Abstract

Dental anxiety has been reported to be of global public health concern. In Nigeria, not much work has been documented on dental anxiety. The objectives of this study were to estimate the prevalence of dental anxiety and determine the reliability and validity of the Modified Dental Anxiety Scale (MDAS) in screening for dental anxiety among Nigerian adult dental patients. One hundred and ninety adult participants were invited to complete a sociodemographic questionnaire, Modified Dental Anxiety Scale and Hamilton Anxiety Rating Scale in order to determine the prevalence, internal consistency and concurrent validity of the Modified Dental Anxiety Scale. The mean score of the MDAS was 11.0 (SD = 6.1) and the scores ranged from 5-25. Of the total 190 participants, 60 (48.6%) scored above the cut-off score of 11. The internal consistency of the MDAS was 0.90 (95% CI = 0.94-0.97). The MDAS correlated well with HARS; the concurrent validity coefficient of 0.58 was obtained. (r = 0.90, p<0-0001). At normative cut-off score of 11.0, MDAS sensitivity was 0.8 and specificity 0.85. These psychometric findings showed that the MDAS has good internal consistency as well as good concurrent validity coefficient. Because of its reliability, validity, brevity and ease of administration, the MDAS is considered a useful instrument for measuring dental anxiety among Nigerians.

尼日利亚人群牙科焦虑的患病率及修正牙科焦虑量表的验证

据报道，牙齿焦虑已成为全球公共卫生关注的问题。在尼日利亚，没有太多关于牙齿焦虑的工作记录。本研究的目的是估计牙科焦虑的患病率，并确定修正牙科焦虑量表(MDAS)在筛查尼日利亚成年牙科患者牙科焦虑方面的可靠性和有效性。采用社会人口学问卷、修正牙科焦虑量表和汉密尔顿焦虑评定量表对190名成人进行问卷调查，以确定修正牙科焦虑量表的流行程度、内部一致性和并发效度。MDAS平均评分为11.0 (SD = 6.1)，评分范围为5 ~ 25分。在190名参与者中，60人(48.6%)的得分超过了11分的分界点。MDAS的内部一致性为0.90 (95% CI = 0.94 ~ 0.97)。MDAS与HARS具有良好的相关性;并发效度系数为0.58。(r = 0.90, p<0-0001)。在标准临界值11.0时，MDAS的敏感性为0.8，特异性为0.85。这些心理测量结果表明，MDAS具有良好的内部一致性和良好的并发效度系数。由于其可靠性、有效性、简便性和易于管理，MDAS被认为是衡量尼日利亚人牙齿焦虑的有用工具。关键词:患病率，信度，效度，修正牙科焦虑量表尼日利亚医生第62卷第5-6期，2012
