Abstract

Abstract: The purpose of this study was to investigate the effects of combined risperidone (RIS) and pivotal response treatment (PRT) on children with autism spectrum disorder (ASD). A total of 34 children diagnosed with ASD according to the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-V) (mean age of 12.36 years) were randomly assigned to either of two groups; the first group (n = 17) received combined PRT-RIS while the second group (n = 17) received RIS only. Behavioral problems were evaluated with the Aberrant Behavior Checklist (ABC), whereas global improvement (GI) was measured with the Clinical Global Impressions (CGI). Assessment of ABC was performed before intervention, after intervention (12 weeks), and following 3 months of the intervention (follow-up). Total ABC scores were seen to decrease in both groups after 3 months, as compared with the scores prior to the interventions. Also, in both groups, mean scores of behavioral problems after the intervention were not significantly different from those prior to the intervention, in all subscales but the inappropriate speech (p < 0.001). However, both groups showed significant differences in mean scores of ABC subscales in both of the post-intervention evaluation stages. It was concluded that the combination of behavioral and drug interventions can further improve behavioral problems, ultimately improving patient's communication and social skills.
