Introduction: Shift-working nurses are at high risk of developing insomnia. However, few interventions have targeted Shift Work Tolerance (SWT) as a strategy to alleviate insomnia among shift-working nurses. Objectives: This study aimed to evaluate the effectiveness of SWT intervention in reducing insomnia symptoms among female shift-working nurses. Methods: A quasi-experimental pre-post-test control group design was conducted with 30 participants, who were assigned to intervention (n=15) and control (n=15) groups. The SWT program addressed circadian rhythm of sleep, sleep hygiene, occupational stressors, and coping strategies as well as stress management. Insomnia was assessed using the Regensburg Insomnia Scale (RIS) at baseline and one month after intervention. Data were analyzed using Wilcoxon and Mann–Whitney tests. Results: The intervention group showed significant improvements in insomnia outcomes, including reduced sleep latency, increased sleep duration and continuity, fewer sleepless nights, reduced fear of insomnia, and reduced daytime impairment compared with the control group (p < 0.05). The overall insomnia scores significantly decreased in the intervention group (Δ = 4.93, p = 0.001) but not in the control group (Δ = 2.21, p > 0.05). Conclusion: The SWT intervention was effective in reducing insomnia symptoms and improving sleep health among shift-working nurses. This approach may serve as a feasible strategy to enhance well-being and job performance in clinical practice.
