A Qualitative Study of the Lived Treatment Experiences of Women With an Eating Disorder and Comorbid Borderline Personality Disorder

ObjectiveHaving both an eating disorder (ED) and borderline personality disorder (BPD) is associated with heightened clinical complexity, high levels of distress, and challenges in treatment. This study sought to qualitatively investigate the experiences of women with an ED and comorbid BPD as they undergo ED treatment, aiming to better understand factors that shape their perceptions of care.MethodsFourteen women with both an ED and BPD in treatment at a public-sector ED clinic were recruited to participate in an open-ended qualitative interview about their lived treatment experiences.ResultsFive overarching themes (with seven subthemes) emerged from the qualitative analysis: (1) Difficulties with emotions as a key factor underlying both ED and BPD; (2) Perceptions of BPD in ED maintenance and treatment; (3) Relational dynamics in treatment; (4) Treatment is "never enough"; and (5) The importance of treating the ED and BPD together.DiscussionThis study highlights the lived experiences of women with both an ED and BPD. Patients expressed the need for ED treatment to target emotion dysregulation, interpersonal difficulties, and their attachment to their therapists and to treatment. This study provides insights into the experiences of patients with BPD of ED treatment that may help guide the approach to care in such individuals.
