Brief summary

The investigators primary hypothesis was that recipients of the Motivational Interviewing intervention would be significantly more likely than those assigned to the Psychoeducation intervention to demonstrate increased readiness to quit smoking at the end of the intervention and to seek smoking cessation treatment in the one month period following the intervention. We also predicted that the Psychoeducation intervention would result in greater improvements in smoking knowledge.
