Introduction: Community interventions have been considered promising strategies to reduce smoking prevalence among ethnic minority populations. We assessed the reach and effectiveness of a community program targeted at the Turkish population in Rotterdam, the Netherlands. Methods: The study had a quasi-experimental design, with 1 pretest and 1 posttest among 18- to 60-year-old Turkish residents in a district in Rotterdam ( n = 388 at pretest) and in a comparison area in the city of Utrecht ( n = 389 at pretest). The surveys included measures of reach and measures of effectiveness. Logistic regression analysis assessed changes in the outcome measures over time, adjusting for sex, age, and educational level. Results: At posttest, more smokers (62.5%) perceived pros of quitting, and 8.2% had quit. Compared with the comparison group, in the intervention group the changes tended to be greater, but differences were not statistically significant. Of all respondents, 61.2% recognized at least 1 program component, and 23.1% participated in at least 1. Conclusions: Based on the greater changes in the intervention group (particularly regarding quit rates and pros of smoking), this community intervention can become a promising strategy. To increase potential effectiveness, participation rates need to increase and interventions should last longer and include smoking-cessation support.
