Health Indicator Report of Ability To Do Usual Activities in the past 30 Days
Self-rated health (SRH) has been collected for many years on National Center for Health Statistics surveys and since 1993 on the state-based Behavioral Risk Factor Surveillance System (BRFSS). Ability to perform usual activities is one indicator of SRH. SRH is an independent predictor of important health outcomes including mortality, morbidity, and functional status.

Data Interpretation IssuesQuestion Text: "Number of days during past 30 days in which usual activities could be conducted?" Data from the survey should be considered representative of all non-institutionalized adults in households with telephones. Data were collected using a random sample of all possible telephone numbers. Prior to analysis, data were weighted to represent the population distribution of adults by sex, age group, and area of residence. As with all surveys, some error results from nonresponse (e.g., refusal to participate in the survey or to answer specific questions), and measurement (e.g., social desirability or recall bias). Error was minimized by use of strict calling protocols (up to 15 calls were made to reach each household), good questionnaire design, standardization of interviewer behavior, interviewer training, and frequent, on-site interviewer monitoring and supervision.
DefinitionAverage number of days adults aged 18 years and older reported ability to do usual activities during the past 30 days.
NumeratorNumber of days each survey respondent reported being able to conduct usual activities.
DenominatorTotal number of survey respondents excluding those with missing, 'Don't know/Not sure' and 'Refused' responses.
Other ObjectivesHealthy New Jersey 2010 Objective 1-4: Increase days able to do usual activities during the past 30 days, due to good physical or mental health, among persons 18 and over to 28.7 for all adults 18+.
How Are We Doing?Overall, New Jersey adults ages 18 and older report the mean number of ability days (able to conduct usual activities) to be 28 within the past 30 days. In 2010, Asians reported the highest number of ability days (29.0) compared to Whites (28), Blacks (27.7) and Hispanics (27.7).
