AD IT UP media literacy intervention: AD IT UP was originally developed in 2006 as a classroom-based cigarette prevention program focused on traditional media influences, and was converted to a web-based program in 2011. In 2019, the AD IT UP program was updated substantially to include other forms of tobacco, such as e-cigarettes, and other forms of media, such as social media.

PRIMARY outcome

Timeframe: 1 month

Population: These numbers are the number of students that were present in the classroom on the day of the initial data collection, and thus eligible to participate.

Parents will be asked to return an opt out form if they do not want their student to participate. Students will provide assent if they wish to participate. Recruitment will be determined by calculating the percentage of eligible 9th grade students not opted out by their parents that also provide assent.

PRIMARY outcome

Timeframe: post-test immediately following completion of the intervention

Population: This data is from the intervention students who completed the post-test only.

Acceptability of the intervention will be assessed with closed-ended and open-ended items on the post-test survey immediately following completion of the intervention. Students will be asked on a 5-point Likert scale with responses ranging from Strongly Agree to Strongly Disagree (with a neutral middle) their agreement about the following: "I enjoyed AD IT UP," "I understood AD IT UP," "AD IT UP was easy to use," "I tried my hardest when I was doing AD IT UP," "I think AD IT UP would be helpful to other kids my age," "I would recommend AD IT UP to a friend," and "I agree with AD IT UP's message." An answer of "Strongly Agree" or "Agree" on these items indicates high and moderate acceptability, respectively. Each of these items will be assessed individually, not as an overall scale. Open-ended items will ask: what the student would change about AD IT UP, what the student liked about AD IT UP, what made AD IT UP fun, and what made AD IT UP not fun.

SECONDARY outcome

Timeframe: baseline vs. 12 month follow-up

Population: NOTE: The original analysis was to be conducted for change between baseline and 12-month follow-up. Due to loss to follow-up over the 12-month tme period, the results presented here are for the immediate post-test, for which there was less loss to follow-up.

Items used in this analysis: If one of your best friends offered you a \[NTP\], would you smoke/use it? This item was repeated for cigarettes, hookah, e-cigarettes, and cigars/cigarillos. This item included the a 4-item response scale ranging from Definitely No to Definitely Yes for each of the 4 NTPs. Susceptibility was considered any response except "Definitely No" and totaled for a possible range of 0 to 4. Answering anything other than "Definitely No" on any item is considered susceptible to using tobacco products. These were totaled for a possible range of 0 to 4, with higher scores representing greater susceptibility.

Timeframe: baseline vs. 12 month follow-up

Population: NOTE: The original analysis was to be conducted for change between baseline and 12- month follow-up. Due to loss to follow-up over the 12 month time period, the results presented here are for the immediate post-test, for which there was less loss to follow-up.

Items to measure attitudes toward tobacco products will be included in all 4 surveys. These items include the following with a 10-item response scale ranging from Strongly Disagree to Strongly Agree. E-cigarettes are not as bad for your health as other products. Using tobacco products at parties is fun. (added: Using e-cigarettes at parties is fun) Tobacco products help you deal with problems or stress. Smoking helps people stay thin. People who use e-cigarettes are more fun to be around than people who don't use e-cigarettes. If someone starts using tobacco products every day, it is very hard for them to stop (reverse coded). Smoking makes a person look more attractive. It would be very easy for me to get e-cigarettes if I wanted them. Change in attitudes will be determined by the average increase or decrease in agreement with these items. These items will be assessed individually and as an overall scale (range 0-90, with higher scores indicating a worse outcome).

Items to measure normative beliefs about tobacco products will be included in all 4 surveys. These items ask participants their rate how acceptable the following statements are among their friends using a 10-item response scale ranging from Very Acceptable to Very Unacceptable: It is OK for people your age to smoke cigarettes. It is OK for people your age to use e-cigarettes. It is OK for people your age to use hookahs. It is OK for people your age to smoke cigars or cigarillos. A wealthy person is more likely to use tobacco products than a poor person. A successful person is more likely to use tobacco products than an unsuccessful person. Changes in normative beliefs will be determined by the average increase or decrease in perceived acceptability of these statements. These items will be assessed individually, as well as an overall scale (range 0-60 with higher scores indicating a worse outcome).

Items to measure tobacco-related media literacy will be adapted from the Smoking Media Literacy Scale and included in all 4 surveys. The response scale for these 8 items is a 10-item scale from "Strongly Disagree" to "Strongly Agree." Changes in media literacy will be determined by the average increase or decrease in agreement with these items. These items will be assessed individually, as well as an overall scale (range 0-80, with higher scores indicating a worse outcome).
