The present study sought to cross validate the recently developed total score cut-off for the Beck Depression Inventory-II (BDI-II) and identify additional embedded symptom validity indices within this commonly used self-report depression measure. Study 1 included a research sample of 379 veterans with diagnostic subgroups of Current and Lifetime Depression and Current and Lifetime Posttraumatic Stress Disorder (PTSD). Study 2 included a clinical sample of 224 veterans with diagnostic subgroups of Current Depression, Lifetime Depression, and No Depression.

Article Synopsis
- Anxiety disorders are the most common psychiatric issues in the U.S., but current assessment tools lack validity measures, which the study aimed to address by creating a symptom validity index for the Beck Anxiety Inventory (BAI).* -
- The study involved 244 veterans and categorized them into valid and invalid response groups, identifying a cutoff score of ≥ 29 for the overall sample to distinguish valid responses, although specific clinical subgroups required higher cutoffs.* -
- The research is significant as it's the first to establish a symptom validity index for the BAI, recommending a total score of ≥ 36 to reduce false positives when evaluating current anxiety symptoms.*
Exploration of PCL-5 symptom validity indices for detection of exaggerated and feigned PTSD.

Article Synopsis
- - The study aimed to create and validate new symptom validity indices for the PTSD Checklist for DSM-5 (PCL-5), addressing a gap in tools for assessing overreported PTSD symptoms in patients, especially veterans.
- - Researchers tested three indices (PSS, PES, PRI) using a sample of 210 veteran patients, comparing their responses against established validity measures to categorize them as valid or invalid responders.
- - Results showed promising accuracy for the PSS and PES indices, with the PES achieving the highest sensitivity when focused on patients with strong evidence of invalidity, indicating these new indices could be useful for better PTSD assessment.
Objective: This investigation was designed to examine the classification statistics of Memory Complaints Inventory (MCI) scores relative to the Medical Symptom Validity Test (MSVT) and the Non-Verbal Medical Symptom Validity Test (NV-MSVT), as well as various validity scales on the Personality Assessment Inventory (PAI) and Minnesota Multiphasic Personality Inventory-2 Restructured Form(MMPI-2-RF).
Method: The sample consisted of 339 active duty service members with a history of concussion who completed performance validity tests (PVTs), symptom validity tests (SVTs), and the MCI.
Results: Those who failed the MSVT and NV-MSVT had significantly higher scores across all MCI scales.
