Recent studies have indicated that CM (child maltreatment) may influence individuals' perception of their bodies, often resulting in a posttraumatic orientation to bodily signals (OBS). Given the intricate relationship between bodily and interpersonal experiences, it is hypothesized that posttraumatic OBS may be intergenerationally transmitted. However, knowledge regarding this phenomenon, and its underlying mechanisms, remains limited. Two studies tested (a) the link between CM and posttraumatic OBS, mediated by posttraumatic stress (PTS) symptoms and attachment security, and (b) the intergenerational transmission of a posttraumatic OBS following CM among dyads of parents and their young adult offspring. The first study included 445 young adults (mean age = 352, SD = 10.2), and the second study included 393 dyads (parents’ mean age = 58, SD = 5.91; offspring's mean age = 27, SD = 3.91). The participants completed self-reported questionnaires. Study 1 found that posttraumatic OBS was associated with CM, through the mediation of PTS symptoms (indirect effect = 0.15, p = .005), and insecure attachment (indirect effects between 0.132 and 1.44, p < .006). The second study found two pathways of intergenerational transmission. The first pathway showed indirect paths between parents’ CM exposure and offspring’s posttraumatic OBS, through parents’ reaction to CM (PTS symptoms, anxious attachment, and avoidant attachment) and posttraumatic OBS (indirect effects between 0.006 and 0.013, p < .039). The second pathway revealed indirect links between parents’ CM exposure and offspring’s posttraumatic OBS, through parents’ and offspring’s reaction to CM (indirect effects between 0.006 and 0.56, p < .015). The study’s findings add empirical evidence that posttraumatic OBS is a significant implication of CM. The second study illuminates the intergenerational transmission of a posttraumatic OBS following parental CM exposure, uncovering PTS symptoms, and insecure attachment styles as potential underlying mechanisms.

儿童虐待后创伤后取向身体信号的代际传递


最近的研究表明，CM（儿童虐待）可能会影响个人对自己身体的感知，通常会导致创伤后对身体信号 （OBS） 的定向。鉴于身体和人际经历之间的复杂关系，假设创伤后 OBS 可能是代际传播的。然而，关于这种现象及其潜在机制的知识仍然有限。两项研究测试了 （a） 由创伤后应激 （PTS） 症状和依恋安全介导的 CM 与创伤后 OBS 之间的联系，以及 （b） CM 后创伤后 OBS 在父母及其年轻成年后代之间的代际传递。第一项研究包括 445 名年轻人 （平均年龄 = 352，SD = 10.2），第二项研究包括 393 对 （父母的平均年龄 = 58，SD = 5.91;后代的平均年龄 = 27，SD = 3.91）。参与者完成了自我报告的问卷。研究 1 发现，创伤后 OBS 与 CM 相关，通过 PTS 症状（间接影响 = 0.15，p = .005）和不安全依恋（间接影响在 0.132 和 1.44 之间，p < .006）的介导。第二项研究发现了两种代际传播途径。第一个途径通过父母对 CM 的反应（PTS 症状、焦虑依恋和回避型依恋）和创伤后 OBS（间接效应在 0.006 和 0.013 之间，p < .039）显示了父母的 CM 暴露和后代的创伤后 OBS 之间的间接路径。第二条途径通过父母和后代对 CM 的反应揭示了父母的 CM 暴露与后代的创伤后 OBS 之间的间接联系（间接效应在 0.006 和 0.56 之间，p < .015）。 该研究的结果增加了经验证据，表明创伤后 OBS 是 CM 的重要影响。第二项研究阐明了父母暴露于 CM 后创伤后 OBS 的代际传播，揭示了 PTS 症状和不安全的依恋类型作为潜在的潜在机制。
