DPQY_G

Component Description

Depression was measured using the Patient Health Questionnaire (PHQ-9), a nine-item screening instrument that asked questions about the frequency of symptoms of depression over the past 2 weeks. A final follow-up question assessed the overall impairment of the depressive symptoms. Response categories for the nine-item instrument "not at all," "several days," "more than half the days," and "nearly every day" were given a point ranging from 0 to 3.

Eligible Sample

Mobile examination center participants 12 years and older were eligible. No proxies were permitted to answer these questions. Only data from youths aged 12-17 years are included in this restricted data file. A public use data file DPQ_G is available for adults 18+ years.

Interview Setting and Mode of Administration

These questions were asked by trained interviewers in Spanish or English using the Computer-Assisted Personal Interviewing (CAPI) system during the MEC private interview.

Quality Assurance & Quality Control

The CAPI system is programmed with built-in consistency checks to reduce data entry errors.

Data Processing and Editing

Edits were made to ensure completeness, consistency and analytic usefulness of the data.

Analytic Notes

A total score is based on the sum of the points in each item ranging from 0 to 27. Major depression and depression severity can also be assessed.

The NHANES full sample 2-Year MEC Exam Weights (WTMEC2YR) should be used to analyze the 2011-2012.

Please refer to the NHANES Analytic Guidelines and the on-line NHANES Tutorial for further details on the use of sample weights and other analytic issues.
