Misura Descrizione
Lasso di tempo
TID beliefs in parents
Lasso di tempo: 1 month
Parents will report their opinions towards 4 sentences: 1) Tobacco companies are a respectable industry; 2) the tobacco industry does everything it can to get young people to smoke; 2) the tobacco industry use many tactics to resist tobacco control regulations; 4) the tobacco industry deceived the public for financial interests. All the 4 questions have 5 options from definitely yes to definitely no.
