Abstract
This pilot study evaluated a home-based cognitive-behavioral intervention—the Sleep Enhancement Training System for Shift Workers (SETS-SW)—in a sample of 21 nurses working night shifts. Participants (20 women and 1 man) received 2 home-based cognitive-behavioral interventions: a 4-week active control intervention, followed by the 4-week SETS-SW intervention. Sleep and circadian rhythms were assessed at baseline and after each intervention using questionnaires and 1 week of wrist actigraphy. After the SETS-SW intervention, participants reported better sleep quality, although no change in actigraphy outcomes was observed. Over the course of the study, participants also reported improved wellbeing and less appetite disturbance. A home-based cognitive-behavioral intervention may be useful for managing effects of shift work, but needs further evaluation in larger samples.
