An error in statistical syntax defining baseline disorder led to misidentification of baseline anxiety disorder in five cases in one of the two reported samples (PREDICT). NAPLS-1 data and previous publications of PREDICT data were not affected. The error affected rows in Table 1 labeled 'DSM-IV anxiety' and 'Any mood/anx disorder' and rows in Table 3 labeled 'Baseline Anxiety Excluded' and 'Any Baseline Mood/ Anxiety Excluded.' Corrected Tables are shown below with corrected numbers in bold. Tables S1-S5 in the data supplement were also affected. Note that the online paper has also been replaced. The abstract is unchanged, and overall findings and conclusions are not affected. One paragraph in the Results describing supplementary tables 1 and 2 is slightly changed (changes in bold): "Sensitivity analyses showed that the CHR vs HSC difference for incident psychosis continued to hold whether analyses included or excluded subjects with each or any baseline disorder from the model (all p's = 0.001, Table S1). Similarly, the lack of CHR vs HSC differences for incident nonpsychotic disorders also continued to hold whether models included subjects with baseline disorder (as non-cases of emergent disorder) or excluded them (all p's = 0.390, Table S2)." We regret the error.
