Prolonged grief disorder in ICD-11 and DSM-5-TR: Challenges and controversies

Prolonged grief disorder has recently been added to the International Classification of Diseases, 11th edition and the Diagnostic and Statistical Manual of Mental Disorders 5, Text Revision. This historical development is often presented as a linear process culminating in the inclusion of valid, clinically relevant prolonged grief disorder criteria in diagnostic handbooks. The present contribution provides an overview of work contradicting this dominant narrative. First, I show that the developmental history of prolonged grief disorder has been nonlinear and that this yields questions on generalizability and problems with measurement of the newest criteria sets. Second, I highlight an important gap in the validity evidence: the distinction of prolonged grief disorder from normal grief. Third, I discuss concerns relating to the societal effects of the inclusion of prolonged grief disorder in diagnostic handbooks, including the medicalization of grief, development and adverse effects of pharmacotherapy and stigmatization. A more realistic, balanced view on the history, validity and societal impact of prolonged grief disorder appears appropriate. I recommend stringent validation of assessment instruments for prolonged grief disorder, convergence of criteria-sets, closing gaps in validity evidence and developing strategies to mitigate the negative effects of grief diagnoses.

Are deaths from COVID-19 associated with higher rates of prolonged grief disorder (PGD) than deaths from other causes?

With the COVID-19 pandemic prompting predictions of a "grief pandemic," rates and risks for Prolonged Grief Disorder (PGD) warrant further investigation. Data were collected online from 1470 respondents between October 2020 and July 2021. Shorter time since death, deaths of siblings and "others," and deaths from accidents and homicides were positively associated with potential risk of probable PGD; deaths of extended family and from dementia were negatively associated with probable PGD. When compared directly to deaths from COVID-19, natural causes of death were associated with lower potential risk of probable PGD, while deaths from unnatural causes were associated with higher potential risk.

Rates of Prolonged Grief Disorder: Considering relationship to the person who died and cause of death

BACKGROUND

Prolonged Grief Disorder (PGD) was recently included in DSM-5-TR. The rate of PGD is known to vary according to a number of factors and little is known about how bereaved individuals view the diagnosis.

METHODS

This cross-sectional study assessed PGD rates using the Prolonged Grief-13-Revised (PG-13-R) among a large sample (n = 1137) of bereaved individuals, considering the relationship to the deceased and cause of death. It also investigated bereaved individuals' attitudes toward the diagnosis.

RESULTS

Overall, 34.3 % of the sample met PGD criteria. Bereaved parents had the highest rate (41.6 %), followed by bereaved spouses/partners (33.7 %) and siblings (29.4 %). According to cause of death, those bereaved by substance overdose had the highest rate (59.1 %), followed by homicide/suicide (46 %) and accidental (36 %). The majority of respondents (65-95.6 %) viewed their responses, as measured by the PG-13-R items, as normal, and 98.1 % agreed that their responses in general were normal. Fewer than 12 % reported that a PGD diagnosis would be helpful to them.

LIMITATIONS

This study used a self-selecting, non-representative sample that was predominantly female and white. Findings may or may not apply to more diverse groups and cannot be generalized. This study also used a self-report measure rather than a clinical interview.

CONCLUSIONS

In line with prior research, this study found higher rates of PGD in specific subgroups, including bereaved parents, spouses, and those who lost loved ones to substance overdose, homicide/suicide, or accidents. Bereaved individuals in this sample generally did not view receiving a diagnosis of PGD as helpful.

Validation of the prolonged grief scale (PG-13) and investigation of the prevalence and risk factors of prolonged grief disorder in Turkish bereaved samples

The aim of this study was to validate the Turkish version of the Prolonged Grief Scale (PG-13) and to determine the prevalence and predictors of prolonged grief disorder (PGD). Data were gathered from two independent samples of 306 (Study 1) and 271 (Study 2) bereaved adults to determine if findings in one sample could be replicated in the other. The results supported the one-factor structure of PG-13. PGD prevalence rates were 11.4% in Study 1 and 10% in Study 2. Lower level meaning reconstruction and unnatural cause of death were found as risk factors for the PGD diagnosis in both studies.

