Fatigue is a contributor to decreased quality of life and one of the most common symptoms reported by cancer survivors. Most assessment of fatigue has been retrospective and/or unidimensional. Single-item visual analogue scale ratings are commonly used, despite arguments that fatigue is better conceptualized as multidimensional. The relationships of daily to weekly ratings of fatigue, or of unidimensional to multidimensional assessments, have not been explored. Twenty-five breast cancer survivors provided daily ratings of fatigue and completed the Multidimensional Fatigue Symptom Inventory-Short Form weekly for one month. Using hierarchical linear modeling, stronger relationships of weekly ratings to average and peak rather than most recent daily ratings were found. Visual analogue scale ratings shared more variance with the General Fatigue subscale than with the other four fatigue dimensions measured. Findings suggest that different information is captured by daily versus weekly reports, and that although visual analogue scale ratings can provide a quick assessment of general fatigue, they do not capture other important dimensions.
疲劳是导致生活质量下降的一个因素，也是癌症幸存者报告的最常见症状之一。大多数对疲劳的评估都是回顾性的和/或单维度的。尽管有人认为疲劳最好被概念化为多维度的，但单项视觉模拟量表评分仍被普遍使用。每日疲劳评分与每周疲劳评分之间的关系，或者单维度评估与多维度评估之间的关系尚未得到探讨。25名乳腺癌幸存者提供了每日疲劳评分，并在一个月内每周完成一次多维疲劳症状量表简表。使用分层线性模型发现，每周评分与平均和峰值疲劳评分的关系比与最近每日评分的关系更强。视觉模拟量表评分与一般疲劳子量表的方差共享比与所测量的其他四个疲劳维度更多。研究结果表明，每日报告和每周报告所获取的信息不同，尽管视觉模拟量表评分可以快速评估一般疲劳，但它们无法捕捉其他重要维度。
