Supplementary Table 1 and Supplementary Fig. 3 give an overview of the personality inventories administered in each cohort. The Supplementary Materials Online describes these inventories in detail. For the Neuroticism analysis, we included all Neuroticism items from the NEO, the International Personality Item Pool (IPIP) and Eysenck (EPQ, EPI, ABV) inventories, the Harm Avoidance (HA) items from the Temperament and Character Inventory (TCI), and the Negative Emotionality (NEM) items (excluding the aggression items) from the Multidimensional Personality Questionnaire (MPQ). The Neuroticism scales of the NEO, IPIP and Eysenck inventories consist of different items, but there is strong overlap in item content and the sum scores correlate highly across inventories (Aluja et al. 2004; Draycott and Kline 1995; Larstone et al. 2002). HA correlates most strongly with Neuroticism (as assessed with the NEO-PI-R or EPQ-R) (De Fruyt et al. 2000; Gillespie et al. 2001). NEM corresponds most closely to Neuroticism, although NEM is a broader concept because it also includes items about aggressive behavior.
