Good Psychiatric Management or General Psychiatric Management (GPM) is a psychodynamically informed treatment for borderline personality disorder (BPD) developed by John G. Gunderson. Initially created as a control group for BPD randomized controlled trials (RCTs), this treatment proved so effective that it was implemented and is still used today. Gunderson sought to create a treatment that could be easily used in mental health services and that integrated what he believed to be the most effective components of existing treatments. Central to the case formulation model is the interpersonal hypersensitivity of the patient diagnosed with BPD, which is believed to underlie the symptoms of this disorder and should be a primary focus of intervention.
