Component Description

The Dermatology questionnaire section (DEQ) provides personal interview data on psoriasis, sun exposure and sun protective behavior.

Eligible Sample

The target group for this questionnaire section is participants aged 20-59 years.

Interview Setting and Mode of Administration

This questionnaire was done before the physical examination, in the home, using the Computer-Assisted Personal Interviewing-CAPI (interviewer administered) system.

Quality Assurance & Quality Control

The CAPI system is programmed with built-in consistency checks to reduce data entry errors. CAPI also uses online help screens to assist interviewers in defining key terms used in the questionnaire.

Data Processing and Editing

Frequency counts were verified during the preparation of the file.

Analytic Notes

The following items were dropped from the 2005-2006 data set:
DEQ011, DEQ021, DEQ041, DEQ051, DEQ061, DEQ071, DEQ083 a-I and DEQ083u.

Responses to question DEQ038Q, “How many times in the past year have you had a sunburn?”, with values of 20 or more, were combined into one category. The variable was renamed DEQ038D.

Analysts should be aware that some questions (such as DEQ.053 – ever told you had psoriasis) have very few responses for some categories. Even with two years of data collection, there may not be sufficient sample size for such variables to be analytically useful. In these cases, it may be necessary to combine more than two years of data to conduct analysis.

Although these data were collected as part of the household questionnaire, if they are merged with the MEC exam data, exam sample weights should be used for the analyses.

Please refer to the Analytic Guidelines for further details on the use of sample weights and other analytic issues. The Analytic Guidelines are available on the NHANES website.
