Subjective life expectancy mediates the association between adverse childhood experiences and depression: A parallel process latent growth curve study.

OBJECTIVE: Adverse childhood experiences (ACEs) are associated with poor mental health outcomes, including depression in later life. Subjective life expectancy (SLE) may mediate the relationship between ACEs and depression. However, the longitudinal relationship between ACEs, SLE, and depression remains underexplored. METHOD: We used five waves of data from the China Health and Retirement Longitudinal Study and employed a parallel process latent growth curve model to examine the longitudinal relationships among ACEs, SLE, and depression. Mediation analyses confirmed that the SLE intercept significantly mediated the effects of ACEs on both the initial level and the longitudinal trajectory of depression. CONCLUSIONS: SLE plays a key mediating role between ACEs and depression, suggesting that interventions aimed at improving SLE may reduce the long-term psychological burden of ACEs on mental health in later life.
