Figures 1a-1d. AUCs of all short-form PCL-5 scales in the training sample (n=8,917).
Short-form PCL scales have between one and eight items and were created using three statistical methods (RiskSLIM, stepwise regression, and factor analysis), including both weighted and unweighted versions of stepwise and factor analysis. Each scale was used to predict dichotomous PTSD outcomes (shown in each panel, a-d), which were assigned based on full PCL-5 responses using four diagnostic thresholds (DSM-5 Criteria B-E, and total PCL-5 scores >= 28, >=32, and >=38).
