All participants were administered the 140-item version of the Temperament and Character Inventory-Revised (TCI-R), a Likert-scale self-report questionnaire (Cloninger 1999; Hebrew: Zohar and Cloninger 2011), measuring four temperament dimensions (Novelty Seeking, Harm Avoidance, Reward Dependence, and Persistence) and three character dimensions (Self-directedness, Cooperativeness, and Self-transcendence).
