Study Summary
Smoking is the leading preventable cause of death and disease in the United States. Although most smokers report that they would like to quit smoking at some point in the future, only 20% are ready to quit within the next 30 days. Importantly, studies have indicated that interventions can increase motivation and/or readiness for cessation among smokers who are not yet ready to quit and these types of intervention can increase smoking cessation attempts. Smartphone apps that offer daily information about the benefits of quitting and motivational/supportive messages that aim to increase cessation self-efficacy may increase the likelihood of initiating a smoking cessation attempt. Previous research has indicated that smoking cessation smartphone applications are feasible and well-liked by smokers who are already committed to quitting smoking. However, there are no empirically supported smartphone apps that provide dynamic smoking cessation content that is automatically matched to a smoker's current readiness to quit. This type of dynamically tailored intervention could overcome many of the barriers that have hampered the widespread use of traditional empirically supported smoking cessation treatments. The current pilot study (N=150) is a 3-armed randomized controlled smoking cessation induction trial that will determine the initial utility of a novel smartphone based intervention compared with an attention control group among smokers who are not yet ready to quit. The two intervention groups (Group 1: Phoenix App Only; Group 2: Phoenix App + Nicotine Replacement Therapy \[NRT\]) will receive targeted smoking cessation messaging that is matched to a participant's readiness to quit, while the attention control group (i.e., Factoid) will receive messages that are not related to smoking cessation.
