Social learning theory and de-normalisation of smoking

There are many smoking prevention programmes based on the information and fear arousal approach addressing the
long-term negative health consequences of smoking.1,2 However, these programmes show only very limited effects on actual
behaviour and attitudes in young people.3,4 In contrast to the “traditional” approaches, the theoretical foundation of the
Smokefree Class Competition is social learning theory and the de-normalisation of smoking, two of the most influential
approaches in modern prevention research.5,6

Peer influence and normative beliefs

The Smokefree Class Competition is carried out as a class initiative, because peer smoking is one of the most
relevant risk factors for smoking onset in adolescence.7,8

Conducting the competition as a class initiative also serves to strengthen non-smoking as the “normal” behaviour and
to correct false normative beliefs about smoking in pupils.

Focusing on normative behaviour and commitment are evidence-based criteria for successful drug prevention programmes.9

Interactive delivery of the programme

Both, the regular discussions on smoking and further creative class activities in class are interactive ways to address the
subject non-smoking. Pupils are not merely informed about the harmful effects on smoking but encouraged to engage themselves
in creative activities to learn more about smoking, motives for smoking onset and environmental, physical and ecological
consequences of smoking.

A meta-analyses based on 207 studies showed that interactive learning has the best effects on smoking prevention in youth.10

In summary, the initiative is based on broad evidence on successful drug prevention methods.
