The development of schizophrenia in late adolescence.

Adolescence is an unusual psychologic time. A recent psychodevelopmental approach to psychosis attempted to show how psychotic signs might arise from typical features of adolescence; for example, delusions appear to reflect common adolescent themes of attachment and autonomy. This psychodevelopmental approach emphasizes how normal adolescents grow out of a natural egocentricity and idealism through learning about others; this theory converges with more recent neurologic theories. (Such neurologic theories agree that mentalizing-for others abilities are a crucial mechanism whereby the suspected neurologic problems of psychosis translate into the symptoms.) A psychodevelopmental account implies a therapeutic priority would be reattaching psychosis sufferers with their peer group, perhaps through work placement schemes. It also recommends cognitive work directing self-consciousness into understanding other people. Psychodevelopmental approaches offer a useful theoretic background for psychologic interventions with young "at risk" people.
