“…A previously performed factor analysis of the Swedish version [16] also indicated a possible division, reflected by the magnitudes of the factor loadings of the first two items compared with those of the latter three, even though the subscale held together. A single domain comprising Cognitive/Mood failed to be supported, corroborating earlier factor analytical studies both for the Swedish version [16] and for other international versions [10,13,14]. A bifactor solution with each of the three original domains treated as testlets, and with Cognitive/Mood treated as separate testlets (so making five in all), does support a dominant common factor, and with most of the nonerror variance being common, the summated raw score is, in practice, a sufficient statistic for estimating fatigue.…”

“…Subscales and total score range from 0 to 10 in the original version, with higher values indicating more intense fatigue. To date, the RPFS has been translated into Chinese [8] and Greek [9] and validated for use in France [10], The Netherlands [11], Brazil [12], and Italy [13,14].…”

“…Three psychometric studies of non-English translations of the PFS-R, Greek [9], French [10] and Italian [34], also identified the same 4 subscales. In contrast, two studies found evidence for a 3-factor solution combining the domains of sensory with cognition/mood.…”

Purpose Brief, valid measures of fatigue, a prevalent and distressing cancer symptom, are needed for use in research. This study’s primary aim was to create a shortened version of the revised Piper Fatigue Scale (PFS-R) based on data from a diverse cohort of breast cancer survivors. A secondary aim was to determine whether the PFS captured multiple distinct aspects of fatigue (a multidimensional model) or a single overall fatigue factor (a unidimensional model). Methods Breast cancer survivors (n=799; stages in situ through IIIa; ages 29–86 yrs) were recruited through 3 SEER registries (New Mexico, Western Washington, and Los Angeles, CA) as part of the Health, Eating, Activity, and Lifestyle (HEAL) study. Fatigue was measured approximately 3 years post-diagnosis using the 22-item PFS-R that has 4 subscales (Behavior, Affect, Sensory, and Cognition). Confirmatory factor analysis was used to compare unidimensional and multidimensional models. Six criteria were used to make item selections to shorten the PFS-R: scale’s content validity, items’ relationship with fatigue, content redundancy, differential item functioning by race and/or education, scale reliability, and literacy demand. Results Factor analyses supported the original 4-factor structure. There was also evidence from the bi-factor model for a dominant underlying fatigue factor. Six items tested positive for differential item functioning between African-American and Caucasian survivors. Four additional items either showed poor association, local dependence, or content validity concerns. After removing these 10 items, the reliability of the PFS-12 subscales ranged from 0.87–0.89, compared to 0.90–0.94 prior to item removal. Conclusion The newly developed PFS-12 can be used to assess fatigue in African-American and Caucasian breast cancer survivors and reduces response burden without compromising reliability or validity. This is the first study to determine PFS literacy demand and to compare PFS-R responses in African-Americans and Caucasian breast cancer survivors. Further testing in diverse populations is warranted.

“…For example, an Italian study of cancer patients included relaxed/tense in the affective meaning subscale rather than the sensory subscale [32]. The Dutch version of the revised PFS for breast and lung cancer patients reported that all items were matched with the items of the original subscales [33].…”

Validation of the revised piper fatigue scale in Koreans with chronic hepatitis B

PurposeThe 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.MethodsA 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.ResultsThe factor analysis supported the original four-factor structure based on Kaiser Criterion and Minimum Average Partial (MAP): Behavioral/Severity, Affective meaning, Sensory, & 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.ConclusionsThe 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.

The Revised Piper Fatigue Scale (PFS-R) for Italian Cancer Patients: A Validation Study

Abstract: Despite the discussed limitations, PFS-R seems a valid and reliable multidimensional fatigue measure also adequate in Italian oncological settings.
