Occupational Therapy Outcome Measures in Preschool Children With Autism Spectrum Disorders: A Scoping Review

Abstract

With the rising prevalence of autism spectrum disorder (ASD), early assessment of preschool children is vital for occupational therapists. This scoping review aimed to provide detailed information about outcome measures used in occupational therapy interventions in preschool children with ASD and map the focus of the outcome measures based on the International Classification of Functioning, Disability, and Health (ICF) components. A thorough search from 2000 to 2022 was conducted that employed ICF linking rules to categorize the outcome measures. Seventy-four outcome measures were identified. They predominantly targeted body function and activity/participation, with less emphasis on environmental factors, and none assessed body structure. The most common measures were Vineland Adaptive Behavior Scale (VABS-2), Canadian Occupational Performance Measure (COPM), and Parenting Stress Index–Short Form (PSI-SF). This study offers a diverse array of outcome measures and underscores the potential of the ICF framework in enhancing evaluations, particularly concerning broader environmental components as one of the primary facilitating/hindering factors in the participation of children with ASD.
