INTREPID II: International Research Programme on Psychoses In Diverse Settings

INTREPID II is a research programme to study the epidemiology, phenomenology, aetiology and outcome of psychotic disorders in diverse settings. It builds on previously-developed methods for the study of schizophrenia and other psychoses from the INTREPID I pilot study. 

The overall aim of the five-year research programme is to investigate the variability - in incidence, presentation, outcome, and impact - of psychotic disorders in diverse developing countries. The programme takes place in sites in three countries (India, Nigeria, Trinidad) and consists of four inter-connected studies, aiming to:

(1) investigate the incidence and presentation of untreated psychotic disorders in each site and associated risk factors;

(2) investigate the 2-year course and outcome of psychotic disorders and associated factors;

(3) investigate (a) help-seeking and (b) the impact of psychotic disorders on individuals and families, using a combination of quantitative and qualitative approaches;

(4) investigate the types and prevalence of physical health problems and related risk markers.
