Depression is frequently associated with other psychiatric disorders and is often related to chronic health problems. Depressive symptoms are also common in chronically distressed close relationships and severe interpersonal difficulties in families and at work. The topic of depressive comorbidity is clearly very important, and while recent research in this area has been methodologically sophisticated, well presented, and inherently interesting, there has not been a comprehensive, academic resource that covers recent developments in this area.The Oxford Handbook of Depression and Comorbidity brings together scholarly contributions from world-class researchers to present a careful and empirically based review of depressive comorbidity. Cutting-edge chapters address theory, research, and practice, while capturing the diversity, evidence-base, and importance of depressive comorbidity. Specific topics include the comorbidity between depression and PTSD, alcohol use, and eating, anxiety, panic, bipolar, personality, and sleep disorders, as well as schizophrenia, suicide, cardiovascular disease, cancer, pain, obesity, intimate relationships, and many more. The Oxford Handbook of Depression and Comorbidity is a unique and much-needed resource that will be helpful to a broad range of researchers and practitioners including clinical and counseling psychologists, psychiatrists, marital and family therapists, social workers, and counselors working in mental-health and general health-care settings, as well as students in these areas.
