Background: Prolonged Grief Disorder (PGD) has recently been included in both the ICD-11 and DSM-5-TR diagnostic manuals. Studying its prevalence and correlates across cultures is vital for more effective identification, treatment, and prevention.Objective: This study aimed to examine prevalence rates of ICD-11-based PGD, in a representative Slovakian sample in response to deaths of loved ones occurring during the previous year. Further aims were to examine the factor structure of PGD symptoms and correlates of summed PGD item scores and PGD \'caseness\'.Method: Self-reported data on PGD, depression, anxiety, alcohol use, and descriptive characteristics were gathered from a representative sample of the Slovak population (N = 319).Results: Data were gathered from N = 1853 people; 319 participants (17.2%) reported a loss in the past year. The prevalence of probable PGD among these bereaved participants was 1.99% for recent losses (<6 months, n = 151) and 7.75% for more distant losses (6-12 months, n = 130). The most frequently endorsed symptoms included longing/yearning for the deceased, sadness, denial/unrealness, and difficulty accepting the death. PGD symptoms had a unitary factor structure which was consistent for subsamples bereaved 1-5 and 6-12 months. The severity of PGD varied with kinship. Depression and anxiety, but not alcohol misuse, were associated with PGD severity and PGD caseness.Conclusions: These findings underscore that a significant group of people develop PGD between 6-12 months following a loss. This emphasises the need for targeted psychological interventions.
Prolonged Grief Disorder (PGD) is newly included in ICD-11 and knowledge about its prevalence and correlates in the general population is urgently needed.In a representative Slovakian sample (N = 1853), 319 people (17.2%) reported a loss during the past year; 7.75% of people, bereaved 6–12 months earlier, met criteria for ICD-11-based PGD.PGD severity and caseness were associated with kinship (but less strongly with other sociodemographic and loss characteristics) and with depression and anxiety (but less strongly with problematic alcohol use).At 6–12 months following loss, PGD seems fairly common in the general population and timely identification and mitigation of PGD is an important public health issue.

UNASSIGNED: Mobile apps provide a unique platform for mental health assessment and monitoring. They can provide real time, accessible data on symptoms of mental disorders that may yield rich data for detailed clinical assessment and help individuals gain insight into their current mental state. We developed one of the first apps for tracking symptoms of prolonged grief disorder.
UNASSIGNED: In this pilot feasibility study, we assess the feasibility and acceptability of a new mobile app mGAGE for use once a day for 3 weeks. 27 participants completed mental health assessments at t1 and t2.
UNASSIGNED: Adherence to the app protocol was very high with 100% for the first two weeks of use. A surprising finding was the improvement of grief symptoms at t2. Debriefing interviews revealed general qualitative categories including positive feedback, negative feedback and specific recommendations. Overall, the app was found to be feasible for use for the first two weeks and acceptable for bereaved individuals.
UNASSIGNED: This app could provide valuable data for in depth clinical assessment, may support individuals to gain greater insight into their symptoms and may have a therapeutic effect in terms of improved grief symptoms. Implications for future studies including use in larger intervention studies are discussed.

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.

Background: Refugees and asylum seekers (ASRs) are frequently exposed to loss in addition to a variety of other stressors and often display high levels of various psychological symptoms.Objective: The study aimed to primarily determine clusters of prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), and depression symptoms in bereaved ASRs and secondly identify predictors of cluster membership. Sociodemographic  - and flight-related variables were investigated in exploratory analyses.Method: ASRs in Germany (N = 92) with interpersonal loss exposure, i.e. at least one missing or deceased relative or friend, were assessed with interview-based questionnaires for PGD, PTSD, and depressive symptoms. We used k-means cluster analysis to distinguish symptom profiles and logistic regression analyses to identify predictors of cluster membership.Results: We found a three-cluster-solution. The PGD-cluster (30%) was characterised predominantly by PGD symptoms, while the PGD/PTSD-cluster (32%) had high PGD and PTSD and moderate depressive symptoms. The resilient cluster (38%) showed low symptoms overall. insecure residence status predicted membership in the PGD and PGD/PTSD clusters relative to the resilient cluster, whilst higher attachment anxiety predicted membership in the PGD/PTSD cluster relative to the other clusters. Explorative analysis revealed duration of stay as a significant predictor.Conclusion: Findings can extend the current knowledge about different symptom profiles among bereaved ASRs in Europe. Insights to attachment  - and migration-related variables distinguishing between these profiles offer starting points for interventions.
Bereaved asylum seekers and refugees in Germany can be grouped into three symptom clusters: (1) predominantly prolonged grief, (2) high prolonged grief, high posttraumatic stress, and moderate depressive symptoms, and (3) low symptom load.Attachment  – and migration-related variables (i.e. residence status, duration of stay, and attachment anxiety) distinguish between cluster membership.Results highlight the importance of attending to profiles and not only single categories of symptoms and attachment features in bereaved asylum seekers and refugees.