Public Stigma of Prolonged Grief Disorder: An Experimental Replication and Extension

ABSTRACT

Prolonged grief disorder's (PGD's) recent recognition as a psychiatric diagnosis has elicited concerns about stigmatization. Although prior research demonstrated that PGD elicits public stigma, moderators of this effect are unclear, and the effect requires replication in an English-speaking population. Therefore, we investigated the effects of PGD, sex of the bereaved, and death expectedness on public stigma toward bereaved persons. We randomly assigned 195 Australian adults (77% female; mean age, 35.7 years) to read one of eight vignettes describing a bereaved male or female subject, with or without PGD, after an expected or unexpected death. Participants reported their emotional reactions and negative attributions toward, and desired social distance from, the bereaved person. A person with PGD (vs. without) elicited stronger emotional reactions, negative attributions, and desired social distance. No robust moderator effects emerged. Results validate concerns that PGD causes stigma. Stigmatization may be targeted by information campaigns or psychological treatment.

Prevalence of prolonged grief disorder and its symptoms in Chinese parents who lost their only child: A systematic review and meta-analysis

BACKGROUND

Parents who lost their only child and cannot have a second child ("Shidu") have been a large population in China. Prolonged grief disorder (PGD) in Shidu parents is of clinical and public health concern but the reported PGD prevalence varies widely. To facilitate the planning of grief counseling services, this meta-analysis estimated prevalence of PGD and its symptoms and identified subgroups at elevated risk for PGD.

METHODS

We searched English and Chinese literature databases to identify cross-sectional surveys reporting prevalence of PGD or PGD symptoms in Chinese Shidu parents. The Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data ("JBI") was used to assess risk of bias of included studies.

RESULTS

Seven studies with a total of 2,794 Shidu parents were included and their JBI scores ranged from five to eight. The pooled prevalence of PGD and PGD symptoms was 20.9% and 75.0%, respectively. Greater risk of PGD was observed in mothers [vs. fathers, OR (odds ratio) = 1.89, P = 0.001] and in parents with religious beliefs (vs. without religious beliefs, OR = 1.65, P = 0.040). More severe PGD symptoms were presented in parents whose only child died from accidents [vs. illness, MD (mean difference) = 3.99, P < 0.001]. Deceased children of PGD parents were older than those of non-PGD parents (MD = 1.64, P = 0.035) and PGD parents had a shorter duration since the loss than non-PGD parents (MD = -3.26, P = 0.013).

CONCLUSIONS

PGD is prevalent among Shidu parents. Grief counseling services for Shidu parents would be more effective if they target those who are mothers and have religious beliefs and those whose children died from accidents, lost children are older, and loss occurs more recently.

Network analysis of PGD, PTSD and insomnia symptoms in Chinese shidu parents with PGD

Background

Chinese shidu parents (bereaved parents over the age of 49 who have lost their only child) are potentially at a high risk of prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD) and insomnia.

Objective

The current study aimed to estimate three network models in 310 shidu parents who met the ICD-11 criteria for PGD: (1) a PGD network to identify central symptoms; (2) a comorbidity network to explore bridge symptoms between PGD and PTSD; (3) a comorbidity network to examine the associations between PGD and insomnia symptoms.

Methods

The R-packages bootnet, qgraph and networktools were used to investigate the structure of network models and centrality indices of symptoms. In addition, robustness and significance analyses for the edge weights and the order of centrality were performed.

Results

Emotional pain and numbness emerged as the most central symptoms in the PGD network. In the PGD-PTSD comorbidity network, the highest bridge strength symptoms were inability to trust others (PGD) and feeling upset (PTSD). Inability to trust others (PGD), avoidance (PGD), and impairment of life quality (insomnia) were possible bridge symptoms connecting PGD and insomnia.

Conclusions

Reducing emotional pain and numbness may be a viable target in PGD interventions for shidu parents. Additionally, findings suggest that future studies could examine the role of inability to trust others and avoidance in PGD comorbidities.

HIGHLIGHTS

• Emotional pain and numbness were the most influential symptoms in shidu parents with PGD. The role of PGD symptoms of inability to trust others and avoidance in the comorbidities of PGD with PTSD and insomnia might be worthy of further study.

