Prolonged Grief Disorder Treatment (PGDT/CGT)
Core Mechanism
Revisiting the death narrative integrates the reality of loss + imaginal conversations transform the continuing bond + restoration goals rebuild engagement with life
Ontology
Prolonged grief as a failure of natural adaptation: the attachment system cannot update to accommodate the permanence of loss, leaving the bereaved stuck between wanting the person back and knowing they are gone
Therapeutic Voice
"I'd like you to close your eyes and tell me the story of the day he died. Start a little before you knew, and tell it as though it's happening now, in the present tense. We'll go about ten minutes. I'm recording it so you can listen at home, and I'm right here the whole time."
View of the Person
An attached being whose internal working model cannot accommodate the permanence of loss, stuck in the liminal space between knowing and believing the person is gone
Origins & Influences
Shear published this protocol in 2005 as Complicated Grief Treatment (CGT), assembling it from three existing sources: interpersonal psychotherapy's attention to role transitions and interpersonal disputes, exposure procedures adapted from Foa's prolonged exposure for PTSD, and motivational interviewing's way of eliciting a client's own reasons to re-engage with life. The name changed when the diagnosis did. DSM-5-TR added Prolonged Grief Disorder in 2022, the protocol became Prolonged Grief Disorder Treatment, and Shear's Columbia center was renamed from the Center for Complicated Grief to the Center for Prolonged Grief. This is one protocol under two names, not two protocols. The randomized trials that support it were published as CGT, most clinicians trained before 2022 learned it as CGT, and the training program still lives at complicatedgrief.columbia.edu.
Evidence
APA: recognized for Prolonged Grief Disorder. VA/DoD: referenced in bereavement guidelines
Multiple RCTs (Shear et al., 2005, 2016) showing superiority to IPT for complicated grief
Included in Cochrane review of grief interventions; NNT ~4
The most strongly evidenced manualized protocol developed specifically for prolonged grief: Shear's own randomized trials in 2005 and 2016 both found it superior to interpersonal psychotherapy for this presentation. Shear's insight: complicated grief is essentially an attachment disorder: the bereaved person cannot update the internal working model to accommodate the loss. The revisiting exercises help integrate the reality of the death; the imaginal conversations help transform (not sever) the continuing bond. Dropout rates are lower than PE, likely because grief work feels more voluntary than fear exposure. Note that the supporting trial literature is published under the protocol's original name, Complicated Grief Treatment, so CGT and PGDT index one body of evidence rather than two competing protocols.
Conditions
Epistemology
Blind Spots
Revisiting exercises may feel coercive for clients whose culture doesn't value explicit grief narration; the highly structured protocol may not suit every grieving style; much less evidence for non-death losses than for bereavement; 16-session format may be insufficient for losses compounded by other traumas; PGD diagnosis itself is debated as potentially pathologizing normal grief
Contraindications
Active psychosis, acute suicidality, severe comorbid conditions requiring separate treatment first, clients in the early weeks of bereavement (the model addresses prolonged grief, not acute grief, and early bereavement has not yet had time to show whether grief will become prolonged), grief that is adaptive rather than clinically complicated, active substance dependence

How does PGDT differ from general grief counseling?
Show answer
PGDT is a manualized 16-session protocol specifically for Prolonged Grief Disorder (now in DSM-5-TR). It integrates elements of interpersonal psychotherapy, exposure procedures adapted from prolonged exposure, and motivational interviewing. The key components: a grief monitoring diary, revisiting the story of the death, situational revisiting of avoided places and activities, imaginal conversations with the deceased (continuing bonds), and explicit restoration goals. General grief counseling does not typically include exposure-based revisiting of the death narrative.
