Predictors of Prolonged Grief Disorder in a German Representative Population Sample: Unexpectedness of Bereavement Contributes to Grief Severity and Prolonged Grief Disorder

Experiences of Iranian people who lost a partner in road traffic collisions: A descriptive phenomenology

This study explores the experiences of Iranian bereaved spouses who lost partners in Road Traffic Collisions (RTCs) one to three years earlier. Seventeen participants were interviewed using purposive sampling. Three central themes emerged: (1) "The unfillable void," revealing the profound emptiness experienced by the bereaved, the factors that maintain this void, and the challenges in accepting human-induced deaths as fate. This leads to difficulties in finding meaning in the loss, resulting in anger and seeking revenge; (2) "The Iranian mourning," exploring cultural impacts such as Chehelom, alongside confronting loneliness that ensues after this period ends, and the cultural stigma faced by the bereaved; (3) "One's perspective on life," highlighting personal growth amid adversity. The study emphasizes the necessity for culturally sensitive support services and suggests psychological therapies addressing feelings of retaliation and fury. These insights offer valuable contributions to understanding bereavement in diverse cultural contexts, informing legislators and healthcare professionals.

The Norwegian traumatic grief inventory-self report plus (TGI-SR+): a psychometric evaluation in traumatically bereaved people

Background: Prolonged grief disorder (PGD) has been added to the ICD-11 and DSM-5-TR. The Traumatic Grief Inventory-Self Report Plus (TGI-SR+) assesses self-rated PGD intensity as defined in ICD-11 and DSM-5-TR. The TGI-SR + is available in multiple languages, but has not been validated yet in Norwegian.Objective: The aim of this study was to evaluate the psychometric properties of the Norwegian TGI-SR + .Method: Bereaved adults (N = 307) whose child or sibling died ≥6 months ago due to a sudden or violent loss completed the TGI-SR + and measures for posttraumatic stress, depression, and precursor PGD symptoms. We examined the factor structure and internal consistency of the ICD-11 and DSM-5-TR PGD items. Convergent validity and known-groups validity was evaluated. Probable PGD cases, pair-wise agreement between diagnostic scoring rules for both PGD criteria-sets, and cut-off scores were calculated.Results: The 1-factor model for ICD-11 and DSM-5-TR PGD showed the best fit and demonstrated good internal consistency. Convergent validity was supported by strong associations between summed ICD-11 and DSM-5-TR PGD scores and summed posttraumatic stress, depression, and precursor prolonged grief scores. Known-groups validity was supported by PGD intensity being related to educational level and time since loss. The perfect pair-wise agreement was reached using the ICD-11 and DSM-5-TR PGD diagnostic scoring rules. The optimal cut-off score for detecting probable PGD cases, when summing all TGI-SR + items, was ≥73.Conclusions: The Norwegian TGI-SR + seems a valid and reliable instrument to assess ICD-11 and DSM-5-TR PGD intensity after losing a child or sibling under traumatic circumstances.

The mental health of Australians bereaved during the first two years of the COVID-19 pandemic: a latent class analysis

BACKGROUND

The COVID-19 pandemic disrupted many areas of life, including culturally accepted practices at end-of-life care, funeral rites, and access to social, community, and professional support. This survey investigated the mental health outcomes of Australians bereaved during this time to determine how these factors might have impacted bereavement outcomes.

METHODS

An online survey indexing pandemic and bereavement experiences, levels of grief, depression, anxiety, and health, work, and social impairment. Latent class analysis (LCA) was used to identify groups of individuals who shared similar symptom patterns. Multinomial regressions identified pandemic-related, loss-related, and sociodemographic correlates of class membership.

RESULTS

1911 Australian adults completed the survey. The LCA identified four classes: low symptoms (46.8%), grief (17.3%), depression/anxiety (17.7%), and grief/depression/anxiety (18.2%). The latter group reported the highest levels of health, work, and social impairment. The death of a child or partner and an inability to care for the deceased due to COVID-19 public health measures were correlated with grief symptoms (with or without depression and anxiety). Preparedness for the person's death and levels of pandemic-related loneliness and social isolation differentiated all four classes. Unemployment was associated with depression/anxiety (with or without grief).

CONCLUSIONS

COVID-19 had profound impacts for the way we lived and died, with effects that are likely to ricochet through society into the foreseeable future. These lessons learned must inform policymakers and healthcare professionals to improve bereavement care and ensure preparedness during and following future predicted pandemics to prevent negative impacts.

Prevalence and correlates of ICD-11 prolonged grief disorder among adults living in Ukraine during the war with Russia

BACKGROUND

Although high rates of bereavement are evident in war-affected populations, no study has investigated the prevalence and correlates of probable ICD-11 prolonged grief disorder (PGD) under these circumstances.

