More than ever, young people are exposed to a variety of influences at an early age; social and academic demands are increasing, and close family networks are often no longer present. Self-confidence, social skills, and strategies for stress management and conflict resolution still need to be developed. Often, there is a discrepancy between one's own protective resources and the demands of everyday life. This book addresses the complex variety of symptoms, which can vary greatly depending on age and development, the associated occurrence of depression with other psychiatric or chronic somatic disorders, potential psychosocial stress and risk factors, all diagnostic methods, as well as psychotherapeutic, pharmacological, and adjunctive treatment strategies.
