Clinical Trial Summary

The goal of this clinical trial is to use psychophysiological methods to test the effects of a message source (expert and peer) and message presentation types (one-sided and two-sided) to identify the optimal message type for young adults who vape and do not vape.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Visual attention	Participants will view one of four text-based e-cigarette education messages that are manipulated on the source and message presentation type. Participants will be randomly assigned to one of the following message type: 1) expert one-sided, 2) expert two-sided, 3) peer one-sided, 4) peer two-sided. We selected messages that were previously tested for effective themes and contents with young adults and adapted the features to two source (expert and peer) and presentation (one-sided and two-sided) types. Higher scores indicate greater visual attention.	45 minutes
Primary	Orienting response	Orienting response, conceptualized as cognitive resources allocated to encode a message into working memory will be operationalized as heart rate using a Shimmer3 Unit with an electrode placed on the forefinger of the non-dominant hand. This is a well-established measure for cognitive resources devoted to stimuli processing. Lower scores indicate greater cognitive allocation of resources.	45 minutes
Primary	Arousal	Arousal, an indicator of physiological activation in the sympathetic nervous system, will be measured by sampling skin conductance using a 30 Hz Shimmer Galvonic Skin Response on finger sensors.Higher scores indicate greater arousal.	45 minutes
Secondary	Attitudes	Attitudes will be measured by seven-item vaping attitudes questionnaire, such as vaping is unenjoyable/enjoyable, unhealthy/healthy, dangerous/safe, boring/fun, stupid/smart, not cool/cool, and not attractive/attractive on a five-point bipolar scale. Higher scores indicate worse outcomes.	45 minutes
Secondary	Behavioral intentions	Behavioral intentions to vape will be measured by a three-item behavioral intentions questionnaire, such as intentions to vape (for vapers)/try vaping (for non-vapers) soon, anytime during the next year, would use offered by one of their best friends on a scale from 1 (Definitely not) to 5 (Definitely yes). Higher scores indicate worse outcome.	45 minutes
