What is being measured

The primary outcome is the main question the study is designed to answer.

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.
Measured: 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.
Measured: 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.
Measured: 3-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.
Measured: 3-months post-baseline

Secondary outcomes (12)

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:
1. Use marijuana or marijuana products occasionally
2. Use marijuana or marijuana products regularly
Response options are:
1. No risk
2. Slight risk
3. Moderate risk
4. 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.
Measured: 3-months post-baseline

Measured: 6-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
Measured: 3 months post-baseline

Questions about this trial

What is this clinical trial studying?

A study testing Social Media Intervention in people with Cannabis Use, run by University of Michigan at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 Feb 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Frequency of Cannabis Use as Reported on the Timeline Follow-Back (TLFB) (time frame: 3-months post baseline). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04187989, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2022.
