Purpose

The purpose of the study was to evaluate the construct validity and reliability of the Korean version of the revised Piper Fatigue Scale PFS in Koreans with chronic hepatitis B.

Methods

A total of 146 chronic hepatitis B patients completed the Korean version of the revised PFS. A descriptive analysis was performed to determine the subjects’ demographic characteristics; the construct validity was examined using exploratory factor analysis; and internal consistency reliability of the scale was estimated for the meaningful total scale and factors.

Results

The factor analysis supported the original four-factor structure based on Kaiser Criterion and Minimum Average Partial MAP: Behavioral-Severity, Affective meaning, Sensory, and Cognitive-Mood. In the 22 items in the original instrument, patient-impatient, relaxed-tense, and exhilarated-depressed were re-identified from the cognitive-mood subscale and sensory subscale. The Cronbach’s alpha of the 22-item Korean version of the revised PFS was 0.96 for the total scale, and the range of Cronbach’s alpha for subscales was 0.90 to 0.93.

Conclusions

The results of the study revealed that the 22-item Korean version of the revised PFS is valid and reliable in Koreans with chronic hepatitis B. Further studies ascertaining the psychometric properties of the revised PFS need to be performed in Korean patients.
