Prevalence and risk factors of prolonged grief disorder among bereaved survivors seven years after the Wenchuan earthquake in China: A cross-sectional study

Psychometric Properties of the Revised Version of the Prolonged Grief Disorder Scale (PG-13-R): A Methodological Study in the Iranian Population

Prolonged grief disorder has recently been officially introduced as a new mental disorder. This study aimed to validate the Persian version of the revised Prolonged Grief Scale (PG-13-R). This study was conducted among the general population in Shahroud, Iran, during 2023. Employing face and content validity, along with exploratory and confirmatory factor analyses (EFA), the study validates the PG-13-R. Average variance extracted value showed an acceptable convergent validity. The EFA reveals a singular factor structure explaining 60.541% of the variance in prolonged grief disorder, and the confirmatory factor analysis demonstrates an excellent model fit. Internal consistency, evaluated through Cronbach's alpha and MacDonald's omega, highlights the scale's reliability. The Persian version of PG-13-R had acceptable composite reliability. Stability is confirmed by an intra-class correlation coefficient. In conclusion, the Persian PG-13-R displays satisfactory validity and reliability to assessing prolonged grief symptoms in the Iranian population.

The prevalence of prolonged grief disorder (PGD) after the natural disasters: A systematic review and meta-analysis

Objective

The failure to detect PDG and lack of providing essential interventions accordingly can disrupt the lives of survivors of natural disasters years after the death of their loved ones. The present study aims to investigate PGD after natural disasters using a systematic review and meta-analysis.

Study design

This study was performed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines.

Methods

With the focus on the prevalence of PGD after natural disasters, studies conducted until the end of 2021 were collected without a time limit. To do this, reputable databases such as PubMed, Web of Science, Scopus, Embase, Google Scholar, and Science Direct were used. The random effects model was used to perform a meta-analysis of the studies. To check the heterogeneity between the studies, the I2 index was used. The publication bias of the study was evaluated using Begg's test. Data were analyzed using the STATA software.

Results

Primarily, 2566 studies were collected based on the initial search, from which 12 final studies were entered into the analysis. The results showed that the prevalence of PGD after natural disasters was 38.81 % (95 % CI: 24.12-53.50, I2 = 99.7 %, p = 0 < 001).

Conclusions

It is recommended that policies and plannings of the organizations responsible for disaster management be prepared to send specialized teams of psycho-spiritual counseling, quickly accommodate the injured, and reconstruct the damaged buildings in the shortest time possible.

Bereavement issues and prolonged grief disorder: A global perspective

The death of a loved one - bereavement - is a universal experience that marks the human mental health condition. Grief - the cognitive, emotional, and behavioral responses to bereavement - is thus experienced by virtually everyone at some point in life, while mourning is a process through which grievers come to terms with the loss envisioning life without the deceased. Although distress subsides over time among most bereaved individuals, a minority will develop a condition recently identified as prolonged grief disorder (PGD). The present review provides a global perspective on bereavement, grief reactions, and PGD. Although the loss of a loved one and grief reactions are in general experienced consistently across different cultures, differences and variations in their expression may exist across cultures. Especially within specific populations that may be more at risk for PGD, possibly due to risk factors associated with the mechanisms of loss (e.g., refugees, migrants, and conflict survivors). The diagnostic criteria for PGD are mostly based on Western grieving populations, and cultural adaptations of PGD treatments are limited. Therefore, cross-cultural development and validation of PGD screening/assessment is critical to support future research on grief reactions and PGD, especially in non-Western contexts, and concerning the potential future global changes and challenges that appear to have a major impact on PGD. More transcultural research on PGD is needed to contextualize and will lead to culture-bound symptom identification of PGD, and the adaptation of current treatment protocols, which may ultimately improve health at the individual level, and health-care systems.

Disorganized attachment and prolonged grief

OBJECTIVE

While the relationship between attachment anxiety and avoidance and the severity of prolonged grief disorder (PGD) has been well-studied, less is known about the relationship between disorganized attachment and PGD. We test the associations between disorganized attachment and the interaction between it and attachment avoidance and anxiety on PGD.

METHOD

Participants (N = 258) who had lost a family member from 0.5 to 8.0 years before the survey completed the experiences in close relationships-revised, the adult disorganized attachment scale, and the PGD-13 scale.

