The investigators second aim is to develop a website for teaching the most up-to-date information about BPD and assessing three key outcomes: the severity of borderline psychopathology, psychosocial impairment, and treatment utilization over time. These outcomes will be assessed using self-report measures with proven psychometric properties. Symptom severity will be accomplished through the internet-based administration of the self-report version of the already widely used Zanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD)—a dimensional measure of the nine Diagnostic and Statistical Manual of Mental Disorders, fourth edition(DSM-IV) symptoms of BPD. The investigators will also use the Borderline Evaluation of Severity over Time (BEST) developed by Pfohl and Blum as a secondary measure of change in severity of borderline psychopathology. Two other self-report measures will be used to assess psychosocial impairment (Sheehan Disability Scale and Weissman's Social Adjustment Scale). The use of nine forms of psychiatric treatment will be assessed using a self-report version of the treatment section of the Background Information Schedule and its follow-up analog.
