ABSTRACT
The focus of the present study is on the psychological and social dimensions of collective trauma resulting from the intense impact of strong emotional and stress factors connected with the COVID-19 pandemic and the crisis in Ukraine in parents of children with oncological diseases. The process of overcoming collective trauma in its diversity is a long one and requires specific care. The challenge of recovery is to regain the sense of control over the mental, economic and social parameters of the individuals affected. For the group of parents studied this includes discovery of a way for the caregivers to be calm and focused on the accompanying care for the child with an oncological disease, even in a pandemic situation and war. The effective overcoming collective trauma of the sense of imminent danger in society is based on public support and personal responsibility. Fear, anger, depression, isolation and lack of resources that are a direct psychological and economic result of pandemic and war, aggravates the quality of life of patients. As socially determined parameters, they carry a high risk of the recurrence and mortality of children with malignant diseases.
