Purpose: This study aimed to examine the effect of acupressure on sleep initiation and maintenance disorders amongnurses working rotating shift work schedule. Method: In this randomized controlled trial, 62 shift-working nurses withself-reported insomnia were randomly assigned to either an experimental group (n=31) receiving auricular acupressureor a control group (n=31) receiving sleep hygiene education. The intervention lasted two weeks. The Pittsburgh SleepQuality Index (PSQI) was administered at baseline, Week 1, and Week 2; insomnia severity was measured using a NumericRating Scale; and depression was assessed with the Patient Health Questionnaire-9. Stress was identified as a covariateand controlled for in repeated-measures ANCOVA. Results: After adjusting for baseline stress, the experimental groupshowed a significantly greater reduction in insomnia severity compared to the control group (F=4.53, p=.013). Althoughthere was no significant difference between groups in total PSQI scores (p>.05), the experimental group demonstratedsignificant improvements in sleep latency (PSQI item 5a, F=6.41, p=.002) and subjective sleep quality (PSQI item 6, F=5.84,p=.004). Minor adverse effects did not result in withdrawal from the study. Conclusion: Acupressure may be an effectiveadjunct intervention for reducing insomnia severity and improving certain aspects of sleep initiation and maintenancedisorders in nurses working a rotating shift work schedule. Further research is recommended to investigate its long-termefficacy, optimal acupressure points, and applicability in various clinical settings.
