Codes and Frequencies
For sample children ages 2-4, UNDRSTYOU indicates whether the sample child has difficulty understanding the survey respondent. UNDRSTYOU is part of the Washington Group Composite Disability Indicator for children ages 2-4.
In 2019, functioning and disability measures included on the NHIS questionnaire were modified to align with validated, internationally-comparable disability measures developed by the Washington Group on Disability Statistics (WG). For more information about the WG initiative, other WG functioning and disability measures included on the NHIS questionnaire, and guidance for researchers about how to use the WG measures in analyses, please see our user note on the Washington Group Disability Measures.
