Measuring Grief in the Context of Traumatic Loss: A Systematic Review of Assessment Instruments

Following traumatic loss, defined as the death of a loved one due to unexpected or violent circumstances, adults may experience a myriad of grief-related problems. Given the addition of Prolonged Grief Disorders into the Diagnostic and Statistical Manual for Mental Disorders Fifth Edition, Text-Revision and influx of unexpected deaths due to the global Coronavirus pandemic, there is heightened interest in the measurement of grief-related processes. We conducted a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify measures of grief used in studies of adults who experienced traumatic loss. Searches yielded 164 studies that used 31 unique measures of grief-related constructs. The most commonly used instrument was the Inventory of Complicated Grief-Revised. Half of the measures assessed constructs beyond diagnosable pathological grief responses. Given the wide variation and adaptations of measures reviewed, we recommend greater testing and uniformity of measurement across the field. Future research is needed to adapt and/or design measures to evaluate new criteria for Prolonged Grief Disorder.
