2015 Stress in America™

Methodology

The 2015 Stress in America™ survey was conducted online within the United States by Harris Poll on behalf of the American Psychological Association (APA) between Aug. 3 and 31, 2015, among 3,361 adults aged 18+ who reside in the U.S. Interviews were conducted in English (n=2972), Spanish (n=306), Chinese (n=66), Vietnamese (n=9) and Korean (n=8). Respondents for this survey were selected from among those who have agreed to participate in Harris Poll surveys. Data are weighted to reflect their proportions in the population. Weighting variables included age, gender, race/ethnicity, education, region and household income. Propensity score weighting also was used to adjust for respondents’ propensity to be online. In addition to the demographic variables listed, data from Hispanic respondents were weighted for acculturation, taking into account respondents’ household language as well as ability to read and speak in English and Spanish.

All sample surveys and polls, whether or not they use probability sampling, are subject to multiple sources of error, which are most often not possible to fully estimate and control, including sampling error, coverage error, error associated with nonresponse, error associated with question wording and response options, and post-survey weighting and adjustments. Therefore, Harris Poll avoids the words “margin of error,” as they are misleading. All that can be calculated are different possible sampling errors with different probabilities for unweighted, random samples with 100 percent response rates. These are only theoretical because no published polls — whether conducted by telephone or online — come close to the ideal probability sample given the sources of error previously noted. Because the sample is based on those who were invited and agreed to participate in an online research panel, no estimates of theoretical sampling error can be calculated.

Race/Ethnicity Definition

Harris Poll’s methods for asking about and categorizing race and ethnicity are in accordance with the approach taken by the U.S. Census Bureau which treats race and ethnicity as two separate and distinct categories, examined in two separate questions.1 Per the Census’ framework, ethnicity is categorized as either “Hispanic or Latino” or “not Hispanic or Latino.” Race comprises five categories: 1) White, 2) Black/African-American - referenced in the report as Black, 3) Asian, 4) Native American/Alaskan Native - referenced in the report as American Indian/Alaska Native (AI/AN), and 5) Hawaiian Native or other Pacific Islander. The Census further describes that the concept of race reflects self-identification by people according to the race or races with which they most closely identify and that people who report themselves as Hispanic can be of any race.

Using the framework described above and the questions below, if respondents identified as Hispanic in Q1, for the purposes of this research, they were included in the Hispanic subgroup regardless of their responses to the subsequent questions examining race. All other respondents were identified based solely on their answers to Q2. Very few indicated they were of mixed race or some other race. Those who did are included in the total sample, but have been excluded from the racial/ethnic analysis, as there were too few (1 percent of the total sample) to analyze separately.

Poverty Level Definition

The proportion of respondents in poverty was calculated based on the 2015 Federal Poverty Guidelines.2 The calculation takes into account annual household income, as well as the number of persons living in the household. For the purposes of this research, poverty was defined as being at or below 200 percent of the federal annual poverty guidelines. For example, a family of four is considered to be living in poverty if their annual household income is $48,500 or less.

Emotional Support Definition

Emotional support was defined using the question below from the National Health and Nutrition Examination Survey (NHANES). Respondents who said “yes” to the question below were categorized as having emotional support, and those who said “no” were categorized as not having emotional support. Those who said “I do not need help” were not included in analyses examining the impact of emotional support.

QUESTION TO DEFINE EMOTIONAL SUPPORT

Q: Is there someone you can ask for emotional support if you need it, such as talking over problems or helping you make a difficult decision?

  1. Yes
  2. No
  3. I don’t need help
Disability Definition

Disability was defined using the question below. Respondents who selected “yes, myself only” or “yes, both myself and someone else” for any of the four conditions listed were qualified as persons with a disability. Respondents who selected “yes, someone else only” or “no” were considered not to have a disability. Respondents who selected “decline to answer” were excluded from the classification.

QUESTION TO DEFINE DISABILITY

Q: Do you, or does anyone in your household, have any of the following conditions?

  1. Yes, myself only
  2. Yes, someone else only

QUESTIONS TO DEFINE LGBT

Q1: Are you…?

  1. Male
  2. Female
  3. Transgender

The survey measured two types of discrimination: 1) day-to-day, and 2) major forms of discrimination. The questions used in this survey were adapted from The Everyday Discrimination Scale3 and Major Experiences of Discrimination Scale.4 The percentage for “experiencing any discrimination” is reflective of the percentage who said they experienced the following:

  • At least one of the five day-to-day stressors “less than once a year” or more often (Q1); or
  • Ever experienced one of nine major forms of discrimination (Q2).

Similarly, the average number of discrimination experiences was calculated using the sum of the frequency rating of the five day-to-day stressors (Q1) and the sum of the nine major forms of discrimination (Q2). A respondent was categorized as having experienced discrimination if they indicated they experienced at least one day-to-day type of discrimination at least “less than once a year” or more often or at least one of the nine forms of major discrimination ever in their lives.

  4. A few times a month
  5. At least once a week
  6. Almost everyday
    1. You are treated with less courtesy or respect than other people.

    9. Have you ever been treated unfairly while using transportation (e.g., buses, taxis, trains, at an airport, etc.)? [Note: not from the Major Experiences of Discrimination Scale]

In order to confirm that the higher reported average stress levels noted for Hispanic Americans was not due to other demographic differences (i.e., age) between racial/ethnic subgroups, two additional analyses were conducted.

  1. All data were weighted to reflect the general profile of U.S. adults across races/ethnicities (i.e., racial/ethnic groups were not weighted separately to their own demographic targets).
  2. A linear regression.

The outcomes of these two analyses confirmed that Hispanic Americans have higher reported stress levels, on average, than other racial/ethnic groups. After applying the general profile weights to all racial/ethnic subgroups to make them the same demographically for age, gender, income and education, the overall stress level was still significantly higher for Hispanic Americans compared to White Americans, Black Americans, Asian Americans and the total sample. 

The linear regression was conducted using the overall stress rating (Q605) as the dependent variable, with gender, age, income and race/ethnicity as the independent variables. Variables that have a statistically significant linear relationship with stress are determined by significant values equal to or less than 0.05. The analysis revealed that being female, being younger, having a lower income and being Hispanic have significant impacts on overall reported stress level.
