Component Description

A nine-item depression screening instrument, the Patient Health Questionnaire (Kroenke and Spitzer, 2002; Kroenke et al., 2001) was administered to determine the frequency of depression symptoms over the past 2 weeks. A follow-up question assessed the overall impairment of the 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. The instrument incorporates DSM-IV depression diagnostic criteria (Spitzer et al.1999). The variable prefix is DPQ.

Eligible Sample

Mobile Examination Center (MEC) participants 12 years and older were eligible; only data from participants aged 12 to 17 are included in this Research Data Center file. Participants requiring a proxy were not eligible because of the sensitive nature of the questions.

Interview Setting and Mode of Administration

The questions were asked at the MEC, by trained interviewers, using the Computer-Assisted Personal Interview (CAPI) system as part of the MEC interview. Proxy respondents were not permitted for this section.

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 be assessed using pre-defined cut-points (see References).

Data for adults aged 12 years and older are available as an NHANES public release data file (DPQ_H).

The NHANES full sample 2-Year MEC Exam Weights (WTMEC2YR) should be used to analyze the 2013-2014.

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.
