Research and Projects
Dr. Rodgers has done extensive research on the quality of survey data: for example, the accuracy of responses to survey questions as assessed by comparisons to external data sources, and the reliability and construct validity of the responses to a much wider variety of questions. His emphasis in that research has been on surveys with elderly populations.
