This project will test the effectiveness of a stepped-care talk therapy model for patients with PTSD and Hazardous Alcohol use (HAU). Specifically, the researchers are testing whether beginning with one type of therapy is better than beginning with another type of therapy, and whether moving to a different therapy after five sessions is more helpful than staying with the same therapy, depending on how well it is working.
In the case of uneven dropout across interventions, the research team will recruit additional patients until target sample is reached.

Phone follow-up, which will occur 2- and 4-weeks after session 5.
PC-TIME consists of five 30-minute sessions, with daily homework assigned between sessions.

Change in PTSD symptom severity (as measured by the PTSD Symptom Checklist for DSM-5)
The study team is planning on measuring change at each timepoint. Baseline to visit 5, baseline to visit 10, and visit 5 to visit 10. The checklist is 20 items and each item has a scale of 0 to 4 (total range of 0-80). Higher scores indicate greater symptom severity.
Time frame: Baseline, Session 5, Session 10 (Approximately week 1, 8, 15)
Change in alcohol use (as measured by the Timeline Follow Back)
The study team is planning on measuring change at each timepoint. Baseline to visit 5, baseline to visit 10, and visit 5 to visit 10.
