Relationship between childhood trauma and sleep disturbances: the role of perceived stress as a mediator

Abstract

The main objective of the current study was to analyze the mediating role of perceived stress on the relationship between childhood trauma and sleep disturbances among the adult population. The sample of this cross-sectional study was composed of 987 Portuguese adults with sleep disturbances, who completed a self-administered questionnaire about childhood trauma, sleep disturbances, and perceived stress. The results of analyses found that in the model that included the variables childhood trauma and perceived stress, both variables were predictors of sleep disturbances; however, perceived stress was the strongest predictor. Regarding the model with the subtypes of maltreatment, only Emotional Abuse predicted sleep problems. Results of the Path Analysis model showed that perceived stress partly mediates the effect of childhood trauma on adult sleep disturbances. This study has clinical implications, supporting the importance of taking into account childhood trauma and perceived stress during the assessment and intervention of sleep disturbances.
