Abstract

This systematic review was performed to summarize existing research on the symptom validity scales within the Trauma Symptom Inventory-Second Edition (TSI-2), a relatively new self-report measure designed to assess the psychological sequelae of trauma. The TSI-2 has built-in symptom validity scales to monitor response bias and alert the assessor of non-credible symptom profiles. The Atypical Response scale (ATR) was designed to identify symptom exaggeration or fabrication. Proposed cutoffs on the ATR vary from ≥ 7 to ≥ 15, depending on the assessment context. The limited evidence available suggests that ATR has the potential to serve as measure of symptom validity, although its classification accuracy is generally inferior compared to well-established scales. While the ATR seems sufficiently sensitive to symptom over-reporting, significant concerns about its specificity persist. Therefore, it is proposed that the TSI-2 should not be used in isolation to determine the validity of the symptom presentation. More research is needed for development of evidence-based guidelines about the interpretation of ATR scores.
