Text

Personality scores were estimated for 160,671 (Neuroticism) and 160,713 individuals (Extraversion). Correlations between estimated latent scores and sum scores were high for Neuroticism (79 % of the correlations >0.90, and 50 % >0.95; lowest correlation 0.73) and moderately high for Extraversion (82 % of the correlations >0.80, and 48 % >0.90; lowest correlation 0.60) (Table 2). Correlations were highest with NEO, EPQ and IPIP-based sum scores, and lowest with TCI-based sum scores.Table 2Correlations between the IRT-based Neuroticism and Extraversion scores and the personality inventory-based sum scoresNeuroticismExtraversionCohort N r N r 1.
