Grief and growth of bereaved siblings as related to attachment style and flexibility.

This study examined the relationship between attachment style, coping flexibility, military/non-military cause of death, levels of grief reactions and posttraumatic growth (PTG), in 150 bereaved adult siblings in Israel. Insecurely attached participants, 72% of the sample, reported more grief and less PTG than did securely attached ones. Highly avoidant individuals exhibited the least amount of PTG. Securely attached siblings were more flexible and flexibly coping participants reported less grief and higher PTG. Cause of death was not related to grief and PTG. Discussion of these findings yields conditions enabling PTG after a sibling loss.
