Flavor additives in e-cigarettes may play a role in e-cigarette initiation, dual use, and switching among young adult combustible tobacco product (cigarette/little cigar/cigarillo) smokers, but gaps remain in the availability of measurement tools that can assess how flavors influence e-cigarette use behaviors. The goal of this study is to develop a flavor outcome expectancies scale that can help quantify the role of flavors in e-cigarette trajectories among young adult cigarette and/or little cigar/cigarillo smokers. This study builds on five previously-completed concept mapping studies that yielded more than 100 user-generated statements that describe positive and negative flavor experiences. Study aims are: (1) to use the statements to develop items for the flavor outcome expectancies scale; (2) to establish the content validity of the scale and test the scale items using cognitive interviews; and (3) to pilot test the scale, examine the internal consistency and factor structure, and investigate the concurrent and construct validity of the scale. First, researchers will reduce and revise relevant concept mapping statements and obtain feedback from an expert panel on the content validity and structure of the items. Next, researchers will conduct cognitive interviews (n=10) and focus groups (n=24) among young adult cigarette and/or little cigar/cigarillo smokers ages 18-35 to examine their understanding of the items. Finally, researchers will recruit smokers who have never used e-cigarettes (n=140) and smokers who currently use e-cigarettes (n=140) to complete an online survey that will allow the researchers to examine the structure of the scale and test its validity. This project will provide new information about the role of flavors in e-cigarette initiation, dual use, and switching by young adult smokers.
