Establishing a Scale for Assessing the Social Validity of Skill Building Interventions for Young Children with Autism Spectrum Disorder

摘要

This study evaluated the psychometric properties of the Scale of Treatment Perceptions (STP), a measure of treatment acceptability targeting skill-building interventions for Autism Spectrum Disorder (ASD). This scale utilizes a strength-based approach to intervention assessment, and was established by modifying the Behavior Intervention Rating Scale (Elliott and Von Brock Treuting in J School Psychol 29(1):43-51, 1991. doi: 10.1016/0022-4405(91)90014-I) and the Treatment Evaluation Inventory (Kazdin in J Appl Behav Anal 13(2):259-273, 1980. doi: 10.1901/jaba.1980.13-259) to be appropriate for assessing multiple dimensions of acceptability across skill-building ASD treatments. Overall, the STP demonstrated good psychometric properties: the scale had appropriate internal consistency, demonstrated a stable three-factor structure that was invariant across samples, and discriminated among different skill-building treatments for ASD. This has important implications for dissemination, as perceived acceptability of a treatment relates to treatment utilization and adherence.
