This document discusses a proposed study on the effects of internet peer-support groups on individuals with borderline personality disorder (BPD). BPD is characterized by unstable emotions and impulsivity, and has a high risk of self-harm and suicide. While only 39% of Americans with personality disorders receive treatment, many turn to online peer-support groups, which offer 24/7 support and accessibility. The study hypothesizes that usage of online peer-support groups will positively correlate with coping ability, while social media usage alone may negatively correlate. It plans to survey a random sample of members from several peer-support groups using established questionnaires measuring self-harm, social media use, and BPD emotions to test these hypotheses.
