Abstract: | ABSTRACTIntroduction: Current measures of restrictive and repetitive behavior (RRB) in people with autism focus on severity and intensity and, to some degree, the global interference of the behavior. In this study we developed the Social Impact of Repetitive Behavior Scale (SIRBS) to capture several different contexts in which repetitive behavior is likely to occur and interfere.Methods: SIRBS items were selected through reviewing the RRB literature, participant chart reviews, and consensus among authors, followed by an initial piloting and further refinement of the tool. Caregivers completed the SIRBS a total of 400 times.Results: Subscales showed high internal consistency and good test-retest reliability, moderate concurrent validity, and average to excellent inter-rater reliability.Conclusion: The SIRBS is a psychometrically reliable and valid measure of the social impact of repetitive behavior with children with autism. Additional research is needed to independently validate it and conduct an initial exploratory factor analysis of subscales. |
