Two studies examined the general factor of personality (GFP) in relationship to performance on video-based situational tests measuring social knowledge and skills. Study 1 (N = 180 candidates of an assessment center) showed that high-GFP individuals were better able to indicate the appropriate social behavior in a situational judgment test. Moreover, in that study, high-GFP participants were also rated higher by others on leadership skills. Study 2 (N = 153 psychology students) showed that the GFP was related to actual display of social behavior in a situational webcam test. In both studies, high-GFP individuals reported more leadership experience in organizations. These findings support the idea of the GFP as a substantive personality factor that may also be relevant for personnel selection. © 2014 Hogrefe Publishing.
