Abstract

Purpose

Access to intervention is a barrier for children with autism. As parent-mediated interventions have emerged to address this need, understanding implementation components contributing to child gains is critically important. Existing literature documents relationships between parent treatment adherence and child progress; however, less is understood about components, such as frequency of learning opportunities, which could also affect child outcomes.

Methods

This study is a secondary analysis of data from a randomized controlled trial evaluating Pivotal Response Treatment group parent training (PRTG) compared to psychoeducation. Linear regression and mediational models were employed to identify potential predictors and mediators of outcome.

Results

PRTG produced large increases in adherence and learning opportunities. In general, greater frequency of learning opportunities and adherence predicted better child outcomes. The best-fitting cross-sectional mediational models indicated at least partial mediational effects, whereby increased learning opportunities mediated the relationship between greater adherence and improved child outcomes.

Conclusions

This study provides preliminary evidence of how early gains in adherence may support parents to provide more frequent learning opportunities, which, in turn, yield positive effects on child social communication. Future large-scale research, with greater granularity of measurement, is needed to further understand the temporal relationships between these variables.
