Parent counseling reduced children's ETS exposure in previous studies. This study will determine if interventions directed to preteens alone can reduce ETS exposure. The original pilot study showed that counseling reduced preteen's ETS exposure. New analyses showed that counseling reduced exposure to preteens in the NIH asthma study. A third pilot study showed that counseling plus feedback and incentives reduced preteens' ETS exposure. Based on these results, the number of counseling sessions were decreased to 10, inclusion criteria were liberalized, and recruitment sources were added to assure feasibility.
