Psychometric Properties of the Dutch Contextual Assessment of Social Skills (CASS): An Independent Observational Outcome Measure of Social Skills in Autistic Adolescents. Journal of autism and developmental disorders. 2023.

The goal of this study was to translate and adapt the original 9-item of the Contextual Assessment of Social Skills (CASS) to a Dutch version and assess its psychometric qualities. Autistic adolescents aged 12 to 18 years (n = 99) took part in a randomized controlled trial. In this study, pre-intervention data were utilized. The original CASS was adapted to ensure cultural relevance and the content validity was assessed. Data was used to assess reliability and structural validity, using confirmatory factor analysis. 4-item were added to the CASS during the adaptation to better align with the objectives of the experimental intervention. The original 9-item had inter-item correlations between .01 and .70. The Cronbach’s alpha for the original 4-item total score was moderate (α = .69), while for a 7-item total score, it was high (α = .86). This 7-item total score had a sufficient model fit (Comparative Fit Index = .90). This total score had a significant correlation with the Assertion subscale of the Social Skills Improvement System-Adolescent (SSIS-A) (r = 0.26, p < .01), and the Social Responsiveness Scale-2 (SRS-2) total score (r = - .21, p = .04) indicating sufficient convergent validity. The CASS total score was not correlated with the Repetitive and Restricted Behavior scale of the SRS-2 (r = - .08, p = .43), indicating sufficient divergent validity. The Dutch CASS can be considered a conceptually sound and reliable observational instrument for assessing social conversational skills in Dutch autistic youth. Further evaluation of its feasibility when implemented in practice, outside of clinical research, is needed.Trial registration: Dutch trail register NTR6255 (NL6117) 08/02/2017 https://www.trialregister.nl/trial/6117.

2. Soan S, Lindblom A, Dindar K, Kärnä E, Carew MT. Student Teachers’ Positive Perceptions of Characteristics and Personality of People on the Autism Spectrum: « Challenging in a Positive Way ». Journal of autism and developmental disorders. 2023.

This paper presents quantitative and qualitative findings from an interdisciplinary research project exploring student teachers’ positive perceptions of people on the autism spectrum. The set of findings reported in this paper asked 704 student teachers from one university in England (n = 191), Finland (n = 251) and Sweden (n = 262) to write down the first three words they thought of to identify the characteristics of people on the autism spectrum. Data was analysed using a multi-layered, deductive co-rated coding approach. Through this approach repeated words were extracted as were negative and undetermined words, leaving only positive words. Examination of the positive words identified found differences in the manner student teachers focus on the positive characteristics of people on the autism spectrum as this is an understudied area of research. Finnish student teachers more frequently used language to describe the positive characteristics of people on the autism spectrum that reflected their perception of learning being their primary professional role. However, English and Swedish student teachers used language that showed they perceived their role as encompassing the social and emotional development of their pupils, with little reflection about the positive characteristics of people on the autism spectrum as learners.

3. Song Y, Nie Z, Shan J. Comprehension of irony in autistic children: The role of theory of mind and executive function. Autism research : official journal of the International Society for Autism Research. 2023.

Although previous studies have examined irony comprehension in autistic children and potential impact factors, the relationship between theory of mind (ToM), executive function (EF), symptoms of autism, and comprehension of irony in this population remains largely unknown. This study explored irony comprehension in autistic children and examined the roles of ToM and EF in linking autism symptoms to deficits in irony comprehension. Twenty autistic children were compared with 25 typically developing (TD) children in an irony story picture task, ToM task, and EF task. The results showed that autistic children had impaired comprehension of irony compared with TD children, and performance on ironic stories showed a significant moderate discriminatory effect in predicting autistic children. A ToM deficit has also been proposed for autistic children. Comprehension of irony was significantly correlated with second-order ToM (2nd ToM) but was not significantly correlated with any components of EF. Moreover, 2nd ToM can predict the level of irony comprehension and mediate the relationship between symptoms of autism and irony comprehension. Taken together, these findings suggest that irony comprehension may offer a potential cognitive marker for quantifying syndrome manifestations in autistic children, and 2nd ToM may provide insight into the theoretical mechanism underlying the deficit in irony comprehension in this population.

