The M-FAST consists of 25 structured questions designed to assess the likelihood of malingering․ Each item targets specific symptoms or response styles associated with feigned mental illness․ The interview is divided into categories, such as reported symptoms, inconsistencies, and exaggerated responses, to systematically evaluate potential malingering․ Questions are rationally derived from research on malingering detection strategies, ensuring a focused and efficient assessment; The format allows for quick administration, typically within 5-10 minutes, making it a practical tool in forensic and clinical settings․ A score of 6 or higher suggests potential malingering, guiding further evaluation․
2․2․ Administration Time and Format
The M-FAST is a 25-item screening interview designed for efficient administration, typically requiring 5 to 10 minutes to complete․ It is structured as a verbal interview, ensuring clarity and consistency across administrations․ The format is straightforward, with each question targeting specific indicators of malingering․ This brevity makes it ideal for use in forensic and clinical settings where time is limited․ The M-FAST is intended for adults and is commonly administered in criminal justice evaluations, civil proceedings, and neuropsychological assessments, providing a reliable initial screening for potential malingering․
2․3․ Scoring Criteria and Interpretation
The M-FAST utilizes a straightforward scoring system, with each of the 25 items contributing to a total score․ Items are scored as either 0 or 1, based on the respondent’s answers, with higher scores indicating a greater likelihood of malingering․ A cutoff score of 6 or higher suggests potential feigning of psychiatric symptoms․ Interpretation involves evaluating the total score within the context of the individual’s circumstances and may warrant further assessment with more comprehensive tools to confirm malingering․ This scoring system ensures clarity and consistency in clinical and forensic applications․
Development and Validation of the M-FAST
The M-FAST, developed by Miller in 2001, is based on validated response styles to detect malingered symptoms․ Its 25-item structured interview ensures reliable detection of feigned psychiatric illness․
