ABSTRACT

Though correspondence across the affective experience and physiologic arousal levels of the stress response is thought to support efficacious coping and buffer against internalizing problems, little evidence has demonstrated such correspondence. Using a community sample of preadolescents (N=151, Mage=10.33 years, Minage=8.92, Maxage=12.00, 51.7% male), this person-centered study examined internalizing problem and coping-linked variability in psychobiological stress response correspondence. Preadolescents were exposed to the Trier Social Stress Test and self-reported negative affect (NA) and salivary cortisol (SC) levels were assessed. Multitrajectory modeling revealed four subgroups. Relative to In-Touch (i.e., Moderate NA–Moderate SC; n=65), Unmindful (i.e., Moderate NA–Low SC; n=49) were more likely to present with parent-reported but not self-reported internalizing problems; Vigilant (i.e., High NA–Low SC; n=13) were more likely to present with self- and parent-reported internalizing problems, less likely to use engagement coping, and more likely to use wishful thinking (e.g., “I wish problems would just go away.”); Denial (i.e., Low NA–High SC; n=24) self-reported similarly low internalizing problems, but were also more likely to report reliance on denial (e.g., “I pretend problems don’t exist.”). Findings illustrate meaningful heterogeneity in preadolescent psychobiological correspondence with implications for multimodal assessment and outcome monitoring in coping-based preventative interventions.

摘要

尽管压力反应的情感体验和生理唤醒水平之间的对应关系被认为支持有效应对和缓冲内化问题，但很少有证据证明这种对应关系。这项以人为中心的研究使用青春期前青少年的社区样本（N = 151，Mage = 10.33岁，Minage = 8.92，Maxage = 12.00，51.7％男性），检查了心理生物压力反应对应中的内化问题和应对相关的变异性。青春期前的青少年接受了特里尔社会压力测试，并评估了自我报告的负面情绪（NA）和唾液皮质醇（SC）水平。多轨迹模型揭示了四个亚组。相对于 In-Touch（即，中度 NA–中度 SC；n=65），漫不经心（即，中度 NA–低 SC；n=49）更有可能出现父母报告的内化问题，而不是自我报告的内化问题；警惕性（即，高 NA – 低 SC；n=13）更有可能出现自我报告和父母报告的内化问题，不太可能使用参与应对，而更有可能使用一厢情愿的想法（例如，“我希望问题就会消失。”）；否认（即低NA-高SC；n=24）自我报告了类似的低内化问题，但也更有可能报告对否认的依赖（例如，“我假装问题不存在。”）。研究结果表明，青春期前的心理生物学对应关系存在有意义的异质性，对基于应对的预防性干预措施的多模式评估和结果监测具有影响。
