Early detection and intervention evaluation for people at high‐risk of psychosis‐2 (EDIE‐2): trial rationale, design and baseline characteristics

Aims: Much research has begun to focus on the identification of people who are at high risk of developing psychosis, and clinical services have been initiated for this population. However, only a small number of studies have reported on the efficacy of interventions for preventing or delaying the onset of psychosis. The results of prior work suggest that cognitive therapy (CT) may be an effective, well‐tolerated treatment. We report on the rationale and design for a large‐scale, multi‐site randomized, controlled trial of CT for people who are assessed to be at high risk of psychosis because of either state or state‐plus‐trait risk factors.
