The objective of this research project is to evaluate the process of delivering an intervention designed to reduce ETS exposure among Latino children by trained community health advisors (CHAs).


Although the negative health consequences of tobacco use among smokers have long been established, research also has established smoking-exposure illnesses in nonsmokers. Environmental tobacco smoke (ETS), commonly known as passive smoking, consists of both sidestream smoke emitted from the burning tip of a cigarette and mainstream smoke, which is inhaled, filtered, and exhaled by the smoker. Recent studies suggest that younger children are more susceptible to the adverse effects of ETS exposure than adults or older children. In addition, less educated and lower income groups are at the greatest risk for smoking and ETS exposure. Various forms of evaluation will be used, including formative, process, and outcome methods (Beurden, 1998). Formative evaluation will include a review of the literature on the CHA model and its effectiveness in providing services to hard-to-reach communities. Process evaluation will include an assessment of how CHAs implemented behavioral contracts in a larger ETS intervention study. Outcomes measures will be used as a direct measure of CHA-delivered intervention success, and will include parent-reported ETS exposure to the child as well as the children’s hair nicotine and cotinine concentration, measured at baseline and immediately postintervention. The proposed evaluation will provide information about intervention implementation and the primary outcome changes in the area of ETS reduction in Latino homes. Findings can be used to plan, enhance, and develop future programs. Because the evaluation is limited to existing data, the main risk to participants is breach of confidentiality. To minimize the risk of disclosing private information, identification numbers will be used in lieu of participant names.
