Validity and Reliability of the Vietnamese Version of the Dental Fear Survey.
Article in International dental journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThe 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.
methodsThe 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 (r
resultsThe 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 r
conclusionsDFS 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.
