Bereavement guilt among young adults impacted by caregivers' cancer: Associations with attachment style, experiential avoidance, and psychological flexibility

Objectives. This paper focuses on the experiences of bereavement guilt among young adults bereaved by a caregiver's cancer, examining associations with attachment style, experiential avoidance, and psychological flexibility with the aim of informing psychosocial interventions for this population. Methods. Ninety-seven young adults (18-25 years) bereaved by a parent/guardian's cancer completed an online survey, including measures of bereavement guilt, attachment style, experiential avoidance, and psychological flexibility. Mediation analyses explored the associations between attachment style (anxious, avoidant) and bereavement guilt, and if these associations were mediated by experiential avoidance or psychological flexibility. Results. Bereavement guilt was significantly positively associated with anxious, but not avoidant, attachment to the deceased; the relationship between anxious attachment and bereavement guilt was partially mediated by experiential avoidance. Bereavement guilt was also negatively associated with psychological flexibility and engagement with bereavement counseling. Significance of results. Given the limited literature on cancer-related bereavement in young adulthood, this study offers important theoretical and clinical insights into factors associated with more complex aspects of grief in this population. Specifically, this work identified that anxious attachment is associated with ongoing bereavement complications in the years following the death of a caregiver to cancer, with experiential avoidance partially mediating this relationship. While further research is needed to better understand the interaction between these factors and other related constructs, such as psychological flexibility, these findings may be helpful in selecting therapeutic approaches to use with this population.
