Brief Summary

Smoking is the leading cause of preventable illness, disability, and death in the United States. The rate of smoking is disproportionately higher among Veterans with posttraumatic stress disorder (PTSD). Unfortunately, smoking cessation efforts that are effective in the general population have shown limited effectiveness in smokers with PTSD. The high smoking rate and difficulty with achieving abstinence indicate a critical need to develop effective interventions for Veterans who smoke and have PTSD. The investigators' data indicate that negative emotions and trauma reminders are associated with relapse for smokers with PTSD. In this context, an ideal strategy may be to combine evidence-based PTSD treatment with intensive smoking cessation treatment to maximize quit rates. Cognitive processing therapy (CPT) is a well-established evidence-based treatment for PTSD. The investigators have successfully developed a treatment manual that combines CPT with cognitive-behavioral counseling for smoking cessation. Contingency management (CM) is another intensive behavioral treatment that has been shown to help with reducing smoking. CM provides positive reinforcers such as money to individuals misusing substances contingent upon abstinence from use. The primary goal of this study is to evaluate the efficacy of a treatment that combines CM with cognitive-behavioral smoking cessation counseling, smoking cessation medication, and CPT. Proposed is a randomized, two-arm clinical trial in which 120 Veteran smokers with PTSD will be randomized to either: 1) COGNITIVE PROCESSING THERAPY with SMOKING ABSTINENCE REINFORCEMENT THERAPY (CPT-SMART) or 2) COMBINED CONTACT CONTROL, an intervention identical to CPT-SMART in PTSD and smoking treatment, except for using payment that is not contingent on abstinence. Specific aims include: AIM 1) To evaluate the efficacy of CPT-SMART on rates of short- and long-term abstinence from cigarettes; AIM 2) To evaluate the impact of CPT-SMART on treatment engagement and utilization; and an EXPLORATORY AIM) To explore mechanisms of CPT-SMART on long-term smoking abstinence. The positive public health impact of reducing smoking among Veterans with PTSD could be enormous as it would prevent significant smoking-related morbidity and mortality.

  • Number of participants whose self-report of 30 day point prevalence abstinence from smoking is bioverified

    6 month follow-up

  • Number of participants whose self-report of 7 day point prevalence abstinence from smoking is bioverified

    4 month follow-up

  • Number of participants whose self-report of 30 day point prevalence abstinence from smoking is bioverified

    4 month follow-up

  • Number of participants who self-report prolonged abstinence

Study Arms (2)

CPT-SMART

EXPERIMENTAL

COGNITIVE PROCESSING THERAPY with SMOKING ABSTINENCE REINFORCEMENT THERAPY (CPT-SMART) - an intervention that combines evidence-based PTSD treatment with guideline-concordant cognitive-behavioral smoking cessation counseling, bupropion, and intensive behavioral therapy through CM.

Behavioral: Smoking Cessation Cognitive Behavioral Therapy (CBT)Drug: BupropionBehavioral: Cognitive Processing TherapyBehavioral: Smoking Abstinence Reinforcement Therapy

Combined Contact Yoked Control

ACTIVE COMPARATOR

COMBINED CONTACT YOKED CONTROL (CCYC) - an intervention that is identical to CPT-SMART for PTSD and smoking treatment, except for using non-contingent payment (i.e., yoked CM) to control for compensation and monitoring.

Behavioral: Smoking Cessation Cognitive Behavioral Therapy (CBT)Drug: BupropionBehavioral: Cognitive Processing TherapyBehavioral: Yoked Contingency Management

Interventions

12 sessions of cognitive behavioral therapy for smoking cessation, designed to help participants prepare for quitting smoking, make a quit attempt, and stay quit from smoking.

Also known as: CBT
CPT-SMARTCombined Contact Yoked Control

All medically eligible participants will be prescribed bupropion to begin 7 days before the quit date and continued through 12 weeks post-quit. Participants will be scheduled to begin at 150mg/day of bupropion for at least 3 days before titrating up to 300mg/day dose of bupropion.

Also known as: Zyban
CPT-SMARTCombined Contact Yoked Control

12 sessions of CPT, which is a well-established trauma-focused psychotherapy for PTSD that has demonstrated efficacy and effectiveness in Veterans.

Also known as: CPT
CPT-SMARTCombined Contact Yoked Control

Monetary reinforcement for smoking abstinence that is bioverified by breath carbon monoxide and saliva samples.

Also known as: SMART
CPT-SMART

Participants in the yoked control will receive the monetary reinforcement of their yoked participant regardless of smoking abstinence or session attendance.

Also known as: Control CM
Combined Contact Yoked Control
