Abstract
We herein describe the development and validation of the Cancer Fatigue Sca le (CFS) for assessment of fatigue in cancer patients. We designed this sca le specifically to reflect the nature of fatigue experienced by cancer pati ents, by using factor analysis; the CFS is a 15-item scale composed of 3 su bscales (physical, affective, and cognitive subscales). Three hundred seven cancer patients participated in the validation phase. Construct validity, confirmed by repeating factor analysis, was good. Convergent validity, conf irmed by a correlation between CFS and a visual analogue scale for fatigue, was also shown to be good (r = 0.67, P < 0.001). The CFS had good stabilit y (average test-retest reliability r = 0.69, P < 0.001) and good internal c onsistency (Cronbach's alpha coefficient for all 15 items = 0.88). The pres ent study indicates that the CFS is a brief, valid, and feasible measure of fatigue for use with cancer patients. (C) U.S. Cancer Pain Relief Committe e, 2000.
