We examined the correlates of the Quality of Life Index (QLI) in three samples of cancer patients: newly diagnosed (N = 397), recipients of chemotherapy (N = 194), and terminal (N = 2046). The relative importance of physical, emotional, social, and disease symptom characteristics in predicting the QLI was compared across samples. Despite differences in data collection approaches (telephone, personal interview, or paper and pencil) and differences in patient characteristics, the QLI was a robust construct with its central organizing principle being physical functioning. In all samples, functioning, symptoms, depression, and social support were significant predictors of the QLI, while age and cancer type were only minimally related. The QLI significantly differentiated between patients at different disease phases and measured more than physiological functioning. However analyses suggested that the dominant factor constraining the range of human psychosocial functioning was physical condition.
我们在三组癌症患者样本中研究了生活质量指数（QLI）的相关因素：新确诊患者（N = 397）、接受化疗的患者（N = 194）以及晚期患者（N = 2046）。我们比较了身体、情绪、社会和疾病症状特征在预测QLI方面的相对重要性。尽管数据收集方法（电话、个人访谈或纸笔）存在差异，且患者特征也有所不同，但QLI是一个稳健的结构，其核心组织原则是身体功能。在所有样本中，功能、症状、抑郁和社会支持都是QLI的显著预测因素，而年龄和癌症类型的相关性极小。QLI能够显著区分不同疾病阶段的患者，且测量的不仅仅是生理功能。然而，分析表明，限制人类心理社会功能范围的主要因素是身体状况。
