Primary outcomePrimary: Ease-of-use and Helpfulness of the App — 2.39; 2.36; 2.42; 2.39 units on a scale
Summary
The overall goal of this pilot study is to solicit feedback from nondaily smokers looking for smoking cessation support online (n=90) about Version 2 of a smartphone app investigators designed to support smoking cessation, and to test if within-person theorized mechanisms of change are occurring as participants undergo the app-assisted quit attempt. Data sources will be passively collected smartphone app usage data, surveys and, in a sub-sample (n=20), online video-conference user feedback sessions. Results will be used to guide the design of Version 3.0 of the "Smiling Instead of Smoking" (SiS) smartphone app. Specifically, the aims of this study are to:
1. Assess ease-of-use and helpfulness of the app, as rated by app users 6 weeks after their chosen smoking cessation date
2. Test if within-person changes occur in theorized mechanisms of behavior change as nondaily smokers undergo a SiS app assisted quit attempt
3. Identify app features in need of improvement, as identified by passively recorded app usage patterns, REDCap open-ended survey items, and, in a sub-sample, user feedback sessions (n=20)
