Modeling factors influencing enrollment in family-focused preventive intervention research.

The reported study tests an extension of a previously supported model of family context and health belief predictors of parental inclination to enroll in preventive interventions. The extended model addresses limitations in the prior investigation; it examines the role of intervention-related beliefs and inclinations on actual enrollment in a skills training intervention research project. Model testing was conducted with a sample of 635 parents of 6th graders who completed a prospective participation factor survey and were recruited for an intervention research project 6 months later. The model fit was strong and all but one of the primary hypothesized effects were supported. Notably, both stated inclination to enroll in an intervention and in the research project had significant positive effects on actual project enrollment occurring 6 months later. Perceived intervention benefits and barriers had significant effects on both types of stated inclination to enroll. Examination of modification indices for the model suggested an additional path linking educational attainment with actual enrollment.
