Remote Biochemical Verification of Smoking Abstinence via Mobile-Phone Video Call

Abstract

Methods: Korean American women were recruited into a pilot smoking cessation study by advertising the study in online Korean American women’s communities and offline Korean ethnic newspapers. Smoking abstinence was based on a combination of self-report and salivary cotinine test at post-quit 3-month follow-up. Those who self-reported smoking abstinence were invited to conduct a homebased salivary cotinine test using a NicAlert test strip. Research staff monitored the whole process of the test via a mobile-phone video call and read the result when it was ready.
