About
Tobacco use among US Veterans poses significant health problems and challenges to their overall well-being. The aim of this project is to evaluate the effectiveness of a program called Contingency Management (CM) in helping Veterans quit smoking during lung cancer screening or cancer care at VA clinics. CM is a behavioral treatment that uses rewards to encourage smoking cessation when verified through biological testing. In the first year, the researchers will develop a mobile CM protocol based on feedback from Veterans and healthcare staff through focus groups. In the second year, they will conduct a pilot study to test the feasibility of the mobile CM program along with counseling and medication for 20 Veterans over a five-week period. The success of the pilot study will determine whether to proceed with a larger randomized controlled trial (RCT) in years three to six, comparing the efficacy of mobile CM with standard treatment. The project will take place at SFVA.
Full description
Smoking at the time of lung cancer screening (LCS) or cancer diagnosis is associated with treatment failure, shortened lifespan, and diminished quality of life. Beyond the increased morbidity and mortality, smoking after a cancer diagnosis is associated with an estimated $3.4 billion in healthcare costs. Despite these risks, the VA does not routinely integrate smoking cessation treatment into LCS screening or cancer care, and quit rates are low.
Contingency Management (C) is a behavioral therapy approach that reinforces desired behaviors, such as smoking cessation, through the provision of tangible rewards or incentives. The goal of this Proof of Concept and Clinical Trial project is to evaluate the acceptability, feasibility, and efficacy of Contingency Management (CM) for smoking cessation among Veterans in lung cancer screening (LCS) or cancer care in Veterans Affairs (VA) clinics.
Research indicates that CM must be tailored to the clinical population and context. This staged investigation will occur in three phases. First, the investigators will conduct Focus Groups, to iteratively develop an acceptable mobile CM protocol using qualitative feedback from Veterans in VA patients in LCS or in cancer care and LCS and oncology staff. Afterward, the investigators will conduct a Pilot Study to examine the feasibility of mobile smoking cessation CM with for VA patients in LCS or in cancer care. In a single arm study, Veterans in VA LCS or cancer care will receive mobile CM plus behavioral counseling and cessation medication over 5 weeks. If successful, the investigators will conduct a Randomized Controlled Trial (RCT) to assess efficacy of mobile CM compared with treatment as usual (TAU). Veterans diagnosed with cancer or in LCS will be randomized to receive a 5-week CM condition (CM plus behavioral counseling) or TAU (referral to VA Tobacco Cessation Clinic and VA quitline). Both groups will receive pharmacotherapy.
The primary aims of this study are to develop an acceptable mobile CM protocol through qualitative feedback from Veterans and VA staff, to examine the feasibility of mobile smoking cessation CM among Veterans in LCS or cancer care through a pilot study, and to assess the efficacy of mobile CM compared to treatment as usual through a randomized controlled trial among Veterans diagnosed with cancer or in LCS.

Inclusion criteria
In order to be eligible to participate in this study, an individual must meet all of the following criteria:
- Human Subjects Involvement and Characteristics: This Proof of Concept and Clinical Trial has three stages. The Proof-of-Concept Phase (Years 1-2) includes a Focus Group phase (Year 1) in which the investigators will recruit both Veterans and non-Veterans (VA clinical staff); and a Pilot Study (Year 2) in which the investigators will recruit Veterans in LCS or cancer treatment at San Francisco VA Healthcare System (SFVAHCS). If the Pilot Study is successful, the investigators will recruit Veterans in LCS or cancer treatment for the RCT (Years 3-6).
- Focus Groups: For Focus Groups (Year 1), the investigators will recruit both Veterans and VA clinical staff at SFVAHCS.
Veterans:
- Age 18 years or older
- Veteran eligible for VA healthcare
- English-speaking
- Received SFVAHCS cancer monitoring or treatment or LCS within the past 24 months
- Active cigarette smoking within the past 24 months
- Have access to Wi-Fi and a device that supports audio and video communication
VA Clinical Staff:
- Current member of clinical staff at the SFVAHCS
- Have participated in the care of at least 5 VA cancer or LCS patients in the past 6 months
Pilot Feasibility Study (Year 2) and Randomized Controlled Trial
Inclusion criteria:
- Age 18 years or older
- Veteran currently receiving medical care at SFVAHCS (at least one clinical visit same calendar year for cancer)
- English-speaking
- Current, active (same calendar year) enrollment in VA LCS, or current (same calendar year) diagnosis of cancer documented in the VA medical record, confirmed through medical record review
- Current (past 30 days) cigarette smoking a minimum of 1 cigarette per day (average), assessed by Timeline Followback (TLFB)92, 99-101
- Open to receiving smoking cessation interventions
Exclusion criteria
Focus Groups: For Focus Groups (Year 1), the investigators will recruit both Veterans and VA clinical staff at SFVAHCS.
Veterans:
Exclusion criteria: Assessed by Co-PIs' medical record review:
- Current severe, untreated mental illness (i.e., psychosis, bipolar disorder, and/or substance use disorder (SUD)) and/or
- Current (past 30 days) active suicidal/homicidal ideation or severe behavioral instability that would prevent participation
- Never smokers or quit smoking for longer than 36 months prior to consent (4) no access to Wi-Fi or devices that support audio and video communication
VA Clinical Staff:
Exclusion Criteria:
- Unable to commit 1.5 hours (60 min focus group and self-report questionnaires)
Pilot Feasibility Study (Year 2) and Randomized Controlled Trial
Exclusion Criteria:
- An individual who meets any of the following criteria will be excluded from participation in this study:
- Evaluated by investigative team medical record review and clinical assessment:
- Psychotic disorders, bipolar disorder, neurocognitive disorder, substance use disorders, or other psychiatric or medical conditions judged by the PI to be unstable in the past 30 days, based on screening results and/or medical record review, including conditions for which large sums of money would be potentially destabilizing
- Untreated, current, active problem gambling, assessed by medical record diagnosis and/ or Problem Gambling Severity Index (PGSI) score 8
- Metastatic cancer or enrollment in end of life/ palliative care
- Unable to commit to time commitment required for participation
- Currently pregnant or planning to become pregnant during the study (people of childbearing potential ages 18-55 who are pregnant or state that they plan to become pregnant during the study)
- A suicide attempt or suicidal ideation with intent in the 30 days prior to enrollment
- Concurrent enrollment in a tobacco cessation clinical trial
