Common questions
What is the MAL index used for?+
MAL is a supplementary index within the PAI (Personality Assessment Inventory) designed to detect feigned psychopathology in forensic settings. It uses a configuration-based approach alongside other clinical scales to identify when someone is exaggerating or fabricating psychological symptoms.
Who should be given the MAL index?+
The MAL index is specifically developed for forensic populations, including those undergoing court evaluations, competency assessments, or criminal proceedings. It helps evaluators distinguish genuine mental health conditions from deliberate symptom exaggeration in high-stakes legal contexts.
How does MAL work with other tests?+
MAL is not a standalone test but works as a supplementary index alongside the PAI's main clinical scales and other malingering indicators like the NIM (Negative Impression Management scale). Using multiple detection methods together strengthens the validity of the forensic assessment.
