Prolonged grief and attachment security: A latent class analysis

Abstract

The death of a loved one has been associated with a wide range of mental health outcomes. Attachment theory is one of the primary paradigms for understanding bereavement outcome, yet there is comparatively little examination of the relationship between attachment style and bereavement responses. In this study we use Latent Class Analysis to identify subgroups of bereaved individuals based on patterns of prolonged grief (PG) and major depression symptom co-occurrence in 285 bereaved individuals. We then explored the relationship between these subgroups and attachment anxiety and avoidance. Three new subgroups of individuals were identified: one showing high levels of PGD and depression (PGD/depression), one showing high depression (Depression), and one showing few symptoms (Low). Attachment anxiety significantly differentiated between the three groups; the highest levels of attachment anxiety predicted membership of the PGD/depression group, the lowest levels, membership of the Low group. Attachment avoidance was predictive of greater depressive symptoms, with higher levels of attachment avoidance differentiating the two symptom groups (PGD/depression and depression) from the Low symptom group. These findings underscore the relevance of insecure attachment style to the current understanding of PGD.
