Ostracism is defined as being ignored or excluded by others. Being excluded during adolescence can result in various problem behaviors and emotional disturbances. The purpose of the study is to evaluate ostracism in adolescent cancer patients and define the predictors of it.


The study was conducted as a multicenter survey study. Adolescent cancer patients, who were under remission, were evaluated with structured questionnaires to assess the Ostracism and clinical parameters associated with it. Turkish version of Ostracism Experience Scale for Adolescents (OES-A) and Kutcher adolescent depression scale (KADS) were used.


Between December 2017 and April 2018, 52 patients were evaluated in 4 different cancer centers. Median age was 21 (14-24), 40.4% of them were female and most of them were university student (23, 44.2%). Median OES-A score was 23.5(11.0-41.0). While female sex (28.0 vs 19.0, p = 0.008) and low family income (28.0 vs 21.0, p = 0.02) were associated with more ostracization; patients working full/part time (19.0 vs 25.0, p = 0.01) and university students (19.0 vs 27.0, p = 0.01) were less ostracized. In multivariate analysis, being female was associated with high OES-A scores (OR: 7.8, CI(95%) 1.4-42.9, p = 0.018). Being university student (OR: 0.14, , CI(95%) 0.02- 0.71, p = 0.018) and working (OR: 0.07 , CI(95%) 0.007- 0.7, p = 0.02) were associated with low OES-A scores(Table). Higher OES-A scores were associated with high KADS scores (9.0 vs 7.5, p = 0.16).Table: 1543P

It is the first data about ostracism in adolescent cancer patients. OES-A score was higher than the scores of adolescents without cancer. While female adolescent patients were found to be under risk of ostracism, working and being university student were protective against ostracism. Ostracism in adolescent cancer patients should be studied in larger series.
