turn). A collection of 51 instances of other-initiated repair were identified. These instances were analysed in detail for: (1) the interactional environment in which they occurred; (2) the strategy by which the client initiated repair; and (3) the strategies used by the audiologist to repair the communication breakdown. OUTCOMES & RESULTS: In 76% (n = 39) of the 51 cases of other-initiated repair from the client, there was a lack of mutual gaze between participants (i.e., either the audiologist or the client were looking away or facing in another direction during the prior turn). More specifically, many of these instances occurred when the audiologist was speaking to the client while multitasking. Audiologists used multiple-repair strategies in their responsive turn in an attempt to repair the communication breakdown efficiently. CONCLUSIONS & IMPLICATIONS: These findings, from extended, naturally occurring conversations with older adults with HI in clinic settings, highlight the importance of face-to-face communication even in quiet one-to-one settings. Clinicians should remain aware of their movements and gaze when speaking to clients during appointments. The findings also provide further support for the importance of communication programs in hearing rehabilitation.

Joint attention interventions for children with autism spectrum disorder: a systematic review and meta-analysis.

BACKGROUND: A core social-communication deficit in children with autism spectrum disorder (ASD) is limited joint attention behaviours-important in the diagnosis of ASD and shown to be a powerful predictor of later language ability. Various interventions have been used to train joint attention skills in children with ASD. However, it is unclear which participant, intervention and interventionist factors yield more positive results. AIMS: The purpose of this systematic review and meta-analysis was to provide a quantitative assessment of the effectiveness of joint attention interventions aimed at improving joint attention abilities in children with ASD. METHODS & PROCEDURES: The researchers searched six databases for studies meeting the inclusion criteria at two levels: title/abstract and full-text stages. Two independent coders completed data extraction using a coding manual and form developed specifically for this research study. Meta-analysis procedures were used to determine the overall effects of several comparisons including treatment type, treatment administrator, intervention characteristics and follow-up. MAIN CONTRIBUTION: Fifteen randomized experimental studies met inclusion criteria. All comparisons resulted in statistically significant effects, though overlapping confidence intervals suggest that none of the comparisons were statistically different from each other. Specifically, treatment administrator, dosage and design (control or comparison, etc.) characteristics of the studies do not appear to produce significantly different effects. CONCLUSIONS & IMPLICATIONS: The results of this meta-analysis provide strong support for explicit joint attention interventions for young children with ASD; however, it remains unclear which children with ASD respond to which type of intervention.

Clinical assessment of social cognitive function in neurological disorders.

Social cognition broadly refers to the processing of social information in the brain that underlies abilities such as the detection of others' emotions and responding appropriately to these emotions. Social cognitive skills are critical for successful communication and, consequently, mental health and wellbeing. Disturbances of social cognition are early and salient features of many neuropsychiatric, neurodevelopmental and neurodegenerative disorders, and often occur after acute brain injury. Its assessment in the clinic is, therefore, of paramount importance. Indeed, the most recent edition of the American Psychiatric Association's Diagnostic and Statistical Manual for Mental Disorders (DSM-5) introduced social cognition as one of six core components of neurocognitive function, alongside memory and executive control. Failures of social cognition most often present as poor theory of mind, reduced affective empathy, impaired social perception or abnormal social behaviour. Standard neuropsychological assessments lack the precision and sensitivity needed to adequately inform treatment of these failures. In this Review, we present appropriate methods of assessment for each of the four domains, using an example disorder to illustrate the value of these approaches. We discuss the clinical applications of testing for social cognitive function, and finally suggest a five-step algorithm for the evaluation and treatment of impairments, providing quantitative evidence to guide the selection of social cognitive measures in clinical practice.

Performance of South African children on the Communication and Symbolic Behavior Scales-Developmental Profile (CSBS DP).

BACKGROUND: Substantial development in social communication skills occurs in the first two years of life. Growth should be evident in sharing emotion and eye gaze; rate of communication, communicating for a variety of functions; using gestures, sounds and words; understanding language, and using functional and pretend actions with objects in play. A delay in these early social communication skills may be the first sign of a developmental delay in young children in nearly all categories of disabilities-including specific language impairment, autism spectrum disorder, HIV/AIDS, lack of environmental stimulation or institutionalization, and global developmental delays-and early detection of these delays is critical for enrolment in appropriate early intervention services. AIMS: No standardized tests of early social communication skills exist for very young children in South Africa (SA). An existing evaluation tool that has the potential to be culturally fair for children from cultural backgrounds different to the standardization group is the Communication and Symbolic Behaviour Scales-Developmental Profile (CSBS DP). This study aimed to document the performance of a group of English-speaking SA children ranging in age from 12 to 24 months on the CSBS DP and to compare this performance with the original standardization sample. METHODS & PROCEDURES: Sixty-seven English-speaking SA children from a range of cultural and linguistic backgrounds were assessed on the CSBS DP Behaviour Sample. Group scores were compared with the original standardization sample using inferential statistics. OUTCOMES & RESULTS: The results provide preliminary support for the suitability and validity of the face-to-face Behaviour Sample as a measure of early social communication skills in this sample of English-speaking SA children from a range of cultural groups between 12 and 24 months of age. CONCLUSIONS & IMPLICATIONS: While further research in the SA population is needed, these findings are a first step towards validating a culturally appropriate measure for early detection of social communication delays in a sample of SA toddlers.

