The Efficacy of Nurse-Delivered Psychosocial and Psychotherapeutic Interventions for Individuals With Mental Health Issues: A Meta-Analysis of Randomised Controlled Trials

Background: Nurses are among the most interactive professionals in society, providing both care and psychosocial and psychotherapeutic interventions for individuals with mental health issues. Nurse-centred approaches have demonstrated a positive impact on addressing mental health issues. Aim: This study aimed to evaluate the effectiveness of psychosocial and psychotherapeutic interventions administered by nurses in managing mental health issues. Methods: For this meta-analysis, data were gathered through a comprehensive search of databases, including PubMed, Web of Science, EBSCOhost, Google Scholar and the YÖK Thesis Center, with no restrictions on publication year. Following the review process, a total of 25 studies were included in the analysis. The PRISMA checklist was employed to guide our study. Results: The meta-analysis revealed that interventions implemented by nurses in the context of mental health were effective. Specifically, the psychosocial and psychotherapeutic interventions significantly reduced depression levels in individuals (SMD: −0.918, 95% CI: −1.350 to −0.486; Z = −4.161; p < 0.05) and anxiety levels (SMD: −0.61, 95% CI: −1.190 to −0.029; Z = −2.59; p < 0.05). Additionally, these interventions were associated with an improvement in individuals' quality of life (SMD: 0.673, 95% CI: 0.303–1.403; Z = 3.56; p < 0.05). Conclusion: Nurses can play a pivotal role in addressing mental health issues, effectively contributing to the reduction of anxiety and depression levels while enhancing the overall quality of life for individuals.
