Bereavement has been associated with a number of adverse outcomes, including mortality, particularly among those who experience the sudden loss of a close other. With rising rates of sudden death in the United States, fueled by an alarming increase in fatal overdose deaths, identifying bereavement-related needs among the sudden-death bereaved is essential. The present study investigated the factor structure, internal reliability, and validity of the Sudden Bereavement Needs Inventory (SBNI) in a sample of sudden loss survivors (i.e., fatal overdose, suicide, and sudden-natural loss; N = 403). Confirmatory factor analysis supported a six-factor structure, with items reflecting pragmatic, informational, spiritual, relational, meaning, and emotional needs. SBNI factors showed adequate internal consistency, with significant associations between SBNI scores, loss characteristics, and mental health outcomes (e.g., prolonged grief symptoms, meaning-making, posttraumatic stress disorder [PTSD] symptoms, and anxiety), supporting the scale's validity and highlighting the potential applicability of the instrument in both research and clinical contexts. Future research should examine test-retest reliability of the SBNI, particularly through the lens of understanding whether and how bereavement needs change over time.
