In Canada, approximately 1450 children are diagnosed with cancer annually. Diagnosis of childhood cancer and its aggressive treatment can have devastating psychosocial effects on the whole family (e.g. unpleasant feelings or emotions that impact your daily activities). It is not known whether health care providers who treat these children use and value psychosocial tools or how beneficial the use of these tools is for these families. This research team will test the benefits of using psychosocial screening on the quality of life of treated children, parents and siblings.
