Responses to E-Cigarette Advertising

Overview

While conventional cigarette use continues to decline among youth and young adults, e-cigarette (EC) use is on the rise. The use of ECs during young adulthood, particularly 18 years of age, is especially alarming because it is not only a critical period in development but also a time when tobacco use is established. Additionally, the tobacco industry targets individuals of this age with the hope that they will one day progress to using combustible cigarettes. Advertising may be one of the reasons leading young people to use ECs, and the Food and Drug Administration (FDA) now has the authority to regulate EC advertisement features. The goal of the study is to determine which EC ad features most strongly influence young adults' attitudes, susceptibility, and intentions to use ECs. Fifteen ads from the most popular EC brands that employ a brand, product descriptions, and modeling features were selected. Young adults who are susceptible to EC use will come into the lab and view these ads. During exposure, they will be assessed for real-time visual attention using eye-tracking, orienting responses using heart rate, and arousal using skin conductance as well as pre- and post-ad self-report measures of attitudes, susceptibility, and behavioral intentions. These factors will help determine the most high impact features, which will be associated with the greatest visual attention, orienting responses, and arousal levels and changes in attitudes. Findings from this study will provide public health officials important and urgently needed information as to what advertising features are contributing to the sharp rise in the use of ECs among young adults.

  • Experimental: E-Cigarette Ads
    • All individuals in the study will see the same e-cigarette advertisements presented in a random order.

Clinical Trial Outcome Measures

Primary Measures

  • Attention to Specific ad Feature
    • Time Frame: Change from the first second of viewing to each subsequent second of the intervention (10 seconds per ad), averaged for each participant.
    • Heart rate was measured to assess the cognitive resources allocated to the message. Using three sensors applied to participants’ fingers, electrocardiogram (ECG) signals were recorded with a Shimmer 3 EXG module, while viewing the advertisements and were sampled at 512 Hz. Heart change scores were computed using beats per minute (BPM) and subtracting the first second of the stimuli (participant had seen a black screen just prior) from scores for each second of message exposure for each participant. Then, scores were averaged across each advertisement. Lesser values indicated greater deceleration in heart rate, signaling more cognitive resources allocated to the message.
  • Arousal
    • Time Frame: The average amplitude of skin conductance peaks over the 10 second viewing window for each ad brand.
    • Skin conductance or galvanic skin response was measured using three sensors applied to participants’ fingers. Skin conductance measured if there was an emotional response and the intensity of the emotional response. A “peak” is a biological indicator that something happened, and the participant had an emotional response to it. The amplitude of each peak for each participant was measured and averaged per ad.
  • Attention to Specific ad Feature
    • Time Frame: Duration of seconds spent on all areas of interest during 10 second viewing window for each ad brand
    • Visual attention was assessed using an eye-tracker connected to the base of the computer screen. For each message, four areas of interest (AOI) were identified: 1) brand, 2) descriptor, 3) modeling, and 4) warning. All four AOIs were summed for a total number of milliseconds that a participant viewed the AOIs.

Secondary Measures

  • Motivations to Avoid E-cigarettes
    • Time Frame: Immediately after viewing each ad
    • Self-report Please rate on a scale from 0 (not at all) to 10 (very much). “How important is it to avoid e-cigarettes in the future?” “How confident are in avoiding e-cigarettes in the future?” “How ready are you to avoid e-cigarettes in the future?” “How committed are you to avoid e-cigarettes in the future?” Scores were averaged for each ad for each participant. Then, an overall average was taken among all participants for each ad. Higher values indicate greater motivation to avoid e-cigarettes.
