Promoting drug abuse preventive behaviors in adolescent students based on the health belief model.

Background Nowadays, drug abuse is one of the most important health problems that can affect the quality of life of people in mental, psychological, physical, and social dimensions. Theory-based education can help the adolescents to promote their drug abuse preventive behaviors. Objectives The aim of this study was to determine the effectiveness of education based on the health belief model (HBM) on drug abuse preventive behaviors in adolescent students. Methods This study was an interventional quasi-experimental study with a pre-test/post-test design conducted in two high schools in the southeast of Iran. A two-step cluster sampling method was used and 120 students were randomly selected and categorized into the control (n = 60) and intervention (n = 60) groups. The intervention group participated in an education program based on the HBM in four 75-min sessions. Data were collected using demographic and drug abuse preventive behavior questionnaires based on the HBM. Results In the pre-test stage, the mean scores of drug abuse preventive behaviors and its dimensions were not significantly different between the intervention and control groups (t = -2.597 p = 0.641). In the post-test stage, the mean scores of the intervention and control groups were significantly different; the drug abuse preventive behaviors and its dimensions improved in the intervention group (t = 14.57, p < 0.001). Conclusion The findings showed that education based on the HBM had a significant effect on drug abuse preventive behaviors and its dimensions. Therefore, educational packages based on the HBM are recommended to improve these behaviors in adolescents.
