Cross-Cultural Adaptation of Kannada Version of Modified Dental Anxiety Scale Among an Adult Indian Population.

BACKGROUND

Dental anxiety is one of the most common barriers in seeking dental care. In order to overcome this barrier dentist need to screen patients to successfully help in treatment. A scale is thus needed to measure dental anxiety which is socially & culturally acceptable.

AIM

This study aimed to assess the Cross cultural adaptation and validity of the Kannada translation of the Modified Dental Anxiety Scale (MDAS-K).

MATERIALS AND METHODS

A test-retest was conducted on 30 patients visiting a dental institution to assess the reliability of MDAS- K. A cross-sectional survey of 301 patients was conducted in different departments at a dental institution to test the psychometric properties of MDAS-K. The assessment tool consisted of a proforma containing socio-demographic, non socio- demographic variables, MDAS-K and Visual analogue scale (VAS).

STATISTICAL ANALYSIS

Reliability was assessed using Cronbach's alpha, inter-item Spearman's correlation. Independent t-test, ANOVA and post hoc Bonferroni were used to analyse dental anxiety in the psychometric constructs.

RESULTS

The internal consistency of MDAS-K was good with Cronbach's alpha of 0.83. The test-retest reliability for MDAS K had a good correlation of 0.901. The psychometric variables established the construct validity of MDAS-K.MDAS-K also showed good convergent validity with VAS score. The anxiety levels differed in patients visiting different dental departments.

CONCLUSION

The high reliability and validity of the MDAS-K supports its cross cultural adaptation and indicates that it can be a valuable tool for dental practioners in quantifying anxiety among patients and provide quality dental care.
