INTRODUCTION Research is needed to determine mechanisms of effect linking family relationships and chronic pain for adults. Guided by the Biobehavioral Family Model (BBFM), the present study examined indirect effects between a negative family emotional climate and chronic pain disease activity, as mediated by biobehavioral reactivity. METHOD Data for this study are from the Midlife Development in the United States; specifically, a subsample of participants who reported experiencing chronic pain (n = 1,461, ages 32-84). Participants self-reported family strain, biobehavioral reactivity (i.e., anxiety, depression), and chronic pain disease activity (i.e., pain interference, global health). A subsample of participants (n = 1,070) completed an intimate partner strain measure, indicating they were married/in a committed relationship. Structural equation models were tested with maximum likelihood estimation and bootstrapping. RESULTS Family strain was indirectly associated with chronic pain disease activity via biobehavioral reactivity-Model 1; χ²(10) = 40.75, p < .000, root mean square error of approximation [RMSEA] = .07, comparative fit index [CFI] = .96, standardized root-mean-square residual [SRMR] = .04; partial mediation occurred for partnered participants. This finding was replicated when modeling family strain simultaneously with intimate partner strain, though intimate partner strain was not associated with chronic pain disease activity-Model 2; χ²(5) = 8.29, p = .14, RMSEA = .03, CFI = .99, SRMR = .01. DISCUSSION These findings add to the growing literature that emphasizes the role of family relationships in chronic pain. Future research is needed to replicate our use of the BBFM to specify pathways of effect, incorporating relational and observational data, with diverse samples.

将家庭和亲密伴侣关系与慢性疼痛联系起来：生物行为家庭模型的一种应用。

引言需要进行研究以确定将家庭关系与成年人慢性疼痛联系起来的作用机理。在生物行为家庭模型（BBFM）的指导下，本研究研究了负面的家庭情感气候和慢性疼痛疾病活动之间的间接影响，这种间接影响是由生物行为反应性介导的。方法：这项研究的数据来自美国中年发展计划。具体来说，是一份报告称遭受慢性疼痛的参与者的子样本（n = 1,461，年龄在32-84岁之间）。参与者自我报告家庭压力，生物行为反应（即焦虑，抑郁）和慢性疼痛疾病活动（即疼痛干预，全球健康）。参与者的一个子样本（n = 1,070）完成了一项亲密伴侣压力测试，表明他们已婚/有固定的关系。用最大似然估计和自举测试了结构方程模型。结果家庭菌株通过生物行为反应模型1与慢性疼痛疾病的活动间接相关。χ2（10）= 40.75，p <.000，近似均方根误差[RMSEA] = .07，比较拟合指数[CFI] = 0.96，标准均方根残差[SRMR] = .04；合作伙伴进行了部分调解。当对家庭菌株和亲密伴侣菌株同时进行建模时，重复了这一发现，尽管亲密伴侣菌株与慢性疼痛疾病的活动无关（模型2）。χ2（5）= 8.29，p = .14，RMSEA = .03，CFI = .99，SRMR = .01。讨论这些发现增加了越来越多的文献，这些文献强调家庭关系在慢性疼痛中的作用。需要进行进一步的研究来复制我们对BBFM的使用，以指定影响途径，并结合各种样本的相关数据和观察数据。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
