title: A comparative evaluation of self-report and biological measures of cigarette use in nondaily smokers.
abstract: A large subset of individuals who smoke cigarettes do not smoke regularly, but the assessments used to collect data on cigarette consumption in nondaily smokers have not been rigorously evaluated. The current study examined several self-report and biomarker approaches to the assessment of cigarette use in a sample of nondaily smokers (n = 176). Participants were randomly assigned to a daily monitoring condition (n = 89), requiring a daily report of the number of cigarettes smoked in the previous 24 hours, or a no monitoring condition (n = 87). Number of cigarettes smoked over the first 28 days of the study was assessed using 2 quantity frequency measures, a graduated frequency measure, and a timeline follow back (TLFB) interview at the Session 5 study visit. Hair nicotine (NIC), hair cotinine (COT), and expired-air carbon monoxide (CO) were collected from each participant. Total cigarettes reported via daily report were strongly correlated with all Session 5 measures of total cigarettes, but were most strongly associated with TLFB total cigarettes. Collapsed CO across 5 sessions was the biomarker most strongly correlated with daily report total cigarettes. The results support the use of daily report and TLFB methods of assessing cigarette use in nondaily smokers. Results also support the use of CO as appropriate biological markers of exposure in nondaily smokers, and point to some limitations in the use of hair biomarkers in this population.
