| description | ABSTRACT: Objectives: The use of questionnaires to assess patients’ dental fear is critical to dental research and practice. As one of the most well-established tools in this field, the Dental Fear Survey (DFS) was translated into Vietnamese (V-DFS) and employed in previous studies. However, its validity and reliability have not been reported. This study aimed to determine the validity and reliability of V-DFS in adults. Methods: The DFS was translated to Vietnamese in accordance with the “Guideline for the Process of Cross-cultural Adaptation of Self-reported Measures” to create the V-DFS. Next, 414 students at Pham Ngoc Thach University of Medicine completed the V-DFS to examine its validity and reliability. The factorial validity of V-DFS was assessed using exploratory factor analysis (EFA) and structural equation modeling (SEM). The internal consistency and test-retest reliability of the V-DFS were assessed using Cronbach's alpha (α), intraclass correlation coefficient (ICC), and Spearman's rank-order correlation coefficient (rs). Results: The rotated component matrix of the EFA revealed 3 factors: specific stimuli, anticipatory fear and avoidance, and physiologic arousal. The statistical indices of the best-fitting V-DFS model in SEM analysis satisfied the cutoff values. Cronbach's α ranged from .82 to .94 for the 3 factors. The ICC and rs of the whole questionnaire were .86 and .86, respectively. Conclusions: DFS was successfully translated into Vietnamese with good validity and reliability. Further research should be conducted to examine its validity in various populations and to improve its characteristics. |
