The purpose of this study was to develop and evaluate the reliability and validity of the Cognitive Appraisal of Disability for Stroke (CADS).
Questionnaire content was based on the work of Lazarus (1984) and 24 items were generated from “A Qualitative Analysis on Problems Recognized by Patients” by Konishi. In pretest, the CADS was significantly correlated with the Cognitive Appraisal of Health Scale (r = .814, p＜0.001), Cronbach’s Alpha was .809 and test-retest reliability coefficient was .976 (p＜0.001).
The CADS was tested in a sample of 105 stroke victims. Five factors were identified through factor analysis using a principal factor method with varimax rotation and the CADS was reduced to 18 items. All factors were good reflections of psychometric components for cognitive appraisal classified by Lazarus, indicating construct validity. Cronbach’s Alpha was .833, indicating internal consistency in re li ability.
Thus, the CADS was found to have both reliability and validity as a scale for measuring the psychometric components of cognitive appraisal of disability for stroke.
