Evaluation of the performance of instruments to diagnose grief disorders: A diagnostic meta-analysis

BACKGROUND

Prolonged or complicated grief disorder occurs in 9.8% of bereaved adults and can progress into adverse health effects if left unresolved. Evidence on the appropriate and specific diagnostic instrument for the assessment of prolonged or complicated grief disorders is lacking.

OBJECTIVE

The purpose of this study was to evaluate the performance of the most widely used instruments to diagnose grief disorders, including The Inventory of Complicated Grief, The Inventory of Complicated Grief - Revised, and the Prolonged Grief Disorder-13.

DESIGN

Diagnostic meta-analysis.

DATA SOURCES

PubMed, EMBASE, CINAHL, Medline, Scopus, Web of Science, and Cochrane were searched up to July 1, 2020.

METHODS

We included studies evaluating the sensitivity and specificity of grief disorders diagnostic tools against the comparator tests in individuals who experienced the loss of a family member. A diagnostic meta-analysis of pooled sensitivity and specificity, likelihood ratios, and area under curve were performed with a random-effect and hierarchical model.

RESULTS

In the current study, 3540 participants were involved. The six studies of the Inventory of Complicated Grief had pooled sensitivity of 0.93 (95% confidence interval: 0.87 to 0.97) and specificity of 0.96 (95% confidence interval: 0.92 to 0.98). The positive likelihood ratio was 23.4 (95% confidence interval: 11.2 to 49.0) and the negative likelihood ratio was 0.07 (95% confidence interval: 0.04 to 0.14) with area under curve value at 0.96 (95% confidence interval: 0.97 to 0.99). For Prolonged Grief Disorder-13, the three included studies' pooled sensitivity was 0.51 (95% confidence interval: 0.42 to 0.60), and the pooled specificity was 0.96 (95% confidence interval: 0.93 to 0.98). The Inventory of Complicated Grief-Revised evaluation could not be performed as only two articles from the same study were identified in this meta-analysis.

CONCLUSIONS

The Inventory of Complicated Grief is a highly recommend instrument to differentiate the case of grief disorders. Nurses and health care professionals can use the Inventory of Complicated Grief in the diagnosis of prolonged or complicated grief disorders due to its high sensitivity and specificity values. Further evaluations are needed for the use of Prolonged Grief Disorder-13 and Inventory of Complicated Grief-Revised.

The study is registered with the Open Science Framework (https://osf.io/bs8n6/?view_only=109e76e59efb4d7699153f62564f57ed). Tweetable abstract: Inventory of Complicated Grief is a highly recommend instrument with high sensitivity and specificity for diagnosing grief disorders.

The therapeutic effectiveness of using visual art modalities with the bereaved: a systematic review

Bereaved individuals are increasingly considered at risk for negative psychological and physiological outcomes. Visual art modalities are often incorporated into grief therapy interventions, and clinical application of art therapy techniques with the bereaved has been widely documented. Although clinicians and recipients of these interventions advocate for their helpfulness in adapting to bereavement, research investigating the efficacy of visual art modalities has produced equivocal results and has not yet been synthesized to establish empirical support across settings. Accordingly, this review critically evaluates the existent literature on the effectiveness of visual art modalities with the bereaved and offers suggestions for future avenues of research. A total of 27 studies were included in the current review. Meta-analysis was not possible because of clinical heterogeneity and insufficient comparable data on outcome measures across studies. A narrative synthesis reports that therapeutic application of visual art modalities was associated with positive changes such as continuing bonds with the deceased and meaning making. Modest and conflicting preliminary evidence was found to support treatment effectiveness in alleviating negative grief symptoms such as general distress, functional impairment, and symptoms of depression and anxiety.
