Abstrakt:	Background: The widely-used Dental Anxiety Scale (DAS) has practical and theoretical limitations. The Index of Dental Anxiety and Fear (IDAF-4C) was developed to overcome these shortcomings but requires more psychometric analysis to determine its utility. Purpose: To compare DAS and IDAF-4C validity and reliability among New Zealand Defence Force (NZDF) personnel. Material and methods: A survey of NZDF recruits and officer cadets collected data on dental anxiety using the IDAF-4C, the DAS and a global dental anxiety item. Results: Some 134 individuals completed the questionnaire. Confirmatory factor analysis for the IDAF-4C showed that a single factor explained 72.4% of the variance. The IDAF-4C showed high internal consistency reliability (α = 0.94). Confirmatory factor analysis for the DAS showed that a single factor explained 69.5% of the variance. The DAS showed high internal consistency reliability (α = 0.85). While the IDAF-4C showed a consistent gradient in mean scale scores across response categories of the global dental anxiety question, the gradient for the DAS was less consistent. The IDAF-4C and DAS showed considerable concordance (r = 0.71). Conclusion: The IDAF-4C demonstrated excellent psychometric properties, validity and reliability, and it is a valid and useful instrument for measuring dental anxiety and fear in Defence Force personnel.
