Eye Movement Desensitization and Reprocessing Therapy and Change in Attachment Security: A Pilot Study

Eye movement desensitization and reprocessing (EMDR) therapy has a rapidly growing evidence base; however, research into changes in attachment security during EMDR therapy is limited. This pilot study aimed to explore changes in attachment security in a clinical sample of adults who received EMDR therapy for symptoms of posttraumatic stress disorder (PTSD) and complex posttraumatic stress disorder (CPTSD). It also explored the quality of the therapeutic alliance in relation to changes in attachment security. A within-subject, repeated-measures design was used. Eighteen participants received fifteen EMDR sessions on average and completed self-report measures of attachment, PTSD, CPTSD, and therapeutic alliance. A decrease in attachment insecurity was observed. Changes in attachment security were partially associated with the quality of the therapeutic alliance and changes in symptomatology. This study contributes to the emerging literature on change in attachment security and EMDR therapy.
