The magnitude of the correlations of the EXT and ARF factors with external criteria were generally similar and their confidence intervals were often overlapping (Figure 4A). Further, the correlation between the effect sizes for the two factors was 0.96 and the median absolute difference in correlations was 0.06 (Figure 4B). The χ2 difference tests indicated that externalizing and the addiction risk factor were statistically significantly differentially correlated with 21 of 84 external criteria (see Figure 4A and Table S6). However, many of these differences were small in magnitude, reflecting the sensitivity of the test to large sample size. The greatest differences EXT and ARF were observed for tobacco-related phenotypes (age of initiation [rgARF = −0.57, rgEXT = −0.69, |Δrg| = 0.12] and cigarettes per day [rgARF = 0.49, rgEXT = 0.34, |Δrg| = 0.15]); and certain personality traits (neuroticism [rgARF = 0.37, rgEXT = 0.12, |Δrg| = 0.25] and extraversion [rgARF = 0.11, rgEXT = 0.34, |Δrg| = 0.23]); and other forms of psychopathology (major depressive disorder [rgARF = 0.56, rgEXT = 0.45, |Δrg| = 0.12 and schizophrenia [rgARF = 0.43, rgEXT = 0.27, |Δrg| = 0.16).
