Outcome Measures

Primary Outcomes (1)

  • The change in smoking prevalence between baseline and 24 months of follow-up between the two groups measured via questionnaires.

    The change in smoking prevalence between baseline and 24 months of follow-up between the two groups. A smoker is defined as someone who claims to have smoked cigarettes at least once in the past 30 days.

    24 months post intervention

Secondary Outcomes (5)

  • Difference in attitude towards smoking between the two groups at 24 months follow-up measured via questionnaires.

    24 months post intervention

  • The change in never-smokers between baseline and 24 months of follow-up between the two groups measured via questionnaires.

    24 months post intervention

  • The difference in the number of quitters (=cigarette smokers at baseline but not at endline) between baseline and 24 months of follow-up between the two groups measured via questionnaires.

    24 months post intervention

  • The difference in the number of starters (=starters are participants who are not cigarette smokers at baseline but at endline) between baseline and 24 months of follow-up between the two groups measured via questionnaires.

    24 months post intervention

  • The change in smoking prevalence between baseline and 24 months of follow-up between female participants of the two groups measured via questionnaires.

    24 months post intervention

Study Arms (2)

Intervention

EXPERIMENTAL

Schools in this arm receive a photoaging mobile app promoting poster campaign revealing the effects of smoking on the users face via a self portrait (i.e. a "selfie").

Behavioral: Photoaging mobile app promoting poster campaign.

Control

NO INTERVENTION

The control group consists of schools participating in the survey but not receiving the intervention.
