Аннотация:Cancer and its treatment are negative experiences that can lead to depressive experiences, especially in older adolescents who have survived cancer. For rehabilitation and subsequent integration into society, it is important to understand the psychological status of adolescents who have survived cancer. Some of the most common cancers among children are posterior fossa tumors and acute lymphoblastic leukemia. The aim of our study was to compare the depressive mood background among older adolescents who survived acute lymphoblastic leukemia and posterior fossa tumors. The study involved older adolescents (N = 138) aged 14-18 (M = 15.5, SD = 1.1). Of these, 83 (41 boys) survived acute lymphoblastic leukemia and 59 (30 boys) survived posterior fossa tumors. The CDI Children‘s Depression Inventory questionnaire was used to assess the depressive mood background. Children who survived acute lymphoblastic leukemia have higher rates of depression than children who survived medulloblastoma; the significance level of differences according to the Mann- Whitney test was p = 0.05. Among children with acute lymphoblastic leukemia survivors, 57% of children have increased depression scores. At the same time, in the group of children who survived medulloblastoma, the number of children who have an increased score on the depression scale is 52%. Children who survived acute lymphoblastic leukemia have higher rates of depression than their counterparts who survived medulloblastoma. Thus, among children with cancer survivors, acute lymphoblastic leukemia has an increased risk of a depressive mood background
