Chronic sample patient and controls differed on gender, X 2(1) = 5.965, p = .018, years of education, t(694.01) = 6.418, p < .001, d = 0.472, and WRAT‐3, t(689.50) = 4.093, p < .001, d = 0.305. Early psychosis sample patient and controls differed on years of education only, t(75) = 3.717, p < .001, d = 0.845.
