Psychological interventions for trauma in individuals who have psychosis: A systematic review and meta-analysis
Bibliographic record
Abstract
Background: Psychological interventions, in particular those derived from cognitive-behavioural therapy frameworks, and eye movement desensitisation and reprocessing, are effective for reducing post-traumatic stress disorder and associated distress. To date, studies have tended to exclude individuals who have psychosis; a clinical population who are known to be at risk of experiencing trauma. Whether people with psychosis also benefit from trauma-focussed psychological therapies (TFPT) warrants further investigation.Method: A systematic search for randomised controlled trials was undertaken. Data were synthesised using narrative and meta-analytic approaches.Results: Five studies met the review inclusion criteria. Study findings overall indicate that TFPT are effective for reducing intrusive thoughts and images, negative beliefs associated with traumatic memories, hypervigilance, and avoidance. Limited data were available about the utility of interventions for improving mood, anxiety and quality of life. Attrition rates were comparable for participants offered active and control conditions.Conclusion: Findings are consistent with those reported for the non-psychosis population. Future studies should establish which interventions are more acceptable and glean more favourable outcomes for this clinical population.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
