An Extended Theory of Planned Behavior for Parent-for-Child Health Behaviors : A Meta-Analysis

OBJECTIVE: To conduct a meta-analysis of studies examining the determinants of behaviors performed by parents to promote the health of their child, termed "parent-for-child health behaviors," based on an extended theory of planned behavior. Specifically, the study aimed to meta-analyze correlations among theory of planned behavior constructs, planning, and past behavior, and use them to test theory predictions and effects of salient moderators. METHOD: A systematic search identified 46 studies that provided correlations between at least one theory construct and intention or behavior for parent-for-child behaviors. Theory predictions were tested using meta-analytic structural equation modeling. Studies were also coded for candidate moderators of model effects: child age, sample type, time lag between measures of theory constructs and parent-for-child health behavior, study quality, and behavior type, and the proposed model was estimated at each level of the moderator. RESULTS: Results supported theory predictions with attitudes, subjective norms, and perceived behavioral control predicting parent-for-child health behavior participation mediated by intention. Perceived behavioral control and planning also directly predicted behavior, and planning partially mediated effects of intention on behavior. Model effects held when controlling for past behavior, supporting the sufficiency of the theory in this behavioral domain. Few moderator effects were found on relations between theory constructs. CONCLUSION: Findings identified the social cognition determinants of parent-for-child health behaviors, and highlight the potential processes by which they relate to behavior. The current model signposts potentially modifiable targets for behavioral interventions aimed at fostering parental participation in behaviors that promote the health of their children.
