Background: In Costa Rica, the leading cause of preventable death is smoking. Adults spend one third of their lives at work making the workplace an optimal site for smoking cessation interventions. Therefore, we developed a workplace smoking cessation pilot program among Costa Rican Justice Department government employees based on key Costa Rican values and best practices. Methods: First, focus groups were conducted among exsmokers and smokers. Participants in the focus groups and in the subsequent smoking cessation pilot study were invited to take part in the study through flyers, information sheets, and announcements from the Justice Department. The focus groups revealed that social factors were fundamental to quitting. Therefore, based on these results two programs (14 participants) were conducted consisting of seven sessions encouraging employees to utilize their family and exsmokers. Data were collected before and after the seven sessions on smoking behavior, social influence, and other factors. Findings: Five of 14 (36%) quit smoking. None of the quitters lived with a smoker, as compared with 56% of nonquitters who lived with a smoker. Also, quitters were less likely to have friends (40% vs. 67%) and coworkers (20% vs. 33%) who smoked compared with nonquitters. Conclusion/Application to Practice: Workplace smoking cessation programs should help smokers to increase their social contacts with nonsmokers/exsmokers. Smoking cessation programs should assess not only smoking patterns, but also social contacts, such as family, friends, and coworkers. Based on these assessments, smokers should be encouraged to seek-out nonsmokers/exsmokers to assist them in quitting.
