Using marketing automation to modernize data collection in the California Teachers Study cohort.
CANCER EPIDEMIOLOGY BIOMARKERS & PREVENTION(2020)
摘要
Background: Like other cancer epidemiologic cohorts, the California Teachers Study (CTS) has experienced declining participation to follow-up questionnaires; neither the reasons for these declines nor the steps that could be taken to mitigate these trends are fully understood. Methods: The CTS offered their 6th study questionnaire (Q6) in the fall of 2017 using an integrated, online system. The team delivered a Web and mobile-adaptive questionnaire to 45,239 participants via e-mail using marketing automation technology. The study's integrated platform captured data on recruitment activities that may influence overall response, including the date and time invitations and reminders were e-mailed and the date and time questionnaires were started and submitted. Results: The overall response rate was 43%. Participants ages 65 to 69 were 25% more likely to participate than their younger counterparts (OR 125; 95% Cl, 1,18-1.32) and nonwhite participants were 28% less likely to participate than non Hispanic white cohort members (OR 0.72; 95% Cl, 0.68-0.76). Previous questionnaire participation wa-s strongly associated with re-spouse (OR 6.07; 95% CI, 5.50-6.70). Invitations sent after 2 pm had the highest response (OR 1.75; 95% CI, 1.65-1.84), as did invitations sent on Saturdays (OR 1.48; 95% CI, 1,36-1,60), Conclusions: An integrated system that captures paradata about questionnaire recruitment and response can enable studies to quantify the engagement patterns and communication desires of cohort members. Impact: As cohorts continue to collect scientific data, it is imperative to collect and analyze information on how participants engage with the study.
