Optimizing Hookah Tobacco Public Education Messages to Reduce Young Adult Use

Description

This is a 2-arm randomized controlled trial to test the effects of hookah tobacco public education messages among young adults who are susceptible non-users of hookah tobacco and current hookah tobacco users. Primary outcomes of hookah use behavior will be measured at the 6-month follow-up assessment. Secondary outcomes include curiosity to use hookah tobacco among susceptible non-users and motivation to quit using hookah tobacco among current users. All outcomes are also assessed at 2- and 4-month follow-up time points. All trial participants will be recruited from a US national consumer research panel. Eligible participants will be 1) young adults ages 18 to 30 (inclusive); 2) who have never used hookah tobacco but are deemed susceptible or report hookah tobacco use at least once within the past month; and 3) are enrolled members of the partnering consumer research panel. Panel members will be contacted via email with a brief description of the study and a link to an eligibility screener and online informed consent form. Eligible participants will complete a secure online baseline assessment of demographic characteristics, tobacco use history, and measures of hookah tobacco use behavior, beliefs, attitudes, and perceptions. After completing a baseline, participants will be randomly assigned in approximately equal numbers to one of two arms: 1) hookah tobacco messaging arm; 2) control arm. Through 4 brief study communications delivered approximately weekly, participants will receive study messages to which they are randomized and will complete brief self-report measures online on their responses to the messages. For the hookah tobacco messaging arm, communications will consist of study messages conveying risks of hookah tobacco use with random assignment of the order of messages with each exposure. In response to each message, participants will complete measures of message response and hookah-related beliefs, attitudes, and perceptions. Participants in the control condition will receive study communications with brief messages about health behaviors unrelated to tobacco (e.g., sun protection) and will complete the same measures. Hookah tobacco use behaviors, intentions and curiosity to use hookah tobacco (non-users), motivation to quit (current users), and hypothesized mediators will be assessed 2-, 4-, and 6-months after the message exposure period with the primary outcomes captured at 6-month follow-up.
