Effect of Meaning-in-Life Interventions for Advanced Cancer Patients: A Systematic Review and Meta-Analysis.

This study aimed to explore the effects of meaning-in-life intervention on meaning in life, quality of life, spiritual well-being, anxiety, and depression in advanced cancer patients. Databases, including Ovid Medline, Cochrane, PsycINFO, CINAHL, and Embase, were searched to identify relevant randomized controlled trials based on predefined criteria. Seven studies were included. Meta-analysis was performed for five studies, involving 718 patients with advanced cancer. The meta-analysis revealed no significant effects of the meaning-in-life intervention on spiritual well-being, depression, and anxiety of advanced cancer patients. The insufficient number of studies and risk of bias limit the strength of the conclusions. Therefore, further studies with larger sample sizes and methodologically rigorous designs are required to evaluate the effects of meaning-in-life interventions for advanced cancer patients. Our findings can support a better understanding of the need to study meaning-in-life interventions in advanced cancer patients and foster sustained attention to recognize meaning-in-life interventions as an effective method in healthcare.
