Materials and Methods: This cross-sectional study was carried out on 340 pregnant women in Arak city. After reviewing the related literature, the instrument was designed and its content validity ratio, content validity index, face validity, and exploratory factor analysis were measured. For measuring the reliability of the scales, three methods, including test-retest, internal consistency, and agreement, were used. Data analysis was done using SPSS software.
Results: The reliability of the 61 items was evaluated with impact score of 1.5 and the content validity index of 0.79 and based on exploratory factor analysis were classified into seven categories. The overall reliability measured through Cronbach alpha was 0.84. The reliability of the questionnaire was 0.88, perceived susceptibility was 0.73, severity was 0.70, perceived benefits was 0.75, perceived barriers was 0.71, the cues to action was 0.72, and self-efficacy was 0.76. Kappa coefficients were determined with a high performance for checklists.
Conclusion: This study provided good evidence of the strength factor structure and reliability of Health Belief Model structures about oral health behaviors in the vulnerable group of pregnant women, according to the study of psychometrics process.
