[Simulation of mental illness]

Area of Science:

• Psychiatry
• Criminology
• Forensic Psychology

Context:

• Simulation is defined by the DSM-IV-TR as intentional production of false or exaggerated physical/psychological symptoms for external incentives.
• It has a near-zero prevalence in the general population, occurring predominantly in forensic psychiatric settings, among individuals facing legal proceedings, or those with criminologically deviant personalities.

Purpose:

• To review diagnostic criteria and suspicion indicators for simulation, dating back to Foreal and Kaufman (1943).
• To explore related concepts such as self-injurious actions (Bachler), associationist/mechanistic theories, and differential diagnoses.
• To conclude with a discussion on 'Premeditation' in the context of simulation.

Summary:

• The abstract outlines the definition and low prevalence of simulation, emphasizing its occurrence in forensic populations.
• It details the review of diagnostic criteria, suspicion indicators, and differential diagnoses relevant to psychiatric and criminological contexts.
• The work also incorporates theories on self-injury and classical dynamic models, concluding with 'Premeditation'.

Impact:

• Provides a comprehensive overview of simulation within forensic and psychiatric contexts.
• Clarifies diagnostic challenges and differential considerations for clinicians and legal professionals.
• Contributes to understanding malingering and its implications in legal and psychiatric evaluations.
