Factitious Disorder

Factitious Disorder involves the intentional falsification, exaggeration, or induction of physical or psychological symptoms or injury, associated with identified deception, in the absence of obvious external rewards such as financial gain or avoiding work — which would instead suggest malingering. It can be imposed on oneself, or, in a distinct and particularly serious form, imposed on another person, such as a child or dependent adult, which raises significant safety and child protection concerns.

Factitious Disorder Imposed on Self involves falsification of physical or psychological signs or symptoms, or induction of injury or disease, associated with identified deception, with the individual presenting themselves as ill, impaired, or injured, evident even without obvious external rewards. Factitious Disorder Imposed on Another involves the same pattern of falsification directed at another person — importantly, it is the perpetrator, not the victim, who receives this diagnosis.

The causes of Factitious Disorder are not fully understood. Proposed contributing factors include a history of childhood illness — one's own or witnessing a family member's — that shaped an association between being ill and receiving care or attention, and an underlying need to occupy the 'sick role' for psychological reasons unrelated to external material gain. In Factitious Disorder Imposed on Another, complex psychological dynamics in the perpetrator often involve a need for attention or sympathy through the identified role of caring for a sick dependent.

• History of significant childhood illness or hospitalization
• Family or personal history of healthcare-related work or exposure
• Underlying personality difficulties
• History of trauma or neglect
• For Factitious Disorder Imposed on Another: caregiving responsibility for the victim, frequently a parent of a young child

Factitious Disorder is less well-characterized neurobiologically than most other conditions in this library. It is understood more through psychological and developmental models involving early attachment experiences and the meaning or reward associated with the 'sick role' or caregiving role, rather than through a clearly established distinct neurobiological pathway.

• Presenting fabricated, exaggerated, or self-induced physical or psychological symptoms
• Inconsistencies in reported history or presentation that don't fit a coherent recognized illness pattern
• Seeking care from multiple providers or facilities, sometimes to avoid detection
• Reluctance to allow contact between different treating providers
• Unusual familiarity with medical terminology or procedures
• In Factitious Disorder Imposed on Another: fabricating or inducing illness in a dependent, who may undergo unnecessary and sometimes harmful medical procedures as a result

• Falsification of symptoms or induction of injury, with identified deception
• Presenting self (or another person) as ill, impaired, or injured
• Behavior evident without obvious external incentives
• Not better explained by another mental disorder
• Specified as imposed on self or imposed on another (with the perpetrator receiving the diagnosis in the latter case)

Conditions a psychiatrist will consider and rule out before confirming this diagnosis:

Malingering

Intentional symptom production is driven by a clear external incentive — such as avoiding work or obtaining financial compensation — the key distinguishing feature from factitious disorder.

Conversion Disorder / Somatic Symptom Disorder

Symptoms are genuinely, involuntarily experienced rather than intentionally fabricated or induced.

Genuine medical or psychiatric illness

Must always be carefully considered and appropriately evaluated, given the risk of missing true co-occurring illness.

• Careful, often complex clinical assessment given the inherent challenge of the deceptive presentation
• Review of medical records across multiple providers or facilities where possible
• Collaboration between treating physicians and psychiatry
• In suspected cases of Factitious Disorder Imposed on Another, involvement of child protection or adult protective services given the safety risk to the victim

Treatment is notably challenging given the inherent difficulty of engaging someone in a process that requires acknowledging deceptive behavior. A non-confrontational, supportive approach that avoids direct accusation while addressing underlying psychological needs is generally recommended. For Factitious Disorder Imposed on Another, the immediate priority is ensuring the safety of the victim, which may require protective services involvement, separate from any psychiatric treatment offered to the perpetrator.

No medication treats Factitious Disorder directly

Medications may be used for any co-occurring genuine psychiatric conditions identified, where the person is willing to engage in treatment.

Psychotherapy addressing underlying psychological needs

Often challenging to sustain given low engagement and insight.

Family therapy where relevant and safe to pursue

Particularly once safety concerns for any dependents have been addressed.

Case management coordinating across medical providers

Reduces fragmented, excessive, or risky medical care-seeking.

• Engage in any offered psychotherapy for the underlying psychological needs
• Work with a single, coordinated treatment team rather than multiple disconnected providers, where willing
• Address any co-occurring genuine psychiatric conditions

The prognosis is variable and often challenging given typically low engagement and insight. For Factitious Disorder Imposed on Another, immediate safety intervention for the victim is paramount and takes priority over the long-term treatment prognosis for the perpetrator, which is also often guarded. Some individuals, particularly with sustained, non-confrontational therapeutic engagement, do show improvement over time.

• Not well established given the complexity and rarity of the condition
• Coordinated medical records and communication between providers can help identify concerning patterns earlier
• Appropriate professional training in recognizing warning signs, particularly for Factitious Disorder Imposed on Another given the serious safety implications

For suspected Factitious Disorder Imposed on Another, the safety of the victim — often a child — is the immediate priority, requiring involvement of appropriate child protection or safeguarding services. A non-confrontational, professionally guided approach is generally recommended when addressing suspected factitious disorder in a family member, given the risk of the person becoming defensive or seeking care elsewhere if confronted directly. Support from professionals experienced in this specific, complex condition is important given how difficult and emotionally charged these situations are for families.
