Abstract

Objective: The aim of this study was to provide a reliable instrument to assess evidence-based practice (EBP) dimensions in French-speaking dental students. To do so, a transcultural adaptation into French of the self-administered KACE questionnaire (Knowledge, Attitude, Access and Confidence Evaluation) and the evaluation of its psychometric properties in a sample of French dental students and teachers were performed. The effects of individual and academic factors on student performance in the KACE were also investigated.

Method: Teachers and fourth-year students completed once the translated KACE and fifth-year students completed twice the questionnaire before and after an epidemiology course. Cronbach's alpha coefficient analysis, Kruskal-Wallis and post hoc Dunn's tests, paired samples Wilcoxon tests and a generalised linear mixed model were performed to assess the psychometric properties (reliability, internal consistency, discriminant validity and responsiveness) of the questionnaire and to identify the factors associated with KACE scores, respectively.

Results: 186 participants completed the survey. Cronbach's alpha ranged from 0.06 to 0.48 for Knowledge, 0.21 to 0.59 for Attitude, 0.42 to 0.76 for Access and 0.82 to 0.93 for Confidence. The discriminant value and sensitivity of the French KACE revealed significant differences amongst students and teachers and accurately identified the effect the training course had on the students who had completed it. Preparing for a residency programme or having received add-on modules in science improved the students' performance in the test. Being female negatively impacted the KACE Confidence score.

Conclusion: This version of the KACE is appropriate to assess EBP dimensions in French dental students. Academic background and gender may affect test performance.
