Traumatic Grief as Distinct Disorder: A Rationale, Consensus Criteria, and a Preliminary Empirical Test

13 important questions on Traumatic Grief as Distinct Disorder: A Rationale, Consensus Criteria, and a Preliminary Empirical Test

Symptoms of Traumatic Grief are ____ bereavement-related depression or anxiety

distinct from

Robins and Guze's (1970) taxonomic principles (5)

1. the provision of a clinical description of the disorder
2. laboratory studies that define the disorder
3. the delimitation of the proposed disorder from other disorders
4. follow-up studies of the disorder
5. family studies of disorder

Empirical evidence strongly supports unity among proposed TG symptoms however they can be conceptualized as falling into two categories

1) symptoms of separation distress (preoccupation with thoughts of the deceased to the point of functional impairment, upsetting memories about deceased, longing and searching for deceased, loneliness following the loss.
2) symptoms of traumatic distress (feeling of disbelief, mistrust, anger, and detachment from others, feeling shocked, experience of somatic symptoms of deceased)

Why the name Traumatic Grief (TG) and not Complicated Grief (CG)?

- CG is vague, could refer to any of several symptoms of distress
- Other adjectives such as pathologic, neurotic, distorted etc. seemed derogatory and value-laden
- consider Grief reaction to be a stress response syndrome (similar symptoms to PTSD)
- appears to be a 'separation trauma'

Why is there resistance to include TG as distinct diagnostic category?

because TG might be argued to be able to be subsumed by already established psychiatric disorders (MDD, AD, PTSD)

Major Depressive Disorder (MDD) vs. TG

- distinct symptom cluster apart from symptoms of depression
- predict wide variety of mental and physical health disorders adjusting for and separate from the outcomes associated with depression
- have distinctive clinical course and response to DST
- distinct neurodocrine responses and responses to pharmacological treatment compared to those found for bereavement-related depression
- distinct EEG sleep profiles from MDD
- distinct risk factors from depression

Possible to meet TG criteria but be missed by MDD diagnosis

Adjustment Disorder (AD) vs. TG

- AD does not include the specific clinical features of TG described previously
- There is the stipulation that AD 'must resolve within 6 months of termination of the stressor' (TG symptomatology may last for years)
- Criterion D: symptoms cannot be a consequence of bereavement

Re-experiencing, avoidance, and hyper arousal differences in PTSD and TG

thoughts of the person rather than of the event;
avoidant thoughts and behaviours appear to be less central than the numbness and dissociative features of disorder;
hyper arousal related to searching for the missing loved one rather than being rooted in threat posed by dangerous event

Clinical perspective of advantages of distinct TG category

uniform criteria would enable the accurate detection, treatment, and reimbursement for treatment of individuals with this disorder.

Research perspective of advantages of distinct TG category

studies of prevalence, risk factors, outcomes, neurobiology, prevention and treatment of TG have been hampered by the absence of standardized criteria

View by Prigerson and Jacobs on making TG distinct diagnostic entity:

they consider the cost of misdiagnosis to be off set by benefits of identifying and intervening on behalf of those who suffer from their grief the most
harm done by not diagnosing those at risk (false negatives) is a greater concern than the misdiagnosis of those who are grieving normally (false positives)

2 assessment tools for TG

- Traumatic Grief Evaluation of Response to Loss ( rater evaluated the frequency and intensity of each of the proposed symptoms and provides instructions for determining whether or not respondent would meet diagnostic for TG)
- Inventory of Traumatic Grief (provides self-report  symptoms severity score. Also includes instructions to assist raters in determining whether or not responses would meet thresholds required for diagnosis.)

Limitations of data used by Prigerson and Jacobs

- study group to test criteria was not entirely random or unbiased
- absence of information about nonparticipants
- items from Widowhood Questionnaire did not contain exact wording of proposed criteria (was scored on scale rather than present/not present)

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
