We sought a sample of pregnant smokers aged 18 years and older living in the United States for a cross-sectional survey-based study of decision-making styles and preferences for incentive-based smoking cessation programs during pregnancy. The study was approved by the institutional review board of the University of Pennsylvania. Study respondents were first asked to complete a 6-question screener created on the Qualtrics Web-based survey platform to determine eligibility. Eligible respondents who provided informed consent then completed a 93-question survey about pregnancy history, smoking history, decision-making style, and smoking cessation program preferences (see Multimedia Appendix 1 for a sample of selected questions). Participants who did not consent were not allowed to continue onto the second survey. The recruitment period ran from July 6 to July 27, 2016. In total, 308 eligible respondents completed the survey. We evaluated platforms based off of two yields: eligibility yield, defined as the percentage of participants who met the inclusion criteria out of the number of total number of respondents, and quality yield, defined as the percentage of eligible participants who correctly and appropriately answered attention and quality checks embedded throughout the survey.
