Childhood maltreatment predicts poor sleep quality in Chinese adults: The influence of coping style tendencies

This longitudinal study assessed the prospective link between childhood maltreatment and sleep quality in adulthood, with a specific focus on examining whether different coping style tendencies influence these associations. The baseline sample included 1600 adult participants, with 1140 participants successfully followed up 5 years later. The key variables were measured using the Childhood Trauma Questionnaire (CTQ), Simplified Coping Style Questionnaire (SCSQ), and Pittsburgh Sleep Quality Index (PSQI). Generalized linear mixed models were employed to estimate unstandardized β estimates and 95 % confidence intervals (95%CIs). Structural equation modeling was used to test the mediation model. Individuals reported childhood maltreatment at baseline were at an increased risk for sleep disturbances at follow-up. Childhood maltreatment negatively predicted the baseline coping style tendency (β = −0.29, P
