Web and paper survey mode patterns and preferences, Health & Employment Survey, World Trade Center Health Registry

Abstract

This study described patterns of response versus nonresponse, earlier versus later response, and paper versus web response to the 2017–2018 Health & Employment Survey (HES). We predicted odds of responding to the survey based on demographic factors and examined impact of multiple email reminders on response volume. The overall completion rate was 65%. The likelihood of responding to HES was more than doubled when the web survey was an option. Most web surveys were received during the first two months of data collection compared with less than one-third of paper surveys. Multiple email reminders resulted in increased responses. To offer mode options to all, more efforts should be made on collecting valid email addresses.
