Abstract
Background: Occupational balance (OB) is an important concept in occupational therapy and is considered as an essential component of health and well-being.Aim: The aim of this study was to investigate the validity and reliability of the Turkish version of the Occupational Balance Questionnaire-11 (OBQ11-T).Materials and methods: The OBQ11-T was administered to 116 individuals for construct validity analysis and to 58 individuals for reliability analysis. Validity was determined using explanatory and confirmatory factor analysis. In confirmatory factor analysis, RMSEA (root mean square error of approximation) value, comparative fit index (CFI), and Chi-square to degrees of freedom ratio (CMIN/DF) were analysed. The test-retest method and Cronbach's alpha coefficient were used to assess the reliability and internal consistency of the OBQ11-T, respectively. Results: The model fit the data according to the indices of relative fit (RMSEA = 0.076, CMIN/DF = 1.661, and CFI = 0.875). The correlation coefficient between test and retest OBQ11-T total scores was 0.922. Total scores showed a significant statistical relationship (p < 0.01), indicating good reliability. Cronbach's alpha for OBQ11-T total score was 0.785, indicating acceptable internal consistency.Conclusions and significance: The current study demonstrates that the OBQ11-T is a valid and reliable tool for measuring the self-rated OB of healthy individuals.
