Brief summary
The specific aims of the project are to develop and test a Spanish language, mobile app for smoking cessation called Impacto.
Detailed description
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).
Interventions
BEHAVIORALImpacto (Mobile App)
This is the mobile app to be developed and evaluated in this project. It is designed for Spanish-speaking, Latinx smokers with high anxiety sensitivity and will be built for the Android platform. The app will include components to address and remediate anxiety sensitivity, as well as having smoking cessation components.
BEHAVIORALDejar de Fumar Asistente (Mobile App)
Dejar de Fumar Asistente (English version called: Quit Tracker: Stop Smoking) is a popular, free third party mobile application aimed at helping smokers quit smoking. This is the mobile app that will serve as the control condition in evaluating the efficacy of Impacto. This mobile app is well established as a smoking cessation app for Spanish-speaking, Latinx smokers. The app includes smoking cessation components but does not have a specific emphasis on anxiety sensitivity.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 7-Day Point Prevalence Smoking Abstinence | End of treatment (Week 8) | Self-reported 7-day point prevalence smoking status. Verification via carbon monoxide at end of treatment (10 weeks). |
| Change in Smoking Rate (# cigarettes per day) | Baseline and Weeks 2, 4, 6, and end of treatment (Week 8) | We will assess the number of cigarettes smoking at each time point. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Anxiety Sensitivity | Baseline and Weeks 2, 4, 6, and end of treatment (Week 8) | Anxiety sensitivity will be assessed using the Anxiety Sensitivity Index-3 (ASI-3). |
| Change in Mood and Anxiety Symptoms | Baseline and Weeks 2, 4, 6, and end of treatment (Week 8) | The Mood and Anxiety Symptom Questionnaire (MASQ) is well-validated measure and will be used to assess anxiety/depressive symptoms. |
| Daily Adherence to Use of Impacto Mobile App (Impacto Condition Only) | Daily over the course of the 8 weeks of participant study involvement | We will access these data via the back end of the Impacto server to evaluate whether the criterion of 75% daily adherence (i.e., app use on 75% of all possible days) has been achieved. |
| User Satisfaction with the Impacto Mobile App (Impacto Condition Only) Condition Only) | Weeks 2, 4, 6, and 8 | User satisfaction ratings scored on a 1-9 Likert scale with higher scores indicating better user satisfaction. |
