Longitudinal Changes in Insomnia, Sleep Continuity, and Sleep Timing During Residential Treatment for Eating Disorders: A Six-Month Observational Study

Background

Sleep disturbances are a clinically relevant and transdiagnostic dimension of eating disorders (EDs), particularly during adolescence and young adulthood. Although early improvements in insomnia severity during residential treatment have been described, the longitudinal trajectory of sleep disturbances, habitual sleep timing, and eating disorder psychopathology across a six-month residential stay has not been systematically characterised.
