Abstract: This report summarizes findings from cognitive testing of the 2016 National Health Interview Survey (NHIS) Diabetes Primary Prevention Questions. The main objective of the NHIS is to monitor the health of the United States population through the collection and analysis of data on a broad range of health topics. The 2016 Diabetes Primary Prevention questions are designed to address the following objectives: • Assess the levels of screening, testing, and detection of prediabetes and diabetes currently underway in the U.S. • Examine levels of selected diabetes risk factors • Examine levels of referral, uptake, and participation in structured diabetes prevention programs, community weight loss and exercise programs • Identify adults with Type 1 diabetes among those with diagnosed diabetes Cognitive testing was conducted to ascertain how the diabetes questions are able to meet these objectives. This evaluation is based on 45 cognitive interviews that were conducted by the Center for Question Design and Evaluation Research (CQDER) at the National Center for Health Statistics (NCHS), between February and April of 2015. Cognitive interviewing is a qualitative question evaluation method used to assess the construct validity of survey questions (Willis 2005; Miller 2011). The following sections of this report include an overview of cognitive interviewing methodology, a summary of key findings, and a question by question analysis.
