Background and Objectives: The results of recent studies suggest that model-based health education programs are more effective in changing health behaviors. Interventional programs based on health education theories can be used to explain individual and psychological behavioral determinants in order to reduce the risk of HIV/AIDS. This study was conducted with the aim of psychometric analysis of an HIV scale based on model, population and culture of Iran.
Methods: We used qualitative and quantitative methods during August 2015 to December 2017. The items were generated based on a literature review and interviews with an expert panel. After providing a primary list of the instrument items, we used content and face validity. The first step of the study was done in a sample of medical and non-medical college and high school student from Zanjan. The exploratory factor analysis, internal consistency reliability, and test-retest reliability of the scale were measured.
Results: Fifty-eight items were generated from interviews with experts and review of the literature. After measuring the face and content validity, the items decreased to 53 items. The exploratory factor analysis discovered five factors (perceived susceptibility, severity, benefits, barriers, and self-efficacy), including 30 items for high school students and 31 for university students, that predictive more than 58% of the observed variance. The Cronbach’s alpha coefficient for the sub-scales ranged from 0.80 to 0.86, and the ICC was above 0.86.
Conclusion: The results showed that the HBM was a valid and reliable tool for measuring the HIV/AIDS beliefs and could be used in future investigations.
