Note. N = 121, collaborative care intervention n = 60, usual care control n = 61. CC = collaborative care intervention; UC = usual care control; PTSD = posttraumatic stress disorder; PCL-C = PTSD Checklist-Civilian version; PHQ-9 = Patient Health Questionnaire.

Adjusted for age, gender, injury severity score, and race.

Adjusted for baseline PCL-C score, age, gender, injury severity score, and race.

t statistic from mixed model regression yielded p ≤ .05.
