Overview

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

Key Points

  • 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).
