Figure 1. Recursive Partitioning Decision Tree for Baseline PTSD Screening.

Figure 1

Anxiety was measured using the Hospital Anxiety and Depression Scale (HADS; possible scores 0-21); bond with patient was measured using the Intimate Bond Measure (IBM; possible scores 0-72); and mindfulness was measured using the Cognitive and Affective Mindfulness Scale-Revised (CAMS-R; possible scores 12-48). Further details on these measures and corresponding references are provided in Supplementary Materials. Cut-offs shown for each variable were determined empirically through recursive partitioning for optimal classification of baseline PTSD.
