Experiencing adversity in childhood is associated with increased risk of a range of psychopathologies, including depression and anxiety disorders. However, there is limited understanding of psychological mechanisms that may help to explain these relationships. The Identity Disruption Model proposes that early adversity can disrupt typical identity development, which may then increase one's vulnerability to psychopathology. The present study aims to apply the Identity Disruption Model to understanding symptoms of depression, generalized anxiety disorder, obsessive-compulsive disorder (OCD), and social anxiety.
A non-clinical sample of adults from the United States (n = 382) completed an online survey assessing early adversity, self-concept clarity, intolerance of uncertainty, and depression, generalized anxiety, OCD, and social anxiety symptoms. Structural equation models: (1) tested whether early adversity predicts psychopathology via a disrupted sense of self, and (2) explored the role of intolerance of uncertainty in the relationship between early adversity and psychopathology.
Early adversity predicted more severe symptoms of depression and anxiety via lower self-concept clarity. Furthermore, a parallel mediation model showed that self-concept clarity and intolerance of uncertainty simultaneously mediated the relationship between early adversity and psychopathology.
The data are cross-sectional in nature and longitudinal research is needed to more conclusively test the causal pathways.
Disrupted identity may be one mechanism through which childhood adversity predicts depression and anxiety disorder symptoms later in life. The Identity Disruption Model provides new avenues for future research and suggests potential points of early intervention for the prevention of depression and anxiety disorders.
儿童时期经历逆境与一系列精神病理学风险增加有关，包括抑郁和焦虑障碍。然而，对于可能有助于解释这些关系的心理机制，人们的理解有限。身份破坏模型提出，早期逆境会破坏典型的身份发展，从而增加个体患精神病理学的脆弱性。本研究旨在应用身份破坏模型来理解抑郁、广泛性焦虑症、强迫症（OCD）和社交焦虑的症状。
来自美国的非临床成年样本（n=382）完成了一项在线调查，评估了早期逆境、自我概念清晰度、不确定性容忍度以及抑郁、广泛性焦虑、OCD 和社交焦虑症状。结构方程模型：（1）检验早期逆境是否通过自我意识的破坏来预测精神病理学；（2）探讨不确定性容忍度在早期逆境与精神病理学之间的关系中的作用。
早期逆境通过自我概念清晰度降低预测了更严重的抑郁和焦虑症状。此外，平行中介模型表明，自我概念清晰度和不确定性容忍度同时中介了早期逆境与精神病理学之间的关系。
数据具有横断面性质，需要进行纵向研究才能更明确地检验因果途径。
身份破坏可能是儿童时期逆境预测成年后抑郁和焦虑障碍症状的一种机制。身份破坏模型为未来的研究提供了新的途径，并为预防抑郁和焦虑障碍提供了潜在的早期干预点。
