With advances in knowledge regarding efficacious evidence-based interventions, there have been significant attempts to culturally adapt, implement, and disseminate parent training interventions broadly, especially across ethnic and cultural groups. We sought to examine the extent to which researchers and developers of evidence-based parent training programs have used cultural adaptation models, tested implementation strategies, and evaluated implementation outcomes when integrating the interventions into routine care by conducting a systematic review of the literature for four evidence-based parent training interventions: Parent-Child Interaction Therapy (PCIT), The Incredible Years (IY), Parent Management Training-Oregon Model (PMTO™), and the Positive Parenting Program (Triple P). A total of 610 articles across the four programs were identified. Of those, only eight documented a rigorous cultural adaptation process, and only two sought to test the effectiveness of implementation strategies by using rigorous research designs. Our findings suggest that there is much work to be done to move parent-training intervention research towards a more rigorous examination of cultural adaptation and implementation practices.
