Advances in Health and Behavior

Numerous studies have demonstrated that improving factors like family and social support, subjective norms, and attitudes—key elements of the BASNEF model—can greatly influence individuals’ health behaviors. This study evaluated whether an educational intervention based on the BASNEF model improves university students’ quality of life. It used a quasi-experimental design with 60 participants in each of the intervention and control groups. Data were collected using three questionnaires—demographics, BASNEF constructs, and quality of life—and analyzed in SPSS. In the intervention group, most dimensions of quality of life improved from pre- to post-intervention, except vitality and emotional role functioning. Significant changes were also seen in intention, subjective norms, attitude, and enabling factors. Notably, enabling factors and attitude emerged as the strongest predictors of quality of life, suggesting that future health programs should prioritize these elements. Overall, health educators and healthcare professionals can deploy the BASNEF model as a practical, cost-effective framework for modifying lifestyle behaviors and promoting positive health-related quality of life outcomes through educational interventions.
