 The long-range goal of my research is to test PED-based cessation interventions that are readily translated into practice in large, multi-center trials. However, before this can occur, preliminary data are needed, including analyses of: 1 the types of cessation intervention components that low-income parental smokers regard as essential to their cessation success; 2 perceived organizational barriers to the sustainability of the intervention after the study period ends which will impede translation into practice; 3 factors associated with parental cessation outcomes such as the presence of an acute SHSe-related chief complaint in the child; and 4 the effect size of the intervention. This data will be used to develop a parental cessation intervention that is tailored to low-income parents who are likely to quit. Data from the proposed project will be used in a RO1 application to test the efficacy of this cessation intervention in a large, multi-center randomized trial.
