Psychometric properties of the Chinese version of the Subarachnoid Hemorrhage Outcomes Tool (SAHOT) in elderly SAH patients

Elderly patients with subarachnoid hemorrhage (SAH) experience long-term disability and persistent cognitive and psychosocial sequelae, with poor patient-reported outcomes (PROs). However, China currently lacks tools to assess PROs in elderly SAH patients. This study aims to translate the Subarachnoid Hemorrhage Outcomes Tool (SAHOT) into Chinese and evaluate its psychometric properties among elderly SAH patients in China. A cross-sectional study involving 404 elderly patients with subarachnoid hemorrhage (SAH) was conducted. The original scale was translated into Chinese using the Brislin translation technique. The reliability of the Chinese version of the SAHOT was assessed through internal consistency and split-half reliability. Its validity was evaluated using content validity, convergent validity, and criterion validity. The Chinese version of the SAHOT (C-SAHOT) comprises 4 dimensions and 56 items, demonstrating excellent internal consistency (Cronbach’s α = 0.964) and split-half reliability (0.761). The content validity index at the scale level is 1.0; AVE values for each dimension ranged from 0.592 to 0.627, while CR values ranged from 0.943 to 0.964. The C-SAHOT showed a significant negative correlation with scores on the Short Form Stroke Quality of Life Scale (r = -0.674, P < 0.001). Exploratory factor analysis revealed a four-factor structure explaining 64.730% of total variance. The Chinese version of SAHOT demonstrates good reliability and validity among elderly SAH patients in China. It effectively measures the PROs levels of these patients, providing a basis for their PROs management.
