Validation and internal consistency of the Swedish version of the Valued Life Activities scale.

• OBJECTIVE: The objective was to create a linguistically and culturally validated Swedish version of the Valued Life Activities scale. The aim was also to describe its content and concurrent validity and its internal consistency in persons with rheumatoid arthritis.METHODS: The Valued Life Activities scale was translated to Swedish and culturally adapted. In order to describe the content validity, both the Swedish and original Valued Life Activities scale were linked to the International Classification of Functioning, Disability and Health. The concurrent validity and internal consistency were evaluated in 737 patients with rheumatoid arthritis. To establish concurrent validity, the scale was correlated to disease activity, activity limitations, and life satisfaction. Internal consistency was assessed with Cronbach's alpha.RESULTS: The equivalence of meaning between the Swedish and the original Valued Life Activities scale was ensured by harmonization review. Content validity was high when linked to the International Classification of Functioning, Disability and Health. Concurrent validity showed a strong correlation with the activity limitations (r = 0.87), moderate with life satisfaction (r = -0.61), and weak with disease activity (r = 0.38). Internal consistency was excellent (Cronbach's alpha = 0.97).CONCLUSIONS: The Swedish Valued Life Activities scale has been tested in a large and well-characterized sample and found to be a linguistically valid and culturally adapted self-reported measure of participation. Content validity of the Valued Life Activities scale was excellent, concurrent validity strong, and the internal consistency excellent. Since both individual preferences and International Classification of Functioning, Disability and Health concepts of disability are taken into account, the Swedish Valued Life Activities scale appears to be a promising new scale addressing important aspects of participation.
