We assessed the validity of our subsyndromal categories in two ways.First,we compared all the cross-disorder phenotypic correlations using the original dichotomous full-syndrome variables (tetrachoric correlations) with the three-category variables (polychoric correlations);
95% confidence intervals for these two correlations overlapped for 65 of 66 correlations.Second,using a multiple-threshold model in PRELIS 2.3 (36),we tested whether the three categories represented differing levels of severity on a single continuum of liability.This test failed at the 5% level three of 46 times,consistent with chance expectations (37).
