The “Psychosis Risk” proposal has stimulated widespread opposition (even I am told from within the Workgroup itself). The arguments against it are simply overwhelming. The false positive rate in predicting psychosis would be between 70-90%, meaning that between two and nine youngsters would be misidentified for every one accurately identified. The treatment most likely to be used would be antipsychotic medications. These have no proven efficacy in preventing psychosis, but most definitely have terrible side effects- especially enormous weight gain and its life threatening complications. These medications are overprescribed to those least able to resist- the young and those who are most financially disadvantaged.
