Narrative coherence of autobiographical memories in women with borderline personality disorder and associations with childhood adversity

Abstract

Background: People suffering from Borderline Personality Disorder (BPD) seem to have incoherent autobiographical narratives. Tentative evidence suggests that reduced narrative coherence of autobiographical memories is associated with insecure attachment. However, it remains unknown whether incoherent autobiographical narratives in people with BPD are coupled to experiences of childhood trauma, which is highly prevalent in BPD. Method: We examined if written autobiographical memories in 26 female participants with BPD had reduced narrative coherence relative to 28 healthy female controls and whether more incoherent narratives were associated with childhood trauma. Results: As hypothesized, results showed that compared to controls, the autobiographical memories in participants with BPD had reduced narrative coherence, specifically inadequate orientation about the narrative and lack of narrative structure. More self-reported childhood adversity was coupled to lower orientation across groups whereas increased childhood adversity showed a specific relationship to lowered narrative structure in BPD participants. Conclusion: Women with BPD had incoherent autobiographical narratives, and reduced narrative coherence was associated with more self-reported childhood adversity, which appeared to explain the group differences.
