Comorbidity Between Factitious and Borderline Personality Disorder: A Narrative Analysis.

Abstract

Factitious disorder (FD) illnesses have increased recently, primarily due to comorbidity with borderline personality disorder (BPD). Psychiatrists, hospital doctors, and general practitioners are interested in and concerned about patients with comorbid FD-BPD. We used a qualitative analysis of prototypical narratives collected as vignettes by merging individual contributions, case histories, naturalistic observations, and data from mental health practitioners into specific descriptions. Our study used a phenomenological and narrative method to illustrate the contents and behaviours in FD-BPD comorbidity. Fourteen case vignettes were created from our case studies. These categories included knowledge of symptoms and medical terms, dramatisation, symptoms ambiguity, unexplainable deterioration of symptoms, symptom inventiveness, craving for painkillers, conflicts with health carers, hospital migration, piling of medication and search for invasive diagnostic procedures. The combined use of narrative analysis and naturalistic observation has helped identify a unique comorbid condition of FD-BPD, which is not yet clearly described in its behavioural components by the international literature. The current study presents novel findings into a condition becoming progressively popular in psychiatric and medical settings.
