Psychosocial oncology is a health psychology specialty that focuses on the psychological, behavioral, emotional, and social challenges faced by patients with cancer and their loved ones. Cancer can cause significant distress, and psychosocial interventions are known to be effective for helping patients and families navigate the many issues that can arise at any stage of the cancer continuum. This volume provides psychologists, physicians, social workers, and other health care providers with practical and evidence-based guidance on the delivery of psychological interventions to patients with cancer. The multidisciplinary team of authors succinctly present the key principles, history, and theoretical models of cancer-related distress and explore clinical assessment and interventions in cancer care, in particular psychological and psychiatric treatments, multidisciplinary care management, and supportive interventions. Case vignettes provide clear insights into diagnostic processes and treatment planning, and printable handouts and screening tools are invaluable for practitioners.