Cross-national analysis of the prevalence of prolonged grief disorder

BACKGROUND

Prolonged grief disorder (PGD) is now included as a diagnosis in international classification systems. Most research on PGD is based on Western populations, but first data from non-Western countries have recently become available. Little is still known about country-related effects on PGD's prevalence.

OBJECTIVE

Determining possible causes of variations in the prevalence of PGD as defined by DSM-5-TR and ICD-11 within and between countries.

METHODS

We retrieved data from 24 prevalence studies, the World Bank and the 2022 World Risk Report. Negative binomial regressions were used to explore methodological, loss-related and country context characteristics as predictors of PGD. The average rate of PGD was calculated using random effects models.

RESULTS

The included studies comprised 34 samples from 16 countries (20,347 participants). Non-probability sampling and older mean age of the sample as well as lower country vulnerability were associated with higher PGD rates. The average PGD prevalence was 13 % (95 % CI [11, 22]), varying from 5 % (95 % CI [3, 11]) in probability to 16 % (95 % CI [13, 25]) in non-probability samples.

LIMITATIONS

Samples from Europe and North America were overrepresented. For about half of the countries, data were available from only one sample.

CONCLUSIONS

While confirming the importance of studies' methodological quality, the results show that PGD is of public health relevance around the world, but especially common in less vulnerabled countries with better access to daily necessities and healthcare services, highlighting sociocultural impacts on grief processing. Further investigations of cross-national differences are needed.

The brain oxytocin and corticotropin-releasing factor systems in grieving mothers: What we know and what we need to learn

The bond between a mother and her child is the strongest bond in nature. Consequently, the loss of a child is one of the most stressful and traumatic life events that causes Prolonged Grief Disorder in up to 94 % of bereaved parents. While both parents are affected, mothers are of higher risk to develop mental health complications; yet, very little research has been done to understand the impact of the loss of a child, stillbirth and pregnancy loss on key neurobiological systems. The emotional impact of losing a child, e.g., Prolonged Grief Disorder, is likely accompanied by dysregulations in neural systems important for mental health. Among those are the neuropeptides contributing to attachment and stress processing. In this review, we present evidence for the involvement of the brain oxytocin (OXT) and corticotropin-releasing factor (CRF) systems, which both play a role in maternal behavior and the stress response, in the neurobiology of grief in mothers from a behavioral and molecular point of view. We will draw conclusions from reviewing relevant animal and human studies. However, the paucity of research on the tragic end to an integral bond in a female's life calls for the need and responsibility to conduct further studies on mothers experiencing the loss of a child both in the clinic and in appropriate animal models.

Symptoms and levels of ICD-11 Prolonged Grief Disorder in a representative community sample of UK adults

BACKGROUND

Prolonged Grief Disorder (PGD) is a new disorder included in ICD-11 (WHO, 2018). There is a growing body of literature surrounding the prevalence and correlates of ICD-11 PGD symptoms as assessed using various measures. This study was the first to assess levels of ICD-11 PGD symptoms as measured by the International Prolonged Grief Disorder Scale (IPGDS), a self-report scale directly aligned with the ICD-11 definition of PGD, among the United Kingdom adult general population, and identify correlates.

METHOD

Participants included 2025 adults who participated in Wave 5 of the COVID-19 Psychological Research Consortium Study (C19PRC-UK). Prevalence rates of PGD were estimated based on two commonly used algorithms defined as 'strict' and 'moderate'. Sociodemographic, loss-related, and mental health correlates (i.e., anxiety, depression, mental health treatment seeking, loneliness) of strict and moderate PGD were then examined using multinomial logistic regressions.

RESULTS

It was found that 2.4% (n = 43) of participants met probable caseness for PGD using the strict criteria while 7.9% (n = 140) met probable caseness for PGD using the moderate criteria. Multinomial logistic regression analysis results showed, as predicted, that income, time since bereavement, death of a child, religiosity, and depression were associated with both moderate and strict PGD. Correlates of moderate PGD included country of residence, urbanicity, younger age of bereaved, and loneliness.

CONCLUSIONS

This study highlights that some symptoms of PGD are commonly reported in the general population, although relatively few meet the criteria for clinical significance. The routine assessment for PGD following a bereavement is discussed and the development of appropriate interventions are recommended.

