The Persistent Complex Bereavement Inventory: A Measure Based on the DSM-5.

The Persistent Complex Bereavement Inventory (PCBI) was developed to facilitate research into the construct of persistent complex bereavement disorder (PCBD). Across 2 studies, the PCBI yielded a stable 3-factor structure that corresponded with DSM-5 criteria for PCBD. The PCBI demonstrated solid reliability in the forms of internal consistency and test-retest reliability. Correlation analyses provided evidence of the measure's construct, convergent, and divergent validity. The PCBI predicted outcomes, above and beyond measures of prolonged grief disorder, separation anxiety, depression, and post-traumatic stress. In addition, the Social/Identity Disruption subscale was able to predict future negative religious coping, harmful health behaviors, hallucinations, somatic complaints, medical conditions, and suicidal ideation. This article provides preliminary evidence for a reliable and valid way to measure PCBD symptomatology.
