Abstract
81 men and 82 women were administered Schill's (1990) Self-defeating Personality Scale and Coolidge's (1992) Axis Two Inventory. As expected, Schill's and Coolidge's measures of self-defeating personality disorder were highly correlated (.70 for men and .74 for women). Scores on Schill's scale also had correlations > .50 with scores on six of the other personality disorder scales for men and five for women. This argues against self-defeating personality disorder as measured by Schill's scale being a distinct construct. The pattern of the correlations suggests that besides assessing a person's maladaptive self-defeating traits, Schill's measure also may assess the person's anxiety and concerns about interpersonal relationships.
