From intentions to actions : self-efficacy and self-regulation in the adoption and maintenance of health behaviors in Costa Ricans and Germans

Abstract

This longitudinal study examined the mediator model postulated in the Health Action Process Approach (HAPA). Specifically, the study emphasizes the impact of self-efficacy beliefs and self-regulation processes on the adoption and maintenance of health-related behaviors (i.e., healthy diet, and physical exercise). Data were gathered at two measurement points in time, 6-months apart, from a longitudinal sample of about 500 Costa Ricans. Results supported assumptions and offer new insights regarding the prediction of health-related intentions (motivation phase) and health-related actions (volitional phase). Findings are compared with previous results and discussed in light of cross-cultural validation and implications for health promotion.
