Abstract

The aim of this study is to create a Turkish version of the Revised Dental Beliefs Survey (DBS-R) and describe its psychometric properties. The participants were 420 general dental patients. The results of the exploratory factor analysis revealed that the DBS-R consisted of three factors consisting of 22 items. Confirmatory factor analysis results showed that the 22-item three-factor version fit the data better than the original 28-item English language four-factor structure model proposed in Odontol Scand (2004;62:21). The internal reliability of the Turkish version of the DBS-R was Cronbach alpha of 0.88. The correlation between the Turkish version of the DBS-R and the Modified Dental Anxiety Scale (MDAS) was 0.29. Scores on the 22-item version were higher for anxious participants (MDAS > or = 15) than those determined to be not anxious [59.4 +/- 15.5 vs. 51.1 +/- 17.2 (t = -4.38, P < 0.0001)]. In conclusion, a 22-item modified version of the DBS-R in Turkish appears reliable and valid.
