iTEST: Introspective Accuracy as a Novel Target for Functioning in Psychotic Disorders
Source: ClinicalTrials.gov · Last updated 18 Mar 2026
Brief summary (registry, in English)
People with psychotic disorders experience a high level of functional disability, and a major contributor to this disability is introspective accuracy, which is defined as inaccurate judgements of one's abilities and performance on tasks. Yet, no intervention has directly targeted introspective accuracy for psychotic illnesses. This trial will evaluate a new intervention, called iTEST, that uses mobile devices to train people with psychotic disorders to improve introspective accuracy and, ultimately, functional outcomes
