Grief is not a disorder. Decades of bereavement research — most notably George Bonanno's longitudinal studies — show that the majority of bereaved people adapt over time through their own resilience and natural support systems, without professional treatment. This is worth stating plainly, because it shapes what good grief therapy looks like: a skilled grief therapist knows when therapy is genuinely indicated, and does not pathologize a normal human process.
At the same time, a meaningful minority of bereaved people — approximately one in ten, according to a 2017 meta-analysis by Lundorff and colleagues — develop what the DSM-5-TR now recognizes as Prolonged Grief Disorder (PGD): grief that remains intensely preoccupying and functionally impairing a year or more after the loss. PGD responds to specific, targeted treatment, and research shows that generic supportive counseling is measurably less effective for it. This is where grief-specific training matters most.
Prolonged Grief Disorder Therapy (also studied as Complicated Grief Treatment), developed by M. Katherine Shear, is a 16-session structured protocol combining elements of attachment theory, exposure, and interpersonal therapy. In randomized trials published in JAMA and JAMA Psychiatry (2005 and 2014), it produced roughly twice the response rate of standard interpersonal psychotherapy for people with prolonged grief, and a third trial (2016) found that it improved outcomes over antidepressant medication, which alone was no more effective than placebo for grief symptoms. The DSM-5-TR formally added Prolonged Grief Disorder as a diagnosis in 2022.
When grief therapy is worth seeking
Therapy can be valuable at any point in bereavement — for support, for meaning-making, or simply for a place to speak freely. But the research draws a useful distinction. In the early months of typical grief, structured intervention has not been shown to speed adaptation; presence, support, and time do most of the work. When grief remains dominating — persistent yearning, identity disruption, avoidance of reminders, inability to re-engage with life a year or more out — that pattern has a name, and it has a treatment. Losses by suicide, overdose, sudden accident, or the death of a child carry elevated risk for both prolonged grief and co-occurring PTSD or depression.
What grief-specific expertise looks like
They can distinguish typical grief from prolonged grief disorder
A grief specialist can describe the difference between acute grief, integrated grief, and prolonged grief disorder, and uses validated screening tools — such as the Inventory of Complicated Grief or the PG-13 — rather than treating all bereavement identically. They can also assess for co-occurring depression and PTSD, which have their own evidence-based treatments and frequently accompany traumatic loss.
Training in a structured grief protocol
For prolonged grief, ask about training in Prolonged Grief Disorder Therapy / Complicated Grief Treatment (Columbia's Center for Prolonged Grief offers formal training) or grief-focused cognitive behavioral approaches with trial support. A therapist who treats prolonged grief exclusively through open-ended supportive conversation is not using the interventions with the strongest evidence for that condition.
They do not impose a timeline or a stage model
The five-stages model remains culturally popular, but bereavement research does not support fixed stages that grievers should move through in order. A well-trained grief therapist neither rushes grief nor prescribes how it should look — and equally, does not dismiss impairing, persistent grief as something that only needs more time. Both errors come from the same place: treating grief as one thing.
Experience with your kind of loss
Suicide loss, overdose loss, pregnancy and infant loss, and the death of a child each carry distinct clinical features — stigma, guilt structures, trauma overlap — that shape treatment. Ask whether the therapist has worked with your specific type of loss and how their approach accounts for it. Where trauma symptoms are prominent, familiarity with trauma-focused protocols (or a clear referral relationship for them) matters.
Questions to ask a prospective grief therapist
- "How do you distinguish typical grief from prolonged grief disorder, and do you use a screening tool?"
- "What training have you completed in structured grief treatments specifically?"
- "Have you worked with losses like mine — and how does that change your approach?"
- "How do you handle grief that overlaps with trauma symptoms or depression?"
- "What does treatment look like with you — structure, length, and goals?"
- "How will we know it's helping?"
