Effect of Psychosocial Interventions on Cancer's Caregiver Quality of Life: Meta-analysis

Background: People living with cancer benefit greatly from informal caregivers. No previous meta-analysis was done to check the effect of psychological intervention on cancer caregiver's quality of life. Objectives: The goal of this meta-analysis was to check the effect of psychosocial interventions on Cancer's Caregiver quality of life and check the impact of various psychological intervention programs. Methods: A comprehensive literature search was conducted from January 2006 to April 2021 using PubMed, PubMed Central, Clinical Key, CINAHL Database, EBSCO, Google Scholar and Cochrane database. Results: The effect of psychological intervention programs on caregiver's quality of life was evaluated using a mean difference between experimental and control groups. A random-effects model was used to measure the mean difference (MD) for calculating the cancer caregiver's quality of life. The final report comprised eight trials with a total of 1142 participants. The caregiver intervention programme was found to improve cancer caregivers' quality of life, but not statistically significantly (mean difference=0.10; p<0.00001). Conclusion: According to this meta-analysis, The psychological intervention program positively affected cancer caregiver's quality of life. Further randomised controlled trials are required to prove that psychological interventional programs are successful strategies for improving cancer caregiver's quality of life.
