About this study
Official title: Impacto 2.0: Addressing Disparities in Smoking Cessation Access and Outcomes for Hispanic Adults Who Smoke in Texas
This is a preliminary efficacy trial that will examine whether Impacto 2.0 produces higher rates of biochemically verified smoking abstinence among Hispanic adults across Texas compared to the NCI quitSTART app. The primary objective is to evaluate the preliminary efficacy of Impacto 2.0 in reducing smoking, tobacco withdrawal, and craving. One hundred Hispanic adults who smoke will be recruited across Texas and followed remotely over an 8-week intervention period with a 3-month post-quit follow-up.
Read the detailed description
Impacto 2.0 is a culturally adapted, bilingual (English and Spanish) smartphone-based smoking cessation intervention designed for Hispanic adults who smoke and have elevated anxiety sensitivity. The intervention includes smoking cessation content, psychoeducation, coping skills, and exercises designed to reduce anxiety sensitivity.
Eligible participants will be randomly assigned in a 1:1 ratio to receive either Impacto 2.0 or the National Cancer Institute's quitSTART app. Participants in both conditions will receive study-provided nicotine replacement therapy and will use their assigned mobile application during an 8-week treatment period.
Participants will complete 4 weeks of pre-quit app engagement, with their quit day and nicotine replacement therapy start scheduled at Week 4, followed by 4 weeks of post-quit treatment. Study assessments will be completed at baseline, Week 4, Week 8, and Week 16. Smoking status will be assessed through self-report and remote biochemical verification using the CoVita iCOquit Smokerlyzer.
The primary outcome is biochemically verified 7-day point-prevalence smoking abstinence at Week 8. Secondary outcomes include smoking abstinence at Week 16 and changes in anxiety sensitivity, tobacco withdrawal, and craving.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Impacto 2.0Behavioural
A culturally adapted, bilingual smartphone-based smoking cessation intervention that provides psychoeducation targeting anxiety sensitivity reduction. The app includes four lessons per week across the 8-week intervention period and exercises targeting anxiety sensitivity.
quitSTARTBehavioural
The National Cancer Institute's quitSTART smartphone smoking cessation application. The app provides tools to help users understand smoking patterns, track smoking habits and urges, and manage cravings.
| Study group | Role | What they receive |
|---|---|---|
| Impacto 2.0 | Experimental | Participants will use the Impacto 2.0 smartphone application for 8 weeks. Receives: Behavioral: Impacto 2.0 |
| quitSTART | Active comparator | Participants will use the National Cancer Institute's quitSTART smartphone application for 8 weeks. Receives: Behavioral: quitSTART |
What is being measured
The primary outcome is the main question the study is designed to answer.
Biochemically Verified 7-Day Point Prevalence Smoking Abstinence
Smoking abstinence will be assessed using self-reported 7-day point prevalence abstinence and biochemically verified using the CoVita iCOquit Smokerlyzer. An expired carbon monoxide level <7 ppm will indicate abstinence.
Measured: Week 8
Secondary outcomes (4)
Biochemically Verified 7-Day Point Prevalence Smoking Abstinence
Smoking abstinence will be assessed using self-reported 7-day point prevalence abstinence and biochemically verified using the CoVita iCOquit Smokerlyzer. An expired carbon monoxide level <7 ppm will indicate abstinence.
Measured: Week 16
Tobacco Withdrawal
Tobacco withdrawal will be assessed using the Minnesota Nicotine Withdrawal Scale (MNWS).
Measured: Baseline, Week 4, Week 8, and Week 16
Tobacco Craving
Tobacco craving will be assessed using the Questionnaire of Smoking Urges-Brief (QSU-B).
Measured: Baseline, Week 4, Week 8, and Week 16
Anxiety Sensitivity
Anxiety sensitivity will be assessed using the Short Scale Anxiety Sensitivity Index (SSASI).
Measured: Baseline, Week 4, Week 8, and Week 16
