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 psychiatric disorders and treatment responses to various interventions. Child and adolescent psychiatrists primarily use psychotherapy and/or medication to treat mental disorders in the pediatric population.
When psychiatrists and pediatricians first began to recognize and discuss childhood psychiatric disorders in the 19th century, they were largely influenced by literary works of the Victorian era. Authors like the Brontë sisters, George Eliot, and Charles Dickens, introduced new ways of thinking about the child mind and the potential influence early childhood experiences could have on child development and the subsequent adult mind. When the Journal of Psychological Medicine and Mental Pathology, the first psychiatric journal in English, was published in 1848, child psychiatry didn't exist as its own field yet. However, some of the earliest works on the possibility of nervous disorders and "insanity" in children were published in the Journal and several medical writers directly referenced works such as Jane Eyre (1847), Wuthering Heights (1847), Dombey and Son (1848), and David Copperfield (1850), to illustrate this new conceptualization of the child mind. Until that time, it was generally accepted that children were free from nervous disorders and the "passions" that affected the adult mind.
As early as 1899, the term "child psychiatry" (in French) was used as a subtitle in Manheimer's monograph Les Troubles Mentaux de l'Enfance. However, the Swiss psychiatrist Moritz Tramer (1882–1963) was probably the first to define the parameters of child psychiatry in terms of diagnosis, treatment, and prognosis within the discipline of medicine, in 1933. In 1934, Tramer founded the Zeitschrift für Kinderpsychiatrie (Journal of Child Psychiatry), which later became Acta Paedopsychiatria.
