Interpersonal theory dimensions facilitate posttraumatic growth among suicide-loss survivors: An attachment perspective.

Many studies have highlighted the deleterious psychological impact of suicide on bereaved individuals. We examined the psychological processes facilitating posttraumatic growth (PTG) among 124 suicide-loss survivors, focusing on attachment styles, perceived burdensomeness, and thwarted belongingness. Securely attached individuals achieved higher PTG than insecurely attached individuals. Perceived burdensomeness and thwarted belongingness both mediated and moderated the associations between attachment and PTG. Anxiously or avoidantly attached individuals who also had a high level of perceived burdensomeness were the least likely to achieve PTG. Thus, these individuals may derive particular benefit from attachment-based therapeutic interventions focusing on interpersonal relationships.
