Measuring Poly-tobacco Product Use with Ecological Momentary Assessment
Objectives: Poly-tobacco product use is common among tobacco users, but it is challenging to assess patterns of use in real-life contexts. The objective of this study is to determine whether intensive longitudinal methods are feasible for assessing concurrent use of multiple tobacco products. Methods: Overall, 28 participants completed a baseline questionnaire and 7 days of ecological momentary assessment data collection, including end-of-day, random, and real-time reporting. Results: When estimating use of cigarettes, vaping products, and other products individually, there were moderate correlations between baseline questionnaire estimates, end-of-day estimates, and random estimates (ρ = 0.379-0.640); however, daily totals of all products combined were poorly correlated (ρ = 0.198-0.461). Baseline questionnaire estimates were higher than random estimates for each product (median difference 1.5-7.0 products per day). End-of-day estimates were more consistent with the baseline questionnaire. There was low compliance with real-time product use reports. Conclusions: Random or daily reporting are feasible for poly- tobacco use assessment, but methods are needed to reconcile differences in estimates. Accurate measurement of poly-tobacco product use is needed to assess health impacts and inform policy.

More about this publication?
- Tobacco Regulatory Science (Electronic ISSN 2333-9748) is a rigorously peer-reviewed online scientific journal for the dissemination of research relevant to the regulation of tobacco products. The journal content includes a broad array of research domains, including chemistry, biology, behavior, community, and population-level surveillance and epidemiology, as well as knowledge syntheses (eg, meta-analyses or state-of-the-art reviews) and analytic modeling. All articles describe the policy relevance of the research outcomes. Given the global nature of tobacco regulation, particularly as a result of international and national policies, Tobacco Regulatory Science publishes high quality research that is relevant to global regulatory needs and requirements. Tobacco Regulatory Science is published electronically 6 times per year.
