To assess whether test linking was successful within the seven cohorts that assessed more than one personality inventory, latent scores were computed based on different calibrations. In the majority of cohorts, the correlations among estimated scores were very high for most of the inventories (r > 0.96). Only for TCI Neuroticism in the HBCS cohort, was the correlation lower (r = 0.87). Thus, the latent scores are largely independent of the inventories included. TICs for these cohorts are presented in Supplementary Figs. 4–27. Supplementary Figs. 11, 14, 18, and 20 thru 23 show that combining tests always leads to higher information content, and therefore more measurement precision for those individuals with multiple-inventory data. However, the TICs of the combined tests are not a simple sum of the TICs of the individual tests, showing that the personality inventories largely, but not completely, measure the same phenotypes.
