- Lead Sponsor
- University of Massachusetts, Worcester
- Brief 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.

Group Intervention Description Source Expert Participants in the source arm will receive e-cigarette education messages manipulated in one of two source types. Source Peer Participants in the source arm will receive e-cigarette education messages manipulated in one of two source types. Sidedness 1 Sided Participants in the sidedness arm will receive e-cigarette education messages manipulated in one of two sidedness types. Sidedness 2 Sided Participants in the sidedness arm will receive e-cigarette education messages manipulated in one of two sidedness types.
- Primary Outcome Measures
Name Time Method Visual attention 45 minutes 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.
Arousal 45 minutes 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.
Orienting response 45 minutes 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.
- Secondary Outcome Measures
Name Time Method Attitudes 45 minutes 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.
Behavioral intentions 45 minutes 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.
