Abstract：
Findings have revealed a strong link between exposure to child maltreatment (CM) and later chronic pain. Concurrently, other findings have been grounded in the understanding that CM consequences may not end with the exposed individual, rather, they extend to their offspring. However, little is known regarding the possible intergenerational transmission of chronic pain following CM. This study examines whether chronic pain among parents and their young adult offspring may be associated with parental exposure to CM. Three hundred ninety-three parent-offspring dyads (parents\' mean age = 58, SD = 5.91 years; offspring\'s mean age = 27, SD = 3.91 years) completed self-report questionnaires, assessing CM (CTQ), posttraumatic stress (PTS) and disturbances in self-organisation (DSO) symptoms (ITQ), and chronic pain. CM was associated with chronic pain mediated by DSO symptoms among parents (indirect effect = 0.77; p = 0.007) and PTS symptoms among offspring (indirect effect = 0.285; p = 0.005). Offspring chronic pain was significantly associated with parental CM through two intergenerational paths: the mediation of parents\' DSO symptoms and chronic pain (indirect effect = 0.298; p = 0.011), and through parents\' PTS symptoms and offspring\'s PTS symptoms (indirect effect = 0.077; p = 0.004). This study\'s findings support the relevance of the intergenerational transmission of chronic pain following parental exposure to CM. Furthermore, the findings reveal complex PTS symptoms as a possible underlying mechanism for the intergenerational associations of chronic pain following CM.
摘要：
研究结果表明，暴露于儿童虐待（CM）与后来的慢性疼痛之间存在很强的联系。同时,其他发现已经基于这样的理解，即CM后果可能不会随着暴露的个体而结束，更确切地说,他们延伸到他们的后代。然而,关于CM后慢性疼痛的可能代际传播知之甚少。这项研究调查了父母及其年轻成年后代的慢性疼痛是否与父母暴露于CM有关。三百九十三对亲子关系（父母的平均年龄=58，SD=5.91岁；后代的平均年龄=27，SD=3.91岁）完成了自我报告问卷，评估CM（CTQ），创伤后应激（PTS）和自我组织障碍（DSO）症状（ITQ），和慢性疼痛。CM与父母中DSO症状介导的慢性疼痛相关（间接效应=0.77；p=0.007），后代中PTS症状相关（间接效应=0.285；p=0.005）。子代慢性疼痛与父母CM通过两个代际路径显著相关：父母DSO症状和慢性疼痛的调解（间接效应=0.298；p=0.011），并通过父母的PTS症状和后代的PTS症状（间接效应=0.077；p=0.004）。这项研究的发现支持父母接触CM后慢性疼痛代际传播的相关性。此外，这些发现揭示了复杂的PTS症状可能是CM后慢性疼痛代际关联的潜在机制。
