Adaptive behaviors and related factors in children and adolescents with autism spectrum disorder: Report from ELENA cohort.

There are strong individual differences in adaptive behaviors (AB) in autism spectrum disorder (ASD) with conflicting results in literature about specific patterns and related factors. The present study aims to describe AB and identify related factors in terms of clinical and socio-familial characteristics in 875 children and adolescents with ASD in the multiregional ELENA cohort in France. Results showed that AB in children and adolescents with ASD were lower than in typically developing subjects, regardless of age group. AB were associated with clinical (gender, age at diagnosis, IQ, ASD severity, psychiatric comorbidities, motor and language skills, challenging behaviors), interventional (school attendance, special interventions) and familial characteristics (age, educational and socio-economic status of parents, household status, number of siblings). There is a need of interventions focusing on improvement of AB, tailored to children's characteristics.

Anxiety and depression in parents of children with autism spectrum disorder during the first COVID-19 lockdown: Report from the ELENA cohort.

BACKGROUND: The Covid-19 pandemic had a strong impact on mental health in the general population. This study conducted during the first lockdown in France considered parents of children with Autism Spectrum Disorder (ASD) prospectively followed in the ELENA Cohort. OBJECTIVES: We aimed to (1) compare the Anxiety and Depression (AaD) levels during the lockdown between mothers and fathers, (2) compare the parent's AaD between the lockdown and the last ELENA follow-up visit, and (3) identify risk factors for parental AaD during lockdown among socio-demographic and children's clinical characteristics. METHODS: The Hospital Anxiety and Depression Scale (HADS) was used to assess AaD in 134 parent's pairs. Parents also completed the Questionnaire about their living conditions during COVID-19, their child's interventions and perceived changes about their child's behaviors and sleep. Child's ASD severity, intellectual and socio-adaptive skills and parent's socio-demographic characteristics were collected from ELENA follow-up. RESULTS: The parents' AaD levels were lower during the lockdown compared to the last ELENA visit that coincided in 96% with the child's ASD diagnosis. The AaD levels were more pronounced in mothers and significantly associated with the child's challenging behaviors, parents' teleworking and perceived knowledge about COVID-19. The perception of an insufficient knowledge was the only risk factor for mothers' AaD. CONCLUSION: Our findings highlighted the pertinence for an assessment of the mental health of main caregivers of children with ASD, consideration of their gender characteristics, and the importance of providing relevant information during pandemic. Future studies examining the pandemic long-term effects are needed. TRIAL REGISTRATION NUMBER: NCT02625116.

WISC-V Profiles and Their Correlates in Children with Autism Spectrum Disorder without Intellectual Developmental Disorder: Report from the ELENA Cohort.

The intellectual functioning of people with autism spectrum disorder (ASD) without intellectual developmental disorder (IDD) has not been widely studied. However, marked heterogeneity in assessment measures, samples, and results has been an obstacle for the generalization of findings. We aimed to (a) describe WISC-V intellectual functioning in a sample of children with autism spectrum disorder without intellectual developmental disorder, (b) identify WISC-V profiles, and (c) explore whether WISC-V intellectual functioning is related to ASD symptom severity and adaptive skills. Our sample consisted of 121 children from 6 to 16 years of age with ascertained ASD without an intellectual developmental disorder (IDD). The intellectual functioning of the participants was within the average range. Intra-individual analysis showed that children with ASD performed better on visual than auditory working-memory tasks. Moreover, the intellectual functioning of the participants correlated negatively with ASD symptom severity but positively with adaptive communication skills. Overall, we identified six intellectual profiles according to verbal and reasoning skills. These findings highlight the relevance of WISC-V assessment for children with ASD without an IDD to individualize intervention, especially remediation. LAY SUMMARY: This study examined WISC-V intellectual functioning in 121 children with autism spectrum disorder (ASD) without an intellectual developmental disorder (IDD). We found their intellectual functioning to be within the average, as was that of their peers with typical development (TD), and their verbal and reasoning skills were the most discriminant. In addition, the better their intellectual functioning was, the better their adaptive communication skills and the less severe their ASD symptoms. These findings highlight the relevance of WISC-V assessment in ASD to individualize early psychological remediation.
