【 摘 要 】

Background: Best practice guidelines recommend traumatic events should be assessed in psychosis to support the identification and, when indicated, treatment of post-traumatic stress reactions. However, routine assessment in frontline services is rare, and available tools are not tailored to psychosis. Assessment obstacles include lengthy measures, a focus on single, physically threatening events, and the exclusion of psychosis-related traumas. Objective: To develop and validate a brief trauma screening tool for the identification of clinically significant traumas in people with psychosis. Method: The Trauma and Life Events (TALE) checklist was developed in conjunction with people with lived experience of trauma and psychosis, and specialist clinicians and researchers. The psychometric properties (i.e. test-retest reliability, content validity, construct validity) of the TALE were evaluated in a sample of 39 people with psychosis diagnoses. Results: The TALE displayed moderate psychometric acceptability overall, with excellent reliability and convergent validity for sexual abuse. High rates of psychosis-related trauma and childhood adversity were reported, in particular bullying and emotional neglect. A dose–response relationship between cumulative trauma, post-traumatic stress and psychosis was found. Conclusions: The TALE is the first screening tool specifically designed to meet the needs of routine trauma screening in psychosis services. The psychometric limitations highlight the challenge of developing a measure that is both sufficiently brief to be useful in clinical settings and comprehensive enough to identify all relevant adverse events. Validation of the TALE is now required across the spectrum of psychosis.
