Despite high rates of cigarette use, little attention has been paid to screening and cessation services for youth in foster care. Study aims were to test the feasibility, acceptability, and preliminary efficacy of a technology-based smoking cessation intervention. Study enrollment, satisfaction, and engagement were high in the intervention arm, where readiness to change also significantly increased over time. Intervention and control participants significantly reduced cigarette use at 6-month follow up, though groups did not differ. Technology-based interventions appear to be attractive and offer a potentially scalable link to health care that this vulnerable population may not otherwise seek.