A Bioecological framework to evaluate communicative participation outcomes for preschoolers receiving speech-language therapy interventions in Ontario, Canada.

BACKGROUND: The Preschool Speech and Language Program (PSLP) in Ontario, Canada, is a publically funded intervention service for children from birth to 5 years with communication disorders. It has begun a population-level programme evaluation of children's communicative participation outcomes following therapy. Data are currently being collected for all children who access this service--over 50,000 children each year. AIMS: To understand and evaluate how therapeutic interventions in speech-language therapy impact the everyday lives of children and families by applying a theoretical framework. MAIN CONTRIBUTION: This discussion paper critically examines how the Bioecological Model of Development can be applied to the study of communicative participation outcomes following speech and language therapy. This model will be used in future analyses of communicative participation outcomes data in Ontario's PSLP. The strengths and challenges of this approach are reviewed.

Treatment intensity and childhood apraxia of speech.

BACKGROUND: Intensive treatment has been repeatedly recommended for the treatment of speech deficits in childhood apraxia of speech (CAS). However, differences in treatment outcomes as a function of treatment intensity have not been systematically studied in this population. AIM: To investigate the effects of treatment intensity on outcome measures related to articulation, functional communication and speech intelligibility for children with CAS undergoing individual motor speech intervention. METHODS & PROCEDURES: A total of 37 children (32-54 months of age) with CAS received 1×/week (lower intensity) or 2×/week (higher intensity) individual motor speech treatment for 10 weeks. Assessments were carried out before and after a 10-week treatment block to study the effects of variations in treatment intensity on the outcome measures. OUTCOMES & RESULTS: The results indicated that only higher intensity treatment (2×/week) led to significantly better outcomes for articulation and functional communication compared with 1×/week (lower intensity) intervention. Further, neither lower nor higher intensity treatment yielded a significant change for speech intelligibility at the word or sentence level. In general, effect sizes for the higher intensity treatment groups were larger for most variables compared with the lower intensity treatment group. CONCLUSIONS & IMPLICATIONS: Overall, the results of the current study may allow for modification of service delivery and facilitate the development of an evidence-based care pathway for children with CAS.

[Measuring impairment of facial affects recognition in schizophrenia. Preliminary study of the facial emotions recognition task (TREF)]. / Mesure du déficit de reconnaissance des émotions faciales dans la schizophrénie. Étude préliminaire du test de reconnaissance des émotions faciales (TREF).

INTRODUCTION: The impairment of social cognition, including facial affects recognition, is a well-established trait in schizophrenia, and specific cognitive remediation programs focusing on facial affects recognition have been developed by different teams worldwide. However, even though social cognitive impairments have been confirmed, previous studies have also shown heterogeneity of the results between different subjects. Therefore, assessment of personal abilities should be measured individually before proposing such programs. PURPOSE: Most research teams apply tasks based on facial affects recognition by Ekman et al. or Gur et al. However, these tasks are not easily applicable in a clinical exercise. Here, we present the Facial Emotions Recognition Test (TREF), which is designed to identify facial affects recognition impairments in a clinical practice. The test is composed of 54 photos and evaluates abilities in the recognition of six universal emotions (joy, anger, sadness, fear, disgust and contempt). Each of these emotions is represented with colored photos of 4 different models (two men and two women) at nine intensity levels from 20 to 100%. Each photo is presented during 10 seconds; no time limit for responding is applied. METHOD: The present study compared the scores of the TREF test in a sample of healthy controls (64 subjects) and people with stabilized schizophrenia (45 subjects) according to the DSM IV-TR criteria. We analysed global scores for all emotions, as well as sub scores for each emotion between these two groups, taking into account gender differences. Our results were coherent with previous findings. Applying TREF, we confirmed an impairment in facial affects recognition in schizophrenia by showing significant differences between the two groups in their global results (76.45% for healthy controls versus 61.28% for people with schizophrenia), as well as in sub scores for each emotion except for joy. Scores for women were significantly higher than for men in the population without psychiatric diagnosis. The study also allowed the identification of cut-off scores; results below 2 standard deviations of the healthy control average (61.57%) pointed to a facial affect recognition deficit. CONCLUSION: The TREF appears to be a useful tool to identify facial affects recognition impairment in schizophrenia. Neuropsychologists, who have tried this task, have positive feedback. The TREF is easy to use (duration of about 15 minutes), easy to apply in subjects with attentional difficulties, and tests facial affects recognition at ecological intensity levels. These results have to be confirmed in the future with larger sample sizes, and in comparison with other tasks, evaluating the facial affects recognition processes.
