Outcome Measures

Primary Outcomes (4)

  • Use Intention Susceptibility

    This 3-item self-report measure assesses participant interest in trying the vaping device in the future. A 4-level Likert scale is used: definitely not, probably not, probably yes, definitely yes.

    5 minutes

  • Perceived Health Harms

    This 2-item self-report measure assesses participant perception of health harms and risks associated with using the vaping product. A 4-level Likert scale is used: definitely not, probably not, probably yes, definitely yes.

    5 minutes

  • Anticipated Subjective Effects

    This 9-item self-report measure assesses anticipated subjective effects from using the vaping device. Participants will select all that apply.

    5 minutes

  • Anticipated Impairment/Enhancement

    This 4-item self-report measure assesses participant anticipated enhancement or impairment effects on completing different activities due to using the vaping product. A 5-level Likert scale is used: definitely make it harder, probably make it harder, no effect, probably make it easier, definitely make it easier.

Interventions

Participants will view one vape image (experimental stimulus) and are randomized to a label presented and the color/flavor of the vaping device presented. The label conditions are: 1. plain (i.e., no labeling on device) 2. "contains THC" 3. "contains 80% THC" 4. "contains 80% THC - HIGH POTENCY" 5. "contains nicotine" 6. "contains 5% nicotine" 7. "contains 5% nicotine - HIGH STRENGTH" The color/flavor conditions are: mint/mint, white/original, blue/blueberry.