METHODS

Participants were 2050 adults who participated in a nationwide survey exploring the effects of the Ukraine-Russia war on the daily lives and mental health of Ukrainian people.

RESULTS

Of the total sample, 87.7% (n = 1797) of people indicated a lifetime bereavement. In the full sample, 11.4% met the diagnostic requirements for probable ICD-11 PGD, and amongst those with a lifetime bereavement, the conditional rate of probable ICD-11 PGD was 13.0%. Significant risk factors of ICD-11 PGD included the recent loss of a loved one (6 months to a year ago), being most affected by a partner or spouse's death, loved one dying in the war, no recent contact with the deceased prior to their death, and meeting depression and anxiety diagnostic requirements.

CONCLUSION

The study reveals that a significant percentage of Ukrainian bereaved individuals have probable ICD-11 PGD, and identifying risk factors, particularly war-related losses, will aid in the development of intervention and prevention programs for bereaved adults.

Prolonged grief in relatives of deceased patients due to COVID-19 is associated with anxiety and depressive symptoms: A survey-based study in Peru

Objective

Funeral practices have undergone significant changes during the COVID-19 pandemic. Thus, the death of a family member from this disease has altered the typical course of the bereavement process. Therefore, this study seeks to determine the relationship between the levels of grief, anxiety, and depression in relatives of patients who died from COVID-19 in Peru.

Methods

A total of 250 volunteers were obtained, but after applying the inclusion criteria and not being able to contact five of them, the sample consisted of 115 participants over 18 years of age who lost a family member to COVID-19 between 2020 and 2021. They developed the Prolonged Grief Questionnaire-13 and the Zung Anxiety and Depression Questionnaires, in virtual surveys using Google FormTM (Google, CA).

Results

Our analysis revealed that all cases of anxiety (18.3%) were present in individuals experiencing prolonged grief (76.5%), while 49.5% (57/115) of participants exhibited symptoms of depression. Furthermore, we identified a significant association between prolonged grief and both anxiety (p = 0.005) and depression (p < 0.001). Prolonged grief predominantly affected females (45.2%) and individuals aged 31-40 years (28.7%) (p < 0.001). Regarding predictors of anxiety symptoms, we found that both age group (p = 0.035) and grief (p < 0.001) played significant roles. Gender (p = 0.019) and grief (p < 0.001) emerged as predictors of depression, while gender alone predicted grief in relatives of individuals who succumbed to COVID-19 (p = 0.019).

Conclusion

Our results suggest a clear association between prolonged grief and mental health issues among relatives of COVID-19 patients who have passed away. Consequently, it is imperative to provide comprehensive psychological and spiritual support throughout the grieving process, aiming to mitigate the negative impact of traumatic events.

The study of psychosocial outcomes of parents bereaved by pediatric illness: a scoping review of methodology and sample composition

OBJECTIVE

Parents of children who died of a medical condition experience a range of psychosocial outcomes. The current scoping review aims to summarize the outcomes assessed, methodology, and sample characteristics of recent psychosocial research conducted with this population.

METHODS

Included studies were limited to peer-reviewed, psychosocial outcomes research published between August 2011 and August 2022, written in English, and including caregiver study participants of children who died of a medical condition. Data sources were scholarly journal articles from 9 electronic databases, including Scopus, Web of Science, Academic Search Primer, ProQuest Research Library, PubMed, Embase, PsycINFO, Psychology & Behavioral Sciences Collection, and Health Source: Nursing/Academic Edition. The Mixed Methods Appraisal Tool-2018 evaluated methodological quality.

RESULTS

The study sample included 106 studies, most of which were either qualitative (60%) or quantitative (29%). Mixed-methods studies (8%) and randomized clinical trials (2%) were also identified. Study quality was variable, but most studies met all quality criteria (73%). Studies primarily represented cancer populations (58%), White participants (71%), and mothers (66%). Risk-based psychosocial outcomes (e.g., grief) were more commonly assessed than resilience-based outcomes.

CONCLUSIONS

The current scoping review revealed that recent research assessing the psychosocial outcomes of bereaved parents is limited in the representation of diverse populations, primarily qualitative, of broadly strong methodological quality, and oriented to psychosocial risk. To enhance the state of the science and inform evidence-based psychosocial services, future research should consider varied methodologies to comprehensively assess processes of risk and resilience with demographically and medically diverse populations.

Prevalence of prolonged grief disorder and its symptoms among bereaved individuals in China: a systematic review and meta-analysis

Background

The prevalence of prolonged grief disorder (PGD) and its symptoms among the bereaved population in China vary considerably.

