The health care industry has continued its efforts to promote health and prevent disease among elderly populations. In this book, however, the authors argue that simple health promotion and disease prevention are not enough to address the many challenges of aging-whether it entails being physically frail, living with dementia, or approaching death. Instead, the unique focus of this groundbreaking text centers on maximizing function and well-being for the elderly. This book promotes the development and maintenance of optimal physical, mental, and social functioning, irrespective of acquired dis

Background U.S.-focused studies have reported decreasing dementia prevalence in recent decades, but have not yet focused on the implications of the COVID-19 pandemic for trends.
Methods We use the 2011-2021 National Health and Aging Trends Study (N=48,065) to examine dementia prevalence, incidence and mortality trends among adults ages 72 and older, and the contribution to prevalence trends of changes in the distribution of characteristics of the older population ("compositional shifts") during the full and pre-pandemic periods. To minimize classification error, individuals must meet dementia criteria for two consecutive rounds.
Results The prevalence of probable dementia declined from 11.9% in 2011 to 9.2% in 2019 and 8.2% in 2021 (3.1% average annual decline). Declines over the 2011-2021 period were concentrated among those ages 80-89 and non-Hispanic White individuals. Declines in dementia incidence were stronger for the 2011-2021 period than for the pre-pandemic period while mortality among those with dementia rose sharply with the onset of the COVID-19 pandemic. Shifts in the composition of the older population accounted for a smaller fraction of the decline over the full period (28%) than over the pre-pandemic period (45%).
Conclusions Declines in dementia prevalence continued into years marked by onset of the COVID-19 pandemic, along with declines in incidence and sharp increases in mortality among those with dementia. However, declines are no longer largely attributable to compositional changes in the older population. Continued tracking of dementia prevalence, incidence and mortality among those with and without dementia is needed to understand long-run consequences of the pandemic.
Abstract Adaptive survey designs are increasingly used by survey practitioners to counteract ongoing declines in household survey response rates and manage rising fieldwork costs. This paper reports findings from an evaluation of an early-bird incentive (EBI) experiment targeting high-effort respondents who participate in the 2019 wave of the US Panel Study of Income Dynamics. We identified a subgroup of high-effort respondents at risk of nonresponse based on their prior wave fieldwork effort and randomized them to a treatment offering an extra time-delimited monetary incentive for completing their interview within the first month of data collection (treatment group; N = 800) or the standard study incentive (control group; N = 400). In recent waves, we have found that the costs of the protracted fieldwork needed to complete interviews with high-effort cases in the form of interviewer contact attempts plus an increased incentive near the close of data collection are extremely high. By incentivizing early participation and reducing the number of interviewer contact attempts and fieldwork days to complete the interview, our goal was to manage both nonresponse and survey costs. We found that the EBI treatment increased response rates and reduced fieldwork effort and costs compared to a control group. We review several key findings and limitations, discuss their implications, and identify the next steps for future research.
The Panel Study of Income Dynamics (PSID) is the world's longest running household panel survey. Since it began in 1968, it has collected data on the same families and their descendants, making it an essential part of America's data infrastructure for empirically based social science research. The PSID arose from the War on Poverty as a tool for evaluating poverty dynamics, and this year (2018) marks 50 years of data collection. Because of its long history and distinctive design of following adult children as they form their own households, the PSID is uniquely positioned to address emerging social and behavioral research questions and related policy issues. This overview presents the design and structural aspects and its evolution over the past 50 years, the successes of the current survey, possible future directions, and the value of using the PSID to understand the challenges facing American families.
The authors examined associations between marital quality and both general life satisfaction and experienced (momentary) well‐being among older husbands and wives, the relative importance of own versus spouse's marital appraisals for well‐being, and the extent to which the association between own marital appraisals and well‐being is moderated by spouse's appraisals. Data are from the 2009 Disability and Use of Time daily diary supplement to the Panel Study of Income Dynamics (N = 722). One's own marital satisfaction is a sizable and significant correlate of life satisfaction and momentary happiness; associations do not differ significantly by gender. The authors did not find a significant association between spouse's marital appraisals and own well‐being. However, the association between husband's marital quality and life satisfaction is buoyed when his wife also reports a happy marriage, yet flattened when his wife reports low marital quality. Implications for understanding marital dynamics and well‐being in later life are discussed.
Abstract Maintenance of visual and auditory function is important for preventing the onset of activity limitations and preserving quality of life in later life. To date, national panel studies focused on health and aging have mostly collected subjective (self-reported) measures of visual and auditory function. The National Health and Aging Trends Study (NHATS), a study of Medicare beneficiaries ages sixty-five and older, recently developed a protocol for measuring objective visual and auditory function for its annual, in-home data collection conducted by trained interviewers. The protocol includes three vision tests—distance and near acuity and contrast sensitivity—and one hearing test—pure-tone audiometry—conducted using a tablet platform with results recorded in a scannable booklet. To identify operational issues and evaluate data quality for the proposed set of vision and hearing tests, NHATS incorporated a pilot study into its 2019 round (N = 417 participants and N = 9 interviewers). Using these pilot study data, the objectives of this paper are to: (1) describe the NHATS protocols to collect objective measures of visual and auditory function; (2) evaluate the quality of the data collected; and (3) assess whether results are influenced by interviewers. We found that respondents were highly likely to participate, with cooperation rates for each test about 90 percent. Data were high quality, with low rates of missingness, test results significantly associated with age and self-reported items, and percentages with poor vision or hearing consistent with prior population-based studies. Objective measures were more likely than self-reports to classify participants as having visual and auditory impairments and had stronger relationships with demographic correlates. Interviewer effects were small and not statistically significant in this small sample. Results of this study have demonstrated that objective visual and auditory functioning can be successfully incorporated into an interviewer-administered home-based protocol.
