Mission Statement

The Collaborating Center for Questionnaire Design and Evaluation Research (CCQDER) conducts question evaluation and development studies for the National Center for Health Statistics, the CDC, and other HHS surveys. The primary method of evaluation is cognitive interviewing, although a range of other qualitative and quantitative methods, including focus groups, ethnographic methodology, and experimental web surveys, are also used. Question evaluation studies seek to identify patterns of interpretation, various forms of response error, and problems of question comparability across respondent groups.


  • Question development and Evaluation: CCQDER conducts cognitive interviewing studies and other pretest methodologies in support of evaluating and developing reliable surveys for NCHS and external agencies.
  • Methodological Research: CCQDER researches and refines question evaluation methods while also working to better understand the question response process and survey response error.
  • Development of Technology Products: CCQDER develops software to improve qualitative data collection, analysis, and to increase the accessibility and transparency of question evaluation studies.
