The study addressed the dose-response model in the association of cumulative adversity with mental health.
Data of 1,725 participants aged 50+ were drawn from the Israeli component of the Survey of Health, Ageing, and Retirement in Europe. Measures included an inventory of potentially traumatic events, distress (lifetime depression, depressive symptoms), and well-being (quality of life, optimism/hope).
The maximal effect of cumulative trauma emerged in the contrast between 0-2 and 3+ events, where the higher number of events related to higher distress but also to higher well-being. While self-oriented adversity revealed no, or negative, association with well-being, other-oriented adversity revealed a positive association.
The study suggests an experiential dose of cumulative adversity leading to a co-activation of distress and well-being. The source of this co-activation seems to be other-oriented adversity.
本研究探讨了累积逆境与心理健康之间关联的剂量反应模型。
数据来自欧洲健康、衰老和退休调查的以色列部分，共纳入 1725 名 50 岁以上的参与者。测量工具包括潜在创伤性事件清单、痛苦（终生抑郁、抑郁症状）和幸福感（生活质量、乐观/希望）。
在 0-2 项和 3+项事件之间的对比中，累积创伤的最大效应出现，表明事件数量越多，痛苦程度越高，但幸福感也越高。虽然以自我为导向的逆境与幸福感没有关联，或者呈负相关，但是以他人为导向的逆境与幸福感呈正相关。
该研究表明，累积逆境的体验剂量会导致痛苦和幸福感的共同激活。这种共同激活的来源似乎是他人导向的逆境。
