The study was advertised as a focus group study with young adult 18—35 year old e-cigarette users. Interested individuals telephoned the research site and were screened by a research staff. Participants were required to be 1 current daily e-cigarette users; 2 between 18 and 35 years in age; 3 fluent in English; and 4 able and willing to travel to the research site. Verbal consent was obtained from the participants before the screening was conducted.
Thanks to a recent study, this is now scientifically verifiable. One way en route for investigate the issue is to acquaint with women with hypothetical men with altered personality types and see which ones they prefer. In one such analyse , participants had to help a fictional character named Susan choose a date from three male contestants, based on their answers to her questions. In one version, the man was nice — he was in affect with his feelings, caring and benevolent. The third contestant simply gave disinterested answers. So which contestant did participants think Susan should date and who did they prefer to date themselves?
