牙科畏惧调查（DFS）量表中文版的研制与评价

 【目的】牙科畏惧调查（DFS）量表中文版的研制及其信度和效度等心理测量学性质检验。【方法】按照心理测量学中量表的跨文化适应程序对DFS量表英文版进行翻译、回译和文化调试建立DFS中文版；使用DFS中文版对抽取的18岁以上439成人进行牙科畏惧症调查，检验量表的信度、效度等心理测量学性质，并对其畏惧程度以自评方式分类。【结果】DFS量表中文版的重测信度为0．85，内部一致性Cronbaeh’s α系数和分半系数分别为0．94和0．87，条目与量表的相关系数在0．45—0．87之间；因子分析共选出4个公因子，累计贡献率达71．32％。涵盖了量表治疗逃避心理和预期焦虑、躯体焦虑和治疗刺激焦虑三个方面，4个公因子的分布与理论结构假设相符；不同畏惧水平人群的DFS量表得分有明显差异（P〈0．001）。【结论】DFS量表中文版具有良好的信度、效度。其良好的心理测量学性质为该量表在我国运用提供了一定的理论依据，为今后成人牙科畏惧症的研究提供了一个较好的评价工具。

Development and Evaluation of Chinese Version of Dental Fear Survey (DFS)

Objective] To develop the Chinese version of Dental Fear Survey (DFS) and test the reliability and validity of DFS. Methods] The English version of DFS was translated and back-translated, as well as cross-cultural adapted by the method of psychometrics to develop the Chinese version of DFS. A total of 439 adult people aged 18 and over were randomly selected and surveyed by the Chinese version of DFS. Formal psychometric properties were tested according to the survey. Levels of dental fear were also rated by themselves. Results] The test-retest reliability coefficient of DFS was 0.85. The internal consistency coefficient was 0.94. The split-half reliability coefficient was 0.87. The item-scale correlation ranged from 0.45 to 0.87. The factor analysis of DFS resulted in four factors which accounted for 71.32% of the scale's total variances. The four factors contained three domains of DFS, which were avoidance of dental treatment and anticipated anxiety, somatic symptoms of anxiety and anxiety caused by dental stimuli. The DFS scores were showed significant difference in subjects with different self-rated dental fear (P< 0.001). Conclusions] The Chinese version of DFS demonstrated good reliability and validity. Sufficient discriminative and evaluative psychometric properties of the Chinese version of DFS made the instrument suitable for study on dental fear for Chinese adult populations, and provided theoretical evidence for its future use.
