The specific aims of the project are to develop and test a Spanish language, mobile app for smoking cessation called Impacto.
A total of 38 Spanish-speaking, Latinx smokers with high anxiety sensitivity (AS) will be recruited for this project. Eight (8) participants will complete user interviews in Spanish and thirty (30) participants will participate in a randomized controlled trial (RCT) for smoking cessation. Participants will be randomized to receive either the Impacto mobile app or a generic, Spanish language, smoking cessation, mobile app control (Dejar de Fumar Asistente).
