To simplify the sharing process, we reran the analyses from Karlsson Linnér et al. (2021), removing the 23andMe samples. To obtain the EXT-23andMe summary statistics, we applied the EXT1.0 genomic structural equation model to the summary statistics of GWASs on externalizing behaviors and disorders that exclude 23andMe data. The EXT-23andMe model structure, fit, and parameters were similar to those of the original analysis; and the EXT1.0 and EXT-23andMe factors had similar genetic correlations with external traits. The variance in externalizing behaviors explained by the polygenic score for externalizing decreased from 8.9% to 8.4% for COGA and from 10.5% to 8.6% for Add Health when using the EXT-23andMe summary statistics to calculate polygenic scores.
Those analyses will be reported in Williams et al. (manuscript in preparation). To obtain these summary statistics (EXT–23andMe), please complete this form.
