This study evaluate the effectiveness of a nurse multi-component intervention aimed at helping Spanish college student smokers to quit smoking.
This study hipotetize that a multicomponent intervention, tailored to college student and conducted by a nurse is more effective than brief advise.
The intervention was a multi-component intervention based on the Theory of Triadic Influence and on previous recommendations made in the Surgeon General's report . The strategies of this program consisted of a 50-minute motivational interview conducted by a nurse and online self-help material. The follow-up included a reinforcing e-mail and group therapy. The smoking-related Self-efficacy, Belief and Intention scale was used to assess outcomes.
Exclusion Criteria
The intervention group consisted in face-to-face 50-minute meeting \[motivational interviewing (MI)\]; online self-help material focused on: (1) decisions; (2) moods; (3) social life; (4) smoking health effects; and (5) quitting; e-mail 15 days before the MI, group therapy 2 months after the MI (60 minutes), a second follow-up visit 4 months after the MI (20 minutes).
Behavioral: Multicomponent intervention
The control group received a brief advice (5-10minutes) and a self-help pamphlet called 'Stop smoking'. Before giving brief advice, the nurse assessed smokers' habits and their willingness to quit. As is usually in this type of studies there were no follow-up sessions for this group.
