Methods: A sample of 365 low-income, rural parents participated in the study. The majority of the sample was female (80%) and the average age of participants was 39 years. The sample was exceptionally racially diverse: 42% African American, 39% American Indian, 9% Hispanic, 6% White, and 4% “other.” Five subscales from the McMaster Family Assessment Device (i.e., problem solving, family roles, affective involvement, behavior control, and general family functioning) were used to measure family processes. In addition, parenting measures (i.e., parenting sense of competence, parenting self-efficacy, and parent-adolescent conflict) and adolescent behavior measures (i.e., violent behavior and externalizing behavior) were collected. Individual growth models and difference-in-difference regression models were estimated to evaluate the impact of the PW program between pre-test, post-test, and 6 month follow-up.
Results: Findings showed statistically significant improvements between pretest, posttest, and 6 month follow-up for family problem solving (ES = .24), family roles (ES = .19), parenting self-efficacy (ES = .19), parent-child conflict (ES = -0.30), adolescent violent behavior (ES = -0.22), and adolescent externalizing symptoms (ES = -0.27). Results indicated few differences by treatment format.
Conclusions/Implications: The current study makes an important contribution to extant literature on PW by examining longer-term program effects on family, parenting, and adolescent outcomes. The maintenance of program effects across delivery formats has not been previously studied. Results have the potential to inform practice decisions regarding the most effective PW format based on specific outcomes of interest.