RESULTS

The model explaining PGD symptoms through attachment, taking into account the level of disorganized attachment, explained variance in PGD significantly better than the model taking into account only the level of attachment anxiety and avoidance as predictors. Additionally, the relationships between attachment avoidance and PGD were positive, negative, or neither, depending on the configuration of the levels of disorganized attachment and attachment anxiety.

CONCLUSION

Future research into the relationships between attachment and PGD should take into account disorganized attachment. Attachment-informed grief therapy focused on insecure styles of attachment - including the disorganized style - to the deceased person and other loved ones may prove a promising approach for bereaved persons who experience PGD.

Prevalence of prolonged grief disorder

BACKGROUND

Prolonged grief is a disorder (PGD) characterized by severe and disabling grief reactions for an extended period of time after the loss of a significant person. ICD-11 and DSM-5-TR differ substantially in individual criteria.

OBJECTIVE

Estimation of the respective prevalence of PGD_ICD-11 and PGD_DSM-5-TR and the frequency with which single symptoms of prolonged grief occur in the general population.

METHODS

Out of a representative sample of the German general population (N=2498), n = 914 reported a significant loss and prolonged grief symptoms based on the extended version of the self-reported Prolonged Grief Disorder-13+9 (PG13+9). Sociodemographic and loss-related characteristics were collected.

RESULTS

The probable prevalence of PGD_ICD-11 was 1.5% and that of PGD_DSM-5-TR was 1.2% in the general sample. Among bereaved persons (n=914), the prevalence of developing PGD_ICD-11 was 4.2% and that of PGD_DSM-5-TR was 3.3%. Diagnostic agreement between the two criteria-sets was very high and did not increase after heightening the accessory symptom threshold for PGD_ICD-11. Difficulties accepting the loss was the most frequent single symptom (14-25%) and grief-related impairment was common (10-16%). Over 60% of participants with a probable PGD diagnosis utilized health care services.

LIMITATIONS

Results are based on self-reported data. The PG13+9 was not designed to assess grief symptoms according to ICD-11 and DSM-5-TR diagnostic criteria.

CONCLUSIONS

Prolonged grief according to ICD-11 and DSM-5-TR is a notable disorder in the general population. Among bereaved persons, single symptoms of prolonged grief are relatively frequent and cause substantial degrees of impairment.

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.

Who suffered most after deaths due to COVID-19? Prevalence and correlates of prolonged grief disorder in COVID-19 related bereaved adults

BACKGROUND

Deaths by COVID-19 have left behind nearly 12 million recent bereaved individuals worldwide and researchers have raised concerns that the circumstances of COVID-19 related deaths will lead to a rise prevalence of prolonged grief disorder (PGD) cases. However, to date, no studies have examined the prevalence of PGD among people bereaved due to COVID-19. This study aimed to estimate the prevalence of PGD and investigated demographic and loss-related factors associated with prolonged grief symptoms among Chinese individuals bereaved due to COVID-19.

METHODS

This was a cross-sectional online survey conducted between September 1 and October 3, 2020. A total of 422 Chinese participants (55.5% males; 32.73 [9.31] years old) who lost a close person due to COVID-19 participated in the study. Demographic and loss-related information was collected, and self-reported prolonged grief symptoms were measured by a 13-item International Prolonged Grief Disorder Scale (IPGDS: 1-65) and a 17-item Traumatic Grief Inventory Self Report (TGI-SR: 1-85). Multiple linear regression analysis was used to determine the associated factors of levels of grief symptoms.

RESULTS

Prevalence of PGD was 37.8% screened by IPGDS and 29.3% by TGI-SR. No difference was found in levels of grief symptoms between participants whose close one died more than 6 months ago and those who experienced the loss less than 6 months ago. More severe prolonged grief symptoms assessed by IPGDS was associated with losing a close person by COVID-19 rather than complications (B: 5.35; 95% CI: 0.54-10.05), losing a partner (B: 7.80; 95% CI: 3.24-12.37), child (B: 8.15; 95% CI: 1.03-15.26), and parent (B: 5.49; 95% CI: 1.49-9.48) rather than losing a relative or a person with other relationship, feeling more traumatic about the loss (B: 1.71; 95% CI: 0.52-2.90), being closer with the deceased (B: 1.60; 95% CI: 0.34-2.86). Moreover, Losing a grandparent (B: 6.62; 95% CI: 0.53-12.71) and having more conflicts with the deceased (B: 1.05; 95% CI: - 0.008-2.11) were related to higher levels of grief symptoms assessed by TGI-SR.

