Similarities and Differences in Tobacco Control Research Findings From Convenience and Probability Samples.

ABSTRACT:

Background

Online convenience samples are a quick and low-cost way to study health behavior, but the comparability to findings from probability samples is not yet well understood.

Purpose

We sought to compare convenience and probability samples' findings for experiments, correlates, and prevalence in the context of tobacco control research.

Methods

Participants were a probability sample of 5,014 U.S. adults recruited by phone from September 2014 through May 2015 (cost ~U.S.$620,000) and an online convenience sample of 4,137 U.S. adults recruited through Amazon Mechanical Turk (MTurk) in December 2014 (cost ~U.S.$17,000). Participants completed a survey with experiments, measures of tobacco product use and demographic characteristics.
