Background: The global nursing workforce is facing a significant shortage, compounded by excessive workloads and emotional strain. These challenges have led to increased attrition among clinical staff, posing critical threats to healthcare delivery. Interventions that are both time-efficient and effective are urgently needed to support nurses’ well-being and retention.
Objectives: This study aimed to evaluate the effectiveness of a brief Acceptance and Commitment Therapy (ACT) workshop, supplemented by LINE-based microlearning, in reducing nurses’ turnover intention and psychological distress (stress, anxiety, and depression), and in enhancing psychological flexibility.
Methods: A one-group pretest-posttest experimental design was adopted. Fifty-nine nurses participated in a 4-hour ACT workshop, followed by a four-week LINE-based microlearning intervention that delivered weekly ACT tips and biweekly 1-minute videos explaining core ACT principles. Outcomes were measured at three time points: before the workshop (T0), immediately after (T1), and one month later (T2). Generalized Estimating Equations (GEE) were used to analyze changes over time.
Results: The intervention significantly reduced stress, anxiety, depression, and turnover intention, with improvements observed both immediately post-intervention and sustained at the one-month follow-up compared to baseline (p < .05). The attrition rate was 3%. However, no statistically significant changes were found in psychological flexibility across time points.
Conclusion: A brief ACT workshop supplemented with LINE-based microlearning is a feasible and effective strategy to address psychological distress and turnover intention among nurses, particularly in contexts constrained by staffing shortages. Although psychological flexibility did not show significant improvement, the overall outcomes suggest this intervention may serve as a valuable, time-sensitive support tool in clinical settings. Further research is warranted to explore long-term effects and strategies to enhance psychological flexibility through extended or repeated interventions.
