Sinicization of the Index of Dental Anxiety and Fear Scale and the test of reliability and validity / 中国实用护理杂志

ABSTRACT

Objective:To sinicize the Index of Dental Anxiety and Fear (IDAF-4C +), and to test its reliability and validity. Methods:According to the Brislin translation model, the literal translation, back translation, cultural adjustment and pre-investigation of the scale were carried out to form the Chinese version of the IDAF-4C + Scale, and the convenience sampling method was used to investigate the outpatients of the Affiliated Stomatological Hospital of Nanchang University from October 2021 to January 2022 to verify the reliability and validity of the scale. Results:The Chinese version of the IDAF-4C + Scale consisted of three modules (core anxiety module, fear module and stress module), with a total of 23 items, of which the core anxiety module included cognitive, physiological, behavioral and emotional dimensions. The content validity index of each item was 0.8-1.0, and the content validity index of the total scale was 0.913; the construct validity was 0.903, and a common factor was extracted by exploratory factor analysis of anxiety module. The contribution rate of cumulative variance was 72.037%. The results of confirmatory factor analysis showed that the model fitted well and all the adaptation indexes were up to the standard. Using the Modified Dental Anxiety Scale (MDAS) as the criterion, the correlation coefficient between IDAF-4C module and MDAS was 0.66, the Cronbach α coefficient of the scale was 0.913, and the test-retest reliability was 0.923. Conclusions:The Chinese version of the IDAF-4C + Scale has good reliability and validity and can be used as a tool to measure and evaluate the level of dental anxiety and fear in oral patients.
