BACKGROUND: Baseline functioning has been found to be a strong predictor of transition to psychosis in ultra high risk populations. However, the time course of functioning may enhance prediction. We investigated whether there were different patterns of functioning over time and whether particular temporal patterns were related to baseline characteristics and psychosis outcome. METHOD: Functional data was assessed at baseline and after 3 to 6year follow-up in an ultra high risk sample (n=158; 92 female, mean age=19.28 (SD=3.33), range=14-29). Using the median score of the GAF and the QLS scale, a 'High' and 'Low' group (comprising of subjects functioning above or below median at both baseline..View full abstract
