Risks repeatoffending calculated using fixed- random-effectsmodels calculate pooled odds ratios (ORs). Subgroupand meta-regression analyses examinehow estimates affected by various study charac-teristics including mean sample age,study location, samplesize,studyperiod,outcomemeasure,durationoffollow-up,and diagnostic criteria. Results: Twenty-seven studies,which included 3511 psychosis, iden-tified. Compared without any psychiatricdisorders, there significantly increased (pooled OR 1.6,95% confidence interval [CI] 1.4–1.8), although this wasonly based 4 studies. In contrast, no associ-ation when disorderswere used as comparison group 1.0,95% CI 0.7–1.3), substantial hetero-geneity. Higher found female-onlysamples studies theUnited States. Conclusions: The association between psy-chosis differed depending com-parison group.
