Methodology
The National Health Interview Survey (NHIS) is a household survey of children and adults. Through personal interviews, NHIS collects information on a broad range of health topics, including health insurance, doctor's office visits, physical activity and other health behaviors. The information collected is used to track the health status of U.S. populations, healthcare access, and progress toward achieving national health objectives. Conducted annually, NHIS is sponsored by the National Center for Health Statistics. An adult is considered to have symptoms of psychological distress if the adult or an adult proxy responds "yes" to "ALL of the time" or "MOST of the time" to any of the numerator questions for adults. The six adult questions reflect the Kessler 6 (K6) scale, which is used internationally to assess feelings of sadness, restlessness, hopelessness, nervousness, worthlessness, and the sense that everything is an effort. Positive responses increase the score. This scale has the sensitivity and specificity to effectively discriminate between cases and non-cases of mood disorders, but it cannot define which specific disorder (such as clinical depression, generalized anxiety disorder) that any given respondent to the survey may have. With total scores ranging from 0 to 24, a standard cutoff score of 13 or higher on the K6 has been used to identify persons with nonspecific serious psychological distress.
