The overall goal of the study is to evaluate how motivation and readiness for change are influenced in the context of a smoking cessation attempt. A total of 60 adult (i.e. age 18-55) smokers (N=40 with ADHD; N=20 without ADHD) who are interested in quitting will be enrolled into a 3-arm trial allocated as follows. Twenty of the ADHD smokers and the 20 non-ADHD smokers will be assigned to a traditional 8-week contingency management intervention in which monetary payments will be made contingent upon biologically verified evidence of smoking abstinence. The 20 additional ADHD smokers will be assigned to a treatment-as-usual condition (nicotine replacement; supportive counseling). During the treatment phase, subjects will be required to answer questions 4x/week in their daily lives via an EMA (Ecological Momentary Assessment). Specific Aim 1: To assess motivation to quit smoking and readiness for change prior to a quit attempt in treatment seeking ADHD and non-ADHD smokers. Hypothesis 1a: The investigators hypothesize that prior to a quit attempt, smokers with ADHD will exhibit significantly lower levels of intrinsic motivation to quit, and equal or higher levels of extrinsic motivation to quit compared to smokers without ADHD. Hypothesis 1b: The investigators hypothesize that smokers with ADHD will exhibit relatively less readiness for change than smokers without ADHD. Specific Aim 2: To assess how baseline levels of motivation to quit and readiness for change are influenced during a quit attempt as a function of both ADHD status and treatment modality. Hypothesis 2a. The investigators hypothesize that the CM intervention will result in relatively greater change in extrinsic motivation to quit versus intrinsic motivation to quit, and that this effect will be more pronounced among ADHD smokers. Hypothesis 2b: The investigators hypothesize that overall motivation to quit (intrinsic and extrinsic) and readiness for change will be significantly influenced by the CM intervention versus treatment as usual among ADHD smokers. Exploratory Aim 1: To assess the relative efficacy of a CM intervention versus treatment as usual in smokers with ADHD. The investigators hypothesize that CM will be more effective for promoting short-term (4-8 weeks) smoking abstinence, as well as for promoting longer-term (3-6 months) smoking cessation. Exploratory Aim 2: To assess the associations among smoking withdrawal/craving, affect, ADHD symptoms, and motivation to quit/readiness for change. The investigators hypothesize that higher levels of motivation and readiness for change will be associated with lower levels of self-reported withdrawal, craving, and negative affect.

Primary | Change in motivation to quit smoking, as measured by the Readiness to Change Questionnaire | During the treatment period, participants will answer at least 4 times weekly, questionnaires to assess motivation for behavior change, autonomy, and interest in quitting. The Readiness to Change Questionnaire (RCQ) is a measure designed to assess attitudes toward quitting smoking. | Baseline to 9 weeks | |
Primary | Change in motivation to quit smoking, as measured by the Treatment Self-Regulation Questionnaire | During the treatment period, participants will answer at least 4 times weekly, questionnaires to assess motivation for behavior change, autonomy, and interest in quitting. The Treatment Self-Regulation Questionnaire measures autonomous motivation. | Baseline to 9 weeks | |
Primary | Change in motivation to quit smoking, as measured by the Perceived Competence Scale for Cessation | During the treatment period, participants will answer at least 4 times weekly, questionnaires to assess motivation for behavior change, autonomy, and interest in quitting. The Perceived Competence Scale for Cessation measures perceived competence to quit. | Baseline to 9 weeks | |
Primary | Change in motivation to quit smoking, as measured by the Reasons For Quitting questionnaire | During the treatment period, participants will answer at least 4 times weekly, questionnaires to assess motivation for behavior change, autonomy, and interest in quitting. The Reasons For Quitting questionnaire measures relative levels of intrinsic versus extrinsic motivation to quit smoking. | Baseline to 9 weeks | |

Primary | Comparison of populations in motivation to quit on the Reasons for Quitting Questionnaire | The study team will compare the change in scores for extrinsic and intrinsic motivation to quit on the Reasons for Quitting Questionnaire in the ADHD and non-ADHD groups assigned to receive CM. | Baseline to 9 weeks | |
Secondary | Change in smoking behavior in ADHD population | This outcome is based both upon the treatment period and follow-up visits at 3 and 6 months. CM is proposed to be a potential more effective treatment in an ADHD population in the short and longer term, in comparison to treatment as usual. This will be measured by urine cotinine level and residual Carbon Monoxides levels from samples provided by participants. | Baseline, 3 months, 6 months | |
Secondary | Decreasing effects of quitting smoking. | This outcome assesses overall whether increased motivation and readiness for behavior change (i.e. quit smoking), potentially associated CM, will decrease negative aspects of quitting. These include smoking withdrawal/craving, affect, and impact on ADHD symptoms. | Baseline, 3 months, 6 months |
