Note. Urges were rated on a 0 to 5 scale. Measures to assess pre-post session urges were added to the assessment battery after the study started and data are therefore available for only a subset of the therapy sessions (DBT sessions: n = 209/404, PTSD Protocol sessions: n = 49/99). Pre-post exposure urges were assessed throughout the study.
