A Novel Mobile Health Intervention for Improving Tobacco Cessation Among Young Adults

2 september 2026 uppdaterad av: Fred Hutchinson Cancer Center

Development and Pilot Evaluation of a Novel Mobile Health Intervention for Young Adult Tobacco Cessation

Tobacco use is the leading cause of preventable cancer deaths. Among young adults, approximately 1 in 5 use commercial nicotine and tobacco products, putting them at risk of developing nicotine addiction and long-term health effects from exposure to toxicants. Innovative approaches are needed to engage young adults in treatment, as they are less engaged in traditional treatment.

This clinical trial compares two versions of a mobile health intervention called Living Free from Tobacco (LiFT), designed to support nicotine and tobacco cessation among young adults. Both versions of the app are designed to motivate and support young adults to stop using nicotine and tobacco, regardless of current readiness to quit. Version A of the LiFT app (LiFT A) focuses on increasing psychological flexibility to support cessation, while Version B (LiFT B) provides educational content and resources related to tobacco use and cessation. Both versions of the program are delivered through a smartphone application and include accompanying text messages.

Studieöversikt

Detaljerad beskrivning

OUTLINE: Participants are assigned to 1 of 3 phases.

USER-CENTERED DESIGN AND PROGRAM DEVELOPMENT PHASE (Objective 1): Participants attend user testing interviews where they interact with LiFT application (app) prototypes and provide feedback through think-aloud methods to support refinement of the intervention content and features.

PILOT TRIAL PHASE (Objective 2): Participants are randomized to 1 of 2 arms.

  • ARM I: Participants use the LiFT A app, which includes interactive games and exercises, educational content, and tools tailored to young adults using an acceptance and commitment therapy (ACT) treatment approach, for 3 months. Participants also receive associated text messages 2-3 times per week.
  • ARM II: Participants use the LiFT B app, which includes educational resources on preparing to quit, nicotine withdrawal, coping with withdrawal, and mental health, along with health information videos, for 3 months. Participants also receive associated text messages 2-3 times per week.

POST PILOT TRIAL DIARY STUDY PHASE (Objective 3): Participants use the LiFT app and complete daily usability and satisfaction assessments for approximately 1 week. Participants also complete a survey and attend an interview.

Percentage of participants reporting abstinence from all nicotine and tobacco use (excluding Food and Drug Administration-approved pharmacotherapies) over the previous 30 days, biochemically confirmed via saliva cotinine.
At 3 months
Average change in Contemplation Ladder scores (Pilot trial phase)
Tidsram: From baseline to 3 months
The outcome will be calculated as the 3-month follow-up minus baseline score on the 11-point Contemplation Ladder. Positive change scores indicate increases in readiness to quit, on average, whereas negative change scores indicate decreases in readiness to quit.
From baseline to 3 months
Change in acceptance of tobacco use triggers (Pilot trial phase)
Tidsram: From baseline to 3 months
This outcome will be calculated as the 3-month follow-up minus baseline score on the cravings subscale of the Avoidance and Inflexibility Scale. Because avoidance and inflexibility represent the inverse of acceptance, positive change scores indicate a decrease in acceptance, on average, whereas negative change scores indicate increased acceptance of tobacco use triggers.
From baseline to 3 months
Change in values progress (Pilot trial phase)
Tidsram: From baseline to 3 months
This outcome will be calculated as the 3-month follow-up minus baseline score the progress subscale of the Valuing Questionnaire. Positive change scores indicate increases in values progress, on average, whereas negative change scores indicate decreases in values progress.
From baseline to 3 months
Change in values obstruction (Pilot trial phase)
Tidsram: From baseline to 3 months
This outcome will be calculated as the 3-month follow-up minus baseline score the values obstruction subscale of the Valuing Questionnaire. Positive change scores indicate increases in values obstruction, on average, whereas negative change scores indicate decreases in values obstruction.
