In this study, we examined the overlap between pain and depression in a sample of 342 chronic pain patients treated at a specialty pain clinic. Confirmatory factor analysis was conducted to test the differentiation of pain and depression measured as latent factors derived from the subscales of the Short Form McGill Pain Questionnaire and the Center for Epidemiological Studies Depression Scale. The affective pain subscale did not load on latent depression and the somatic depression subscale loaded weakly on latent pain. Although pain and depression are linked, we found that affective pain is distinct from depression, and that somatic depression is distinct from pain. This finding justifies further examination of the casual relationship between pain and depression.
在这项研究中，我们调查了在一家专科疼痛诊所接受治疗的 342 名慢性疼痛患者样本中疼痛和抑郁之间的重叠。进行验证性因子分析以检验疼痛和抑郁的区分，其被测量为来自 Short Form McGill Pain Questionnaire 和 Center for Epidemiological Studies Depression Scale 分量表的潜在因素。情感性疼痛分量表未加载到潜在的抑郁上，而躯体性抑郁分量表弱加载到潜在的疼痛上。尽管疼痛和抑郁相关，但我们发现情感性疼痛与抑郁不同，躯体性抑郁与疼痛不同。这一发现证明了进一步研究疼痛和抑郁之间的因果关系是合理的。
