the effect of health belief model-based training on preventive behaviors of hepatitis b in addicts

Background: prevalence of hepatitis b has been significantly increased among injecting drug users (idus) in the recent years. objectives: the purpose of the present study was to investigate the effect of health belief model (hbm)-based training on the preventive behaviors of hepatitis b in addicts. patients and methods: in this quasi-experimental study, 84 eligible substance users were selected and randomly assigned to experimental and control groups. data were gathered using 3 questionnaires: demographics, hbm’s components, and the preventive behavior of hepatitis b. a hbm-based intervention was conducted on the experimental group. the data were analyzed by paired and independent t-tests, analysis of covariance (ancova), and chi-square test using the spss/16 software. results: a significant difference was observed between the means of all hbm’s components and preventive behaviors of hepatitis b of the 2 groups except perceived severity after the intervention (p < 0.05). in the experimental group, the mean difference of the scores before and after the intervention for each of the hbm’s components and the preventive behavior was significant (p < 0.05). conclusions: training based on hbm could have effects on the preventive behaviors of hepatitis “b”. training based on hmb is recommended as a low-cost and effective method.
