Outcomes

Primary Outcomes

Posttraumatic Stress Disorder (PTSD) Symptom Scale - Interview (PSS-I-IV)

The PSS-I-IV is a clinician-rated interview that evaluates PTSD symptoms on a frequency/severity scale corresponding to the DSM-IV symptom criteria. The measure has a total score range from 0 to 51, with higher scores indicating more severe PTSD symptoms.

Time frame: Week 0 (Pretreatment), Week 24 (Posttreatment), Week 52 (Follow-up)

Drinking Timeline Follow-back Interview (TFBI)

The TFBI is an interview that utilizes a calendar method to assess when and how much alcohol was consumed by the participant. At Week 0 (Pretreatment), Week 24 (Posttreatment), and Week 52 (Follow-up), alcohol consumed in the past 90 days was assessed. This measure was then used to calculate the percentage of days drinking in the past 90 days at each time point. Higher scores for percentage of days drinking indicate worse drinking outcomes.

Time frame: Week 0 (Pretreatment), Week 24 (Posttreatment), Week 52 (Follow-up)

Secondary Outcomes

Penn Alcohol Cravings Scale

The Penn Alcohol Craving Scale is a 5-item self-report measure. It assesses alcohol craving during the prior week. Total scores on this measure range from 0 to 30, with higher scores indicating a higher level of craving.

Time frame: Week 0 (Pretreatment), Week 24 (Posttreatment), Week 52 (Follow-up)
