Purpose:
To evaluate the effectiveness of psychosocial interventions for posttraumatic growth in patients with cancer.
Method:
A systematic literature search was performed, and relevant studies published prior to January 8, 2020, were retrieved from MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trails, CINAHL, and PsycINFO. Two reviewers independently assessed the eligibility of each study and extracted the data. The Cochrane risk-of-bias tool was utilized to assess the quality of the studies. Review Manager (Version 5.3) was used to analyse the data. The posttraumatic growth scores were calculated using the standard mean difference (SMD) and 95% confidence intervals (CIs).
Results:
Fifteen randomized controlled trials published between 2000 and 2019 were included. Most of the studies had a moderate risk of bias due to low methodological quality. The meta-analysis indicated that the PTG scores in the experimental groups were higher than those in the control groups (SMD = 0.42, 95% CI: 0.26-0.57, P < 0.00001). The most effective and commonly used method was mindfulness-based interventions (SMD = 0.55, 95% CI: 0.15-0.95, P = 0.007). Subgroup analysis showed that the effects of psychosocial interventions on breast cancer patients are greater than the effects on other types of cancer patients (SMD = 0.72, 95% CI: 0.44-0.99, P < 0.00001).
Conclusion:
Psychosocial interventions for cancer patients are effective in facilitating posttraumatic growth. The most commonly used and effective methods are mindfulness-based interventions. More large well-designed randomized controlled trials are needed to identify the effectiveness of psychosocial interventions for posttraumatic growth in patients with cancer.
