Background: Life balance is defined as having a satisfying pattern of activities or occupations that is sustainable and meaningful to a person within their current context and life conditions. It can be considered an important outcome in medical and rehabilitation services. The Life Balance Inventory (LBI) is a self-reported, comprehensive measure developed to evaluate life balance. This study aimed to translate and validate the LBI for the Iranian population.Methods: This methodological and cross-sectional study included a sample of 150 healthy individuals and 93 people with mental illnesses. Validation procedures included content validity, discriminant validity (construct validity), test-retest reliability, and internal consistency assessment of the LBI.Results: The Persian translation of the LBI demonstrated acceptable content validity. Discriminant validity showed significant differences in life balance between healthy individuals and those with mental disorders. Test-retest reliability ranged from 0.70 to 0.93 over a two-week interval. Internal consistency was strong, with a Cronbach’s alpha of 0.88.Conclusion: The LBI shows acceptable psychometric properties for use among Iranians. This questionnaire effectively discriminates between individuals with and without mental disorders. The Persian version of the LBI can be applied in various specialties and settings.
