OBJECTIVE
To compare the effectiveness of group advanced intervention and individual advanced intervention for smoking management in primary health care; b) to know if in group intervention exists an added positive effect due of the group and, if this is true, to characterize it; and c) to know the advantages and inconvenients that the participants attribute to each intervention.


METHODS

Depth interview will be done for qualitative study. PRINCIPAL MEASUREMENT: Maintained cessation during 12 months confirmed by expired-air carbon monoxide measurement. SECONDARY MEASUREMENTS: Self-declared cessation and confirmed by expired-air carbon monoxide measurement months 1, 2, 3, 6, and 9, and tobacco reduction if there isn't abandonment.


METHODS
Intention treatment. Multilevel analysis will be done to determinate the positive effect added of the group if it's proved that exists. Content analysis for qualitative study.