Psychometric properties of the PG-13-R scale to assess prolonged grief disorder among bereaved Iranian adults

OBJECTIVES

The PG-13-Revised (PG-13-R) is a self-report measure to assess prolonged grief disorder (PGD) in terms of Diagnostic and Statistical Manual of Mental Disorders, fifth revision, Text Revision. This measure has been shown to yield good psychometric properties in Western samples. This study aimed to evaluate the psychometric properties of the Persian PG-13-R.

METHODS

Three hundred forty-seven individuals (209 women and 138 men) fully completed the scales. The participants were recruited using convenience sampling. The confirmatory factor analysis (CFA), convergent and divergent validity, and reliability of the Persian version of the PG-13-R were evaluated.

RESULTS

CFA results of a unidimensional model support the construct validity of this version of the PG-13-R. The results of this study demonstrated that this version of the PG-13-R has internal consistency reliability (omega coefficient of 0.93), and the test-retest reliability with an interval of 6 weeks was 0.89. The convergent and divergent validity was shown with significant correlations between the PG-13-R and measures of depression, PTSD, functional impairment, and hope.

SIGNIFICANCE OF RESULTS

Overall, the Persian version of the PG-13-R showed good psychometric properties in the Iranian population.

Prolonged grief disorder among bereaved survivors after the 2011 Van Earthquake in Turkey

The aim of the current study was to investigate the ratio and predictors of probable Prolonged Grief Disorder (PGD) among bereaved survivors eight years after the 2011 Van earthquake. Among a sample of 495 survivors who experienced loss as a result of this earthquake, 8.9% met the criteria of probable PGD. In the binary logistic regression analysis, being woman, being aged 40 or over, personal injury, property damage, losing family members, and the psychological impact of the earthquake predicted probable PGD. The current study highlights the importance of considering PGD among bereaved survivors after earthquakes.

Prolonged Grief Disorder: Addressing Misconceptions With Evidence

There are many misconceptions about Prolonged Grief Disorder (PGD). We show with data that PGD is a diagnosis that applies to a rare few of mourners who are at risk of significant distress and dysfunction. Those mourners who meet criteria for PGD have been shown to benefit from specialized, targeted treatment for it. The case against PGD is empirically unsubstantiated, and the need for scientific examination of effective treatments is warranted.

The International Grief Questionnaire (IGQ): A new measure of ICD-11 prolonged grief disorder

Prolonged grief disorder (PGD) is included in the 11th version of the International Statistical Classification of Diseases and Related Health Problems (ICD-11). This study sought to test the validity and reliability of a new brief measure to screen for ICD-11 PGD-the International Grief Questionnaire (IGQ). The psychometric properties of the IGQ were tested using data collected from two bereaved samples of adults from the United Kingdom (n = 1,012) and Ireland (n = 1,011). Confirmatory factor analysis demonstrated that a correlated two-factor model best captured the latent dimensionality of the IGQ in both samples. Estimates of internal reliability were high, whereas the convergent and concurrent validity of the scale were supported through strong associations with external measures. Measurement invariance and differential item functioning testing showed no statistically significant difference in the latent structure of the IGQ nor the functioning of the IGQ items by age, sex, and nationality. For participants who were bereaved for more than 6 months, the rates of probable PGD derived from the IGQ were 10.9% and 15.3% for the Irish and U.K. samples, respectively. The IGQ is a brief, easy-to-use, self-report screening measure that captures all diagnostic criteria of PGD set forth in the ICD-11. Findings from this study provide initial support for the validity, measurement invariance, and reliability of the IGQ among two national samples.

Prevalence, Correlates, and Psychiatric Burden of Prolonged Grief Disorder in U.S. Military Veterans: Results From a Nationally Representative Study

OBJECTIVES

To examine the point prevalence and correlates of prolonged grief disorder (PGD) in a nationally-representative sample of United States (U.S.) veterans.

METHODS

Data were analyzed from the National Health and Resilience in Veterans Study, a nationally representative study of 2,441 U.S. veterans.

