Childhood trauma has been reported to be associated with severe course of illness, insecure attachment, and lower resilience in bipolar disorder. We aimed to examine the impact of childhood trauma on resilience and possible mediating role of attachment on this impact in bipolar disorder.
The study group comprised of 110 remitted patients with bipolar disorder. Hamilton Depression Rating Scale (HAM-D) and Young Mani Rating Scale (YMRS) are administered to verify remission. Childhood trauma questionnaire (CTQ-SF), Experiences in Close Relationships-revised (ECR-R), and Resilience Scale for Adults (RSA) scales administered to all patients.
More than half of patients in bipolar disorder group reported childhood trauma. HAM-D scores were positively associated with childhood trauma total scores and emotional abuse scores, negatively associated with resilience, with attachment-related anxiety. Total childhood trauma scores were associated with lower scores of resilience, higher scores of attachment-related anxiety and avoidance. Resilience scores were negatively associated with attachment-related anxiety and avoidance. Impact of childhood trauma on resilience was partly mediated by attachment-related anxiety and avoidance, respectively.
The cross-sectional design of this study is a limitation in terms of determining causality of the identified relationships.
Childhood traumas are associated with lower resilience and higher attachment-related anxiety and avoidance. Attachment-related anxiety and avoidance partly mediated the negative effect of childhood trauma on resilience. Since resilience is associated with increased quality of life in bipolar disorder, it might be helpful to develop attachment-informed psychosocial interventions to ameliorate the detrimental effect of childhood trauma on resilience.
