Codes and Frequencies
For sample children ages 5-17 and sample adults, WORFREQ reports how often they felt worried, nervous or anxious. Prior to 2019, WORFREQ was not asked of sample children.
Changes in survey design (e.g., quarters in which the supplement was collected) may affect raw frequencies, but do not affect comparability of the variable. Beginning in 2018, this item was included on the sample adult questionnaire. As always, users should employ the prescribed IPUMS NHIS weights.
In 2010, this item was collected for sample adults who completed the Quality of Life supplement (administered to approximately a quarter of sample adults). In 2011-2017, this item was collected for sample adults who completed the Adult Functioning and Disability supplement (administered to a subset of sample adults). Beginning in 2018, this item was included on the sample adult questionnaire and, beginning in 2019, WORFREQ was also asked of sample children ages 5-17.
Additionally, while the basic meaning of this variable is completely comparable over time, major questionnaire changes introduced in 2019 may affect comparability with earlier years. The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
