Abstract

Background: Advances in the ability to identify people at high risk of developing psychosis have generated interest in the possibility of preventing psychosis. Aims: To evaluate the efficacy of cognitive therapy for the prevention of transition to psychosis. Method: A randomised controlled trial compared cognitive therapy with treatment as usual in 58 patients at ultra-high risk of developing a first episode of psychosis. Therapy was provided over 6 months, and all patients were monitored on a monthly basis for 12 months. Results: Logistic regression demonstrated that cognitive therapy significantly reduced the likelihood of making progression to psychosis as defined on the Positive and Negative Syndrome Scale over 12 months. In addition, it significantly reduced the likelihood of being prescribed antipsychotic medication and of meeting criteria for a DSM – IV diagnosis of a psychotic disorder. Analysis of covariance showed that the intervention also significantly improved positive symptoms of psychosis in this population over the 12-month period. Conclusions: Cognitive therapy appears to be an acceptable and efficacious intervention for people at high risk of developing psychosis.

  • Use of good emotion regulation strategies leads to a decrease in the likelihood of developing psychotic symptoms and prescribing medication in high-risk individuals.

    “It would also lead to a decrease in the likelihood of developing psychotic symptoms and prescribing medication in “high-risk” individuals (34)”

    From Mobile intervention for individuals with psychosis, dual disorders, and their common comorbidities: A literature review (2019) · cites this paper as [34]

    The Logistic regression section (page unavailable) reports that cognitive therapy significantly reduced progression to psychosis and the likelihood of being prescribed antipsychotic medication in high-risk individuals. The Study design and intervention section describes cognitive therapy, not a test of “good emotion regulation strategies”; attributing those outcomes specifically to such strategies goes beyond the paper.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