Research indicates that post-bereavement coping strategies can be adaptive or maladaptive. Understanding which strategies lead to poorer outcomes is an important clinical and theoretical question with the potential to guide intervention. The Oxford Grief - Coping Strategies scale was developed from interviews with bereaved people with and without prolonged grief disorder (PGD) to assess the frequency of maladaptive cognitive and behavioural strategies after bereavement. Factorial and psychometric validity were assessed using exploratory and confirmatory factor analysis (N = 676). A three-wave cross-lagged panel model (N = 275) was used to assess the predictive validity of the tool in explaining symptoms of PGD. Results supported a four-factor solution (Avoidance, Proximity Seeking, Loss Rumination, Injustice Rumination) with good psychometric properties. The OG-CS predicted prospective symptoms of PGD in the short-term (6-12 months) and long term (12-18 months), controlling for baseline symptoms and autocorrelations. Subscale analyses demonstrated that the use of coping strategies predicted ICD-11 PGD in both the short-term and the long-term. However, avoidance was not predictive of outcomes early in the grieving process. At 6-12 months, avoidance predicted PGD at 12-18 months.

BACKGROUND: This study sought to test the distinctiveness of symptoms of prolonged grief disorder (PGD) from posttraumatic stress disorder (PTSD) and depression.
METHODS: Confirmatory factor analysis (CFA) and target exploratory factor analysis (EFA), were used to test the distinctiveness of PGD from PTSD and depression symptoms in a large sample of adults bereaved for at least six months (N = 1917). Identified factors were explored in relation to demographic (i.e., age, gender) and loss-related (i.e., time since bereavement, nature of death, relationship to deceased, age of deceased, and frequency of contact with deceased) correlates.
RESULTS: The CFA model provided a good fit to the data, while the target EFA provided a slightly improved fit. All items loading strongly and significantly onto their respectively factors, and the IGQ items had few significant cross-factor loadings. All demographic and loss-related variables (except for death of a sibling and death from other causes) were associated with each of the factors, however, these associations were strongest for the PGD factor.
CONCLUSIONS: Participants were recruited using a non-probability sampling method and were from a relatively affluent Western nation.
CONCLUSIONS: Findings from the current study demonstrate that PGD reflects an empirically distinguishable albeit related disorder to PTSD and depression in a sample of bereaved adults. The identification of correlates common to PGD, PTSD, and depression, as well as those unique to PGD, affords a comprehensive understanding of the risk factors associated with bereavement-related psychopathology.

Prolonged Grief Disorder (PGD) was recently added to ICD-11 and DSM-5-TR. Depression and Posttraumatic Stress Disorder (PTSD) are frequent comorbidities, but findings regarding comorbid somatoform disorder and personality disorders remain mixed and studies with severely impaired patients are scarce. It was therefore the objective of the present study to examine comorbidities of PGD in a bereaved inpatient psychiatric sample. We assessed N = 101 bereaved inpatients in a psychiatric hospital with clinical interviews and self-report questionnaires. We calculated differences between patients with and without a PGD-diagnosis in number and type of comorbid disorders as well as associations between the severity of PGD and comorbid disorders. On average, patients had 2.53 comorbid psychiatric diagnoses. Patients with and without a PGD-diagnosis did not differ in their number of comorbid diagnoses, and there was no association between number of comorbid diagnoses and PGD-severity. However, patients with PGD, had significantly more comorbid diagnoses belonging to neurotic-, stress-related and somatoform disorders of the ICD-10. Patients with PGDICD-11 also had significantly higher scores in self-reported depressive, PTSD-, and somatoform symptoms, as well as the negative affectivity personality domain than those without a PGD diagnosis. To the best of our knowledge, this is the first study to provide insights into comorbidities of PGD in a bereaved inpatient psychiatric sample. It highlights the importance of considering PGD symptoms as part of the complaints of bereaved patients to achieve a tailored treatment approach. Future longitudinal studies are needed to unveil relationships between pre-existing mental disorders and PGD.

