Sexual orientation in the 2013 National Health Interview Survey : a quality assessment

Objective: This report presents a set of quality analyses of sexual orientation data collected in the 2013 National Health Interview Survey (NHIS). NHIS sexual orientation estimates are compared with those from the National Survey of Family Growth (NSFG) and the National Health and Nutrition Examination Survey (NHANES). Selected health outcomes by sexual orientation are compared between NHIS and NSFG. Assessments of item nonresponse, item response times, and responses to follow-up questions to the sexual orientation question are also presented.Methods: NHIS is a multipurpose health survey conducted continuously throughout the year by the Centers for Disease Control and Prevention\u2019s National Center for Health Statistics. Analyses in this report were based on NHIS data collected in 2013 from 34,557 adults aged 18 and over. Sampling weights were used to produce national estimates that are representative of the civilian noninstitutionalized U.S. adult population. Data from the 2006\u20132010 NSFG and 2009\u20132012 NHANES were used for the comparisons.Results: Based on the 2013 NHIS data, 96.6% of adults identified as straight, 1.6% identified as gay/lesbian, and 0.7% identified as bisexual. The remaining 1.1% of adults identified as \u2018\u2018something else,\u2019\u2019 stated \u2018\u2018I don\u2019t know the answer,\u2019\u2019 or refused to answer. Responses to follow-up questions suggest that the sexual orientation question is producing little classification error. In addition, largely similar patterns of association between sexual orientation and health were observed for NHIS and NSFG. Analyses of item nonresponse rates revealed few data quality issues, although item response times suggest possible shortcutting of the question and comprehension problems for select respondents.Suggested citation: Dahlhamer JM, Galinsky AM, Joestl SS, Ward BW.
