- Brief Summary
The current study tests a response inhibition retraining program, implemented on a mobile device, as a mechanism to increase relapse prevention during a smoking cessation attempt. Study participants (n = 150) are randomly assigned to a control, benign, or intervention condition. They complete 2 weeks of response inhibition retraining, and then engage in a cessation attempt. It is hypothesized that individuals who receive the intervention will have a decreased likelihood of relapse following the cessation attempt. In addition, it is hypothesized that this is due to decreases in implicit smoking motivation as a function of the response inhibition training.
- Detailed Description
Smoking is the leading preventable cause of death and disease in the U.S. Each year approximately 30% of smokers try to quit, with the vast majority of attempts (\~90%) ending in relapse. This is complicated by treatment barriers related to cost and accessibility. Identifying cost effective ways to aide in cessation success, which can be widely disseminated, remains vitally important. According to the dual-process model of substance use, addiction develops via an imbalance between effortful control and automatic psychological processes. The affective processing model suggests that during withdrawal, automatic psychological processes increase implicit drug seeking motivation. Implicit motivation is hypothesized as the underlying mechanism through which automatic psychological processes exert control over behavior. Research suggests that behavioral impulse control may attenuate the association between implicit motivation and substance use. Response inhibition, one form of behavioral impulse control, is the ability to inhibit behavioral responses to salient approach cues. Smokers tend to have less behavioral impulse control. In addition, poor behavioral impulse control makes individuals more vulnerable to various risk factors associated with relapse (e.g., positive expectancies, higher craving during abstinence, etc.). Improving smoking relevant behavioral impulse control may affect multiple indices of relapse. Research in cognitive retraining has shown that response inhibition can be modified through training. Recently this has been extended to training using mobile devices. The development of mobile interventions which specifically target underlying mechanisms of addiction may provide a novel adjunct to current cessation programs. The current proposal builds on previous research by implementing a response inhibition training paradigm in the context of a cessation trial. It is hypothesized that this task will reduce the likelihood of relapse following a quit attempt. Furthermore, it is hypothesized that training effects will operate via decreases in implicit motivation and global craving. If successful, the current study will provide evidence for a relapse prevention tool that can (1) increase overall cessation success and (2) be widely and easily dispersed.

- Arm && Interventions
Group Intervention Description Response Inhibition Training: B Response Inhibition Training In the active comparator condition, 20% of responses are no-go trials, with no-go responses spread evenly across the various images. Response Inhibition Training: A Response Inhibition Training In the experimental condition, 20% of responses are no-go, with the majority of no-go responses paired with smoking images.
- Primary Outcome Measures
Name Time Method Smoking relapse 6 months A relapse is defined as a resumption of smoking behavior, following a cessation attempt, with the acknowledgement that the study participant is no longer trying to quit smoking. Abstinence is verified with Cotinine.
