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

Prolonged grief disorder in an inpatient psychiatric sample: psychometric properties of a new clinical interview and preliminary prevalence

BACKGROUND

Prolonged Grief Disorder (PGD) was newly included in the ICD-11 and DSM-5-TR. It is not yet part of the standard assessments in many healthcare systems, including psychiatric wards. Because disordered grief is associated with suicidality, sleep problems and substance use disorders, an investigation into PGD in psychiatric inpatients is warranted.

METHOD

We interviewed N = 101 psychiatric inpatients who were admitted to the open psychiatric wards and the day hospital of a German psychiatric hospital and who had lost a person close to them. Assessments comprised clinical interviews and self-report instruments covering PGD and other mental disorders. We specifically developed the International Interview for Prolonged Grief Disorder according to ICD-11 (I-PGD-11) for the study and examined its psychometric properties.

RESULTS

The prevalence rate of PGD among bereaved patients according to ICD-11 was 16.83% and according to DSM-5-TR 10.89%. The I-PGD-11 showed good psychometric properties (Mc Donald's ω = 0.89, ICC = 0.985). Being female, having lost a child or spouse, and unnatural or surprising circumstances of the death were associated with higher PGD scores.

TRIAL REGISTRATION

Approval was obtained by the ethics committee of the of the Goethe University Frankfurt (2021-62, 2023-17) and the Chamber of Hessian Physicians (2021-2730-evBO). The study was preregistered ( https://doi.org/10.17605/OSF.IO/K98MF ).

LIMITATIONS

We only assessed inpatients of one psychiatric clinic in Germany, limiting the generalizability of our findings.

CONCLUSION

The present study underlines the importance of exploring loss and grief in psychiatric inpatients and including PGD in the assessments. Given that a significant minority of psychiatric inpatients has prolonged grief symptoms, more research into inpatient treatment programs is needed.

Grief and delivering a statement in court: a longitudinal mixed-method study among homicidally bereaved people

Background: Participating in a criminal trial may increase the likelihood of developing psychopathology. In 2021, people bereaved by a plane disaster (flight MH17) had the opportunity to deliver a victim personal statement (VPS) in Dutch court.Objective: This longitudinal mixed-method study examined different aspects of 84 bereaved people's experiences with VPS delivery.Method: Motivations to deliver, or not deliver, an oral VPS were examined qualitatively using thematic content analysis. Whether background and loss-related variables were related to the decision to deliver a VPS was examined using binary logistic regression analyses. Between-group (delivered VPS vs. did not) and within-group (pre- vs. post-VPS) comparisons were made regarding prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), and depression levels using t-tests and paired t-tests.Results: Bereaved people were most frequently motivated to deliver an oral VPS to describe the impact of the incident, while those who did not deliver an oral VPS commonly wanted to protect themselves from the perceived emotional burden. None of the correlates - i.e. biological sex, age, level of education, number of losses, and (closest) relationship to the deceased - were related to the decision to deliver a VPS. Lastly, significantly higher PGD, PTSD, and depression levels were reported by people who delivered a VPS than those who did not, before and after the court hearing. No significant within-group differences were found over time.Conclusions: Professionals may provide emotional support to bereaved people who want to deliver a VPS and manage their expectations if they want to deliver a VPS for the purpose of symptom reduction. Future research may benefit from examining other ways in which VPS delivery might have beneficial or detrimental effects for specific individuals. Overall, implementing VPS delivery in court on the basis of emotional restoration remains empirically unsupported, if defined as a reduction in psychopathological levels.

Interpersonal psychotherapy for comorbid prolonged grief disorder and persistent depressive disorder in a Japanese patient: A case report

Background

Prolonged grief disorder (PGD) is a new diagnostic entity. However, treatment for PGD is not yet available. Interpersonal psychotherapy (IPT) may be effective for PGD.

Case Presentation

A single 27-year-old Japanese woman lost her brother to suicide. However, she did not express her grief to anyone or visit a psychiatric clinic. After experiencing strong depressive symptoms triggered by work stress, she visited a psychiatric clinic, where she was diagnosed with depression as well as PGD. Through pharmacotherapy, her depressive symptoms improved, but no improvement was noted in her PGD symptoms. She therefore began IPT for PGD at our hospital, 5 years after her brother's suicide and after 4 years of PGD symptoms. In the introductory phase of IPT, she was diagnosed with comorbid persistent depressive disorder (PDD). After this diagnosis, through psychoeducation on PDD, she could identify the symptoms that reflected her personality traits as "PDD symptoms." Furthermore, she could affirm her positive and negative feelings and share them with others. Consequently, the grieving process was facilitated, and her interests and relationships were re-established. Her PGD and PDD symptoms improved.

Conclusion

IPT may be effective for PGD comorbid with PDD among Japanese.

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.
