BACKGROUND In the literature, depression and alexithymia are associated with greater pain perception. It is unknown whether depression and alexithymia have additive effects on perceived pain. METHODS The present study examined 152 participants (96 women, 56 men). Participants completed the 20-item Toronto Alexithymia Scale, the Hamilton Depression Rating Scale, the Brief Pain Inventory, and the NEO Personality Inventory. There were 49 participants in the active phase of depression with either definite (n = 15) or no alexithymia (n = 34). One hundred three participants showed no depression with either definite (n = 14) or no alexithymia (n = 89). RESULTS Pain severity showed a small but significant relationship with alexithymia and depression. Pain was greater among without alexithymia individuals who were depressed and among with alexithymia individuals who were not depressed. Individuals with combined presence of depression and alexithymia did not report greater pain than participants with either condition alone. Alexithymia, depression, and pain were significantly correlated with greater neuroticism. CONCLUSIONS We did not find a summative effect of depression and alexithymia on perceived pain. One interpretation of this result is that neuroticism (a shared personality factor in both depression and alexithymia) may be partially responsible for the effect on pain.

抑郁时感到身体疼痛：述情障碍的影响

背景在文献中，抑郁和述情障碍与更大的痛觉有关。目前尚不清楚抑郁症和述情障碍是否对感知疼痛有累加作用。方法 本研究调查了 152 名参与者（96 名女性，56 名男性）。参与者完成了 20 项多伦多述情障碍量表、汉密尔顿抑郁量表、短暂疼痛量表和 NEO 人格量表。有 49 名参与者处于抑郁的活跃期，有明确的（n = 15）或无述情障碍（n = 34）。103 名参与者没有表现出明确的抑郁症（n = 14）或无述情障碍（n = 89）。结果 疼痛的严重程度与述情障碍和抑郁症之间存在微小但显着的关系。没有述情障碍的抑郁症患者和没有抑郁症的述情障碍患者疼痛更严重。与单独患有抑郁症和述情障碍的参与者相比，同时存在抑郁症和述情障碍的个体并没有报告更大的疼痛。述情障碍、抑郁和疼痛与更严重的神经质显着相关。结论 我们没有发现抑郁症和述情障碍对感知疼痛的总结性影响。对这一结果的一种解释是，神经质（抑郁症和述情障碍的共同人格因素）可能是导致疼痛的部分原因。和疼痛与更严重的神经质显着相关。结论 我们没有发现抑郁症和述情障碍对感知疼痛的总结性影响。对这一结果的一种解释是，神经质（抑郁症和述情障碍的共同人格因素）可能是导致疼痛的部分原因。和疼痛与更严重的神经质显着相关。结论 我们没有发现抑郁症和述情障碍对感知疼痛的总结性影响。对这一结果的一种解释是，神经质（抑郁症和述情障碍的共同人格因素）可能是导致疼痛的部分原因。
