The Psychometric Property Evaluation of the Turkish Version of the Osteoporosis Awareness Scale

Abstract

Objective: This study aimed to determine the validity and reliability of the Turkish version of the Osteoporosis Awareness Scale (OAS) developed to assess people's osteoporosis awareness. Materials and Methods: This methodological study was designed to investigate the validity and reliability of the "OAS" in Turkish society. This study included healthcare workers who worked in Community Health and Family Health Centers (n=346). Numbers, percentages, t-test, correlation analysis, Cronbach's alpha reliability coefficient, and factor analysis methods were used to analyze the data. Results: The Cronbach's alpha reliability coefficient was 0.94 for the overall OAS and 0.86, 0.82, 0.88, 0.88, 0.85 for its bone physiology, preventive behaviors, risk factors, exercise, and characteristics of osteoporosis sub-dimensions, respectively. The exploratory factor analysis demonstrated that the scale explained 66.16% of the total variance. According to the confirmatory factor analysis, factor loadings of the scale ranged between 0.64 and 0.82, and CMIN(x2)/df was 3.384, goodness-of-fit index was 0.85, normed fit index was 0.83, comparative fit index was 0.88, and RMSEA was 0.08. Conclusion: Results indicate that the Turkish version of the OAS highly valid and reliable, which can be administered in future studies.
