Psychometric Properties of the Turkish Oral Health Behavior Questionnaire for Adolescents Based on the Health Belief Model

Objective: To identify oral and dental health behaviors as critical life skills for adolescents. This study examined the Turkish psychometric properties of the “Health Belief Model-Based Oral Health Behavior Questionnaire for Adolescents” (OHBQAHBM). Methods: This was a methodological study. The study sample consisted of 335 adolescents aged 13–18 years. The Sociodemographic Information Form and OHBQAHBM were used to gather data. The data analysis and evaluation were performed using factor analysis, Cronbach’s alpha, and item-total score correlation. Results: Thirty-five items were recorded on the main scale, and the other items were recorded on six subscales. The six subscales had a variance of 50.4%. The Turkish Cronbach’s alpha coefficient was 0.880. Because of confirmatory factor analysis, the model fit index results were recorded as follows: 0.048 as the RMSEA, 0.861 as the goodness-of-fit index, and 0.924 as the comparative fit index. Conclusions: The measurement tool was valid and reliable for evaluating adolescents’ oral and dental health behaviors based on their health belief model.
