Although quality of life evaluations are widely used throughout medicine, relatively little is known about the psychological processes involved in making these judgements. What is known is that quality of life judgements are not straightforwardly associated with objective measures of health status or clinician ratings. In particular, patient affect appears to be associated with quality of life ratings but whether this relationship is secondary to physical health or not is controversial. The aim of this study was to determine the role of anxiety and depression in the reporting of quality of life in a group of patients with diabetes mellitus. One hundred consecutive patients with diabetes (insulin-dependent diabetes mellitus n = 36 and non-insulin-dependent diabetes n = 64) were assessed using a self-report measure of quality of life, a symptom checklist and a questionnaire measure of anxiety and depression. In addition, they were independently rated for their level of physical impairment. The results showed that depression and, to a lesser extent, anxiety were significantly related to self-reported quality of life even when the differences in physical health and age were controlled for statistically. This study shows that, independent of the level of physical illness, affect, particularly depressive affect, is an important factor in the determination of quality of life.
尽管生活质量评估在医学领域被广泛应用，但对于做出这些判断所涉及的心理过程却知之甚少。已知的是，生活质量判断与健康状况的客观指标或临床医生的评级并非直接相关。特别是，患者的情感似乎与生活质量评级有关，但这种关系是否继发于身体健康仍存在争议。本研究的目的是确定焦虑和抑郁在一组糖尿病患者生活质量报告中的作用。使用生活质量的自我报告量表、症状清单以及焦虑和抑郁的问卷调查量表，对连续的100名糖尿病患者（胰岛素依赖型糖尿病n = 36，非胰岛素依赖型糖尿病n = 64）进行了评估。此外，他们的身体损伤程度由他人独立评级。结果表明，即使在对身体健康和年龄差异进行统计学控制后，抑郁以及程度较轻的焦虑与自我报告的生活质量仍显著相关。这项研究表明，不考虑身体疾病的程度，情感，尤其是抑郁情感，是决定生活质量的一个重要因素。
