Abstract

Purpose: Anxiety of dentist and dental treatment are quite common problem in general population. Cognitive factors, such as negative thinking, beliefs and expectations about dental treatment are important moderators to be associated with dental anxiety. The aim of this study was to assess the reliability, validity and psychometric characteristics of the Turkish translation of The Dental Cognition Questionnaire (DCQ) that assess the cognitive factors related to dental anxiety Material and Methods: In this study, 177 randomly selected medical students of the University of Istanbul were included. The Dental Cognition Questionnaire, The State Trait Anxiety Inventory (STAI-Trait), The Modified Dental Anxiety Scale (MDAS) were administered to all the participants. The general information form was used to obtain sociodemographic data. All participants again completed the scale after two weeks for test-retest. Cronbach’s alpha, Pearson correlation coefficient and t-test methods were conducted, percentage, mean and standard deviation values were calculated. Results: The mean DCQ-F scores were 11, 45± 7, 27; the mean DCQ-B scores were 52, 51± 30,21. No significant difference was found between women and men groups in terms of the means DCQ-F and DCQ-B (p>0,05). There were significant correlation (Pearson) between DCQ-F and STAI- Trait (p 0,05). Internal consistency coefficient was calculated for DCQ-F as 0,98 and for DCQ-B as 0,88. The mean item-total correlation for the DCQ was 0.85 (Range r=0.63; p<0.001-item 7 to r=0.81; p<0.001-item 21). The test-retest reliability of the DCQ was found to be r=0,76 (p<0,0001).Conclusion: The results of the present study indicate that the Turkish version of DCQ is a valid and reliable scale for research conducted in our country.
