Mobile App Program to Help Young Adults Quit Tobacco Using Two Support Approaches

What this Trial Is About

Tobacco use is a leading cause of preventable cancer deaths, with about one in five young adults using commercial nicotine and tobacco products. This study evaluates two versions of a mobile health intervention called Living Free from Tobacco LiFT designed to support cessation among young adults aged 18 to 30. The goal is to engage this population, who are less likely to participate in traditional treatments, by providing a novel, accessible approach to quitting tobacco. Participants are assigned to one of three phases. The first phase involves user testing interviews to refine the LiFT app prototypes. In the pilot trial phase, participants are randomly assigned to use either LiFT A, which incorporates acceptance and commitment therapy with interactive games and exercises, or LiFT B, which offers educational content and health videos. Both interventions last 3 months and include text messages 2-3 times per week. The final phase is a post-pilot diary study where participants use the app and complete daily usability and satisfaction surveys for about one week. Throughout the study, participants complete surveys, usability assessments, and interviews to provide feedback and measure satisfaction, program usefulness, and engagement with the app. Researchers also assess tobacco cessation outcomes, including self-reported and biochemically confirmed abstinence at 3 months. The study is conducted entirely in English and requires participants to own a compatible smartphone with internet access and use text messaging and email. The total participation time varies by study phase but includes up to 3 months for the pilot phase and about one week for the diary study.
