PGDT is a brief, structured evidence-based treatment that combines Prolonged Exposure (PE), Interpersonal Psychotherapy (IPT), and Motivational Interviewing (MI), typically delivered over approximately 16 sessions of 60–90 minutes. It is designed for individuals with Prolonged Grief Disorder (PGD) and focuses on reducing persistent grief-related distress through exposure, emotional processing, and behavioral strategies that support re-engagement with life.
