The Subjective Overachievement Scale (SOS): Self-Doubt subscale is an 8-item measure designed to identify subjective overachievers, or individuals who are concerned about having successful performances yet are doubtful about possessing the underlying talent or ability to achieve success. This measure was developed along with the Subjective Overachievement Scale (SOS): Concern with Performance, found here.
