Efficacy of a Parent-Implemented Pivotal Response Treatment for Children with Autism Spectrum Disorder.

PURPOSE

Pivotal response treatment (PRT) is a well-established intervention addressing core symptoms of autism spectrum disorder (ASD), with parent involvement as a key component. The current study aimed to examine the effects of PRT parent training on parent fidelity and provide descriptive analyses of parent-child interactions before and after parent training. It also probed parental acceptance and satisfaction with the program.

METHODS

A concurrent multiple baseline design across participants was used to evaluate the effectiveness of the parent training program. Four parents (range 32-47 years old) and their children with ASD participated in the study. The intervention comprised 12 one-on-one parent training sessions over six consecutive weeks. The visual analysis and effect size calculation (Tau-U) were used to evaluate functional relationship between independent and dependent variables. The descriptive analysis was used to analyze parent-child interaction data.

RESULTS

The findings reveal that all parents learned and maintained PRT with a high level of fidelity, they also enhanced awareness to create more opportunities for interactions during free play, and the parents were very satisfied with the program. The results also indicate that the six-week parent training program is effective in teaching parents to implement PRT with their children.

CONCLUSION

These results suggest that the parent training program may be a promising treatment model that is effective, efficient, and cost-effective. Implications for future research and practice are then discussed.
