Adolescent smoking: attitudes, norms and parental influence.

The self-reported smoking habits and intentions of over 10,000 adolescents, aged 11 to 16 years, were related to a variety of attitudinal and normative variables. Current or previous smoking experience was a more important predictor of future intention to smoke than attitude or subjective norm (others' perceived tolerance of subjects' smoking). Parental opposition to smoking was a more important direct predictor of subjects' smoking intention than parental smoking behaviour.
