Objectives: The study is designed to determine if adding motivational counseling and care management using the PTSD Health Buddy to usual care improves smoking quit rates of veterans with PTSD. Specific Aims are to compare: 1) self-reported quit attempts, progression through the stages of change, and quit rates, 2) patient perception of care coordination, and 3) changes in PTSD symptoms in veteran smokers with PTSD who receive a nurse-driven telephonic motivational counseling intervention triggered by responses to stage-based smoking cessation questions in addition to usual care to those who receive usual care only.
