Posttraumatic growth in colorectal cancer survivors: A systematic review.

OBJECTIVE

The diagnosis of cancer is an adverse event; nevertheless, it can also exert positive changes on survivors, such as posttraumatic growth (PTG). This review aims to integrate researches on PTG in colorectal cancer (CRC) survivors, including manifestations and prevalence of PTG, factors associated with PTG and interventions on PTG.

METHODS

A systematic search was implemented on six databases to identify studies on PTG in CRC survivors published in English or Chinese from October 1995 to May 2022. We also performed a manual search for additional studies from the article reference lists.

RESULTS

Thirty-one studies were included. The results were integrated based on the PTG theoretical framework and PTG affective-cognitive processing model. PTG manifests in CRC survivor-caregiver dyads in five domains, including personal growth, appreciation of life, relating to others, new possibilities and spiritual change. Factors correlated with PTG can be integrated into levels of personality, event cognitions, appraisal mechanisms, emotional states, coping and social environmental context. Elements of interventions can be integrated according to the affective-cognitive processing PTG model. Existing interventions are effective in promoting PTG in CRC survivors.

CONCLUSION

We provide a systematic perspective on studies targeting PTG in CRC survivors. PTG manifested in survivor-caregiver dyads. Factors associated with PTG in CRC survivors are significant, and the interventions are effective. An intervention programme based on the affective-cognitive processing model and focused on CRC survivor-caregiver dyads would be significant for the dyads facing cancer.
