Using Cognitive Interviewing to Better Assess Young Adult E-cigarette Use

Characteristics of electronic nicotine delivery systems (ENDS) make assessment of their use a challenge for researchers. Cognitive interviews are used in this study to modify a young adult survey and improve assessment of quantity and frequency of ENDS use, as well as reasons for initiation and use of ENDS products. Twenty-five college students participated in individual interviews, which assessed question comprehension, answer estimation, retrieval processes, and answer response processes. The interviews provided valuable insight into survey interpretation that was otherwise inaccessible to researchers.

Who Uses Snus? A Study of Texas Adolescents

This brief report examined (a) differences between adolescent snus users and non–snus users on a variety of demographic, behavioral, and intrapersonal factors and (b) prevalence of snus use among current users of various other tobacco products versus nontobacco users. We found that current users of cigarettes, chew, and cigars had a higher prevalence of snus use than did their peers who did not use the respective products.

Differences between dual users of cigarettes and snus and other tobacco users in the United States: An examination of adolescent males

This study compared adolescent dual users with snus users, cigarette users, and non-users of these tobacco products, on various intrapersonal (e.g., other tobacco use) and interpersonal (e.g., friend use of tobacco) factors. Compared with cigarette users and non-users of either cigarettes or snus, male dual users scored significantly higher on the study variables; there were few differences between dual users and snus users.
