Simulation in forensic contexts: diagnostic challenges and assessment strategies

Simulation in forensic psychology is defined as the conscious imitation of psychological or psychiatric symptoms with the aim of obtaining an external benefit, such as avoiding legal sanctions, obtaining compensation or influencing legal proceedings. This phenomenon, distinct from dissimulation and factitious disorder, can take several forms: pure simulation, oversimulation and metasimulation. Risk factors include personality profiles such as antisocial and histrionic disorder, as well as judicial, occupational and civil contexts where there are clear incentives to simulate. Forensic assessment of simulation differs from clinical assessment in its objective approach and the need to detect potential deception, using structured interviews, psychometric tests (such as MMPI-2, SIMS, TOMM, and SIRS), and collateral sources to identify discrepancies and overreactions. However, screening presents challenges, such as the risk of false positives and negatives, the sophistication of simulating strategies, and the need for ongoing training for practitioners. The legal implications of simulation can include criminal and civil penalties, as well as revocation of fraudulently obtained benefits. Ethically, the forensic psychologist must act with rigor, objectivity and transparency, documenting his or her findings and defending his or her conclusions in court. Specialized training, research into new detection techniques and interdisciplinary collaboration are recommended to improve the reliability of evaluations and contribute to justice in legal proceedings.
