Prolonged Grief Treatment

What is PGT?

Prolonged Grief Treatment (PGT) is a treatment specifically designed to help people who feel stuck in their grief. The treatment has a specified time frame and targets 6 Healing Milestones. Therapists trained to do this treatment are skilled in meeting grievers where they are and helping them learn ways to accept their new reality and restore their wellbeing through gentle guidance. The therapy includes sharing and discussing information about grief and adapting to loss and the use of a series of activities that promote experiential learning along as well. 

The Evidence-Base for PGT

The efficacy of PGT was tested in 3 carefully conducted research studies funded by the National Institute of Mental Health. One was focused on older adults and the other two on adults of any age. Since Prolonged Grief is most often confused with depression, we compared PGT to well established efficacious treatment for depression. More specifically, two of the studies compared PGT to Interpersonal Psychotherapy (IPT) for Depression, and one evaluated whether antidepressant medication was effective for grief when administered by a grief-informed physician and also whether it improved the outcome of PGT. Here’s what we found: 

  • PGT was twice as effective as IPT in reducing grief intensity and the degree to which the loss disrupts a person’s life
  • Antidepressant medication had no effect on grief symptoms; however, the addition of medication did help reduce co-occurring depressive symptoms when present
  • Rates of suicidal ideation diminished to a substantially greater extent among participants receiving PGT than among those who did not

How it's different from other therapy

People with PG often know they are stuck in their grief and seek help from a therapist. Grief therapy is often helpful but usually insufficient to get their lives back on track.  Good supportive therapy with an empathic mental health therapist is similarly helpful but insufficient. Efficacious treatments for depression or PTSD can be helpful if these conditions are present with Prolonged Grief,  but again, are not very effective in addressing grief.  

What this means is that when a person with PG reaches out to a trained professional, they are often disappointed with the results.  Over time, they begin to feel discouraged, helpless, and confused. Their experience reinforces the idea that the only thing that can help is for their loved one to be alive. They become resigned to their situation and to the idea they can never feel better.  PGT is different and it can make a big difference in the lives of people with PG.  Some of the things that make it unique include that it’s,
