The role of body image dissatisfaction in the association between treatment‐related scarring or disfigurement and psychological distress in adult survivors of childhood cancer

摘要

Abstract Objective To examine the potential mediating role of body image dissatisfaction on the association between treatment‐related scarring/disfigurement and psychological distress in adult survivors of childhood cancer. Methods Participants included 1714 adult survivors of childhood cancer (mean [SD] age at evaluation?=?32.4 [8.0] years, time since diagnosis?=?24.1 [8.1] years) enrolled in the St. Jude Lifetime Cohort Study. Survivors completed measures of body image, emotional distress, and posttraumatic stress symptoms (PTSS). Body image dissatisfaction (BID) was categorized into 2 groups (cancer‐related and general) based on factor analysis. Using causal mediation analysis, we estimated the proportion of psychological distress associated with treatment‐related scarring/disfigurement that could be eliminated by resolving BID through a hypothetical intervention. Results Among survivors with scarring/disfigurement of the head, a sizable proportion of the relative excess of psychological distress could be eliminated if BID was successfully treated (males: [cancer‐related BID: depression: 63%; anxiety: 100%; PTSS: 52%]; [general BID: depression: 70%; anxiety: 100%; PTSS: 42%]; females: [cancer‐related BID: depression: 20%; anxiety; 36%; PTSS: 23%]; [general BID: depression: 32%; anxiety: 87%; PTSS: 38%]). The mediating effect of BID was less pronounced for the association between scarring/disfigurement of the body and psychological distress for both males and females. Conclusions Body image dissatisfaction mediates the association treatment‐related scarring/disfigurement and psychological distress among adult survivors of childhood cancer, particularly among survivors with scarring/disfigurement of the head and male survivors. Successful treatment of body image dissatisfaction has the potential to eliminate a substantial proportion of psychological distress related to scarring/disfigurement among adult survivors of childhood cancer.
