Patients with chronic low-back pain are frequently diagnosed as depressed. However, many of the neurovegetative signs of depression may also result from pain. The purpose of the present study was 1) to investigate the relationship between commonly used measurements of depression and pain perception; and 2) to examine the utility of differentiating between somatic signs and cognitive/affective symptoms of depression in patients with chronic low-back pain. The Beck Depression Inventory and the Hamilton Psychiatric Rating Scale for Depression were divided into cognitive/affective and somatic subscales. These measures, as well as the Minnesota Multiphasic Personality Inventory, were administered to 111 patients with chronic low-back pain. Analyses revealed significant correlations between depression scores and self-reported pain intensity. The cognitive/affective subscale of the Beck Depression Inventory resulted in the only nonsignificant correlation with pain intensity. These findings suggest that commonly used measurements of depression are confounded with pain symptomatology and that the cognitive/affective category of the Beck Depression Inventory may prove to be a more accurate measurement of depression in patients with chronic low-back pain.
慢性下背痛患者常被诊断为患有抑郁症。然而，许多抑郁的神经植物性体征也可能由疼痛引起。本研究的目的是：1）调查常用的抑郁测量方法与疼痛感知之间的关系；2）检验区分慢性下背痛患者抑郁的躯体体征和认知/情感症状的效用。贝克抑郁量表和汉密尔顿抑郁量表被分为认知/情感和躯体分量表。这些测量方法，以及明尼苏达多相人格调查表，被应用于111名慢性下背痛患者。分析显示抑郁得分与自我报告的疼痛强度之间存在显著相关性。贝克抑郁量表的认知/情感分量表与疼痛强度的相关性是唯一不显著的。这些发现表明，常用的抑郁测量方法与疼痛症状相互混淆，贝克抑郁量表的认知/情感类别可能被证明是慢性下背痛患者抑郁的更准确测量方法。
