Marsha Linehan Obituary, Death – DBT Pioneer Reportedly Dies at 83

The psychology and mental-health communities are mourning the reported death of Dr. Marsha M. Linehan, the American psychologist widely recognised for developing Dialectical Behavior Therapy (DBT). Reports published on November 11, 2026, state that she died on November 10 at the age of 83.

Linehan’s reported passing has drawn attention to a career that significantly influenced the treatment of borderline personality disorder, suicidal behaviours and severe emotional dysregulation. Her work helped establish DBT as an important evidence-based approach in clinical psychology.

Born on May 5, 1943, in Tulsa, Oklahoma, Linehan became a professor of psychology at the University of Washington. She also led the university’s Behavioral Research and Therapy Clinics before retiring in 2019.

Her most influential contribution was the development of Dialectical Behavior Therapy. Initially designed to help people experiencing suicidal behaviours, the treatment was subsequently adapted for borderline personality disorder and other complex mental-health conditions.

Through her research, clinical work, publications and professional training programmes, Linehan influenced generations of therapists and researchers. Her memoir, Building a Life Worth Living, also offered readers a personal account of her experiences and the development of her therapeutic approach.

Reports of her death have circulated within the DBT professional community, and a university tribute published in Italy has also reported her passing. However, a direct public announcement from the University of Washington or the Linehan Institute was not located in the sources reviewed. Further details concerning memorial arrangements have not been independently established.

Marsha Linehan’s professional legacy is reflected in the continued use and study of DBT and in the clinicians, researchers and individuals whose lives have been influenced by her work.
