Recent literature underscores the need for studies of family-based preventive interventions oriented toward public health objectives. This article illustrates a program evaluation approach for the study of family intervention outcomes in general populations. Thirty-three rural schools were randomly assigned to one of three conditions: the Preparing for the Drug Free Years Program (PDFY), the Iowa Strengthening Families Program (ISFP), and a minimal-contact control group. Self-report and observational data collected from 523 families were used to develop measurement models of three latent parenting constructs that included measurement method effects. Analyses were conducted to ensure initial and attrition-related group equivalencies and to assess school effects. Structural equation models of the hypothesized sequence of direct and indirect effects for both PDFY and ISFP were then fit to the data. All hypothesized effects were significant for both interventions. The discussion addresses the potential public health benefits of evaluation research on universal preventive interventions.
