Comparison of Direct to Consumer Delivery Models for Hearing Devices, Illinois and Texas, 2020-2025 (ICPSR 39653)

Released/updated on: 2026-07-09

Geographic coverage: United States, Illinois, Texas

Time period: 2020-01-01--2025-01-01

In an effort to make hearing aids more affordable and accessible to U.S. adults with hearing difficulty, the Food and Drug Administration (FDA) empowered these adults to self-fit over-the-counter (OTC) hearing aids. The effectiveness of two self-fit methods, Consumer Decides (CD) and Efficient Fitting (EF), was hypothesized to be non-inferior to the professional-fit method, (Audiology Based, AB). This was evaluated for both short-term (6 weeks post-fit) and long-term (6 months post-fit) outcomes.

Health and Retirement Study (HRS) (ICPSR 6854)

Released/updated on: 2006-04-06

Geographic coverage: United States

The University of Michigan Health and Retirement Study (HRS) is a longitudinal panel study that surveys a representative sample of approximately 20,000 people in America, supported by the National Institute on Aging and the Social Security Administration.

The HRS aims to provide multidisciplinary data that researchers can use to address important questions about the challenges and opportunities of aging. The HRS includes the "original" HRS and the Asset and Health Dynamics Among the Oldest-Old (AHEAD) study. These studies were merged in 1998 and now represent the United States population over age 50. Two new cohorts were added in 1998: the Children of the Depression (born 1924-1930) and the War Babies (1942-1947). A fourth cohort, the Early Baby Boomers (1948-1953), was added in 2004; a fifth cohort, the Mid Baby Boomers (1954-1959), was added in 2010; and in 2016, the Late Baby Boomers cohort (1960-1965) became the sixth.

Questionnaire topics include physical and cognitive functioning, retirement plans, family structure and transfers, demographic characteristics, housing, employment status, income, disability, health insurance, pension plans, job history, and attitudes, preferences, and expectations for the future. The survey data are linked with administrative records from the Employer Pension Study (1993 and 1999), National Death Index, Social Security Administration earnings and projected benefits data and W-2 self-employment data, and Medicare files.

The basic purpose of the Health Interview Survey (HIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. The 1977 Hearing Supplement provides variables from the core Person File (see HEALTH INTERVIEW SURVEY, 1977 [ICPSR 7839]) including sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limits on activity. The variables unique to this supplement include information on hearing problems, use of aids, hearing acuity, chronic and acute conditions, restriction of activities, medical treatment, surgery, hospitalization, and medicine.

Swedish Adoption/Twin Study on Aging (SATSA), 1984, 1987, 1990, 1993, 2004, 2007, and 2010 (ICPSR 3843)

Released/updated on: 2015-05-13

Geographic coverage: Sweden, Global

Time period: 1984-01-01--2010-01-01

The Swedish Adoption/Twin Study on Aging (SATSA) was designed to study the origins of individual differences in aging and the environmental and genetic factors that are involved. SATSA began in 1984, and six additional waves were conducted in 1987, 1990, 1993, 2004, 2007, and 2010. The questionnaire was initially sent to all twins from the Swedish Twin Registry who were separated at an early age and raised apart; the survey was also administered to a control sample of twins who were raised together. The respondents were surveyed on items that included health status, how they were raised, work environment, alcohol consumption, and dietary and smoking habits, as well as questions about personality and attitudes; this information comprised the first component. The second component was collected from a subsample composed of 150 pairs of twins raised apart and 150 pairs of twins raised together. This subsample participated in seven waves of in-person testing, which included a health examination, structured interviews, and tests on functional capacity, cognitive abilities, and memory. The data are represented according to questionnaire and time number, and correspond to each wave/year: Questionnaire 1 and In-Person Testing Time 1 were in 1984; Questionnaire 2 and In-Person Testing Time 2 were in 1987; Questionnaire 3 and In-Person Testing Time 3 were in 1990; Questionnaire 4 and In-Person Testing Time 4 were in 1993; Questionnaire 5 was in 2003; In-Person Testing Time 5 was in 2004; Questionnaire 6 and In-Person Testing Time 6 were in 2007; In-Person Testing Time 7 was in 2010. The Administrative and Cognitive datasets include data from all years/waves. The Smell Survey dataset only includes data from 1990. No years were specified for the Contact measures and Separation measures datasets. Demographic and background information includes age, sex, education, family history, household composition and employment.
