Fatigue is the most distressing untreated symptom for many cancer patients, and its measurement is of great topical interest. The aim of the present study was to assess psychometric properties of Revised Piper Fatigue Scale (PFS-r) in Italian cancer patients.
From January to June 2007, 115 histologically confirmed cancer inpatients (age >or=18 years; Eastern Cooperative Oncology Group [ECOG] performance status <or=2), who were undergoing treatments, completed the Italian PFS-r and the Profile Of Mood States (POMS) Fatigue and Vigor subscales. Major psychometric properties were investigated.
The construct validity of the Italian PFS-r was appropriate, with high corrected item-subscale correlations (Pearson r >or=0.97) for all subscales. Exploratory factor analysis revealed three dimensions instead of four in the US questionnaire; 68.2% of the common variance was explained. Internal consistency was satisfactory (Cronbach's alpha >0.80) as was the test-retest reliability. Good correlations between PFS-r subscale and POMS subscales confirmed criterion validity.
The psychometric properties of the Italian version of PFS-r, as evaluated in cancer patients ongoing chemotherapy, were satisfactory. We suggest the possible implementation of the Italian PFS-r in the assessment of fatigue particularly when it has been more fully validated on a wider range of cancer patients.
疲劳是许多癌症患者未得到治疗的最痛苦的症状，因此对其进行测量具有重要的现实意义。本研究旨在评估修订版 Piper 疲劳量表（PFS-r）在意大利癌症患者中的心理测量特性。
2007 年 1 月至 6 月，115 名经组织学证实的癌症住院患者（年龄>或=18 岁；东部肿瘤协作组[ECOG]体能状态<或=2）接受了治疗，他们完成了意大利 PFS-r 和状态-特质焦虑问卷（POMS）疲劳和活力子量表。主要心理测量特性进行了调查。
意大利 PFS-r 的结构效度较好，所有子量表的校正项目-子量表相关性均较高（Pearson r >或=0.97）。探索性因子分析显示，美国问卷中有四个维度变为三个维度；共同方差的 68.2%得到了说明。内部一致性较好（Cronbach's alpha >0.80），重测信度也较好。PFS-r 子量表与 POMS 子量表之间的良好相关性证实了其标准效度。
在接受化疗的癌症患者中评估的意大利版 PFS-r 的心理测量特性令人满意。我们建议在更广泛的癌症患者中进一步验证后，可能会在疲劳评估中实施意大利 PFS-r。
