Methods: This longitudinal study followed two cohorts of parents over two years. Randomized at the school-level, parents and youth in nine schools were assigned into one of three conditions: (1) control condition (C), (2) youth-only condition, receiving only kiR, (Y), and (3) parent + youth condition, receiving FPNG and kiR, (PY). Parents of 7th grade youth (N=393, 82.8% mothers, M = 38.5 years old, 34.7% some high school/no diploma) completed self-report questionnaires at baseline and immediately following the intervention. A measurement model for positive parenting was evaluated using confirmatory factor analysis (CFA), followed by structural equation modeling (SEM) to estimate the effects of the intervention on positive parenting.
Findings: Using the four indicator variables for positive parenting (i.e., praise, affection, reward, privilege), the CFA model fit indices were acceptable: χ2 (1) = .81, p=.37; RMSEA=.00; CFI=1.00; TLI=1.01. Structural equation models confirmed that PY parents reported greater levels of positive parenting (β = .13, p < .05) at the follow-up compared to Y parents, controlling for positive parenting at baseline. C parents were not significantly different than Y parents at follow-up (β = .07, p > .05,). The SEM model had good fit: χ2(27) = 39.51, p=.06; RMSEA = .03; CFI=.98; TLI=.96.
Conclusion: The results indicate that parenting interventions designed to take into account the environment of the families, including culture of origin and its cultural assets, can lead to a significant strengthening of positive parenting practices. The current findings provide a strong validation for culturally specific family-centered interventions that can enhance and complement school-based substance abuse prevention efforts with Mexican American youth.
