Note: All correlations are polychoric correlations. CO = Cooperativeness; ICC_DE = intraclass correlation–double entry (for ICC_DE statistics, corresponding p values provided below as * and **); HA = Harm Avoidance; NS = Novelty Seeking; PERS = Persistence; RD = Reward Dependence; SD = Self-directedness; ST = Self-transcendence; and LEAD = longitudinal, expert, all data; NPD = narcissistic personality disorder; PDQ-4 = Personality Diagnostic Questionnaire-4; Cloninger's TCI = Temperament and Character Inventory.

Indicate that the 95% confidence intervals do not include zero.

Correlations that are significantly different.
