Survey Design & Measurement Core

The Survey Design and Measurement Core assists with survey study design, questionnaire development, psychometrics, and instrument assessment. Our faculty are available to serve as co-investigators and aid in writing methodological sections of grant proposals and scientific manuscripts. We collaborate with SDBC statisticians to ensure seamless transition from data collection to statistical analysis, and work with the Qualitative team for mixed-method studies. Our services include:

  • Whole questionnaire design and pretesting, including visual layout, question ordering, instructions, and response format
  • Survey data collection protocols, contact methods, and selecting survey mode(s) to maximize response rates and data quality
