The life balance inventory in patients with multiple sclerosis: Cross-cultural adaptation, reliability and validity of the Turkish version

The aim of the study was to present the psychometric properties of the Turkish version of the life balance inventory in individuals with multiple sclerosis. Life balance inventory was translated and adapted considering common suggestions. Participants were cross-sectionally evaluated twice with life balance inventory, with a 1-week interval. Expanded Disability Status Scale, Beck Depression Scale, and Short Form-12 were used to assess the convergent validity. A total of 113 individuals with multiple sclerosis were enrolled in the study. Test-retest reliability of the total score and all subscores of the life balance inventory were excellent (intraclass correlation coefficient > 0.80). The internal consistency of the life distress inventory was excellent (α = 0.73–0.95). The correlation of Expanded Disability Status Scale with life balance inventory and its subscores was low in the scope of divergent validity, as expected ( r < 0.35). The correlation between life balance inventory total score and Expanded Disability Status Index was −0.337 ( p < 0.01). Life balance inventory scores were moderately correlated ( p < 0.01), except life balance inventory health score. Life balance inventory scores were correlated with SF-12 physical-subscales and mental-subscales, in a low and moderate degree, respectively. The life balance inventory total score was highly correlated with the life balance inventory subscores ( r = 0.69–0.96, p < 0.01). The Turkish life balance inventory is a reliable and valid inventory in patients with multiple sclerosis. Life balance inventory comprehensively evaluates the life balance parameters of multiple sclerosis patients.
