Adaptive behavior in autism: Minimal clinically important differences on the Vineland‐II

Adaptive behavior in autism: Minimal clinically important differences on the Vineland‐II IntroductionThe diagnostic criteria for Autism Spectrum Disorder (ASD) include clinically significant, functional impairments in social communication and social reciprocity, and the presence of restricted or repetitive behavior and sensory anomalies (DSM‐5; APA, 2013), but ASD is also associated with broader impairments in adaptive behaviors that support everyday functioning [Kanne et al., ]. These adaptive behavior problems span multiple domains including socialization, communication, and daily living skills, and are not fully accounted for by differences in cognitive ability [Charman et al., ; Klin et al., ]. These impairments predict real‐world outcomes in ASD, including educational attainment and the likelihood of independent living [de Bildt, Sytema, Kraijer, Sparrow, & Minderaa, ; Farley et al., ]. Adaptive behavior impairments in ASD are also associated with both the number of support services received, and the service needs that will go unmet [Taylor & Henninger, ]. Thus, adaptive behavior is a key target for interventions directed at individual or societal outcomes in ASD [e.g., Veenstra‐VanderWeele et al., ].It is not currently possible to fully evaluate the efficacy of interventions directed at adaptive behavior. This is because efficacy claims require a demonstration of not only statistical significance, but also clinical meaningfulness [Coon & Cappelleri, ; http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Autism Research Wiley

Abstract

IntroductionThe diagnostic criteria for Autism Spectrum Disorder (ASD) include clinically significant, functional impairments in social communication and social reciprocity, and the presence of restricted or repetitive behavior and sensory anomalies (DSM‐5; APA, 2013), but ASD is also associated with broader impairments in adaptive behaviors that support everyday functioning [Kanne et al., ]. These adaptive behavior problems span multiple domains including socialization, communication, and daily living skills, and are not fully accounted for by differences in cognitive ability [Charman et al., ; Klin et al., ]. These impairments predict real‐world outcomes in ASD, including educational attainment and the likelihood of independent living [de Bildt, Sytema, Kraijer, Sparrow, & Minderaa, ; Farley et al., ]. Adaptive behavior impairments in ASD are also associated with both the number of support services received, and the service needs that will go unmet [Taylor & Henninger, ]. Thus, adaptive behavior is a key target for interventions directed at individual or societal outcomes in ASD [e.g., Veenstra‐VanderWeele et al., ].It is not currently possible to fully evaluate the efficacy of interventions directed at adaptive behavior. This is because efficacy claims require a demonstration of not only statistical significance, but also clinical meaningfulness [Coon & Cappelleri, ;
