Military-bereaved siblings’ growth and distress–Interplays between interpersonal factors and commemoration

Sibling bereavement due to military casualties can produce psychological distress but can also elicit personal growth. This research explored the association between psychological distress and post-traumatic growth (PTG) among military-bereaved siblings via a moderated mediation model. Israeli military-bereaved siblings were recruited through a nonprofit organization devoted to bereaved siblings of military casualties. Participants (N = 155) completed questionnaires of posttraumatic growth, distress, commemoration, social support. Results supported the moderated mediation study model. Specifically, higher psychological distress was associated with lower social support, which was subsequently associated with lower self-disclosure, for the entire sample. This association was strongest for bereaved siblings with high relief-related commemoration, which was then associated with lower PTG. Pursuant to our findings, mental health professionals need to guide bereaved siblings toward involvement in commemoration activities that bring them relief, thus further enabling social support that facilitates personal disclosure and, subsequently, PTG.
