Child and adolescent psychiatry or pediatric psychiatry is a branch of psychiatry that focuses on the diagnosis, treatment, and prevention of mental disorders in children, adolescents, and their families. It investigates the biopsychosocial factors that influence the development and course of these psychiatric disorders and treatment responses to various interventions. Child and Adolescent Psychiatry training emphasizes developmental considerations. Biological, sociocultural, psychodynamic, behavioral, and familial aspects of childhood and adolescence and their problems are covered in both clinical and didactic experiences. Consultation with ambulatory and hospital pediatric services is an essential part of child and adolescent training. In addition, residents consult with schools, courts and social welfare agencies.
