What is malingering and which tests help detect it (e.g., TOMM)?

• A. Deliberate feigning or exaggeration of symptoms for external gain; tests include TOMM and other validity measures.
• B. A mood disturbance with psychotic features.
• C. A transient cognitive impairment due to delirium.
• D. A developmental disorder with limited social interaction.

Answer: (A)

Malingering is intentional feigning or exaggeration of symptoms for external gain, such as money, time off work, legal advantage, or obtaining medications. In clinical assessments, the goal is to determine whether reported symptoms and cognitive deficits reflect genuine problems or are being produced or amplified for an outside purpose.

To detect malingering, clinicians use validity or performance-effort tests that gauge whether effort and symptom reporting are credible. The Test of Memory Malingering (TOMM) is a well-known example. It’s a quick, simple memory recognition task presented in a two-alternative forced-choice format. Because the task is designed to be easy for most people, especially those with genuine cognitive issues, someone who is deliberately feigning deficits is more likely to perform poorly or inconsistently across trials. TOMM thus serves as a check on the credibility of memory complaints: a strong TOMM performance argues against noncredible effort, while a poor TOMM performance raises suspicion of malingering, particularly when other signs point to noncredible reporting.

Keep in mind that TOMM or other validity tests are not definitive on their own; they’re used alongside interviews, behavioral observations, and other clinical data to form a complete judgment about the validity of reported symptoms.
