Assessing and adjusting for non-response in the Millennium Cohort Family Study.

Background: In conducting population-based surveys, it is important to thoroughly examine and adjust for potential non-response bias to improve the representativeness of the sample prior to conducting analyses of the data and reporting findings. This paper examines factors contributing to second stage survey non-response during the baseline data collection for the Millennium Cohort Family Study, a large longitudinal study of US service members and their spouses from all branches of the military.

Methods: Multivariate logistic regression analysis was used to develop a comprehensive response propensity model.