CONCLUSIONS

Echoing researchers' concerns, the prevalence of PGD is high among people bereaved due to COVID-19. Individuals with a higher risk of developing PGD should be identified and bereavement support should be offered as early as possible.

Loss and grief in elderly people: Results from the LIFE-Adult-Study

We evaluated 2,865 elderly people to investigate the prevalence of prolonged grief disorder (PGD), examine predictors and mental health correlates. The conditional prevalence of PGD varied between 0.8% and 5.2% (diagnostic algorithm vs. cut-off). PG-13 scores were related to depressive symptoms, sleep disturbances, reduced life satisfaction, and quality of life. Predictors were female gender, less time since death, more losses, having lost a child, partner, or sibling, and less social support. PGD is associated with adverse mental health consequences. Practitioners should pay special attention to elderly women who lost a close loved one and lack social support.

Prolonged grief disorder in Chinese Shidu parents who have lost their only child

Background: China has the largest population of '"loss-of-only-child' parents, that are also known as Shidu parents in Chinese society; however, little is known about their unresolved grief. Objective: This is the first study to examine the grief symptoms, prevalence, comorbidity and potential predictors of prolonged grief disorder (PGD) in such parents, taking into consideration that the new PGD diagnostic criteria ICD-11 will soon be implemented in China. Methods: 149 Shidu parents completed assessments of PGD (PG-13), PTSD (PCL-C), depression (CES-D) and general psychiatric morbidity (GHQ-12) via in-person interviews. Results: Of the 149 Shidu parents, 22.2% met the PGD criteria, with a mean of 7.59 years post-loss, and 62.4% experienced daily longing or yearning. Regression analysis indicated that fewer years since loss, subjective perception of poor economic situation, female gender and more hospital visits were prominent risk factors for the development of PGD. Older age of the parents at the time of child loss was also associated with PGD. Parents with PGD had higher comorbidity of PTSD or depression compared with those without PGD. Conclusions: There is a high prevalence of PGD and a high rate of comorbidity between PGD and PTSD or depression in Shidu parents in China, which highlights the need of timely developing effective assessments and interventions to prevent PGD in this population, particularly in female, recently bereaved, low-income and aged parents who lost their only child.

Prolonged Grief Disorder and the Cultural Crisis

Prolonged grief disorder (PGD) is included as a new mental health disorder in the 11th edition of the International Classification of Diseases (ICD-11). Understandably, this has boosted research efforts to investigate this newcomer to psychopathology. However, the use of different diagnostic algorithms has resulted in substantially different prevalence rates both within and across cultural groups. Furthermore, global applicability of the new criteria outside of the Global North has not been yet been established. This perspective presents key findings from Asian research groups and discusses the roadblocks to unified PGD research, including the heterogeneric use of diagnostic algorithms and the lack of cultural compatibility of ICD-11 items. The authors discuss the key issues and address implications for practice.

The prevalence of complicated grief among Chinese people at high risk: A systematic review and meta-analysis

OBJECTIVE

This unprecedented systematic review aims to unearth the rate of CG among Chinese people.

METHODS

Data sources were from PsycINFO, ProQuest Databases, Web of Science, PsycARTICLES, China National Knowledge Infrastructure (CNKI), WanFang, Taiwan Periodical Literature System (TPLS), HKInChiP from the inception to June 2019. The eligibility criteria for inclusion were (a) including or useful to calculate the prevalence of CG in Chinese settings, (b) published in journals, (c) containing information on sample size, (d) full texts either written in English or in Chinese are available. Thirteen studies were engaged in meta-analytic evaluation after the systematic review. They were appraised by the risk of bias (RoB) for publication-quality and synthesized through meta-analysis for identifying the prevalence of CG among Chinese people.

RESULTS

Meta-analysis revealed a pooled estimate of CG of 22.0% (95% CI: 0.111-0.391). The studies identified in this review were of methodological heterogeneousness and focused on the population at high risk of CG. They were a moderate or high risk of bias.

CONCLUSION

Results warrant the need to conduct a population-based and quality study to investigate the prevalence of CG in Chinese people. Many suggestions on treatment for Chines people with CG were provided.