RESULTS

A total of 158 (weighted 7.3%) veterans screened positive for PGD. The strongest correlates of PGD were adverse childhood experiences, female sex, non-natural causes of death, knowing someone who died from coronavirus disease 2019, and number of close losses. After adjusting for sociodemographic, military, and trauma variables, veterans with PGD were 5-to-9 times more likely to screen positive for post-traumatic stress disorder, major depressive disorder, and generalized anxiety disorder. After additional adjustment for current psychiatric and substance use disorders, they were 2-3 times more likely to endorse suicidal thoughts and behaviors.

CONCLUSIONS

Results underscore the importance of targeting PGD as an independent risk factor for psychiatric disorders and suicide risk.

ICD-11 prolonged grief disorder: Prevalence, predictors, and co-occurrence in a large representative sample

The International Classification of Diseases has recently defined Prolonged Grief Disorder (PGD) with symptoms such as longing, worry, and intense emotional pain that exceed sociocultural norms more than 6 months after the loss. This study aims to (a) estimate the prevalence of this new diagnostic category, (b) identify its sociodemographic and loss-related predictors, and (c) assess the co-occurrence of PGD with other psychological disorders and substance abuse. A large representative sample of Spanish adults (N = 1498) participated. Several multivariate binary logistic regression and multivariate logistic regression models were used. Results showed a 9.95% prevalence in the total sample. Catholic beliefs were a positive predictor, while higher income and more time since loss significantly decreased the odds of PGD. PGD significantly increased the likelihood of anxiety, depression, somatisation, post-traumatic stress disorder, loneliness and substance use. Our study contributes to assessing the multicultural PGD validity, as our results from a large representative sample are comparable to those in other countries with the PGDS. Our findings have direct implications for the assessment and treatment of bereavement, identifying for practitioners variables that make individuals more vulnerable to PGD. Results highlighted the high co-occurrence of PGD with other psychological illnesses and increased drug use.

The Traumatic Grief Inventory-Clinician Administered: A psychometric evaluation of a new interview for ICD-11 and DSM-5-TR prolonged grief disorder severity and probable caseness

BACKGROUND

There is a need for an interview-based measure to assess Prolonged Grief Disorder (PGD) included in the text revision of the fifth Diagnostic and Statistical Manual for Mental Disorder (DSM-5-TR) and 11th edition of the International Classification of Disease (ICD-11). We evaluated the psychometric properties of the Traumatic Grief Inventory-Clinician Administered (TGI-CA); a new interview measuring DSM-5-TR and ICD-11 PGD severity and probable caseness.

METHODS

In 211 Dutch and 222 German bereaved adults, the: (i) factor structure, (ii) internal consistency, (iii) test-retest reliability, (iv) measurement invariance across subgroups (e.g., differing in language), (v) prevalence of probable caseness, (vi) convergent validity, and (vii) known-groups validity were examined.

RESULTS

Confirmatory factor analyses (CFAs) showed acceptable fit for the unidimensional model for DSM-5-TR and ICD-11 PGD. Omega values indicated good internal consistency. Test-retest reliability was high. Multi-group CFAs demonstrated configural and metric invariance for DSM-5-TR and ICD-11 PGD criteria for all group-comparisons; for some we found support for scalar invariance. Rates of probable caseness for DSM-5-TR PGD were lower than ICD-11 PGD. Optimal agreement in probable caseness was reached when increasing the number of accessory symptoms for ICD-11 PGD from 1+ to 3+. Convergent and known-groups validity was demonstrated for both criteria-sets.

LIMITATIONS

The TGI-CA was developed to assess PGD severity and probable caseness. Clinical diagnostic interviews for PGD are needed.

CONCLUSIONS

The TGI-CA seems a reliable and valid interview for DSM-5-TR and ICD-11 PGD symptomatology. More research in larger and more diverse samples is needed to further test its psychometric properties.

Coping strategies as a causal mediator of the effect of loss-related memory characteristics and negative loss-related appraisals on symptoms of PGD, PTSD and depression

BACKGROUND

Psychological models of posttraumatic stress disorder (PTSD) and prolonged grief disorder (PGD) make predictions about the role of unhelpful coping strategies in maintaining difficulties by blocking self-correction of negative appraisals and memory integration following stressful life events like bereavement. However, few studies have tested these predictions directly.

