Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale at Baseline and Month 3
FACIT-Fatigue Scale (FS):13-item questionnaire, participant scored each item on a 5-point scale: 0 (not at all) to 4 (very much). The larger the participant's response to the questions (with the exception of 2 negatively stated), the greater the fatigue. For all questions, except for the 2 negatively stated ones, the code was reversed and a new score was calculated as 4 minus the participant's response. The sum of all responses resulted in the FACIT-FS for a total possible score of 0 (worse score) to 52 (better score). A higher score reflected an improvement in the participant's health status.
