Clinical, demographic, psychological, and behavioral features of factitious disorder: A retrospective analysis.

BACKGROUND: Consultation psychiatrists are often asked to assess factitious disorder (FD), yet this is challenging as confirmation depends on rarely achieved direct evidence of illness-inducing behaviors. Diagnosis is thus based on other variables, such as atypical features of the medical presentation and certain patient behaviors. This study sought to assess a cohort of patients with FD for demographic and clinical variables, but also psychological and behavioral ones unexamined in previous studies.

METHODS: 49 previously-identified FD patients at a single site were reviewed retrospectively and variables collected included demographic, medical, psychiatric, social, behavioral, and treatment-related. Descriptive statistical analysis was used.

RESULTS: Patients were mostly: 1) under age 40 (82%), 2) female (90%), 3) with past psychiatric (92%), family psychiatric (78%), and traumatic (69%) histories; 4) direct intravenous access (67%); and 7) some exposure to healthcare training (67%). All (100%) subjects had an identifiable family dynamic issue, including household abuse, parental divorce, parental influence/enmeshment, grief, and/or significant other conflict. Financial, emotional, or social incentives were common, and most patients (88%) exhibited at least 4 FD-related behaviors.

CONCLUSION: FD represents a complex disorder of abnormal illness behaviors with predisposing developmental and perpetuating sociobehavioral variables previously unexplored. Future investigational, educational, and quality improvement directions are considered.
