Background: The identification of aneurysmal subarachnoid hemorrhage (aSAH) patients with a decrease in health-related quality of life (HRQOL) is challenging. Stroke-Specific Quality of Life (SS-QOL) Scale is one of the commonest disease-specific quality of life measures initially developed and validated for ischemic stroke patients. A disadvantage is subject burden and a short form is more practical to use in clinical and research setting. Aim: This study aimed to develop a short form (12-item) of a Chinese version of Stroke-Specific Quality of Life Scale for aSAH (SSQOL-a) for clinical and research applications. Methods: We carried out a prospective observational assessor-blinded multi-center study in Hong Kong. The study was registered at ClinicalTrials.gov of the U.S. National Institutes of Health (NCT01038193), and was approved by hospital ethics committees. Results: One hundred and eighty-six aSAH patients were recruited over a 30 month period during admission. One hundred (54%) aSAH patients completed the 12-month assessment battery and were included into the current study. The total score, physical component score, and psychosocial score of the 12-item Chinese version showed satisfactory internal consistency and explained high percentages of variance of the full Chinese version (92% to 96%). The 12-item Chinese version showed significant correlations with neurological, functional, generic quality of life, psychiatric, and cognitive outcome measures at 12 months. Chinese version calculated physical subscore had better discrimination in detecting complete recovery than the Dutch version calculated physical subscore in our Chinese population. Conclusions: The 12-item Chinese version of SSQOL-a has a satisfactory internal consistency and criterion validity for SAH patients at 12 month assessments. (c) 2013 Elsevier B.V.
