Long-term effects of a tailored mindfulness-based program for Chinese intensive care unit nurses: A randomized parallel-group trial.

AIM: This study investigated the direct and long-term improvements that mindfulness-based interventions exert on intensive care unit nurses. We assessed an abbreviated four-week, twice-weekly mindfulness-based intervention program's effect on work-related mental health variables and examined whether the intervention impact was maintained at two- and six-month follow-up assessments. We also examined the training program's effects on work and life. BACKGROUND: Previous research has shown that mindfulness interventions exert positive effects immediately after treatment. However, few studies have examined whether treatment effects are maintained over time or under different circumstances. Moreover, treatment effects among Chinese intensive care unit nurses have rarely been examined. DESIGN: We conducted a randomized, non-blinded, parallel-group trial. METHODS: Participants included 90 intensive care unit nurses, divided into two cohorts, who participated in the program in October 2016 and April 2017. They completed validated measures of mindfulness, burnout syndromes, anxiety and depressive symptoms and well-being at baseline (T1), immediately after intervention (T2), two months after (T3) and six months after (T4) the intervention. RESULTS: We observed a significant group effect (1) immediately post-intervention and two months after intervention for mindfulness; (2) at two months after intervention for anxiety, depression and subjective well-being and (3) at post-intervention, two months after and six months after for emotional exhaustion. CONCLUSIONS: These findings suggest that the tailored four-week mindfulness-based intervention program improved intensive care unit nurses' mental health, although further research is needed to verify its feasibility in a clinical working environment.

Moderating Effect of Mindfulness on the Relationships Between Perceived Stress and Mental Health Outcomes Among Chinese Intensive Care Nurses.

This study aimed to explore the potential moderating effect of mindfulness and its facets on the relationships among perceived stress and mental health outcomes (burnout, depression, anxiety, and subjective well-being) among Chinese intensive care nurses. A total of 500 Chinese intensive care nurses completed self-report measures of mindfulness, burnout syndromes, perceived stress, depression, anxiety, and subjective well-being. Correlation and hierarchical multiple regressions were applied for data analysis. Mindfulness moderated the effects of perceived stress on emotional exhaustion (the core component of burnout syndrome), depression, anxiety, positive affect, and negative affect but not on the other two dimensions of burnout and life satisfaction. Further analyses indicated that the ability to act with awareness was particularly crucial in improving the effects of perceived stress on depression. These results further broaden our understanding of the relationships between perceived stress and burnout, depression, anxiety, and subjective well-being by demonstrating that mindfulness may serve as a protective factor that alleviates or eliminates the negative effects of perceived stress on depression, anxiety, burnout syndrome, and subjective well-being and may instigate further research into targeted mindfulness interventions for Chinese intensive care nurses.
