This systematic review found that psychosocial interventions had significant improvement on quality of life and depression symptoms among caregivers of advanced cancer patients, but not on anxiety symptoms, with non-significant effects at follow-up assessments. The overall quality of evidence was rated very low, and caution is needed when interpreting the results. Future randomized control trials with lower risk of bias, larger sample size, detailed participant characteristics, and informative interventions are desirable.
Purpose This systematic review aimed to synthesize the effectiveness of psychosocial interventions on caregivers of advanced cancer patients, in comparison with usual care, on caregivers' quality of life (QoL), anxiety, and depression symptoms. Methods Comprehensive searches for published and unpublished studies were performed using nine electronic databases, two trial registers, and reference lists of included studies. Two reviewers independently screened, appraised, and extracted data. The Cochrane risk of bias tool was used to appraise the methodological quality of included studies, while the Cochrane data extraction tool was used to elicit relevant information. Meta-analysis, narrative analysis, and sensitivity analysis were conducted to synthesize data. Standardized mean differences (SMD) represented effects of psychosocial interventions. Results Fifteen randomized controlled trials were included in this review. At post-intervention, findings revealed a significant small pooled effect size (SMD = 0.45) on QoL and significant moderate effect on depression (SMD = - 0.65). However, a small non-significant pooled effect size was observed on anxiety (SMD = - 0.24). At follow-up assessments, effect sizes of all outcomes were small and non-significant. Overall quality of evidence was rated very low for all outcomes and most studies had unclear or high risk of bias. Thus, results should be interpreted with caution. Conclusion Psychosocial interventions were effective in improving QoL and depression among caregivers of persons with advanced cancer. However, future randomized control trials with lower risk of bias, larger sample size, detailed participant characteristics, and informative interventions are desirable.
