Social Media Intervention for Cannabis Use in Emerging Adults

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to develop and test social media interventions to help young people increase well-being and reduce risky behaviors. The study will help researchers learn about ways to deliver wellness information in a way that is appealing and helpful to young people who use Facebook.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Frequency of Cannabis Use as Reported on the Timeline Follow-Back (TLFB) | 30-day TLFB self-report will be used to assess total number of days of cannabis use. | 3-months post baseline | 
| Frequency of Cannabis Use as Reported on the Timeline Follow-Back (TLFB) | 30-day TLFB self-report will be used to assess total number of days of cannabis use. | 6-months post baseline | 
| Quantity of Cannabis Used as Reported on the Timeline Follow-Back (TLFB) | 30-day Timeline Follow-Back (TLFB) self-report will be used to assess quantity (grams) of cannabis consumed. | 3-months post baseline | 
| Quantity of Cannabis Used as Reported on the Timeline Follow-Back (TLFB) | 30-day Timeline Follow-Back (TLFB) self-report will be used to assess quantity (grams) of cannabis consumed. | 6-months post baseline | 
| Consequences of Cannabis Use as Measured by the Marijuana Adolescent Consequences Questionnaire Using Dichotomous Response Scale as Previously Described Throughout This Trial Registration. | Marijuana Adolescent Consequences Questionnaire will be used to assess past 3 month consequences of cannabis use. Consequences are measured by report of number of times incidents from the list of 26 items (e.g., quality of work suffered, had less energy, etc.) resulted from cannabis use. Responses will be dichotomized (0 = never, 1= greater than never) and summed for a total score reflecting total number of consequences. Response scale: Never 1-2 times 3-5 times 6-10 times More than 10 times Minimum score =0, maximum = 26. Higher score = more consequences. | 3-months post-baseline |

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Perceived Risk of Cannabis Use as Measured by 2 Modified Items From the Monitoring the Future Survey | Two items rating current opinion on a scale from no risk to great risk of their perceived risk harm from occasional cannabis use and regular use. Items are-- How much do you think people risk harming themselves (physically or in other ways), if they: Use marijuana or marijuana products occasionally Use marijuana or marijuana products regularly Response options are: No risk Slight risk Moderate risk Great risk Answers from both items are added together. The total range of two items summed can be 2-8. Higher totals indicate higher perceived risk. | 3-months post-baseline |

| Peer Approval/Disapproval of Cannabis Use as Measured by Item Modified From Monitoring the Future Survey | One item rating of current perception of whether their close friends would disapprove of their cannabis use (regardless of how much they use), rated as: Not disapprove Disapprove Strongly disapprove | 3 months post-baseline | 
| Peer Approval/Disapproval of Cannabis Use as Measured by Item Modified From Monitoring the Future Survey | One item rating of current perception of whether their close friends would disapprove of their cannabis use (regardless of how much they use), rated as: 1 Not disapprove 2 Disapprove 3 Strongly disapprove | 6 months post-baseline | 
| Cannabis Impaired Driving as Measured by 5 Items From the Modified Young Adult Driving Questionnaire | Five items from the modified Young Adult Driving Questionnaire will be used to assess past 3 month driving under the influence of cannabis. Response values will be summed for a total score. In the PAST 3 MONTHS...how many times did you drive within one hour after using marijuana or marijuana products containing THC? how many times did you drive while a little high on marijuana or marijuana products containing THC? how many times did you drive while very high on marijuana or marijuana products containing THC? how many times did you drive when you knew your use of marijuana/marijuana products containing THC may already have affected your coordination? how many times did you ride in a car or other vehicle driven by someone who had been using marijuana or marijuana products containing THC? Response options: 0= Never Once Twice 3 times 4 times 5 times 6-9 times 10 or more times | 3 months post-baseline |

| Other Drug Use as Measured by Items Modified From Monitoring the Future Survey | Items from the Monitoring the Future Survey will be used to assess past 30 day use of 6 other substances - substances used and number of times of use. Response values will be summed for a total score using mid-point of the range scoring. Substances assessed include: hallucinogens, opioids, stimulants, sedatives, lsd, ecstasy Response scale: 0 0 Occasions 1-2 Occasions 3-5 Occasions 6-9 Occasions 10-19 Occasions 20-39 Occasions 40 or More Occasions | 3 months post-baseline |
