Child maltreatment is an adverse childhood experience associated with reductions in child well-being. This study examines whether an evidence-based parenting intervention delivered to families served by the child welfare system (CWS) affects pediatric health-related quality of life (HRQoL).


This study is a randomized controlled trial of Pathways Triple P (PTP) delivered to families with open child welfare cases for child physical abuse or neglect (N = 119). Children were 5 to 11 years old and remained in the home after the investigation. The primary outcome measure for this study was the Pediatric Quality of Life Inventory (PedsQL) 4.0, which measures HRQoL across 4 subdomains: physical functioning, emotional functioning, social functioning, and school functioning. Child- and parent-reported PedsQL 4.0 was assessed at baseline and post-test after the 14-week intervention.


Controlling for other factors, children in families randomly assigned to the PTP condition had a significant improvement in overall HRQoL after the intervention compared with families receiving usual services (βchild-report = 6.08, SE = 2.77, p = 0.03; βparent-report = 3.83, SE = 1.88, p = 0.04). Subdomain effect sizes differed when considering children's self-report or parents' proxy report. Children's self-report yielded the largest improvement in emotional functioning, whereas social functioning had the largest gain based on parents' proxy report.


The PTP parenting intervention was associated with higher pediatric HRQoL as reported by both the child and parent. This intervention holds promise to improve child well-being when implemented in the CWS.
