OBJECTIVES: Dignity Therapy (DT) is a brief psychotherapeutic intervention designed to address the psychosocial and spiritual needs of terminally ill patients. Research demonstrates DT's efficacy in reducing dignity-related distress and alleviating psychosocial symptoms like depression and anxiety in terminally ill patients. Its application has been extended to non-terminal patients with chronic conditions, mental health challenges, and children nearing the end of life, with promising results. However, the potential for proxy applications, such as posthumous p-DT (p-DT) - conducted by relatives after a patient's death or on behalf of individuals unable to participate - remains underexplored. METHODS: A case series report that examines three relatives who engaged in posthumous p-DT, highlighting its feasibility and potential benefits. RESULTS: p-DT seems to benefit families and caregivers, promoting emotional resilience and facilitating grieving. SIGNIFICANCE OF RESULTS: Findings suggest p-DT may serve as a valuable tool for bereavement support, warranting further research to expand its scope and accessibility.
