Purpose: The Adapted Fresno Test (AFT) is a seven-item instrument for assessing knowledge and skills in the major domains of evidence-based practice (EBP), including formulating clinical questions and searching for and critically appraising research evidence. This study examined the interrater reliability of the AFT using several raters with different levels of professional experience. Method: The AFT was completed by physiotherapists and occupational therapists, and a random sample of 12 tests was scored by four raters with different levels of professional experience. Interrater reliability was calculated using intra-class correlation coefficients (ICC [2, 1]) for the individual AFT items and the total AFT score. Results: Interrater reliability was moderate to excellent for items 1 and 7 (ICC ¼ 0.63-0.95). Questionable levels of reliability among raters were found for other items and for the total score. For these items, the raters were clustered into two groups-''experienced'' and ''inexperienced''-and then examined for reliability. The reliability estimates for rater 1 and rater 2 (''inexperienced'') increased slightly for items 2 and 5 and for the total score, but not for other items. For raters 3 and 4 (''experienced''), ICCs increased considerably, indicating excellent reliability for all items and for the total score (0.80-0.99), except for item 4, which showed a further decrease in ICC. Conclusion: Use of the AFT to assess knowledge and skills in EBP may be problematic unless raters are carefully selected and trained.Key Words: Adapted Fresno Test; evidence-based practice; occupational therapy; physical therapy specialty; reproducibility of results.
RÉ SUMÉObjectif : Le test adapté de Fresno (Adapted Fresno Test, AFT) est un instrument de mesure en sept points qui vise l'é valuation des connaissances et des compé tences dans les principaux domaines de pratique fondé e sur des faits probants, notamment la formulation de questions cliniques et la recherche ainsi que l'é valuation critique de preuves issues de la recherche. L'é tude s'est penché e sur la fiabilité de l'AFT entre é valuateurs, en travaillant avec des é valuateurs ayant divers degré s d'expé rience professionnelle. Mé thodologie : Des physiothé rapeutes et des ergothé rapeutes ont procé dé à un AFT. Un é chantillon alé atoire de 12 tests a ensuite é té analysé par quatre é valuateurs avec des degré s varié s d'expé rience professionnelle. La fiabilité entre é valuateurs a é té calculé e à l'aide de coefficients de corré lation intraclasse (CCI [2, 1]) pour les points individuels de l'AFT et pour le pointage total de l'AFT. Ré sultats : La fiabilité entre é valuateurs variait de modé ré e à excellente pour les points 1 et 7 (CCI ¼ 0,63-0,95). Pour les autres points et pour la note totale toutefois, les niveaux de fiabilité sont sujets à caution. Pour les points en question, les é valuateurs ont é té sé paré s en deux groupes-les « expé rimenté s » et les « inexpé rimenté s »-et leur fiabilité a ensuite é té analysé e. Les estimations d...
