The Danish National Schizophrenia Project: prospective, comparative longitudinal treatment study of first-episode psychosis.

BACKGROUND First-episode psychosis intervention may improve the course and outcome of schizophrenic disorders. AIMS To describe the Danish National Schizophrenia Project and to measure the outcome of two different forms of intervention after 1 year, compared with standard treatment. METHOD A prospective, prospective, longitudinal, multicentre investigation included 562 patients, consecutively referred over a 2-year period, with a first episode of psychosis. Patients were allocated to supportive psychodynamic psychotherapy as a supplement to treatment as usual, an integrated, assertive, psychosocial and educational treatment programme or treatment as usual. RESULTS There was a non-significant tendency towards greater improvement in social functioning in the integrated treatment group and the supportive psychodynamic psychotherapy group compared with the treatment as usual group. Significance was reached for some measures when the confounding effect of drug and alcohol misuse was included. CONCLUSIONS Integrated treatment and supportive psychodynamic psychotherapy in addition to treatment as usual may improve outcome after 1 year of treatment for people with first-episode psychosis, compared with treatment as usual alone.
