Abstract (768 Views)
Aims: Negative views of dentists contribute to dental anxiety and reduced visits, worsening oral health. In Iran, where oral diseases are common and preventive care is low, understanding dental beliefs is essential. This study evaluated the psychometric properties of the Persian Dental Beliefs Survey-Revised to support dental health awareness and behavior change.
Instrument & Methods: This cross-sectional psychometric study was conducted in 2024, involving 400 students at Saveh University of Medical Sciences, selected via convenience sampling. The original Dental Beliefs Survey-Revised was translated from English to Persian using the forward-backward translation method. Face and content validity were confirmed through qualitative assessment. Structural validity was examined using exploratory and confirmatory factor analyses. Internal consistency and reliability were measured by Cronbach’s alpha, McDonald’s omega, and Composite Reliability. Convergent and discriminant validity were assessed through average variance extracted, maximum shared variance, and Fornell-Larcker criteria. Statistical analyses were conducted using SPSS 21 and AMOS 18.
Findings: The Persian Dental Beliefs Survey-Revised identified four factors (ethics (8 items), communication (6 items), control (4 items), and trust (6 items)) explaining 56.8% of the total variance. Goodness-of-fit indices from confirmatory factor analysis confirmed a satisfactory model fit. All reliability indices were strong, and both convergent and discriminant validity were found to be acceptable.
Conclusion: The Persian version of the DBS-R demonstrates strong psychometric properties and is suitable for use in academic, clinical, and public health research within Persian-speaking populations.
