简要总结
The purpose of this study is to examine whether tobacco affects recovery from PTSD. There are 3 goals of the study; (1) to test if quitting tobacco prior to PTSD treatment affects treatment success, (2) to test how PTSD symptoms change in those who have quit tobacco compared to those who continue to use and (3) to explore how tobacco use and tobacco withdrawal symptoms change during PTSD treatment.
详细描述
The proposed research aims to examine the effect of tobacco on PTSD symptoms and PTSD recovery as well as the effect of PTSD recovery on tobacco use. This study has 3 aims: (1) to evaluate whether tobacco use interferes with recovery from PTSD during empirically based, trauma focused PTSD treatment. (2) To gather preliminary data about whether tobacco use alleviates PTSD symptoms among continued tobacco users vs. recent quitters. (3) To explore the impact of recovery from PTSD treatment on tobacco use quantity and frequency, tobacco withdrawal symptoms, and craving for tobacco. To test these aims, the investigators propose a randomized two group design where 75 participants are assigned to receive either tobacco treatment (Contingency Management plus Cognitive Behavioral Therapy) or control treatment (Health Education) before completing Cognitive Processing Therapy (CPT) for PTSD. Study outcome variables will be PTSD symptom severity following CPT, PTSD symptom severity during tobacco cessation treatment, and tobacco use and tobacco withdrawal during CPT.
