Purpose of the study:

The primary aim of this investigation was to determine whether caregiver confidence in their care recipients’ functional capabilities predicts changes in the performance of activities of daily living (ADL) among elderly home care recipients. A secondary aim was to explore how caregiver confidence and care recipient functional self-efficacy jointly influence changes in ADL performance over time.

Design and Methods:

The sample included 5,138 elderly recipients of home and community-based long-term care in Michigan. ADL performance was assessed multiple times over a 2-year period. Caregiver confidence was measured at baseline with a single item. Multilevel modeling was used to estimate the effect of caregiver confidence on changes in ADL performance over time, controlling for baseline self-efficacy, ADL performance, and other factors that might confound the relationship. Based on caregiver confidence and elder self-efficacy, we created 4 groups of elder caregiver dyads to explore the combined effect of caregiver and elder confidence on change in ADL performance.

Results:

Elders whose caregivers were confident in their capacity for greater functional independence experienced greater improvement in ADL performance than those whose caregivers were not confident. Elders in dyads in which both members expressed confidence experienced more improvement in ADL performance than those in dyads in which either one or both members lacked confidence.

Implications:

Interventions to strengthen caregivers’ confidence in their care recipients’ functional capabilities may slow functional losses among home care elders. Additional research is needed to confirm these findings and identify the factors that influence caregiver confidence.

Objectives.

To estimate the prevalence of successful aging in the United States, with the broad aim of contributing to the dialogue on Rowe and Kahn’s concept of successful aging.

Methods.

Using data from the Health and Retirement Study, the prevalence of successful aging was calculated for adults aged 65 years and older at four time points: 1998, 2000, 2002, and 2004. Successful aging was operationalized in accordance with Rowe and Kahn’s definition, which encompasses disease and disability, cognitive and physical functioning, social connections, and productive activities.

Results.

No greater than 11.9% of older adults were aging “successfully” in any year. The adjusted odds of successful aging were generally lower for those of advanced age, male gender, and lower socioeconomic status. Between 1998 and 2004, the odds of successful aging declined by 25%, after accounting for demographic changes in the older population.

Discussion.

Few older adults meet the criteria put forth in Rowe and Kahn’s definition of successful aging, suggesting the need for modification if the concept is to be used for broad public health purposes. Disparities in successful aging were evident for socially defined subgroups, highlighting the importance of structural factors in enabling successful aging.
