Page 15 of the SIMS manual[4] informs the readers in an unsubstantiated manner that the SIMS items are descriptive of  “atypical, improbable, inconsistent, or illogical symptoms” that would be “highly atypical in patients with genuine psychiatric or cognitive disorders …”.  In fact, content analyses via ratings by teams of doctoral level clinicians with more than 35 years of experience each in clinical psychology or psychiatry indicated that the SIMS scales contain no items with the reasonable capacity to differentiate legitimate patients from malingerers[5,6,7,8].
