Development and evaluation of psychometric properties on psychosocial adaptation scale for stroke

People with stroke often experience significant psychosocial consequences that can impact their daily lives, making it vital to assess their ability to adapt following the event. The objective was to develop a reliable and valid scale, the Psychosocial Adaptation Scale for Stroke (PASS) while evaluating its psychometric properties. Firstly, a comprehensive literature review, team discussion, Delphi survey, cognitive interview and item analysis were used to identify and optimize indicators to form the preliminary scale. Secondly, a cross-sectional survey was conducted among 441 participants with stroke in China. Validity analysis included content validity, criterion validity, structural validity, and convergent validity. Cronbach’s α and test-retest reliability were calculated for reliability analysis. Five factors were extracted, resulting in a final 31-item scale. Confirmatory factor analysis demonstrated acceptable model fit and supported the 5-factor structure. The scale showed good criterion validity with the PAIS-SR ( r = 0.642, P < 0.01) and convergent validity with the SSQOL ( r = –0.534, P < 0.01). Cronbach’s α and test-retest reliability ranged from 0.874 to 0.961 and 0.783 to 0.953, respectively. PASS is a reliable and valid instrument for assessing the psychosocial adaptation among people with stroke. not applicable.
