The question for SATISFIED is one of a series included in the National Health Interview Survey (NHIS) as part of the Healthy People 2010 initiative. One goal of this initiative is to "promote the health of people with disabilities, prevent secondary conditions, and eliminate disparities between people with and without disabilities in the U.S. population." More specifically, U.S. Department of Health and Human Services, Healthy People 2010, V. II, Objectives for Improving Health, articulated the following goal: "Increase the proportion of adults with disabilities reporting satisfaction with life" (i.e., to achieve parity with adults without disabilities).

Healthy People 2010, V. I, Disability and Secondary Conditions elaborates on the meaning of "satisfaction with life" as follows:

Similar to the life satisfaction measure included in the 2001 NHIS, measures of life satisfaction are included in the 2021 NHIS as a means of estimating and tracking progress towards the Healthy People 2030 goal of increasing general adult well-being, and life satisfaction as an important component of general well-being, in the US population. On p. 83, the 2021 NHIS Survey Description states:

In addition to SATISFIED, a second quality of life variable (SATSCORE) was included in the 2021 survey. SATSCORE asks respondents to quantify their quality of life on a scale from 0 ("very dissatisfied") to 10 ("very satisfied"). Both questions were fielded intentionally for methodological reasons; analysts will compare respondents' answers against each other to determine how the categorical responses align with the numeric score on the 11-point scale.

In the first quarter of 2021, SATSCORE was asked near the beginning of the survey (section LS1) and SATISFIED near the end (LS2). In the second quarter, an experiment was introduced to randomly rotate the order of the two questions in the Sample Adult survey. The variable SATFLAG records which question was asked first in each interview. Users should note that both SATISFIED and SATSCORE reflect the combined responses for all four quarters of 2021, regardless of the order of each question across the LS1 and LS2 sections. As a result, the number of "not ascertained" responses (code 8) may appear inflated due to drop-offs when each variable was asked in the LS2 section.

Other related variables that track emotional and social support in the 2021-2022 NHIS:

• EMOSUPPORT: How often get emotional support

• SUPPORTCOMM: Have an adult that makes a positive or meaningful difference in life (sample child only)

• SATISFIEDSCALE: Life satisfaction using numerical scale (sample child only)
