Translation, cultural adaptation and psychometric properties of the Persian version of Occupational Balance Questionnaire in healthy adults

Introduction: Occupational balance is a fundamental concept that plays an influential role in enhancing health and well-being. Method: The Persian Occupational Balance Questionnaire-11 was administered to 157 healthy individuals in the test phase and 80 healthy individuals in the retest phase. Floor or ceiling effects, construct validity, discriminant validity, internal consistency reliability, test-retest reliability, standard error of the measurement and smallest detectable change were examined. Results: The Persian Occupational Balance Questionnaire-11 showed no missing responses. There were no floor or ceiling effects for the total score. The independent t-test did not show a statistically significant difference between groups (based on age category, marital status and job status) that didn't support discriminant validity. Factor analysis demonstrated a three-factor solution for the Persian Occupational Balance Questionnaire-11 which jointly accounted for 57.62% of the total variance. There was high internal consistency for test (alpha = 0.813) and retest (alpha = 0.853). The test-retest reliability for Persian Occupational Balance Questionnaire-11 with a 1-week interval was excellent (ICCagreement = 0.880). The standard error of the measurement and smallest detectable change were 2.02 and 5.60, respectively. Conclusion: Persian Occupational Balance Questionnaire-11 is a valid and reliable instrument for assessing occupational balance in healthy Persian-speaking participants.
