Personality Change Study for Borderline Personality Disorder

Participants will be randomized to a 2- or 4-week assessment-only baseline period. After the baseline period, participants will receive the personality-based treatment module corresponding to their highest clinical elevation (i.e., neuroticism, \[low\] conscientiousness, \[low\] agreeableness). Treatment will consist of six weekly 50-60-minute sessions. After the 6-week intervention period, participants will complete a 4-week follow-up period to determine the sustainability of effects observed
