Marsha Linehan Obituary, Death – Remembering the Psychologist Behind Dialectical Behavior Therapy

As Professor Emeritus at the University of Washington, Linehan built a career focused on suicidal behaviour, borderline personality disorder and the development of effective psychological treatments.

DBT combines behavioural techniques, mindfulness and practical coping strategies to help individuals manage intense emotions, tolerate distress and improve relationships. Originally developed to address suicidal behaviour, the treatment has since been applied to other complex mental health conditions.

Linehan has also contributed to professional education through research, clinical training and publications, including her memoir, Building a Life Worth Living.

Her influence extends beyond academic research, with DBT now used by clinicians and treatment programmes internationally.

Although an online article has claimed that Linehan died in November 2026, no reliable confirmation of her death was identified in the official sources reviewed. The University of Washington and organisations associated with her work continue to provide professional information about her career and contributions.

Until an authoritative announcement becomes available, claims of her death should not be presented as established fact.
