Social Skills Interventions for Adolescents with Level 1 Autism Spectrum Disorder: A Systematic Review with Meta-Analysis of Randomized Controlled Trials.

Objective: Evidence on the efficacy of social skills training for adolescents with Level 1 Autism Spectrum Disorder (ASD) is unclear. Method: We searched Pubmed, Scopus, and Web of Science until July 27th, 2023, for randomized controlled trials (RCTs) of social skills training for pre-adolescents and adolescents (aged 9-18) with Level 1 ASD. We then pooled data on efficacy from individual RCTs by conducting multivariate mixed-effects meta-analyses in R. We estimated possible bias in the retained RCTs using the RoB2 tool. Results: We retained 36 RCTs (encompassing 2796 participants), including 18 RCTs comparing an experimental treatment to a waiting list, and 18 RCTs comparing it to standard care/control treatment. Meta-analyses showed that experimental treatments were significantly more efficacious than waiting list or standard care/ control treatments in improving social skills (SMD = 0.3745; 95%CI = [0.2396; 0.5093]), as well as reducing behavioral symptoms (0.3154;0.1783, 0.4525) and anxious/depressive symptoms (0.2780; 0.0432, 0.5128). However, for some outcomes there was significant heterogeneity across studies and evidence of publication bias. Subgroup analyses and meta-regressions did not identify any specific clinical or demographic factors as significant predictors of outcome. The most common risk of bias across studies was related to deviations from intended interventions and measurement of the outcomes. Conclusions: At the group level, social skills training for adolescents with Level 1 ASD is efficacious, with small-to-moderate effect size. Future research should focus on personalized medicine approaches, aimed at tailoring interventions to specific characteristics of adolescents with Level 1 ASD.

Early Sensory Profile in Autism Spectrum Disorders Predicts Emotional and Behavioral Issues.

Background: Abnormal sensory reactivity is considered one of the diagnostic criteria for autism spectrum disorders (ASD) and has been associated with autism severity, poorer functional outcomes, and behavioral difficulties across the lifespan. Its early characterization could provide valuable insights into the processes favoring the instantiation of maladaptive behaviors. Objectives: The present study has two aims: (1) to describe the sensory profile of preschool children with ASD compared with an age-matched population of children with a diagnosis of language disorder (DLD) and typically developing (TD) control peers; (2) to explore within each group whether the sensory alterations play a predictive role in the instantiation of emotional and behavioral issues. Methods: The parents of 42 ASD, 18 DLD, and 56 TD filled out the Sensory Processing Measure­Preschool (SPM-P). To gather information on competencies, behaviors, and emotional problems of children, the Child Behavior Checklist 1½-5 (CBCL 1½-5) was also administered. Results: On the SPM-P, ASD and DLD samples generally had scores more compromised than control peers. The contrast between ASD and DLD was reflected in a higher (and highly significant) impairment on the social participation and hearing subscales, suggesting a greater sensitivity and a possible specificity of these scores for ASD. More importantly, linear regression analyses revealed a strong and predictive association for ASD children with SPM total scores explaining more than 50% of the variance of the CBCL 1½-5 total scores (p < 0.001). Conclusions: Our findings reinforce the need to detect the abnormal sensory profiles of ASD already at an early stage and during clinical evaluations. Due to the impact on the emotional and behavioral manifestations, such a procedure has significant clinical and social implications, potentially guiding the development of new interventions relying on multisensory strategies.
