Purpose: To review the evidence regarding the effectiveness of Pivotal Response Treatment (PRT) as a treatment for Autism Spectrum Disorder (ASD). Methods: This review employed the systematic review process developed by the American Academy for Cerebral Palsy and Developmental Medicine (AACPDM). A comprehensive search of eight databases was performed. Studies were included if: 1) participants had a primary diagnosis of ASD; 2) PRT was the primary intervention; and 3) participants (receiving treatment) were under 18 years of age. Articles which focused solely on training techniques and did not report on relevant behavioural changes were excluded. Results/Discussion: Twenty studies were included in this review. Many studies demonstrated a positive trend in outcomes, clearly defined they independent and dependent variables, reported inter- and/or intra-rater reliability, and provided sufficient details for clinical replicability. However, several weaknesses were identified in the majority of studies reviewed, including but not limited to: 1) highly variable intervention conditions and independent variables, making comparison across studies difficult; 2) lack of sufficient statistical analysis; 3) lack of standardized assessments; and 4) possible bias with regards to participant selection. Conclusions: Further research is needed on the effectiveness of PRT. Studies with larger sample sizes, greater adherence to rigorous methodology, and use of standardized assessments are required.