PURPOSE: Previous studies have demonstrated that physical exercise can modulate the endogenous melatonin level in children with autism spectrum disorder (ASD) and improve their sleep quality. However, it remains unclear whether physical exercise or melatonin supplement, or a combination of both, is more effective in improving sleep quality in this population. The purpose of this study is to answer this research question by comparing the effectiveness of three types of interventions (physical exercise vs. melatonin supplement or a combination of both) in improving sleep quality in children with ASD. METHODS: Sixty-two (62) children diagnosed with ASD were randomly assigned to one of four groups: cycling (n = 18), melatonin supplement (n = 14), a combination of both (n = 12), and placebo control group (n = 18). Four (4) sleep parameters (sleep efficiency, sleep onset latency, sleep duration, and wake after sleep onset) were assessed. RESULTS: The results revealed a significant improvement in sleep efficiency, sleep onset latency, and sleep duration in all of the interventions, but not in the placebo control group. However, no significant group differences were found among the interventions (ps > .05). CONCLUSION: Our findings suggest similar effectiveness of physical exercise and melatonin supplementation in improving sleep quality in children with ASD.

AIMS: To describe Indonesian nurses’ educational experience regarding care for people with intellectual disability and/or autism and to explore if these educational experiences are associated with their self-perceived confidence, comfort, knowledge and preparedness to care for these cohorts. DESIGN: Cross-sectional descriptive survey. METHODS: A descriptive survey tool utilized in a study of Australian registered nurses was replicated and adapted for this study. Following descriptive analysis, chi-square analyses were undertaken to explore associations between educational experiences, and self-rated measures of confidence, comfort and knowledge to work with people with intellectual disability and/or autism. Although there was no end-user involvement in the design of the study, the concepts explored have all been raised by those with lived insights of intellectual disability and/or autism as being critical to their healthcare experiences. RESULTS: There were 544 complete responses, and 51.7% were not exposed to any educational or clinical content relevant to caring for people with intellectual disability and/or autism. Moderate to low levels of self-perceived confidence, comfort, knowledge and preparedness to address healthcare needs of these cohorts were reported. Significant associations were identified between educational and clinical experiences during undergraduate training, and higher levels of self-perceived confidence, comfort and knowledge. CONCLUSION: Mirroring international literature, the findings of this study highlight a large proportion of Indonesian nurses had little educational experience relevant to caring for people with intellectual disability and/or autism, and have relatively low levels of self-reported capability. IMPACT: This study highlights gaps in the educational experiences, and self-perceived confidence, comfort, knowledge and preparedness of Indonesian nurses regarding caring for people with intellectual disability and/or autism. Given that internationally, people with intellectual disability and/or autism have disproportionately negative health outcomes and experiences, these findings have substantial implications for nursing curriculum, policy and professional development.

Autism spectrum disorder (ASD) is characterized by etiological and phenotypic heterogeneity. Despite efforts to categorize ASD into subtypes, research on specific functional connectivity changes within ASD subgroups based on clinical presentations is limited. This study proposed a symptom-based clustering approach to identify subgroups of ASD based on multiple clinical rating scales and investigate their distinct Electroencephalogram (EEG) functional connectivity patterns. Eyes-opened resting-state EEG data were collected from 72 children with ASD and 63 typically developing (TD) children. A data-driven clustering approach based on Social Responsiveness Scales-Second Edition and Vinland-3 scores was used to identify subgroups. EEG functional connectivity and topological characteristics in four frequency bands were assessed. Two subgroups were identified: mild ASD (mASD, n = 37) and severe ASD (sASD, n = 35). Compared to TD, mASD showed increased functional connectivity in the beta band, while sASD exhibited decreased connectivity in the alpha band. Significant between-group differences in global and regional topological abnormalities were found in both alpha and beta bands. The proposed symptom-based clustering approach revealed the divergent functional connectivity patterns in the ASD subgroups that was not observed in typical ASD studies. Our study thus provides a new perspective to address the heterogeneity in ASD research.
