To date, the developmental trajectories of neuroticism, as well as the longitudinal interrelationship among neuroticism, depression, health, and childhood misfortune, have not been verified in a nationally representative U.S. sample. This study aims to determine the trajectories of neuroticism and examine how additive childhood misfortune affects the co-development of neuroticism and depression. Longitudinal data from 5,377 individuals who responded to the national survey of Midlife Development in the U.S. (MIDUS) were analyzed. The latent growth model (LGM) and latent growth class model (LGCA) were used to analyze the heterogeneity of individual growth trajectories of neuroticism. Bivariate latent growth models (BLGM) with both time-invariant and time-varying covariates were used to investigate the co-development of neuroticism and depression. The results of Manuscript 1 suggested that nearly half (49.3%) of participants were in the medium neuroticism class; however, a third of participants had low neuroticism across time (33.4%), and substantial minority course trajectories characterized by high neuroticism (17.3%). Robust predictors of membership in the low neuroticism class were gender, age, education, and self-rated financial situation. Individuals with more adverse experiences in childhood were more likely to have a trajectory characterized by medium and high neuroticism. The results of Manuscript 2 suggested that participants generally experienced decreases in neuroticism and depression, and trajectories of neuroticism and depression were closely related to each other. Additive childhood misfortune (ACM) predicted changes in both neuroticism and depression after controlling other covariates. Multimorbidity significantly predicted neuroticism and depression at each time point.
