Questionnaire Design Research Laboratory



The QDRL was the first cognitive research lab within the federal statistical system. The QDRL and NCHS continue to invest in and develop technology products that enhance questionnaire development and evaluation. These products allow the QDRL to increase both productivity and the quality of work. They also provide transparency and accountability of our research processes. This transparency allows us to continually assess, review and improve our methodology and practices.



Q-Bank , a public resource containing all QDRL question evaluation reports along with reports contributed by numerous federal agencies. Q-Bank provides users with a centralized location to access the knowledge gained from question evaluation projects, along with information to learn about the field of Question Evaluation.



Q-Notes , a software packages facilitating the management of cognitive interview projects and the analysis of cognitive interview data.



Q-Video, a video management system that archive interview recordings, making them accessible to research staff

  • Allows for audio and video recording of interviews at the NCHS headquarters in Hyattsville, MD.
  • Capability to conduct and record interviews in the field as required by projects.
  • Provides automatic transcription functionality
  • Q-Notes Plus, an enhanced version of Q-Notes software which includes the videos and clips from the recorded cognitive interviews, allowing for an more complete analysis
