Area of Science:

• Psychiatry
• Psychology
• Medical Humanities

Background:

• Factitious disorder (FD) prevalence is rising, often linked with borderline personality disorder (BPD).
• Clinicians express concern regarding patients presenting with comorbid FD-BPD.

Purpose of the Study:

• To illustrate the behavioral components of Factitious Disorder and Borderline Personality Disorder comorbidity.
• To identify and describe the unique characteristics of the FD-BPD condition.

Main Methods:

• Qualitative analysis of prototypical narratives (vignettes).
• Integration of case histories, naturalistic observations, and practitioner data.
• Phenomenological and narrative methodology applied to understand FD-BPD behaviors.

Main Results:

• Fourteen case vignettes were developed, categorizing key behaviors.
• Identified behaviors include symptom inventiveness, medication misuse, and healthcare system navigation strategies.
• Observed patterns include symptom ambiguity, conflicts with healthcare providers, and frequent hospitalizations.

Conclusions:

• Narrative analysis and naturalistic observation identified a distinct FD-BPD comorbid presentation.
• This study offers novel insights into the behavioral aspects of FD-BPD, a condition gaining clinical attention.
• Findings contribute to a clearer understanding of this complex comorbidity in psychiatric and medical settings.
