The role of peer support in psychosocial outcomes among adolescent and young adult (AYA) cancer survivors.

Abstract

e22528 Background: Adolescents and young adults (AYA) who experienced cancer treatment sometimes show posttraumatic stress symptoms (PTSS) and yet report positive psychological changes, known as posttraumatic growth (PTG). Literature suggests PTSS and PTG are not on opposite ends of a single spectrum but rather coexist. It is expected to have distinct relationships with social support, and yet, the roles of peer support remain unknown. This study examines PTG and PTSS, and their correlates with peer support among AYA cancer survivors. Methods: A cross-sectional study was conducted using a questionnaire survey with AYA cancer survivors. A total of 212 AYA survivors were recruited from 11 cancer centers and 12 cancer patients’ communities. They completed a self-report measure of the PTG Inventory and the Impact of Event Scale revised (IES-R) to assess PTSS. Diagnosis, treatment, peer support (i.e., affiliation to AYA patients’ community and friendship with other AYA cancer patients), and social status information was also collected from questionnaires. A series of multiple regression analyses was used to identify significant correlates among peer support, PTG and PTSS. Results: PTG and PTSS were not significantly correlated with each other, being consistent with the previous studies. PTG was positively associated with male gender, years since diagnosis, good communication with others, and friendship with other AYA cancer patients. Friendship with other AYA cancer patients was positively associated with not just the overall PTG but all five domains of PTG. PTSS was associated with years since diagnosis, unemployed status, and symptom of late effects. PTSS was, however, unlike PTG, not related with friendship with other AYA cancer patients or affiliation to AYA patients’ community. Conclusions: Good communication and friendship with other AYA cancer patients is suggested to play an important role in PTG but not PTSS. Psychosocial intervention to facilitate peer support among AYA cancer patients would possibly contribute to revive their lives through PTG. Future studies should further investigate what factors would contribute to alleviation of PTSS and foster PTG. Clinical trial information: UMIN000035439.
