Appendix 1—table 2. Group differences in Empathic and personality traits, and in scores of pain sensitivity and coping.

Scores are described in terms of mean and standard deviation. Italicized values on grey background refer to significant group differences, as measured through one-way Analysis of Variance (Exp. 1, SPQ P: F_(3,116) = 5.73, p=0.001; Exp. 2, BF C: F_(1,48) = 8.80, p=0.005; all other variables: Exp. 1, F_(3,116) ≤ 2.35, p≥0.076, Exp. 2, F_(1,48) ≤ 2.96, p≥0.092). IRI: Interpersonal Reactivity Index; PT: Perspective Taking; EC: Empathic Concern; PD: Personal Distress; FS: Fantasy; SPQ: Situational Pain Questionnaire; P: Receiver operating characteristic curve probability; PCS: Pain Catastrophizing Scale; BF: Big Five Inventory; E: extroversion; A: agreeableness; C: conscientiousness; N: neuroticism; O: openness.
