Trial Outcomes & Findings for Impact of E-Cigarette Prevention Messages on Adolescents (NCT NCT05985538)
NCT ID: NCT05985538
Last Updated: 2025-08-22
Results Overview
The mean susceptibility to vaping score will be assessed using the questionnaire. Response options are on a 1 to 4 scale. Overall scale scores are determined by summing scores of the 3 items and dividing them by 3 (range 1-4), with higher scores representing a greater susceptibility to vaping (a worse outcome).

Vaping prevention text messages: Participants will receive text messages (2 daily, on average) about the harms of e-cigarette use and vaping for 28 days, with introductory messages sent on day 1 and concluding messages sent on day 28. Each vaping prevention text message will focus on one of six topics: nicotine addiction, monetary costs of vaping, chemical exposures from e-cigarette vapor, cosmetic effects of vaping, mental and physical use symptoms of vaping, and health impact on organs from vaping. Some text messages will ask participants for a reply (i.e., two-way messages).
