Validity and reliability of the Lithuanian Occupational Balance Questionnaire

Occupational balance is an important concept in occupational therapy. However, no validated Occupational balance assessments currently exist in Lithuania. This study aimed to examine the psychometric properties of the Lithuanian version of the Occupational Balance Questionnaire 11 (OBQ11-LT).

A total of 127 healthy adults completed the OBQ11-LT to evaluate construct validity. Of these, 53 participants were randomly assigned to complete the questionnaire again after 7-10 days to assess test-retest reliability. Construct validity was examined using exploratory and confirmatory factor analyses. Test-retest reliability was evaluated using the intraclass correlation coefficient (ICC) for both total scores and individual items. Internal consistency was assessed with Cronbach's alpha.

The model demonstrated acceptable fit (χ²(45) = 719.79, p < 0.001; CFI = 0.933; TLI = 0.909; RMSEA = 0.106). The ICC between test and retest OBQ11-LT total score was 0.924. Total scores showed a significant statistical relationship (p < 0.01), indicating good reliability. Cronbach's alpha for the OBQ11-LT total score was 0.915, indicating acceptable internal consistency.

OBQ11-LT demonstrates good reliability and validity for assessing occupational balance in general populations. Its psychometric properties are suitable for practice and research, making it a valuable tool for studying occupational balance in similar contexts and broadening the research areas for Lithuanian occupational therapists.
