Prolonged Grief Disorder Treatment (PGDT/CGT)
Prolonged Grief Disorder Treatment (PGDT/CGT) is an integrative psychotherapy developed by M. Katherine Shear in 2005. Its core mechanism: revisiting the death narrative integrates the reality of loss, imaginal conversations transform the continuing bond and restoration goals rebuild engagement with life. This catalogue links it to grief and loss, typically in individual format, 16 sessions.

How Prolonged Grief Disorder Treatment works
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

Condition-specific assessments
Each conclusion applies to the population and use described. These source-based assessments do not certify the full entry or replace expert clinical review.
Grief & Loss
Population and scope: Bereaved adults aged 18–95 with clinically primary complicated grief in the 2016 trial; 16-session CGT added to placebo plus structured clinical management.
Randomized studies
Shear et al. (2016) randomized 395 adults to citalopram or placebo, with or without CGT. At 20 weeks, CGT plus placebo improved grief-response rates compared with placebo plus clinical management. Adding citalopram did not significantly improve the grief-response outcome, although depressive symptoms improved. This was not an IPT comparison. Missing assessments remained a limitation despite statistical adjustment; the sample was predominantly White, female and well educated. The historical complicated-grief criteria are not identical to current PGD criteria. Findings do not grade routine early bereavement, every grief therapy or suicide prevention.

Discussed in the source
The association discusses prolonged-grief therapy in patient information. This is distinct from a clinical practice guideline, and DSM recognition of the diagnosis is not treatment endorsement.
Scope: Information about prolonged grief disorder and treatment approaches.
Recorded material under review
The existing notes below are retained separately from assessment records. These recorded claims await source checking, including study design, recommendations and numerical estimates.
Randomized CGT research includes Shear et al. (2016), a four-arm trial of citalopram/placebo with and without CGT. It did not compare CGT with IPT. A complete count of independent trials has not been verified in this review. Its introduction cites earlier trials comparing CGT with grief-focused IPT; those earlier trials were not retrieved and rechecked in this pass.
Sources for the corrected statements:
This pass checked an original CGT trial, not a systematic review. Its grief-response estimates must not be attributed to an unverified Cochrane review.
Sources for the corrected statements:
The 2016 four-arm trial supports adding the tested CGT protocol to placebo plus medication-management visits providing psychoeducation, grief monitoring and encouragement of activity for adults with complicated grief. It did not compare CGT with IPT or prolonged exposure. This review does not verify the prior claim of lower dropout than PE or a causal explanation for that comparison. The scoped assessment records measured outcomes and limitations; the study used the historical Complicated Grief Treatment name. Earlier IPT-comparison trials cited in the introduction remain outside this bounded trial check.

Equity & Cultural Adaptations
Clinical cautions and blind spots
Assessment and precautions
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
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
Philosophical roots
Bowlby (attachment); Shear (complicated grief as attachment disorder); Foa (emotional processing applied to grief); Klass & Silverman (continuing bonds); Stroebe & Schut (dual process model, source of the loss-oriented and restoration-oriented halves of the protocol); Worden (task model of mourning); DSM-5-TR nosology
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.

Each vignette presents the same client through multiple theoretical lenses side by side — showing how Prolonged Grief Disorder Treatment (PGDT/CGT) formulates presenting problems, sets treatment focus, and sounds in the consulting room compared with the other modalities working the same 2 cases. This comparative pedagogy is unique to Epoché Clinical; no other clinical reference systematically formulates the same case across traditions.

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.
