The aims of this pilot protocol are to test the adherence, acceptability, user satisfaction, and preliminary efficacy of a smartphone mobile health app, Free4Good, which incorporates skills training in positive psychology vs. a relaxation app, Breathe2Relax (control condition), in a small randomized controlled trial of smokers (N = 24). Adherence will be measured directly through app usage data. Acceptability and user satisfaction will be measured via specific items included on a User Satisfaction Questionnaire. Efficacy outcomes include evidence of increased engagement in positive psychology-related quitting strategies (measured by the Quitting Strategies Questionnaire) and smoking abstinence.
Exploratory analyses including covariates such as nicotine dependence, mood, and depressive symptoms may be examined as appropriate, as these measures have been shown to predict abstinence outcomes in a variety of studies.1-4 Changes in mood and/or depressive symptoms may also be characterized
