Grief Impairment Scale: A biopsychosocial measure of grief-related functional impairment

When does disruption of meaning in bereavement become debilitating? Screening for deleterious outcomes with the ISLES-SF

Meaning reconstruction is a central process in bereavement adaptation. However, clinical measures or means for identifying individuals whose struggles with meaning making have become dysfunctional have yet to be developed for clinicians to readily use in practice. Therefore, the objective of this study was to evaluate the diagnostic effectiveness of the Integration of Stressful Life Experiences Scale-Short Form (ISLES-SF) for measuring clinically significant struggles with meaning making of loss. The results of this study of 118 bereaved adults support the diagnostic use of the ISLES-SF (sensitivity of 83% and specificity of 73%), as well as an identified cut-score (≥ 14) that researchers and clinicians can employ to accurately and efficiently identify those whose difficulties with making meaning of loss have become debilitating. The results also showed that those who scored in the clinical range of the ISLES-SF displayed higher levels of anxiety, depression and prolonged grief than those not struggling with meaning making.

Prevalence and Co-Occurrence of Psychiatric Conditions Among Bereaved Adults

Importance

Rates of grief-related psychiatric conditions, such as prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), and major depressive disorder (MDD), among bereaved adults in the US are largely unknown due to limited studies that leverage national samples.

Objective

To assess risk factors for and prevalence rates and co-occurrence of PGD, PTSD, and MDD among bereaved adults in the US.

Design, Setting, and Participants

Data for this survey study were collected from a large US panel sample between October 10 and 28, 2022, using a web-based survey. Participants were aged 18 years or older and were proficient in English. Data analysis was conducted between March and June 2023.

Main Outcomes and Measures

Probable psychiatric conditions were assessed with validated measures that used conservative cutoff scores, duration, and impairment criteria. These measures included the revised Prolonged Grief Disorder scale for PGD, the PTSD Checklist for DSM-5 for PTSD, and the Patient Health Questionnaire-9 for MDD. Data were analyzed using basic descriptives and logistic regression.

Results

A total of 2034 adults (n = 1529 and 505 in the bereaved and comparison groups, respectively) completed the study. Respondents had a mean (SD) age of 40.7 (15.9) years; the majority were women (1314 [64.6%]) and had at least some college experience (1394 [68.5%]). With regard to race and ethnicity, 392 respondents (19.3%) were Black, 138 (6.8%) were Hispanic, and 1357 (66.7%) were White. Among bereaved adults, 312 (20.4%), 518 (33.9%), and 461 (30.2%) met criteria for a presumptive diagnosis of PGD, PTSD, and MDD, respectively. Comorbidities were common, with 441 participants (28.8%) meeting criteria for at least 2 co-occurring disorders. Comorbid PGD, PTSD, and MDD were more common than any 2 co-occurring or isolated disorders; the presence of co-occurring conditions was more likely among respondents who reported a traumatic loss. Age and educational attainment were associated with the risk of psychiatric conditions; less time since the index death, loss of a psychologically close other, and a traumatic loss experience were associated with increased risk of PGD, PTSD, and MDD or their co-occurrence.

Conclusions and Relevance

In this study, the majority of bereaved adults did not meet presumptive criteria for PGD, PTSD, or MDD. Nevertheless, PGD, PTSD, and MDD were highly prevalent and comorbid, particularly among those who experienced traumatic loss. These findings underscore the need for integrated psychological care that leverages transdiagnostic mechanisms of evidence-based practice.

New Psychometric Evidence of the Grief Impairment Scale (GIS) in People Who Have Experienced the Death of a Loved One From a Network Psychometric Approach in Two Latin American Countries

This study aimed to evaluate the psychometric properties of the Grief Impairment Scale (GIS) using a network psychometric model. A total of 1048 individuals from Peru and El Salvador participated. A network psychometric model was used to determine internal structure, reliability, and cross-country invariance. The results indicate that the GIS items were grouped into a single network structure through Exploratory Graph Analysis. Reliability was estimated by structural consistency, and it was found that when replicating the network structure within an empirical dimension, a single network structure was consistently obtained, and all items remained stable. Furthermore, the network structure was invariant, thus functioning similarly across the different country groups. In conclusion, the GIS presented solid psychometric evidence of validity based on its internal structure, reliability, and cross-country invariance. Therefore, the GIS is a psychometrically sound measure of functional impairment symptoms due to grief for Peruvian and Salvadoran individuals.

The Impact of COVID-19 on Grief: A Quantitative and Qualitative Analysis in Italy

This mixed-method research study delves into the repercussions of the COVID-19 pandemic on loss and mental health in Italy. The analysis uncovers a significant correlation between COVID-19 fear and heightened anxiety, depression, and stress, exacerbated by social isolation and misinformation. The loss of loved ones during the pandemic intensifies distress, with 28% showing signs of prolonged disorder and 22.8% displaying maladaptive grief symptoms. Distress persists across pandemic phases (59.3% critical, 54.9% intermediate, 48.4% less critical), attributed to grief, fear, uncertainty, and isolation. Qualitative analysis identifies two core themes: 'Death without Dying' and 'Online Grieving Practices and Coping Strategies,' elucidating disruptions to traditional grieving and the role of online coping strategies. Our findings underscore the pandemic's multifaceted impact on grief and mental health in Italy, highlighting the importance of addressing social and emotional needs during crises.

Psychometric properties of the Persian version of the Grief Impairment Scale

This study validated a Persian translation of the Grief Impairment Scale (GIS) in a sample of 548 grieving Iranian adults. Researchers recruited participants online using convenience and targeted sampling and asked them to complete the GIS and other measures. Of the 548 participants, 150 completed the scales again at Time 2 after one month using anonymous identifiers. Confirmatory factor analysis supported the unidimensionality of the Persian GIS. Measurement invariance held across gender. The GIS demonstrated good internal consistency (ω = .86) and test-retest reliability (ICC =.842). Convergent validity was evidenced by strong correlations with measures of prolonged grief and functional impairment. Divergent validity was supported by weaker correlations with anxiety and depression. A cut-score of ≥ 7 yielded good sensitivity (87%) and specificity (71%) in identifying those with significant functional impairment from grief. The Persian GIS demonstrated excellent psychometric properties as a brief tool for assessing grief-related impairment.

A Psychometric Analysis of the Spanish Version of the Grief Impairment Scale: A Screening Tool of Biopsychosocial Grief-Related Functional Impairment in a Salvadoran Sample

The objective of this study was to translate and psychometrically evaluate a Spanish version of the Grief Impairment Scale (GIS) using a sample of bereaved adults from El Salvador (N = 579). The results confirm the unidimensional structure of the GIS, and solid reliability, item characteristics, and criterion-related validity, where the GIS scale significantly and positively predicts depression. However, this instrument only showed evidence of configural and metric invariance between different sex groups. Overall, these results support the Spanish version of the GIS as a psychometrically sound screening tool for health professionals and researchers to use in their clinical work.
