Information Interventions to Reduce Vaping in a Student Population

Summary

Participants will be allocated to one of two experimental groups using a blocked randomization method; participants will be randomized within blocks such that an equal number are assigned to each treatment. Allocation proceeds by randomly selecting one of the orderings and assigning the next block of participants to study groups according to the specific sequence. Once participants are allocated to one block, each block will be randomly assigned to one of the two interventions. Participants will be randomly divided into one of two blocks, each containing a maximum of 75 participants. Possible treatment allocations within each block are (1) AABB, (2) BBAA, (3) ABAB, etc. This method ensures equal treatment allocation within each block. Each participant will then be assigned a number that will represent the participants' block as well as the participants' individual participant ID number (i.e., Participant '100-123' would be in the same group as participant '100-124'). Groups will be assigned using an Excel file to input participants into subsequent groupings and keep track of questionnaire submissions. At baseline, purpose-questionnaires will be distributed to both groups to assess history and experience with vaping and measure intention to vape less along with the "baseline self-reported questionnaires" that will be administered on Day 1 to all participants. At Day 7 (T1), respective participants will be emailed the attached video link and questionnaires and be instructed to complete the surveys after watching the participants' respective videos. The study intervention will be a single site trial delivered as a video link to the email provided by the participant; both intervention videos will play on YouTube and participants will be instructed to complete the surveys immediately after watching the video attached to the email sent to the participants. The participants will complete self-reported questionnaires at 3 follow-up periods after baseline in the 6-week protocol (all questionnaires will be sent by the student investigator (SI) to the email provided by the participants). Self-reported vaping behaviour questionnaires will be managed at baseline, Day 7 (T1), Day 30 (T2), and Day 45 (T3).

Interventions

BEHAVIORAL

PMT Threat Appraisal

The first half of the PMT present video will include narration by "Science Insider" producer, Benji Jones, including dialogue regarding the risks associated with vaping by Chief Pediatric Pulmonology at the NYU Winthrop Hospital, Dr. Melodi Pirzada, and information on nicotine by the Director of Pediatric Pulmonology at NYU's Langone Hassenfeld Children's Hospital, Dr. Mikhail Kazachkov. The second half of the PMT present video will include personal experiences and narratives by students at the University of Utah with information regarding our current knowledge of vaping health effects through research by Dr. Sean Maddock and Dr. Sean Callahan from the University of Utah to highlight the susceptibility of vaping for a population of young adults in university.

BEHAVIORAL

General Nutrition and Lifestyle

The first half of the PMT absent video will be presented by the Alliance for Aging Research, including an immersive video design, explaining the impact that nutrition may have as the participants age, reviewed by Dr. Steven Austad and Senior Nutritionist Johanna Dwyer. The second half of the PMT absent video will be presented by TED-Ed with narration by Addison Anderson, including a similar immersive video design, explaining how the food the participants eat may affect our brain and overall health. The nutrition and lifestyle information design will be administered as a control because it provides informative lifestyle choices regarding nutrition that can help promote the participants overall health without having an underlying link to vaping behaviour and its subsequent effect on the status of health.
