Titre : Do Adults with High Functioning Autism or Asperger Syndrome Differ in Empathy and Emotion Recognition? Type de document : Texte imprimé et/ou numérique Auteurs : Charlotte B. MONTGOMERY, Auteur ; Carrie ALLISON, Auteur ; Meng-Chuan LAI, Auteur ; Sarah A. CASSIDY, Auteur ; Peter E. LANGDON, Auteur ; Simon BARON-COHEN, Auteur Article en page(s) : p.1931-1940 Langues : Anglais (eng) Mots-clés : Autism Asperger Empathy Emotion DSM-5 Index. décimale : PER Périodiques Résumé : The present study examined whether adults with high functioning autism (HFA) showed greater difficulties in (1) their self-reported ability to empathise with others and/or (2) their ability to read mental states in others’ eyes than adults with Asperger syndrome (AS). The Empathy Quotient (EQ) and ‘Reading the Mind in the Eyes’ Test (Eyes Test) were compared in 43 adults with AS and 43 adults with HFA. No significant difference was observed on EQ score between groups, while adults with AS performed significantly better on the Eyes Test than those with HFA. This suggests that adults with HFA may need more support, particularly in mentalizing and complex emotion recognition, and raises questions about the existence of subgroups within autism spectrum conditions.

Titre : Increasing Face Mask Wearing in Autistic Individuals Using Behavior Analytic Interventions: A Systematic Review and Meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : Rebekah COWELL, Auteur ; Athanasios VOSTANIS, Auteur ; Peter E. LANGDON, Auteur Article en page(s) : p.4061-4080 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The current review aimed to evaluate the effectiveness of behavior-analytic procedures in increasing face mask-wearing in autistic individuals. This comes following recommended guidance during the COVID-19 pandemic. A systematic review and meta-analysis were completed of peer-reviewed and grey literature. Six databases were searched and seven studies using single-case experimental designs met the eligibility criteria which were then quality appraised. Data were extracted on participant characteristics, study design, independent and dependent variables, fidelity, generalization, maintenance, and social validity outcomes. Both the non-overlap of all pairs and Baseline Corrected TAU were used to estimate effect size. Two studies were rated strong and borderline strong quality and five were rated as adequate or below. All studies showed positive outcomes for mask-wearing, with an average of 0.92 for non-overlap of all pairs and 0.47 for Baseline Corrected Tau effect sizes. The most common and effective procedures for increasing mask-wearing were graded exposure and differential and positive reinforcement. Factors such as mode of delivery, implementer, and setting did not appear to influence study outcomes. Procedures were found to be rated as acceptable by parents and professionals in five of the studies. The existing literature on increasing face mask-wearing in autistic individuals provides promising findings to add to existing literature around increasing tolerance to medical equipment and hygiene practices in autistic populations. However, these findings are based on a small sample size, with six of the studies taking place in the United States with varying study quality.

Titre : Social Media and Cyber-Bullying in Autistic Adults Type de document : Texte imprimé et/ou numérique Auteurs : Paraskevi TRIANTAFYLLOPOULOU, Auteur ; Charlotte CLARK-HUGHES, Auteur ; Peter E. LANGDON, Auteur Article en page(s) : p.4966-4974 Langues : Anglais (eng) Mots-clés : Adult Autism Spectrum Disorder Autistic Disorder Bullying Crime Victims Cyberbullying Humans Internet Social Media Autism Cyber-aggression Cyber-bullying victimisation Social media Index. décimale : PER Périodiques Résumé : Social media can lead to rejection, cyber-bullying victimisation, and cyber-aggression, and these experiences are not fully understood as experienced by autistic adults. To investigate this, 78 autistic adults completed self-report measures of social media use, cyber-bullying victimisation, cyber-aggression, and self-esteem. High levels of social media use were found to be associated with an increased risk of cyber-victimisation; whereas self-esteem was positively correlated with feelings of belonging to an online community and negatively correlated with feelings of being ignored on social network sites and chat rooms. Future studies are needed to further investigate the experience of cyber-bullying victimisation of autistic adults.

This study aimed to assess the reliability and validity of the PCL:SV with autistic adults detained in inpatient psychiatric care. Data were collected from 282 autistic adults at two time points separated by 12-months. Reliability and validity were investigated using omega, regression, receiver operating characteristic curves, and correlational analysis. PCL:SV Total, Factor 1, and Factor 2 had satisfactory to high reliability and construct validity. Higher PCL:SV scores were associated with poorer treatment progress, a longer length of stay, and previous criminal offending. Factor 1 was associated with a forensic history, detention under Part III of the Mental Health Act, and a personality disorder diagnosis, while Factor 2 was also associated with the absence of a forensic history, detention under Part II of the Mental Health Act, but not a personality disorder diagnosis. It was thought that Factor 2 most likely captured data associated with autism and/or intellectual disabilities (e.g., behaviors that challenge). Those with intellectual disabilities were less likely to have convictions, a history of violent offending, or a forensic history. They were also more likely to be detained under Part II of the Mental Health Act, and were more likely to have had a positive transfer 12-months later to a ward with lesser security. The PCL-SV correlated as expected with the HCR-20 and the START. This study provides preliminary evidence to support the use of the PCL:SV with autistic adults, including those with intellectual disabilities, within inpatient psychiatric hospitals.

Titre : Validation of the social communication questionnaire amongst Nigerian adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Glynis H. MURPHY, Auteur ; Peter E. LANGDON, Auteur Article en page(s) : p.66-77 Index. décimale : PER Périodiques Résumé : Abstract Few autism spectrum disorder (ASD) screening tools have been developed and validated in Africa. This study aimed to examine the psychometric properties of the Social Communication Questionnaire (SCQ) when used with Nigerian adolescents. Parents and caregivers of two hundred and five adolescents completed the SCQ Lifetime form while the adolescents were assessed for ASD using the Autism Diagnostic Observation Schedule, 2nd Edition (ADOS-2). Factor structure and convergent and discriminative validity were examined, along with the sensitivity and specificity of the SCQ in identifying participants with an autism spectrum disorder. The confirmatory factor analysis (CFA) was used to examine the factor structure, while logistic regression and Pearson's correlation coefficient were used to examine the validities. The SCQ had good internal consistency, discriminative, and convergent validity. A cut-off score of 10 revealed sensitivity?=?0.81 and specificity?=?0.88 for the identification of autism spectrum disorder. AUC was 0.83, p?0.001, 95% CI [0.77, 0.90]. The results of this study provide evidence to support the retention of the original four factors of the SCQ. The SCQ has good psychometric properties when used with Nigerian adolescents.
