Abstract

Electronic cigarette (e-cigarette) use among adolescents has rapidly increased in recent years, especially among Latinx and non-Latinx Black adolescents. Yet, limited research exists on adolescent attitudes that may contribute to the popularity of these products. This is in part due to the lack of measures focused on assessing adolescent attitudes towards e-cigarette use. The aim of this study was to develop a measure of adolescent e-cigarette use attitudes. The sample consisted mainly of Latinx and non-Latinx Black adolescents. Data were collected from 247 youth (M age = 16.0, SD = 1.2), 63.6% were girls, a majority (69.2%) were non-Latinx Black, and 27.1% were Latinx. The Electronic Cigarette Attitudes Survey (ECAS) is comprised of 12 items reflecting attitudes associated with e-cigarettes, which were derived from prior theoretical, quantitative, and qualitative work with e-cigarette users. To determine the factor structure, a parallel analysis scree plot and an exploratory factor analysis (EFA) of the ECAS was conducted using half of the sample chosen at random (n = 113). Results supported a one-factor solution. A confirmatory factory analysis (CFA) was conducted on the other randomly chosen half of participants (n = 121). Results confirm a one-factor solution. No significant differences were found on ECAS scores based on race/ethnicity or e-cigarette use status (lifetime e-cigarette use vs. no use). The ECAS represents a viable measure for assessing e-cigarette attitudes among youth.
