Development and validation of the Iranian version of the Children's Experiences of Dental Anxiety Measure (CEDAM)

Abstract

Objective: The aim of this study was to develop the Iranian version of the Children's Experiences of Dental Anxiety Measure (CEDAM) and evaluate its validity and reliability in assessing dental anxiety in children aged 9‒16. Methods: The CEDAM was translated into Persian following the guidelines of the IQOLA project. A ‎sample of children completed the measure in a clinical setting, with a subgroup completing it ‎again to assess test–retest reliability. Concurrent criterion validity was evaluated by having all ‎participants complete the Modified Child Dental Anxiety Scale (MCDAS) alongside the ‎CEDAM. Construct validity was examined using exploratory and confirmatory factor ‎analyses.‎. Results: The study included 275 children between the ages of 9 and 16. The Iranian version of CEDAM ‎exhibited excellent internal consistency with a Cronbach's ⍺ coefficient of 0.83. Test–retest ‎reliability was also high, with an intraclass correlation coefficient value of 0.96. Furthermore, there was a significant and ‎positive correlation between CEDAM and MCDAS scores (ρ = 0.72, p