Aims

This meta-analysis aims to estimate the prevalence of PGD and its symptoms among bereaved individuals in China.

Methods

We conducted a literature search in major Chinese and English databases from their inception to 4 October 2023, for cross-sectional studies on the prevalence of PGD or its symptoms in bereaved Chinese individuals. The risk of bias of the included studies and certainty of the evidence were assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data ('JBI checklist') and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE), respectively. The 'metaprop' package in R V.4.1.2 was used to synthesise the prevalence.

Results

A total of 28 studies involving 10 994 bereaved individuals were included in the analysis, with JBI checklist scores between 3 and 7. The combined prevalence (95% confidence interval) of PGD and its symptoms was 8.9% (4.2% to 17.6%) and 32.4% (18.2% to 50.8%), respectively. PGD and its symptoms were most prevalent among those who had lost their only child (22.7%) and those bereaved by earthquakes (80.4%), respectively. The GRADE system assigned a very low certainty level to the evidence for the pooled prevalence of PGD and its symptoms.

Conclusions

The pooled prevalence of PGD and its symptoms indicate a potential high need for grief counselling services among bereaved individuals in China. This need is particularly pronounced in those who have lost their only child and those bereaved due to earthquakes. Further methodologically rigorous studies are needed to provide more accurate prevalence estimates.

Latent trajectories of DSM-5-TR-based Prolonged Grief Disorder: findings from a data pooling project MARBLES

Background: With the release of the text revision of the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5-TR), criteria for Prolonged Grief Disorder (PGD) were included. This necessitates studying grief trajectories based on these criteria.Objective: This is the first study examining latent trajectories of DSM-5-TR-based PGD symptom levels and testing whether specific risk factors (e.g. cause of death) predicted PGD trajectories.Method: We evaluated latent DSM-5-TR PGD trajectories using pooled existing data collected at 6-12, 13-24, and 25-60 months post-loss in Danish and Dutch bereaved adults (N = 398). Latent Growth Mixture Modelling (LGMM) was employed to determine the trajectories. Multinomial logistic regression analyses were used to examine which risk factors predicted class membership.Results: The four-class LGMM solution with a quadratic term was best-fitting the data. This solution represented four trajectories: High stable PGD (6%), High PGD quick recovery (10%), High PGD slow recovery (35%), and Low PGD symptoms (49%). Participants with a higher educational level were more likely to be assigned to the Low PGD symptoms trajectory compared to High stable PGD and High PGD slow recovery trajectories. Unnatural causes of death increased the likelihood of being in the High stable PGD and High PGD slow recovery trajectories compared to the Low PGD symptoms trajectory.Conclusions: Consistent with prior research, the Low PGD symptoms trajectory was the most common. A significant minority experienced high and stable levels of PGD within five years after the loss. About one-third of participants experienced high acute grief levels that decreased slowly; how slow decreasing symptoms relate to an individual's functioning requires further attention. This study demonstrates that a significant minority of bereaved people develop acute PGD symptomatology that does not diminish within five years post-loss, emphasizing the need for early screening for PGD to prevent long-lasting complaints.

Psychometric evaluation of the Swedish Traumatic Grief Inventory Self-Report Plus (TGI-SR+) in bereaved parents

The International Classification of Diseases Eleventh Edition (ICD-11), and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR), now include prolonged grief disorder (PGD). Since criteria for PGD in both classification systems differ from prior proposed grief disorders and each other, the validation of a single instrument to screen for prolonged grief (PG) symptoms of both new diagnoses is critical for bereavement research and care. Therefore, we evaluated the psychometric properties of the Swedish version of the Traumatic Grief Inventory Self-Report Plus (TGI-SR+). Two-hundred and forty-eight bereaved parents completed questions about sociodemographic and loss-related variables, the TGI-SR+, and symptom measures of post-traumatic stress (PTS), depression and an older measure of PG symptoms, the Prolonged Grief Disorder-13 (PG-13). Confirmatory factor analyses showed that a one-factor model best fit DSM-5-TR and ICD-11 PG symptoms and the analyses of the internal consistency and inter-item correlations showed that these symptoms could be reliably assessed. In support of convergent validity, DSM-5-TR and ICD-11 PG symptoms correlated with symptoms of PTS, depression and PG assessed with the PG-13. In support of known-groups validity, DSM-5-TR and ICD-11 PG symptoms were higher among lower educated (vs. higher educated) participants and related negatively to time since loss. ROC analyses showed optimal cut-off score of ≥71 and ≥72 to determine probable caseness for DSM-5-TR and ICD-11 PGD, respectively. Results support the reliability and validity of the Swedish TGI-SR+ as a screening instrument for PG in research and bereavement care.

