Note: b = unstandardized regression coefficient. β = standardized regression coefficient. p = statistical significance. PSAS-C = presleep arousal scale, cognitive factor. PSAS-S = presleep arousal scale, somatic factor. Sleep latency = minutes from lights out to first epoch of sleep. Wake after sleep onset = minutes awake post sleep onset. Δ Sleep latency = Change in PSG-based sleep latency from pre to posttreatment. Δ Wake after sleep onset = Change in PSG-based wake after sleep onset from pre to posttreatment. Δ PSAS-C = Change in presleep arousal scale cognitive factor scores from pre to posttreatment. Δ PSAS-S = Change in presleep arousal scale somatic Factor scores from pre to posttreatment.
