Forensic Applications of the Miller Forensic Assessment of Symptoms Test (MFAST): Screening for Feigned Disorders in Competency to Stand Trial Evaluations

  • Published:
Law and Human Behavior

Abstract

Forensic evaluations must systematically assess malingering and related response styles. In the criminal forensic domain, competency to stand trial evaluations are the most common referrals. Effective screens for feigned incompetency would be valuable assets for forensic evaluations. This study evaluates the effectiveness of the Miller Forensic Assessment of Symptoms Test (MFAST) as a screen for feigned incompetency. Using a simulation design, the MFAST was tested on jail and competency-restoration samples. Most notably, recommended MFAST cut score (≥6) was useful for the identification of feigning cases in competency evaluations. Recommendations for forensic practice, including the advantages and disadvantages of systematic screens, are discussed.
