The Effect of Pediatric Cancer on Identity in Young Adult Survivors: Results from Project REACH.

Purpose: Living through cancer can have a profound effect on identity. Among those treated for adult-onset cancer, identifying as a cancer survivor is common and has been linked to positive mental and physical health outcomes. Although childhood is a critical period for identity formation, comparatively less is known about identity development after pediatric cancers. Methods: One hundred seventy young adults previously treated for pediatric cancer enrolled in Project REACH, a prospective cohort study, and completed self-report measures on effect of cancer on identity (e.g., cancer victim and survivor identity), frequency of thoughts of cancer, health outcomes (i.e., anxiety, depression, and health-related quality of life), and health behaviors (i.e., smoking, sun protection, exercise, and binge drinking). Results: The majority of participants identified as a survivor (n = 146, 85.9%), and survivor identity was linked to significantly higher anxiety (p = 0.01) and worse overall mental health (p = 0.04), but no other health outcomes or behaviors. Only 14 participants (8.2%) endorsed the victim identity, and they were significantly more likely to report binge drinking (p = 0.03) and worse overall mental health (p = 0.02) than nonvictims. Frequency of thoughts of cancer and effect of cancer on identity were also significantly associated with health outcomes (e.g., more frequent thoughts associated with higher anxiety). Conclusions: Our findings suggest that what is known about the relationship between identity and health outcomes after adult-onset cancer cannot be generalized to pediatric cancers, and that clinicians should not assume survivor identity is associated with better health outcomes in this group.
