Note. Years of measurement: T1 = 1984; T2 = 1987; T3 = 1990; T4 = 1993; T5 = 2004; T6 = 2007; and T7 = 2010. Of the total analytic samples, 60.75% (n = 1,187) were deceased for openness (97 more died after T7); 63.05% (n = 1,355) were deceased for neuroticism (106 more died after T7); and 63.15% (n = 1,357) were deceased for extraversion (105 more died after T7). We also note that there is an increase in participants who provided openness scores from T1 to T2 because the T1 openness measure was included in a second booklet that was sent to participants after they had returned their first booklet. The first booklet contained the Eysenck Personality Inventory.
