These questions are from the Patient Health Questionnaire (PHQ), a version of the Prime-MD diagnostic instrument. They are a self-reported assessment based on the nine DSM-IV signs and symptoms for depression. Referred to as the Depression Screener Questionnaire (DPQ) in NHANES, the nine symptom questions are scored from "0" (not at all) to "3" (nearly every day). An additional follow-up question assesses the overall impairment of the depressive symptoms. Used most often in primary care settings, the PHQ has been shown to be a reliable and valid tool for the diagnosis of depression.
The eligible sample is mobile exam center (MEC) participants 12 years and older.
