Health-Related Quality of Life After Stroke

A Danish version of the Stroke-Specific Quality of Life Scale (SSQOL-DK) has been developed for self-reporting; it contains 12 physical and psychosocial domains. The purpose of this study was (a) to assess the reliability of the proxy version of the SSQOL-DK and (b) to evaluate the influence of frequency of proxy contact on agreement. In all, 143 patients completed the SSQOL-DK 1 to 5 years post-stroke. A patient chosen proxy completed a proxy version of the same questionnaire. The proxy version showed satisfactory internal consistency (Cronbach's α = .85-.95). Agreement was generally high. Proxies rated the amount of trouble significantly smaller (higher score) than the patients only in the domain Social Roles. The amount of trouble in the domain Family Roles received significantly higher ratings from noncohabitant proxies when compared with patients (lower score). The proxy version of the SSQOL-DK appears to be reliable for use with stroke patients up to a few years following a stroke.
