Approximately 1–3% of the general population may be diagnosed with HPD.  Major character traits may be inherited, while other traits may be due to a combination of genetics and environment, including childhood experiences.  This personality is seen more often in women than in men.  It has typically been found that at least two thirds of persons with HPD are female, however there have been a few exceptions.  Whether or not the rate will be significantly higher than the rate of women within a particular clinical setting depends upon many factors that are mostly independent of the differential sex prevalence for HPD.  Those with HPD are more likely to look for multiple people for attention which leads to marital problems due to jealousy and lack of trust from the other party. This makes them more likely to become divorced or separated once married.

A new self-rated scale to measure severity and change in persons with borderline personality disorder (BPD) is described. The Borderline Evaluation of Severity Over Time (BEST) was developed to rate the thoughts, emotions, and behaviors typical of BPD. Data were collected in the course of a randomized controlled trial (RCT) of Systems Training for Emotional Predictability and Problem Solving (STEPPS) for subjects with BPD. The instrument showed moderate test-retest reliability, high internal consistency, and high discriminant validity. Its 15 separate items showed a moderate or better correlation with the total score. The BEST was also sensitive to clinical change as early as week 4 of the RCT and correlated highly with other measures of illness severity. We conclude that the new scale is both reliable and valid in measuring severity and change in persons with BPD.
