The aim of this study was to investigate the factor structure of the 15-item Dental Beliefs Survey (DBS) in a population of dental phobic patients (n=362). Exploratory (EFA) and confirmatory (CFA) factor analyses were used. The EFA indicated three factors: 'communication', 'trust', and 'fear of negative information'. However, the EFA further suggested a general factor with all 15 items. By using the CFA, five factors were found based on the EFA solution and the original DBS dimensions. A general factor, 'social interaction distress in dental treatment', and four more narrow dimensions, 'communication', 'trust', 'fear of negative information' (originally labelled 'belittlement'), and 'lack of control', was the most adequate result with regard to theoretical and statistical properties. However, some items in the factors were partly different from the original version of the DBS. In conclusion, the DBS attempts to measure a complex phenomenon with regard to patients' perceptions and attitudes to dental care. This study has revealed psychometric properties of the DBS in a population of dental phobic patients. The important finding was a general dimension, which suggests the use of DBS as an overall measure of dental beliefs. However, more research is needed in epidemiological and clinical studies with non-phobic individuals.
本研究旨在调查牙科恐惧症患者群体（n = 362）中15项牙科信念调查问卷（DBS）的因子结构。采用了探索性因子分析（EFA）和验证性因子分析（CFA）。探索性因子分析表明存在三个因子：“沟通”、“信任”和“对负面信息的恐惧”。然而，探索性因子分析还进一步提示了一个包含所有15个条目的一般因子。通过验证性因子分析，基于探索性因子分析的结果和原始DBS维度发现了五个因子。一个一般因子“牙科治疗中的社会互动困扰”，以及四个更具体的维度“沟通”、“信任”、“对负面信息的恐惧”（原标记为“轻视”）和“缺乏控制”，在理论和统计特性方面是最合适的结果。然而，这些因子中的一些条目与DBS的原始版本部分不同。总之，DBS试图测量患者对牙科护理的认知和态度这一复杂现象。本研究揭示了DBS在牙科恐惧症患者群体中的心理测量特性。重要发现是一个一般维度，这表明可将DBS用作牙科信念的总体测量指标。然而，在针对非恐惧症个体的流行病学和临床研究中还需要更多研究。
