The Psychometric Properties of the Turkish Version of Revised 2011-Osteoporosis Knowledge Test

Abstract

Objective: The aim of this study was to translate the revised 2011-Osteoporosis Knowledge test (R-OKT) into Turkish and to assess its reliability. Materials and Methods: After the translation process, the study was performed with healthy volunteers who accepted to participate in the study. Demographic features, level of nutrition and physical activity were recorded. Participants were fulfilled the R-OKT. Cronbach-α was calculated for internal consistency, intraclass correlation coefficient was calculated for test-retest reliability by using two tests fulfilled with 2 days interval. Validation study was performed by Spearman’s correlation between nutrition and exercise subscales of R-OKT with calcium intake and level of physical activity. Results: The study was carried out with 82 participants with a mean age of 41.3±12.6 years. Cronbach-α values for the nutrition subscale, exercise subscale and total score was found as 0.71, 0.76 and 0.76, respectively. Test-retest reliability was calculated above 0.90 for both of the subscales and total score. When R-OKT subscales were compared with calcium intake and exercise level in daily living, significant relationship was found between R-OKT nutrition subscale and the level of calcium intake. Conclusion: Turkish version of R-OKT is a reliable scale to assess the level of osteoporosis knowledge.
