The QDRL was the first cognitive research lab in the federal statistical system. QDRL staff have developed software to facilitate in the analysis of cognitive interviewing data; this includes Q-Bank, Q-Notes, and Q-Video. These products allow the QDRL to increase both productivity and work quality. 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 , is a database consisting of evaluated questions from Federal surveys and links each question to the scientific report that evaluated the survey question. Q-Bank is intended to help users of survey data interpret the survey questions on which the data are based and understand the potential errors that might be associated with these questions.


Q-Notes , is a software program that supports the structured collection and analysis of cognitive interview data. Hence, it serves as an audit trail tracing each finding to the original source. The video of the actual interview is embedded within the application so that the findings can truly be traced to the original source.


Q-Video , is a digitized video/audio application that captures, stores, and indexes the video and audio of a cognitive interview at the questionnaire level in a digitized database for the purpose of searching individual questions and conducting analysis.
