Summary
A minimal tailored intervention significantly increased short-term quit attempts. Long-term, combining outcome and self-efficacy information supported continuous abstinence in smokers.
Area of Science:
- Public Health
- Behavioral Science
Background:
- Short-term efficacy of tailored interventions for smoking cessation is established.
- Long-term effectiveness of single, brief tailored interventions requires further investigation.
Purpose of the Study:
- To evaluate the 14-month efficacy of a minimal tailored intervention for smoking cessation.
- To compare the effects of outcome information, self-efficacy information, and a combination of both, against a no-information control group.
Main Methods:
- Smokers were randomly assigned to receive tailored information (outcome, self-efficacy, or both) or no information via mail.
- Participants were assessed at a 14-month follow-up for quit attempts and continuous abstinence.
Main Results:
- All intervention groups showed significantly more 24-hour quit attempts compared to the control group.
- No intervention group achieved significantly higher 7-day quitting rates than the control group.
- The combined outcome and self-efficacy information group demonstrated significantly higher continuous abstinence rates at 14 months.
Conclusions:
- A brief, six-page tailored intervention can support smoking cessation.
- Combining outcome and self-efficacy information appears most effective for long-term continuous abstinence.
