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.
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.
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.

Participants also receive LiFT B text messages 2-3 times per week. |
|

| Measure | Description | Time Frame |
|---|---|---|
| Overall satisfaction (Pilot trial phase) | Overall satisfaction with the assigned program will be assessed by self-report on a 5-point Likert-type scale from "not at all" (1) to "very much" (5) and summarized by arm using means and standard deviations. | At 3 months |
| Number of logins to assigned application (Pilot trial phase) | Treatment utilization will include number of logins to the assigned application, determined objectively using tracking software. | At 3 months |
| Usefulness of the program (Pilot trial phase) | The perceived usefulness of the assigned program will be assessed by self-report on a 5-point Likert-type scale from "not at all" (1) to "very much" (5) and summarized by arm using means and standard deviations. | At 3 months |
| Usefulness of text messages (Pilot trial phase) | The perceived usefulness of the assigned program's text messages will be assessed by self-report on a 5-point Likert-type scale from "not at all" (1) to "very much" (5) and summarized by arm using means and standard deviations. | At 3 months |
| Satisfaction with perceived tailoring (Pilot trial phase) | The perception that the assigned program was made for someone like the participant will be assessed by self-report on a 5-point Likert-type scale from "not at all" (1) to "very much" (5) and summarized by arm using means and standard deviations. | At 3 months |
| Satisfaction with guidance on how to quit (Pilot trial phase) | The perception that the program clarified how to quit nicotine/tobacco when ready will be assessed by self-report on a 5-point Likert-type scale from "not at all" (1) to "very much" (5) and summarized by arm using means and standard deviations. |
| Measure | Description | Time Frame |
|---|---|---|
| Biochemically-confirmed 7-day point prevalence abstinence (PPA) from all nicotine and tobacco use (Pilot trial phase) | Percentage of participants reporting abstinence from all nicotine and tobacco use (excluding Food and Drug Administration-approved pharmacotherapies) over the previous 7 days, biochemically confirmed via saliva cotinine. | At 3 months |

| Perception that program offered a novel approach to quitting (Pilot trial phase) | The perception that the program offered a new way of looking at quitting will be assessed by self-report on a 5-point Likert-type scale from "not at all" (1) to "very much" (5) and summarized by arm using means and standard deviations. | At 3 months |
| Perceived helpfulness for quit preparation (Pilot trial phase) | The perception that the program will help with quitting if/when ready will be assessed by self-report on a 5-point Likert-type scale from "not at all" (1) to "very much" (5) and summarized by arm using means and standard deviations. | At 3 months |
| Willingness to recommend program to a friend (Pilot trial phase) | Whether the respondent would recommend the program to a friend will be assessed via responses of "yes," "no," or "not sure." Responses will be categorized into a binary variable representing "yes" versus other responses (i.e.,"no" or "not sure"). | At 3 months |
| Usability (Post pilot trial diary study phase) | Qualitative data from interviews, diary entries and exit interviews will be coded and analyzed using rapid inductive content analysis to extract themes. Usability data will be reported using descriptive statistics and compared against the benchmark score of 68, which represents average usability. | At completion of post pilot trial diary study phase (At Day 9) |
| Self-reported 7-day PPA from all nicotine and tobacco use (Pilot trial phase) | Percentage of participants reporting abstinence from all nicotine and tobacco use (excluding Food and Drug Administration-approved pharmacotherapies) over the previous 7 days. | At 3 months |
| Self-reported 30-day PPA (Pilot trial phase) | Percentage of participants reporting abstinence from all nicotine and tobacco use (excluding Food and Drug Administration-approved pharmacotherapies) over the previous 30 days. | At 3 months |
