To describe 1-year outcome in a large clinical epidemiologic sample of first-episode psychosis and its predictors.
A total of 301 patients with first-episode psychosis from four healthcare sectors in Norway and Denmark receiving common assessments and standardized treatment were evaluated at baseline, at 3 months, and at 1 year.
Substantial clinical and social improvements occurred within the first 3 months. At 1-year 66% were in remission, 11% in relapse, and 23% continuously psychotic. Female gender and better premorbid functioning were predictive of less severe negative symptoms. Shorter DUP was predictive for shorter time to remission, stable remission, less severe positive symptoms, and better social functioning. Female gender, better premorbid social functioning and more education also contributed to a better social functioning.
This first-episode sample, being well treated, may be typical of the early course of schizophrenia in contemporary centers.
To identify predictors of non-remission in first-episode, non-affective psychosis.
During 4 years, we recruited 301 patients consecutively. Information about first remission at 3 months was available for 299 and at 2 years for 293 cases. Symptomatic and social outcomes were assessed at 3 months, 1 and 2 years.
One hundred and twenty-nine patients (43%) remained psychotic at 3 months and 48 patients (16.4%) remained psychotic over 2 years. When we compared premorbid and baseline data for the three groups, the non-remitted (n = 48), remitted for
