Factor analysis of scores from specifically selected tasks (emotion recognition (BLERT), ToM (Hinting Task), Social Attribution (SAT-MC), four empathy subscales (IRI), and two subscales of Self-Experience of Relatedness (BORRTI)), yielded three factors that explained more than 62% of the variance and which we named Interpersonal Discomfort, Basic Social Cognition, and Empathy.
The Interpersonal Discomfort factor was comprised of the Personal Distress subscale of the IRI and the Alienation and Egocentricity scores from the BORRTI. We chose the descriptive term "Interpersonal Discomfort" because it is a bridging construct between the Personal Distress captured by the IRI and the alienation and withdrawal into an egocentric self-protective view of relatedness that is measured by Alienation and Egocentricity on the BORRTI.
