Abstract
One hundred nineteen clients diagnosed with borderline personality disorders participated in a correlational study using standard intelligence and achievement measures. We expected to confirm the presence of an organic subtype that might help clinicians who work with this group of clients (average IQ = 79.3). We found gender differences that tended to support previous research on male-female differences. In general, the data supported the presence of an organic subtype. Analyses of arrest history and additional differential diagnoses showed this category of client relatively free of dependency concerns but manifesting signs of an anxiety disorder.
