Prolonged Grief Disorder Assessment: Screening Tools and Referral Criteria for Hospice Workers

PGD Is Now a Formal Diagnosis — And That Changes Your Role

Prolonged Grief Disorder (PGD) entered the DSM-5-TR as a formal diagnosis (code F43.81) and is recognized in the ICD-11. For hospice bereavement workers, this matters practically. Before the DSM inclusion, identifying a bereaved person whose grief had become pathological was clinically important but diagnostically ambiguous — you could describe complicated grief, but there was no billable, widely accepted diagnostic category. Now there is.

This does not mean you are diagnosing PGD. Hospice bereavement coordinators, social workers, and chaplains screen for concerns. The diagnosis itself belongs to a licensed mental health professional qualified to conduct a full clinical evaluation. Your role is to recognize the warning signs early enough to refer.

The DSM-5-TR Diagnostic Criteria

The diagnostic threshold is precise. PGD requires:

Time criterion: The death of a close person occurred at least 12 months ago for adults (6 months for children and adolescents). This time gate is clinically important — it distinguishes PGD from acute grief, which is painful but normative. Screening at 12 months or later is when the diagnosis becomes applicable.

Core symptom: Intense separation distress — nearly daily, clinically significant yearning for the deceased or preoccupation with thoughts of the deceased — present for at least the last month.

Accessory symptoms (at least 3 of 8, present nearly every day for the past month):

1. Identity disruption — feeling as though a fundamental part of oneself has died
2. Marked disbelief about the reality of the death
3. Active avoidance of reminders that the person is dead
4. Intense emotional pain — pervasive anger, bitterness, or sorrow
5. Difficulty reintegrating — severe problems engaging with friends, interests, or plans
6. Emotional numbness — a marked reduction in emotional experience
7. Meaninglessness — life feels entirely unfulfilling without the deceased
8. Intense loneliness — feeling completely detached from others

Functional impairment: The symptoms cause severe distress or impairment in social, occupational, or daily functioning.

Exclusionary check: The grief reaction must clearly exceed expected social, cultural, or religious norms, and cannot be better explained by Major Depressive Disorder or PTSD.

Screening Tools for Hospice Settings

You do not need to administer a full diagnostic battery. You need tools that reliably flag individuals who warrant referral for formal evaluation.

The Adult Attitude to Grief (AAG) Scale with Index of Vulnerability (IOV). The AAG — already in use in many hospice bereavement programs — provides a quantifiable vulnerability score. The IOV is calculated from three subscales: Overwhelmed, Controlled, and Resilient. An IOV of 24 or higher indicates severe vulnerability and warrants direct therapeutic intervention by a licensed mental health professional. The AAG was not designed specifically as a PGD screener, but a severe-range score at a later milestone is a reason to refer for clinical evaluation.

The Prolonged Grief-13-Revised (PG-13-R). This self-report measure, developed by Holly Prigerson and colleagues, was revised to align with the DSM-5-TR criteria for PGD. Use the instrument's published instructions for administration and interpretation.

The Brief Grief Questionnaire (BGQ). A brief screening tool that may be used during hospice milestone check-ins. Use the instrument's validated scoring guidance rather than an assumed hospice-specific cutoff when deciding whether to refer for clinical evaluation.

The Inventory of Complicated Grief (ICG-R). An instrument that evaluates the severity of grief symptoms. Follow its published scoring guidance when considering clinical evaluation; do not treat a score alone as a diagnosis.

What Screening Looks Like at Each Milestone

Screening for PGD is not a single event — it is integrated into your milestone follow-up schedule.

Month 3 check-in: Too early for a PGD diagnosis, but watch for acute risk factors. Is the person showing signs of severe emotional flooding (AAG Overwhelmed subscale), complete emotional shutdown (Controlled subscale), or absence of any adaptive coping (low Resilient subscale)? Document your observations and any concerns.

Month 6 check-in: Administer a brief screening (BGQ or a clinical interview using the PGD symptom list). If the person's grief has not begun to shift — if they are as intensely distressed as they were at month 1, or if new symptoms have emerged — flag the case for enhanced monitoring.

Month 9 check-in: Anticipatory anxiety about the approaching anniversary often intensifies grief. This is expected. But if the person is exhibiting identity disruption, persistent avoidance, or emotional numbness at this stage, the trajectory is concerning.

Month 12–13 check-in: For adults, this is the earliest point at which the DSM-5-TR time criterion for PGD can be met. A screening result or clinical concern should prompt referral for formal evaluation by a licensed mental health professional; screening tools do not establish the diagnosis.

Making the Referral

The referral conversation requires clinical sensitivity. Telling a bereaved person "your grief might be a disorder" can feel invalidating if handled poorly. Frame it around their experience, not a diagnosis:

"You've told me that the pain is just as intense now as it was a year ago, and that you're finding it hard to do things you used to enjoy. That kind of persistent intensity is something that a grief specialist can really help with — not because there's anything wrong with how you're grieving, but because there are specific therapeutic approaches that can make this more bearable."

Refer to clinicians who specialize in grief and loss — ideally someone trained in grief-focused cognitive behavioral therapy or prolonged grief disorder treatment. Generic therapists may not be equipped for the specific clinical features of PGD.

Document the referral in the bereavement chart: who you referred, to whom, on what date, the clinical basis for the referral, and the family member's response.

The Hospice Worker's Family Bereavement Support Toolkit includes the clinical risk assessment framework — AAG scoring with IOV interpretation, referral criteria matrices, and escalation decision trees — that connects your milestone screening to actionable clinical pathways.
