Behavioral parent training is an evidence-based intervention that reduces child problem behavior. Unfortunately, there are notable disparities in access to and use of evidence-based parenting interventions, including BPT. One way to address the service gap is through technology-based parenting interventions. The purpose of this systematic review is to identify the populations targeted in technology-based parenting interventions, the effectiveness of these interventions, and areas and populations where future research is warranted. A search of three databases yielded 31 articles that met inclusion criteria. We included articles if they (a) were treatment outcome studies using web-based interventions or (b) discussed methodologies or models pertaining to web-based interventions, (c) specified demographic information such as race, ethnicity, and SES, and (d) were published in English or Spanish. We coded 25 treatment outcome studies and six feasibility studies. Technology-based parenting interventions have successfully improved parenting variables such as parent knowledge, behavior, and self-efficacy. Yet the vast majority of these interventions are validated with White American families and lack adaptations that may make them more accessible to underserved populations. As the burgeoning area of technology-based interventions continues to grow, researchers should consider underserved populations and appropriate cultural adaptations that could reduce mental health disparities and increase the scope of evidence-based interventions.
