Randomized trial assesses SIMS diagnostic accuracy for PTSD in Israeli men, suggesting caution in interpretation.

To evaluate the accuracy of SIMS in distinguishing feigned PTSD from recognized PTSD and healthy controls.
Participants included 112 Israeli men: 38 with recognized PTSD, 34 healthy controls, and 40 instructed feigning.
Evaluations included SIMS, TOMM, PCL-5, and BFI, with a focus on sensitivity and specificity.
Correlations were analyzed between PTSD symptom severity, neuroticism, and SIMS scores.
SIMS showed 85% sensitivity for detecting feigned PTSD and 61% specificity in recognized PTSD cases.
All healthy controls scored below the SIMS cutoff, achieving 100% specificity.
PTSD symptom severity was positively correlated with both SIMS total score (r = .62, p < .01) and neuroticism (r = .54, p < .01).
