Trial Outcomes & Findings for Consumer Perceptions of Cannabidiol (CBD) Health Claims (NCT NCT06069713)
NCT ID: NCT06069713
Last Updated: 2024-12-30
Results Overview
The primary outcome is consumer perception of the claims in the ads (n=55) and whether perceptions of prohibited claims vary by CBD use status. After viewing each of the 5 assigned ads participants will respond to six items that assess their perception of the prohibited claims made in the ads, including 1) drug effect 2) FDA approved/ endorsed 3) dietary supplement 4) food additive 5) false/misleading (scientific) and 6) false/misleading (targeting youth). The Study Team will use a 5-point response scale, (1) Not at all to (5) Extremely to assess perception of each prohibited claim type. For each use status group, the Study Team will report the overall mean score (all ads together) for each claim type to indicate if perception of prohibited claims differed by use status.

PRIMARY outcome
Timeframe: Minute 15Population: participants were pre-specified to be reported "per CBD user status"
The primary outcome is consumer perception of the claims in the ads (n=55) and whether perceptions of prohibited claims vary by CBD use status. After viewing each of the 5 assigned ads participants will respond to six items that assess their perception of the prohibited claims made in the ads, including 1) drug effect 2) FDA approved/ endorsed 3) dietary supplement 4) food additive 5) false/misleading (scientific) and 6) false/misleading (targeting youth). The Study Team will use a 5-point response scale, (1) Not at all to (5) Extremely to assess perception of each prohibited claim type. For each use status group, the Study Team will report the overall mean score (all ads together) for each claim type to indicate if perception of prohibited claims differed by use status.

SECONDARY outcome
Timeframe: Minute 15For each ad that the participant views (n=5), the Participant will respond to a one-item measure that assesses the extent to which the participant perceives that CBD is safe to consume. Response options are on a 1 to 5 scale, with higher scores representing more perceived safety (i.e. 1- Not at all safe to 5- Extremely safe). For each use status group, the Study Team will report the mean score of perceived safety to indicate if the perceived safety of CBD in the advertisements differed by use status.

Response options are on a 1 to 5 scale, with higher scores representing more appeal (i.e. 1- Not at all appealing to 5- Extremely appealing). For each use status group, the Study Team will report the mean score of appeal to indicate if the appeal of CBD in the advertisements differed by use status.

OTHER_PRE_SPECIFIED outcome
Timeframe: Minute 15Ten items will measure participants' perceptions about the possible effects of CBD. Response items are on a 1 to 5 scale, with higher scores representing more agreement with the stated effect (i.e. 1- Strongly disagree to 5- Strongly agree).
Outcome measures

OTHER_PRE_SPECIFIED outcome
Timeframe: Minute 15Seventeen items will measure participants' perceived benefits of daily CBD use to treat various medical conditions. Response items are on a 1 to 4 scale (1-Worsen the condition; 2- No effect on the condition; 3-Improve the condition; 4- I don't know)
Outcome measures
