Abstract
Prolonged grief disorder (PGD) is a new diagnostic category included in global diagnostic classification systems for mental disorders. However, PGD can only be diagnosed if the severity and duration exceed socio-cultural norms. Here, we present a new supplementary module to the DSM-5 Cultural Formulation Interview: the Bereavement and Grief Cultural Formulation Interview (BG-CFI). The BG-CFI was developed to help clinicians provide a culturally informed diagnosis and guide treatment planning.We investigated the feasibility, acceptability, and clinical utility of the BG-CFI. Two participant groups (11 refugees, asylum seekers or migrants experiencing bereavement and 3 clinicians) took part in the study and were interviewed using open-ended questions on measures of feasibility, acceptability, and clinical utility. A step-by-step procedure was followed: (1) Clinicians and/or researchers conducted the BG-CFI with participants; (2) Debriefing interviews were conducted separately with clinicians and with bereaved participants.The BG-CFI was found to be a feasible, acceptable, and clinically useful tool for both bereaved participants and clinicians. Where clinicians found the interview difficult to conduct (i.e. lack of conceptual clarity or triggering emotional distress) specific changes were made to the interview format such as prompts for further questioning or recommendations for withholding or adapting questions. The BG-CFI would offer a useful complement for a reliable assessment of PGD in clinical settings working with cultural incongruity.
