Screening for Malingering in a Correctional Setting

This study outlines the development of the Screening SIRS, an abbreviated version of the Structured Interview of Reported Symptoms (SIRS), for use as a screening measure of malingering in a correctional setting. Seventy-five inmates complaining of psychological impairment were tested for malingering. A subset of the participants was given both the original SIRS and the Screening SIRS as a separate test with the test order counterbalanced; the remainder were given the original SIRS and a derived classification was determined by extracting the Screening SIRS scale scores. Using Receiver Operating Characteristic analyses, classification based on the Screening SIRS was significantly better than chance. With a sensitivity of 87% and specificity of 73%, the Screening SIRS was highly predictive of classifications based on the original SIRS. These findings have instrumental implications in correctional settings where identification of possible malingerers through a screening procedure may facilitate optimal allocation of resources.
