The investigators third aim is to conduct a small-scale randomized controlled trial of psychoeducation for BPD using this set of web-based instructional and assessment tools. Half of the 80 subjects will be randomized to the investigators web-based intervention, which will occur a week after diagnostic disclosure, and half will not. The investigators plan to assess symptom severity, psychosocial impairment, and treatment utilization each week for 12 weeks (as the investigators did in our prior study) using the web-based self-report measures described above to determine its immediate effects. The investigators also plan to assess these outcomes using these measures at six months, nine months, and 12 months after randomization to determine if these effects are long lasting. The investigators hypothesize that two of the nine symptoms of DSM-IV BPD will decline significantly more in the subjects who receive psychoeducation than those who do not-general impulsivity and unstable relationships. The investigators further hypothesize that those in the treatment group will have more improved functioning in the social and vocational (but not family realm) than those in the non-treatment group. Finally, the investigators hypothesize that those receiving psychoeducation will be more likely to seek out ongoing psychiatric treatment and less likely to use emergency psychiatric services, such as hospitalizations, than those who do not receive psychoeducation concerning BPD.
