PTSDdiag: Optimize PTSD Diagnostic Criteria
Provides tools for analyzing and optimizing PTSD (Post-Traumatic
Stress Disorder) diagnostic criteria using PCL-5 (PTSD Checklist for DSM-5)
data. Functions identify optimal subsets of PCL-5 items that maintain
diagnostic accuracy while reducing assessment burden. Includes tools for
both hierarchical (cluster-based) and non-hierarchical symptom combinations,
calculation of diagnostic metrics, and comparison with standard DSM-5
criteria. Model validation is conducted using holdout and cross-validation
methods to assess robustness and generalizability of the results. For more
details see Weidmann et al. (2025) <doi:10.31219/osf.io/6rk72_v1>.