METHOD

We used counterfactually based causal mediation to assess whether unhelpful coping strategies mediated the relationship between (1) loss-related memory characteristics and/or (2) negative grief-related appraisals and symptoms of PGD, PTSD and depression using a three-wave longitudinal sample (N = 275). Appraisals and memory characteristics were measured at time point 1, unhelpful coping strategies at T2, and symptom variables at T3. Additionally, multiple mediation analyses within a structural equation modelling (SEM) framework assessed which types of coping strategies differentially mediated symptoms of PGD, PTSD and depression.

RESULTS

Coping strategies mediated the relationship between negative appraisals and memory characteristics and symptoms of PGD, PTSD and depression after adjusting for demographics and loss characteristics. Sensitivity analyses suggested that these results were most robust for PGD, followed by PTSD and then depression. Multiple mediation analyses suggested that all four subscales (avoidance, proximity seeking, loss rumination and injustice rumination) individually mediated the effect of memory characteristics and appraisals on PGD.

CONCLUSIONS

These results suggest that core predictions of the cognitive model for PTSD and the cognitive behavioural model of PGD are useful in predicting symptoms of post-loss mental health problems in the first 12-18 months after loss. Targeting unhelpful coping strategies is likely to reduce symptoms of PGD, PTSD and depression.

Testing the latent structure of ICD-11 prolonged grief disorder symptoms in the U.K. adult population: An exploratory structural equation modeling approach

The latent structure of ICD-11 prolonged grief disorder (PGD), as measured using the International Prolonged Grief Disorder Scale (IPGDS), was assessed in a large general population sample of bereaved adults from the United Kingdom. Data were derived from Wave 5 of the COVID-19 Psychological Research Consortium Study (C19PRC-UK). Exploratory structural equation modeling (ESEM) was used to assess the latent structure of the IPGDS. Identified factors were explored in relation to known correlates (i.e., gender, age of the bereaved, income, bereavement timeframe, age of the deceased) and functional impairment. Three factors-Loss, Emotional Numbing, and Emotional Reactivity-emerged in the best-fitting ESEM model, χ2 (92, N = 1,763) = 273.70, p < .001, CFI = .97, TLI = .96, RMSEA = .048, SRMR = .020. All factors were significantly associated with bereavement timeframe, βs = -.15--.20, and age of the deceased, βs = -.22--.31. Lower income predicted both Loss and Emotional Numbing; younger age of the bereaved predicted both Loss and Emotional Reactivity; and female gender was a unique predictor of Loss. Functional impairment was associated only with Emotional Numbing, β = .89. The findings highlight the multidimensional structure of PGD. However, the patterns of factor/cross-factor loadings observed in the present study indicate that a "simple" structure was not attainable. Associations between factors and covariates attest to the discriminant validity of the factors, and the association between Emotional Numbing and functional impairment may afford clinicians an opportunity to better understand and target the most disruptive features of grief.

Predictors of Family Caregivers' Depressive- and Prolonged-Grief-Disorder-Symptom Trajectories

OBJECTIVE

Depression and prolonged grief disorder (PGD) are related but distinct constructs with different risk factors and treatments. We aimed to determine commonality and differences in factors predicting membership in depressive- and PGD-symptom trajectories to highlight uniqueness of each construct to guide further care and treatments.

METHODS

We previously identified four shared trajectories for depressive- and PGD-symptom trajectories (endurance, transient-reaction, resilience, and prolonged-symptomatic) with unique trajectories of chronically distressed and potential recurrence for depressive and PGD symptoms, respectively. This secondary-analysis study examined pre- and postloss factors predisposing 849 bereaved caregivers of cancer patients to membership in depressive- and PGD-symptom trajectories from the integrative framework of predictors for bereavement outcomes by a multinomial logistic regression model (the "endurance" trajectory as reference).

RESULTS

Common factors predicted membership in depressive- and PGD-symptom trajectories: higher postloss personal coping capacity protected from more distressing symptom trajectories, spousal relationship with the patient predicted membership in the transient-reaction trajectory, while financial hardship and preloss depressive symptoms predicted for the resilience trajectory. Yet, accurate prognostic awareness protected caregivers from more distressing depressive-symptom trajectories only. Higher preloss subjective caregiving burden protected caregivers from the four more distressing depressive-symptom trajectories but only from the transient-reaction and resilience trajectories for PGD symptoms.

