Evaluation research in long-term care. Scope and methodology

In their own words: a model of healthy aging

Many previous studies have assessed the aging process by measuring clinical and functional variables. To supplement that quantitative understanding, we asked older people what constitutes their health and contributes to it. Using grounded theory-type methods, we analyzed semi-structured interviews with 22 study subjects, who were randomly selected from among those whose reported perceived health differed from that predicted by a regression model constructed from data from a randomized trial of a primary care intervention. We focused on disparate cases to identify factors that best discriminate between more and less healthy aging. Interview questions targeted perceptions of health; well-being; valued abilities, activities, and relationships; social support; control; sense of coherence; and personal outlook. A model of healthy aging emerged. To these older people health meant going and doing something meaningful, which required four components: something worthwhile to do, balance between abilities and challenges, appropriate external resources, and personal attitudinal characteristics (e.g., positive attitude vs. "poor me"). By reframing healthy aging in older people's own terms, this model encourages interdisciplinary support of their desired goals and outcomes rather than only medical approaches to deficits and challenges.

Assessing the impacts of community-based health care policies and programs for older adults

This article presents a framework for evaluating long-term care policies and programs to determine how well community-based programs benefit the older adult population. Equity, accessibility, quality, and efficiency are identified as core criteria for implementing and evaluating long-term care policy. Special problems with conducting process and/or outcome evaluation of community-based programs are noted, and findings of evaluation research on community-based health care programs are reviewed. Most previous research indicates that community-based health programs for older adults are not a substitute for institutional care and do not reduce either informal caregiving or ambulatory medical services. The article concludes with policy implications.
