Gunderson's early interest was in the area of
schizophrenia, and he published with
Loren Mosher an edited book on its psychotherapy in 1975. That same year, he published a seminal paper with
Margaret Singer identifying borderline personality disorder (BPD) as a distinct form of psychopathology. His career thereafter shifted towards focus on the treatment of borderline patients. Gunderson published nearly 250 papers, 100 reviews, and 12 books regarding borderline and other personality disorders. In 1984, he published his major textbook on BPD, simply titled
Borderline Personality Disorder. According to Massachusetts General Hospital, his success led to him being called the "father" of BPD. He led the academic group that described personality disorders in the fourth edition of the
Diagnostic and Statistical Manual of Mental Disorders (DSM). In 2009, McLean Hospital named a treatment center in
Cambridge, Massachusetts, after him, called the "Gunderson Residence." In the latter part of his career, Gunderson developed a treatment model called "
Good Psychiatric Management" (or "General Psychiatric Management"), a psychodynamically-informed psychotherapy for BPD. The development of GPM was based, in part, on research that shows that less intensive, easier-to-learn therapies could be nearly as effective as more developed approaches (
DBT,
TFP,
MBT), and would cater to unmet needs often seen in the clinical setting. Gunderson theorized that the patient with borderline personality disorder suffers from a fundamental interpersonal hypersensitivity and that this problem is at the core of the various symptoms associated with the disorder. Gunderson is remembered as a theoretical pluralist who attempted to bridge gaps between sometimes-competing approaches to BPD. His work helped open the door to the effective management of a group of patients historically deemed untreatable by traditional psychoanalysis. ==Honors and awards==
