Dr. Marsha M. Linehan, the psychologist who created Dialectical Behavior Therapy and helped change what was thought possible for people at high risk of suicide, died in Seattle on November 10, 2026. She was 83. She had been hospitalized for pneumonia. Today we honour her life, her courage, and the hope her work made possible.
Linehan was professor emerita of psychology at the University of Washington, where she served from 1977 until her retirement in 2019. Over those decades she developed Dialectical Behavior Therapy, or DBT, a treatment that brought together change-oriented behavioural methods with skills of acceptance and mindfulness. It was the first psychotherapy for borderline personality disorder to be supported by a controlled trial, and it was built for people many clinicians had considered untreatable.
That starting point mattered. DBT did not begin as a theory in search of a problem. It began with people who were in profound pain, often living with chronic suicidal behaviour, and with a determination to find a treatment that could actually help. A controlled study published in 1991 reported that people who received DBT were less likely to harm themselves and less likely to leave treatment than people who received usual care. Manuals followed in 1993, and the approach was later studied and adapted more widely. What did not change was the conviction at its centre: that people in extreme distress deserve a therapy rigorous enough, and compassionate enough, to help them stay alive and build a life they want to live.
Linehan later made public a part of her own story that had long been private. At 17 she was hospitalized at the Institute of Living in Hartford. In 2011, she spoke about that experience, including in a New York Times profile, and she explained her decision in a sentence that has been widely remembered: "I cannot die a coward." She had come to believe that people who were struggling needed to know that recovery could be real, because she had lived the cost of being told it might not be.
The phrase most closely associated with her work is "a life worth living." It was not a slogan. It was the goal she set for treatment, and the title she later gave her memoir, Building a Life Worth Living. It named something both modest and radical: that the point of care is not merely the absence of crisis, but a life a person can recognize as their own, with meaning, connection and reasons to stay.
Her death will be felt by clinicians, researchers, and by many people who learned DBT skills in the hardest seasons of their lives. The most faithful tribute is not to polish the story, but to remember what she insisted on: that people who suffer deserve to be taken seriously, and that a life worth living is a goal worth building, skill by skill.
