Effectiveness of Cognitive Behavioral Therapy in Reducing Psychological Distress in Nurses: A Systematic Review and Meta-Analysis of Experimental Studies

Work-related stress, a major contributor to physical and mental health issues of nurses, has a direct impact on patient safety and nurses' well-being. However, few studies have investigated the effectiveness of cognitive behavioral therapy in reducing psychological distress in nurses. Systematic search of six databases including CINAHL Plus with Full Text, Cochrane Library, Embase, Medline, PubMed, and Web of Science from their inception to February 27, 2024. The primary outcomes assessed were reductions in stress, anxiety, and depression following the implementation of cognitive behavioral therapy. A random effects model, accounting for study differences, was applied in the meta-analyses. Egger's regression test was utilized to assess potential publication bias in the pooled analyses. The meta-analysis included 10 studies that demonstrated the intervention's beneficial effects in reducing stress, anxiety, and depression among nurses. Despite the positive effects observed with cognitive behavioral therapy (CBT) in alleviating psychological distress among nurses, the generalizability of these findings may require further confirmation due to the diversity of cognitive behavioral therapies.
