Tobacco Use and Secondhand Smoke Exposure: Incentives and Competitions to Increase Smoking Cessation Among Workers – When Used Alone


What the CPSTF Found

About The Systematic Review

The CPSTF finding is based on evidence from a systematic review which identified only one study (search period January 1980–March 2005).

The systematic review was conducted on behalf of the CPSTF by a team of specialists in systematic review methods, and in research, practice, and policy related to reducing tobacco use and secondhand smoke exposure.

Summary of Results

Detailed results from the systematic review are available in the CPSTF Finding and Rationale Statement pdf icon [PDF - 132 kB].

The systematic review identified one study.

  • Over a 12-month intervention period, 32.8% of the baseline participants continuously abstained from using tobacco.
  • Verified cessation rates were 49% at six months and 36% at 12 months into the contest period.

Summary of Economic Evidence

An economic review of this intervention was not conducted because the CPSTF did not have enough information to determine if the intervention works.


Applicability of this intervention across different settings and populations was not assessed because the CPSTF did not have enough information to determine if the intervention works.

Evidence Gaps

Additional research and evaluation are needed to answer the following questions and fill existing gaps in the evidence base.

  • Are there settings where worksite-based incentives or competitions when implemented alone are effective?
  • Would it make a difference if incentives or rewards were offered for things other than tobacco cessation (e.g., for achieving personal health goals)?

Study Characteristics

  • The one study from Sweden evaluated a worksite-based tobacco cessation contest with a precontest promotion, an enrollment period, biochemical verifıcation of self-reported abstinence at each assessment, and three lottery drawings over a 12-month intervention period (at one, 6, and 12 months).
  • 10% of tobacco-using workers participated in the intervention.
