This daily diary study of individuals with fibromyalgia (FM) examined whether morning increases in loneliness relate to worsened evening bodily pain through afternoon negative pain cognitions.
220 participants with FM completed electronic diaries 4 times a day for 21days to assess loneliness, negative pain cognitions, bodily pain, and social enjoyment. Multilevel structural equation modeling was used to examine within-person relations of morning increases in loneliness, afternoon negative pain cognitions, and evening pain, controlling for morning pain.
On mornings when individuals experienced higher than their usual levels of loneliness, they experienced higher levels of afternoon maladaptive pain cognitions, which in turn predicted increases in evening pain above the level of morning pain. Afternoon maladaptive pain cognitions fully mediated the relations between morning loneliness and evening pain.
Lonely episodes are associated with subsequent increases in negative patterns of thinking about pain, which in turn predict subsequent increases in bodily pain within a day. Because pain cognitions mediate the loneliness-pain link, FM interventions may benefit from addressing individuals' vulnerability to maladaptive cognitions following lonely episodes.
这项针对纤维肌痛（FM）患者的日常日记研究，探讨了早晨孤独感的增加是否通过下午的负面疼痛认知导致晚上身体疼痛加剧。
220名FM患者连续21天每天4次完成电子日记，以评估孤独感、负面疼痛认知、身体疼痛和社交愉悦感。采用多水平结构方程模型，在控制早晨疼痛的情况下，研究孤独感的早晨增加、下午负面疼痛认知和晚上疼痛之间的个体内关系。
当个体在早晨经历高于其平常水平的孤独感时，他们在下午会经历更高水平的适应不良性疼痛认知，进而预测晚上疼痛会比早晨疼痛水平有所增加。下午适应不良性疼痛认知完全介导了早晨孤独感与晚上疼痛之间的关系。
孤独发作与随后疼痛负面思维模式的增加有关，进而预测一天内身体疼痛的随后增加。由于疼痛认知介导了孤独感与疼痛之间的联系，FM干预措施可能会受益于解决个体在孤独发作后对适应不良认知的易感性问题。
