Compares diagnostic accuracy of self-reported and clinician-evaluated PTSD in veterans, indicating screening tool limitations.

Key Points

This research aims to compare the effectiveness of self-reported and clinician-administered assessments for PTSD and CPTSD symptoms using two specific tools.
Sample of 108 Danish veterans completed both the ITQ and ITI.
Descriptive statistics and bivariate correlations were calculated to assess agreement.
Cohen's κ values determined the agreement levels for symptom items and diagnostic categories.
Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated.
ITQ scores were consistently higher than ITI scores across all symptom domains.
Strong associations between instruments for total symptom scores (r = .74 to .82, all p < .001).
Agreement for individual symptom items varied from fair to substantial (κ = .33 to .70).
Moderate agreement for combined diagnosis of PTSD or CPTSD (κ = .60) with high sensitivity (0.94) and PPV (0.90).
Fair agreement for ICD-11 PTSD alone (κ = .38) with low PPV (0.39) but good sensitivity (0.65).
