PSQI = Pittsburgh Sleep Quality Index; REM = rapid eye movement.
a
Preoccupied or fearful-avoidant versus secure or dismissing-avoidant. All analyses statistically adjusted for age, baseline depressive symptoms, and length of time between psychosocial assessment and PSG. Analyses and significance levels are based on b log-transformed or c square-root transformed data, respectively.
