Directors of and contact teachers for addiction prevention from Swiss vocational schools in the cantons of Aargau,
Basel, Berne, and Zurich were invited to have some of their
classes participate in a study testing the efficacy of a text
messaging-based smoking cessation program. Research
assistants invited all students in participating vocational
school classes to participate in an anonymous online health
survey during a regular school lesson reserved for health
education. Participation was voluntary. The online survey
included data collection of information about demographics,
perceived stress, physical activity, body weight, alcohol
consumption, smoking status, mobile phone ownership, and
mobile phone type (smartphone or other). As part of this
survey, students that smoked cigarettes daily or occasionally
and owned a mobile phone were invited to participate in a
3-month text message-based program that provided information about smoking tobacco. Details of the program are
presented in Haug et al. (2014).
