Common questions

Why does the model insist on at least two data sources before a malingering conclusion?+

A single test or interview can produce an elevated score for reasons unrelated to deliberate feigning, such as genuine severe psychopathology or reading difficulty, so convergence across independent sources reduces the risk of a false malingering classification.

What are examples of alternative hypotheses the model requires examiners to rule out?+

Genuine mental disorder, cognitive impairment, cultural or language factors affecting test performance, and factitious presentation are typical alternatives an examiner must consider before concluding a response pattern reflects deliberate malingering.

How does this model differ from relying solely on a single validity scale cutoff?+

A cutoff score treats one instrument's result as decisive, while Rogers' framework requires integrating multiple instruments and interview data and weighing competing explanations, which produces a more defensible clinical opinion under cross-examination.
