Psychometric properties of the HIV-Related Fatigue Scale.
The HIV-Related Fatigue Scale (HRFS) was developed to address the specific aspects of fatigue experienced by people who are HIV-positive and are not measured in any commonly used fatigue scale. The necessity for a new scale was determined after analysis of a qualitative study to explore HIV-related fatigue in which it was found that HIV-related fatigue has components related to intensity, circumstances, and consequences that must be included in the measurement of fatigue for this population. The HRFS has 56 items, most of which are on a 1-to-10 scale, drawn from five existing fatigue scales and the data from this qualitative study. The items were deemed content valid, easy to understand, and not fatiguing to complete by people with HIV-related fatigue. Cronbach's alpha for the entire tool was .94; internal consistency for each of the three preliminary subscales is reported as well. Test-retest reliability was moderate at r = .43. Further testing needs to be done, but the HRFS has the potential to be a valuable addition to the measurement of fatigue in seropositive persons.