OBJECTIVE: This study sought to determine whether the symptoms of prolonged grief disorder (PGD) according to ICD-11 and DSM-5-TR have a unifactorial structure. Second, we sought to determine the sociodemographic and loss-related correlates of PGD symptom severity according to ICD-11 and DSM-5-TR.
METHODS: People who had lost a spouse (N = 144) in the past six months were examined using the Polish versions of the Prolonged Grief Disorder-13 scale (PG-13) and Inventory of Complicated Grief (ICG). Selected PG-13 and ICG items were included in the analyses to cover the PGD criteria according to ICD-11 and DSM-5-TR.
RESULTS: Confirmatory factor analyses supported the one-dimensional structure of both sets of symptoms of the disorder. Briefer time since loss and loss due to an accident were associated with PGD symptom severity according to both ICD-11 and DSM-5-TR.
CONCLUSIONS: PGD is a one-dimensional and internally consistent psychopathological syndrome. Widows and widowers who have recently lost their spouse due to an accident may be at especially heightened risk of developing severe levels of PGD symptoms.

BACKGROUND: Prolonged grief disorder (PGD), a condition characterized by severe, persistent, and disabling grief, is newly included in ICD-11 and DSM-5-TR. Psychotherapies are among the most recommended treatments for PGD, but which should be considered as first-line treatment needs to be clarified. The purpose of this systematic review and network meta-analysis was to synthesize the available evidence to compare five outcomes of different psychotherapies on PGD in adults and identify the optimal psychotherapy modality to inform clinical decision-making for the treatment of PGD.
METHODS: A comprehensive search was conducted in 7 databases from inception until March 20th, 2023. In the frequentist framework, pairwise and network meta-analyses using random-effects models were performed for outcomes with 95 % confidence interval (CI).
RESULTS: There were 2962 records found and 55 studies (1,0330 participants) assessing 11 different psychological interventions were included. Compared with the waiting list, behavioral therapy (SMD=-1.05; 95 %CI=-1.71, -0.38), third-wave cognitive behavior therapy (SMD=-1.00; 95 %CI =-1.41, -0.58), family therapy (SMD=-0.87; 95 %CI=-1.59, -0.16), psychodynamic therapy (SMD=-0.88; 95 %CI=-1.67, -0.10) and cognitive therapy (SMD=-0.84; 95 %CI=-1.57, -0.12) were statistically effective in reducing grief symptom. Only cognitive behavior therapy (OR =0.48; 95 %CI = 0.27, 0.85) was more acceptable than waiting list. In terms of secondary outcome, third-wave CBT can statistically significantly reduce depression (SMD= -0.60; 95 %CI =- 0.84, -0.36), PTSD (SMD=-0.99; 95 %CI =- 1.62, -0.36) and anxiety (SMD= -1.44; 95 %CI =-2.63, -0.25) respectively.
CONCLUSIONS: Most psychological interventions are effective, but only cognitive behavior therapy has the highest acceptability. Third-wave CBT with higher efficacy rates may be more beneficial for reducing secondary outcomes. To provide more robust evidence, high-quality trials should be conducted in the future.

The International Grief Questionnaire (IGQ) is a self-report measure of ICD-11 Prolonged Grief Disorder (PGD) in adults. This study sought to develop and validate a caregiver-report version of the IGQ for children and adolescents aged 7-17 years; the IGQ-Caregiver Version (IGQ-CG). 639 parents living in Ukraine provided data on themselves and one child in their household as part of the \"The Mental Health of Parents and Children in Ukraine Study: 2023 Follow-up\" study. The latent structure of the scale was tested using confirmatory factor analysis (CFA), while convergent validity was assessed through associations with other mental health correlates. Prevalence rates of probable ICD-11 PGD were estimated. CFA results supported a correlated two-factor model (\'core\' and \'associated\' symptoms) and the internal reliability of the scale scores were acceptable. Convergent validity was supported through significant correlations with internalizing symptoms, while contact with the deceased, time since bereavement, and parental PGD were associated with higher scores on the IGQ-CG latent variables. The prevalence of probable ICD-11 PGD was 1.4%, and amongst those with a lifetime bereavement, the conditional rate was 3.2%. The IGQ-CG produces reliable and valid scores for ICD-11 PGD symptoms in children and adolescents as reported by their caregivers.
Prolonged Grief Disorder (PGD) is recognized as a grief-specific disorder included in the ICD-11. The International Grief Questionnaire (IGQ) is available to assess ICD-11 PGD symptoms in adults. However, there is no self-report measure available to assess ICD-11 PGD symptoms in children and adolescents. The researchers developed and validated a caregiver-report version of the IGQ for children and adolescents; the IGQ-Caregiver Version (IGQ-CG). Researchers found that the IGQ-CG was an accurate and consistent measure of PGD. Results showed that 1.4% of the sample met diagnostic requirements for ICD-11 PGD. The newly developed IGQ-CG can assist in the assessment and treatment of ICD-11 PGD in children and young people.
