Social and symptomatic outcomes of first-episode bipolar psychoses in an early intervention service.

Aim: We aimed to establish the relative proportions of all diagnoses in people aged 14-35 years presenting to an early intervention in psychosis service, and to compare demographic variables, symptoms and outcomes between the bipolar psychoses and other psychoses at 3-6 months and 1 year post referral.

Methods: Prospective 3- to 6-month diagnostic and symptomatic assessments were carried out. Diagnoses were established using the Diagnostic Interview for Psychoses - Diagnostic Module.
