疲劳是癌症患者经历的最常见和使人衰弱的症状之一，但直到近年来，它很少受到系统的关注，部分原因是缺乏足够的仪器来测量疲劳。本报告的主要目的是进一步验证最近开发的用于癌症患者的疲劳测量：疲劳症状量表（FSI）。这个13项自我报告测量旨在测量疲劳的强度和持续时间及其对生活质量的干扰。FSI最初在乳腺癌患者样本和健康个体样本中得到验证。在这项研究中，FSI在门诊样本中进行了评估，其中包括男性和女性癌症患者，以及一些老年患者，具有各种癌症诊断。一个七项干扰量表被发现有良好的内部一致性，α系数大于0.90。收敛的有效性证明了通过与现有的措施疲劳。结构效度通过与生活满意度和抑郁度的比较以及预期疲劳体验不同的患者亚组之间的比较来证明。总体而言，FSI被进一步确立为癌症患者疲劳的有效和可靠的测量方法。这一措施在心理社会肿瘤学研究的潜在应用进行了讨论。
Fatigue is one of the most common and debilitating symptoms experienced by cancer patients, yet until recent years it has received little systematic attention, due in part to the lack of adequate instruments to measure fatigue. The primary aim of this report is to further validate a recently developed measure of fatigue for use with cancer patients: the Fatigue Symptom Inventory (FSI). This 13-item self-report measure was designed to measure the intensity and duration of fatigue and its interference with quality of life. The FSI was originally validated in a sample of breast cancer patients and a sample of healthy individuals. In this study, the FSI was evaluated in an outpatient sample that included male and female cancer patients, as well as some older patients, with a variety of cancer diagnoses. A seven-item interference scale was found to have good internal consistency, with alpha coefficients above 0.90. Convergent validity was demonstrated via comparisons with an existing measure of fatigue. Construct validity was demonstrated via comparisons with measure of life satisfaction and depression as well as comparisons among subgroups of patients expected to differ in their experience of fatigue. Overall, the FSI was further established as a valid and reliable measure of fatigue in cancer patients. The potential application of this measure in psychosocial oncology research is discussed.
