Stage 1b Study of ACT-PT vs. FFS
This study involves a randomized clinical trial study of 50 Veteran smokers with PTSD and tobacco dependence randomized to one of two different types of psychosocial treatment: 10 individual sessions of ACT-PT (n= 25) versus 10 individual sessions of the American Lung Association's Freedom From Smoking Program \[FFS\] (n=25). This study has two primary aims: 1) Evaluate the relative feasibility and acceptability of the two interventions (including ease of recruitment, randomization proportion, staff and Veteran acceptance of the treatment, retention rates, treatment adherence, fidelity, ease of the assessment process), and 2) Evaluate the preliminary efficacy of ACT-PT vs. FFS with the primary outcomes of tobacco use, PTSD symptoms, health-related quality of life, and functional impairment. Acceptance and Commitment Therapy for PTSD and Tobacco Use: ACT-PT is an acceptance and mindfulness-based smoking cessation treatment for Veterans with PTSD and tobacco dependence.
Freedom From Smoking
The American Lung Association's Freedom from Smoking program (FFS) is a commonly used smoking cessation intervention that is used in community treatment programs.

Timeframe: Change in PTSD symptoms from Baseline to End of Treatment (12 week outcome)

The PCL-5 is a brief, self-report symptom checklist that assesses the 20 symptoms of PTSD outlined in the Diagnostic and Statistical Manual-5 (DSM-5) and was designed to assess symptom changes during and after treatment in addition to screening. The PCL has shown satisfactory temporal stability, internal consistency, test-retest reliability, and convergent validity. The minimum value of the PCL-5 is 0, and the maximum value is 80. Higher scores indicate more severe PTSD symptoms.

Timeframe: Change in Functional Impairment from Baseline to End of Treatment (12 week outcome)

The Short Form 36 Health Survey (SF-36) is a 36-item self-report measure of current physical, mental health, and social functioning. We are reporting the mental health functioning outcome. A total score was computed by summing and transforming the five-item scores into a score between 0 (lowest mental health) and 100 (highest mental health). Lower scores indicate more severe functioning related to mental health problems.

Timeframe: Change in Quality of Life from Baseline to from Baseline to End of Treatment (12 week outcome)

The Quality of Life Enjoyment and Satisfaction Questionnaire is a commonly used self-report measure to assess quality of life in several domains: general activities, physical health, subjective feelings, leisure time activities, social relationships, work, and household duties. Higher scores indicate better enjoyment and satisfaction with life. The scoring of the Quality of Life Enjoyment and Satisfaction Questionnaire involves summing the first 14 items to yield a total score. The total score ranges from 14 to 70 and is expressed as a percentage based on the maximum total score of the items completed (0-100).