CONCLUSION

Commonality and differences in factors predicting membership in PGD- and depressive-symptom trajectories confirm that PGD and depression are related but distinct constructs. Interventions should be tailored to caregivers' unique risk profile for depressive- and PGD-symptom trajectories to reduce the likelihood of suffering both or individual symptom trajectories.

Understanding Nepali widows' experiences for the adaptation of an instrument to assess Prolonged Grief Disorder

The experience of grief varies across different cultures and contexts. Women in Nepal who lose their husbands confront discrimination, social isolation, and abuse that influence their experience of grief. Through eight focus group discussions with Nepali widows, we elicited socially sanctioned grief reactions and local idioms used to describe common cognitive, behavioral, and emotional symptoms of grief. Accordingly, modifications to an existing instrument for Prolonged Grief Disorder, the PG-13, are suggested to capture grief symptoms as experienced by Nepali widows. Items in the PG-13 were translated to colloquial Nepali and adapted to maintain comprehensibility, acceptability, relevance, and completeness. Based on the grief-related issues reported in the focus group discussions, the addition of five new items and a new criterion to capture symptoms related to social discrimination are proposed. Widows perceived elevated symptoms one year after the loss to be problematic. It is thus recommended that the duration criterion in the original PG-13 be adjusted from at least six months to at least one year after the loss. These proposed modifications to the instrument should be validated through future psychometric testing.

French-Canadian validation of the Traumatic Grief Inventory-Self Report (TGI-SR)

The Traumatic Grief Inventory Self-Report (TGI-SR), which aims to assess both Persistent Complex Bereavement Disorder and Prolonged Grief Disorder, has been validated in several languages. This study sought to validate the French-Canadian version. We conducted an online survey exploring the impact of the COVID-19 pandemic on grief. With data from 728 participants, the scale demonstrated high internal consistency, correlated significantly with three other scales known to measure similar concepts, and distinguished between groups known to be different. This study supports the use of the TGI-SR French-Canadian version by clinicians and researchers to assess complications of grief.

Exploring the role of expectancy in older US participants' response to an accelerated resolution therapy intervention for prolonged grief disorder

Accelerated resolution therapy (ART) is a psychotherapy for the treatment of prolonged grief disorder (PGD) defined as severe, enduring longing for the lost person. Currently, ART lacks examination of intrapersonal processes, like expectancy, as behavioural mechanisms for action. Therefore, the purpose of this paper was to present the findings on participants' treatment expectations of ART for PGD and then discuss potential hypotheses for future testing. This study was a primary qualitative descriptive analysis of prospectively collected interview data (collected 2017-2019) accrued as part of a randomised, wait-list controlled clinical trial in bereaved hospice family caregivers in the United States. The sample included 29 former informal caregivers who were at least 1-year post death of their care recipient. They were primarily female, older (67.4 ± 7.1 years), and a little over half (n = 18) had been married to their care recipient. Thematic analysis resulted in three distinct themes with six sub-themes: The role of knowledge in expectations (sub-themes uncertainty, prior knowledge); The role of personality in expectations (sub-themes openness, positive affect); and Expecting a process (sub-themes cognitive processes, affective processes) which described the interaction of person and process in shaping expectations of our intervention. An across theme analysis of the specificity of the participants' expectations uncovered that knowledge and personality inform expectations of ART and that individuals who verbalise a process for recovery tend to be very specific in their expectations. Three hypotheses for testing are put forward and implications for practice, research and policy discussed.

Psychometric properties, stability, and predictive validity of the Korean version of the Prolonged Grief Disorder Scale (PG-13-K): A longitudinal study among bereaved Koreans

This study aims to investigate the psychometric properties, stability, and predictive validity of the PG-13-K. Two subsamples were used: the first subsample (N = 153), participated at Time 1 only, and the second subsample (N = 184) participated at both Time 1 and Time 2. At each time point, reliability, test-retest reliability, and validity were adequate, and the hypothesized two-factor model indicated good to excellent fit. Moreover, the PG-13-K was able to predict the correlation between prolonged grief disorder (PGD) and negative psychological factors. The PG-13-K is a useful and valid instrument for measuring PGD symptoms in Korean settings.
