Psychosis in the British Army: a 2-year follow-up study.

Background: Recent research into mental illness in military populations has tended to focus on minor mental illness and the consequences of trauma. The literature contains very little on serious mental illness, including its occupational implications.

Aims: To identify the incidence and factors associated with nonaffective psychosis in British Army personnel, to evaluate service quality in terms of duration of untreated psychosis, and to identify predictors of occupational outcome after 2 years, to inform future management of similar cases.
