Psychometric Properties of Patient-Reported Outcomes Measurement Information Systems (PROMIS) Computer Adaptive Test (CAT) - Fatigue in Individuals Receiving Chronic Hemodialysis Therapy: A Secondary Analysis.

The purpose of this secondary analysis was to report the psychometric properties of the Patient-Reported Out comes Measurement Information Systems (PROMIS) Computer Adaptive Test (CAT) - Fatigue in individuals receiving hemodialysis (HD) treatment. Measures included Piper Fatigue Scale-12, Six-Minute Walk Test, PROMIS CAT-Fatigue, and Charlson Comorbidity Index. English-speaking adults older than 18 years, cognitively intact, receiving two to three times weekly HD treatment were included. A total of 86 individuals (M = 61.7 years, SD = 13.81), predominantly males (58.1%), and African American (48.8%), completed PROMIS CAT-Fatigue; with a mean t score of 55.9 (SD = 9.17). Almost 39% (n = 33) of participants were classified as fatigued. Floor-ceiling effects, reliability, convergent validity, and clinical validity of PROMIS CAT-Fatigue was established. Further research on PROMIS CAT-Fatigue in larger dialysis populations is warranted.