Prevalence of Prolonged Grief Disorder and Related Clinical Factors Among Turkish Psychiatric Outpatients During the COVID-19 Pandemic

Prolonged grief disorder (PGD), a new diagnosis in some classification systems, has gained prominence due to the high mortality rates observed during the Covid-19 pandemic. Herein, the prevalence of PGD (diagnosed with structured clinical interviews), death-related features, and associated clinical factors were investigated among outpatient psychiatric patients who lost a first-degree relative within the past 12-24 months. PGD was diagnosed in 30/68 patients (44.1%). PGD development did not differ based on cause of death (Covid-19-related vs. other causes) but was associated with higher age of the bereaved, younger age of the deceased, and degree of kinship. Higher rates of depression, insomnia, and anxious attachment were also observed in PGD patients. Finally, the unexpectedness of death predicted the development of PGD. Due to the high prevalence of PGD among psychiatric patients, clinicians should be aware of the disorder, monitor grief processes in high-risk patients, and consider PGD in treatment planning.

Prevalence, Factor Structure and Correlates of DSM-5-TR Criteria for Prolonged Grief Disorder

BACKGROUND

Prolonged Grief Disorder (PGD) is now included in Section II of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, Text Revision (DSM-5-TR). To understand the health burden and then allocate economic and professional resources, it is necessary to provide epidemiological data for this new disorder. This is especially relevant since the new diagnostic criteria differ from its predecessors, which may affect the generalizability of previous findings. More information on the characteristics of people suffering from PGD is also beneficial to better identify individuals at risk. This study, therefore, aimed to estimate the prevalence of the new PGD criteria in a representative population-based sample, evaluate the factor structure, sociodemographic, and loss-related correlates of PGD caseness and explore possible predictors.

METHODS

Out of a representative sample of the German general population (N = 2,531), n = 1,371 (54.2%) reported to have experienced a significant loss throughout lifetime. Participants provided sociodemographic data and loss-related characteristics. PGD symptoms were measured using items from the German versions of the Prolonged Grief Scale (PG-13) and the Inventory of Complicated Grief (ICG), which could be matched to the DSM-5-TR criteria for PGD.

RESULTS

The conditional prevalence of PGD was 3.4% (n = 47). The most frequently reported symptoms were intense emotional pain and intense yearning or longing for the deceased. The confirmatory factor analysis confirmed a unidimensional model of PGD. Regression analysis demonstrated that time since the death, the relationship to the deceased, and unpreparedness for the death were significant predictors of PGD.

CONCLUSION

Although the prevalence of 3.4% using the new diagnostic criteria is lower than the prevalence previously suggested by a meta-analysis, PGD remains a substantial disorder in the general population. In particular, the loss of a partner or child increases the risk for PGD, as does unpreparedness for the death of a loved one. Clinicians should pay particular attention to these high-risk groups. Further clinical implications are discussed.

A Latent Class Analysis on Symptoms of Prolonged Grief, Post-Traumatic Stress, and Depression Following the Loss of a Loved One

BACKGROUND

The loss of a significant other can lead to variety of responses, including prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), and depression. The aim of this study was to replicate and extend previous research that indicated that three subgroups of bereaved individuals can be distinguished based one similar post-loss symptom profiles using latent class analysis (LCA). The second aim was to examine whether sociodemographic and loss-related characteristics as well as the extent of meaning making were related to classes with more pervasive psychopathology.

METHODS

Telephone-based interviews with 433 Dutch and German speaking persons who had lost a significant other at last 6 months earlier were conducted. Self-rated PGD, PTSD, and depression symptoms were assessed. LCA was conducted and correlates of class-membership were examined using the 3step approach.

RESULTS

The LCA resulted in three distinct classes: a no symptoms class (47%), a moderate PGD, low depression/PTSD class (32%), and a high PGD, moderate depression/PTSD class (21%). A multivariate analysis indicated that female gender, a shorter time since loss, an unexpected loss and less meaning made to a loss were significantly associated with membership to the moderate PGD, low depression/PTSD and high PGD, moderate depression/PTSD class compared to membership to the no symptom class. Losing a child or spouse, a shorter time since loss, and having made less meaning to the loss further distinguished between the high PGD, moderate depression/PTSD symptom class and the moderate PGD, low depression/PTSD class.

DISCUSSION

We found that the majority of individuals coped well in response to their loss since the no symptom class was the largest class. Post-loss symptoms could be categorized into classes marked by different intensity of symptoms, rather than qualitatively different symptom patterns. The findings indicate that perceiving the loss as more unexpected, finding less meaning in the loss, and loss-related factors, such as the recentness of a loss and the loss of a partner or child, were related to class membership more consistently than sociodemographic factors.
