Most grief does not require treatment, and that is genuinely good news. The great majority of bereaved people move, unevenly and over a long time, toward a life that accommodates the loss — carried by family, community, faith, and time. The bereavement research bears this out: benefit shows up most clearly when support is matched to the people who are struggling, rather than offered uniformly to everyone.

A minority, however, develop something distinct and persistent. Prolonged grief disorder was added to the DSM-5-TR in 2022 and appears in the ICD-11, and it responds to a specific treatment that general supportive counseling does not replicate.

What distinguishes it

The DSM-5-TR criteria require that the death occurred at least twelve months ago for adults — six months for children and adolescents — and that intense yearning for the deceased, or preoccupation with thoughts and memories of them, has been present nearly every day for at least the last month.

Alongside that, at least three of eight additional symptoms are required, including a marked sense of disbelief, avoidance of reminders, intense emotional pain, difficulty re-engaging with life, emotional numbness, a feeling that life is meaningless, intense loneliness, and disruption of identity — a sense that part of oneself has died. The symptoms must exceed cultural and religious norms for the person's context, and cause clinically significant distress or impairment.

That cultural clause is not boilerplate. Mourning practices, expected duration, and expressions of continued connection to the dead vary enormously across communities, so a clinician who understands your cultural and religious context is far better placed to tell ordinary mourning from grief that has become stuck.

What the Research Shows

Katherine Shear's Complicated Grief Treatment — a sixteen-session protocol drawing on elements of interpersonal therapy, motivational interviewing, and exposure — has been tested in multiple randomized controlled trials. It has consistently outperformed interpersonal psychotherapy, with response rates roughly doubling in some trials, and it also outperformed medication delivered alone.

Estimates of prevalence among bereaved adults generally fall around seven to ten percent, with substantially higher rates following violent or sudden death, the death of a child, and loss by suicide.

What treatment involves

01

Psychoeducation about grief itself

Treatment usually begins with a model of adaptive grieving — not as a sequence of stages, which the research does not support, but as an oscillation between engaging with the loss and engaging with ongoing life. Many people find that naming this oscillation relieves the sense that they are grieving incorrectly.

02

Restoring forward-looking goals

A distinctive feature of the protocol is that work on personal goals begins early rather than after the grief has been processed. Clients identify what they would want for themselves if the pain were less — and begin acting on it in parallel with the grief work.

03

Revisiting the story of the death

An exposure component: recounting the death in detail, often recorded and listened to between sessions, in graduated form. This targets the avoidance that keeps the loss unassimilated, and closely parallels the mechanism in trauma-focused treatment.

04

Approaching avoided situations

Systematically re-entering the places, people, objects, and dates that have been avoided — the room, the restaurant, the anniversary, the photographs.

05

An imagined conversation

A structured exercise in which the person speaks to the deceased and voices what the deceased might say in return. Frequently one of the most affecting sessions in the protocol, and a common turning point.

06

Rebuilding the connection in a new form

Not letting go — the model explicitly rejects severing the bond — but moving from a relationship organized around absence to one organized around memory.

The goal is not to stop missing them. It is to be able to hold the loss and still have a life running alongside it.

What to look for

Ask directly whether the clinician has training in a grief-specific protocol — Complicated Grief Treatment, or one of the CBT-based approaches developed for prolonged grief. Where prolonged grief is present, these targeted protocols are where the strongest outcome evidence sits, and clinicians trained in them can tell you exactly what the sessions will involve.

Also worth asking about: whether they screen for prolonged grief with a validated measure such as the PG-13-R, and whether they assess for co-occurring depression and PTSD, both of which are common after bereavement and both of which have their own treatments. And any clinician working with bereavement should be assessing suicide risk directly and repeatedly.
