## Brief Summary

This trial studies how well text messages work in preventing tobacco use in young adults. Text messaging may help to teach young adults about the risks of tobacco products.

## Detailed Description

PRIMARY OBJECTIVES:

I. To assess baseline knowledge and risk perceptions about the use of conventional and new and emerging tobacco products among a subset of community college students from the two participating Houston Community College (HCC) campuses (Central and Coleman campuses). (Phase 1.1) II. Test the text messages with university students enrolled in the health communications academic programs. (Phase 1.2) III. Assess the awareness, attitudes, receptivity, and comprehension of the harmful effects of conventional and new and emerging tobacco products among young adults. (Phase 2) IV. Identify the most effective combinations of text message framing for communicating information about the potential harmful effects of tobacco products to young adults. (Phase 2) V. To obtain an objective measure of the psychological (i.e., emotional and cognitive) effect of the messages on young adults. (Phase 3)

EXPLORATORY OBJECTIVES:

I. Define and analyze key moderators of young adult awareness, attitudes, receptivity, and understanding of the harmful risks and constituents of conventional, new and emerging tobacco products. (Phase 2)

OUTLINE:

PHASE I: Participants attend focus group over 2 hours.

PHASE II: Participants receive 2 text messages per day for 30 days at baseline and after 3 months.

PHASE III: Participants read 64 computer messages with or without images over 30 minutes and have their facial expressions assessed.

- **Maximum age:** 25 Years
- **Sex:** ALL
- **Healthy Volunteers:** Yes

```

## Arms

- **Prevention (text messages, computer messages)** (EXPERIMENTAL) — PHASE I: Participants attend focus group over 2 hours.

PHASE II: Participants receive 2 text messages per day for 30 days at baseline and after 3 months.

PHASE III: Participants read 64 computer messages with or without images over 30 minutes and have their facial expressions assessed.

## Interventions

- **Computer-Assisted Intervention** (OTHER) — Read computer messages
- **Focus Group** (BEHAVIORAL) — Attend focus group
- **Informational Intervention** (OTHER) — Receive text messages
- **Survey Administration** (OTHER) — Complete surveys about experience

## Primary Outcomes

- **Baseline knowledge and risk perceptions of Tobacco Use Questionnaire** _(time frame: Up to 8 months)_ — Participants will take baseline knowledge and risk perceptions about the use of conventional and new and emerging tobacco products among a subset of community college students from the two participating Houston Community College (HCC) campuses (Central and Coleman campuses) Knowledge about whether products contain nicotine scale Yes or No (0-1) A higher score indicates higher knowledge Risk perception for using tobacco products scale from( 1-5) A higher score indicates a higher perception of risk of harm. No scale being used.
- **Focus Groups Questionnaire** _(time frame: Up to 8 months)_ — No scale being used. Participants will take part in use of text messages within the university students enrolled in the health communications academic programs. Students will review and rate the messages with the goal of achieving 70% agreement among students across each text message. No scale will be used.
- **Perceived Risk Perception changes amongst young adults Questionnaire** _(time frame: Up to 8 months)_ — Participants will show the awareness, attitudes, receptivity, and comprehension of the harmful effects of conventional and new and emerging tobacco products among young adults. 4-point Likert Scale. Higher scores will endorse beliefs for greater benefits of electronic cigarette use. 3-point Likert scale higher score endorse greater addictiveness. Risk perception for using tobacco products. Response format 1-5. A higher score indicates a higher perception of risk of harm. No scale being used.
- **Information seeking and avoidance about tobacco products Questionnaire** _(time frame: Up to 8 months)_ — Participants will identify the most effective combinations of text message framing for communicating information about the potential harmful effects of tobacco products to young adults. Risk perception for using tobacco products. Response format 1-5. A Higher score indicates a higher perception of risk of harm. No scale being used.

## Secondary Outcomes

- **Risk perceptions related to tobacco products Questionnaire** _(time frame: Up to 8 months)_
