| Annotation | The models and measurement strategies used in studies evaluating the predictors of nursing home placement, hospital admission, functional impairment and mortality are reviewed. To do so, the authors examined 167 multivariate equations abstracted from 78 longitudinal studies published between 1985 and 1998 that assess the risk factors of one or more adverse outcomes. It was found that both comparatively straightforward concepts such as age and income, and widely used scales such as activities of daily living (ADLs) and the short-portable mental status questionnaire display considerable variability in operation and coding. Few researchers employ explicit conceptual models to assist with variable choice, while some predictors (demographics, and physical and cognitive functioning) were studied much more frequently than others (service, market and policy characteristics). Variability in measurement highlights the lack of standardisation in this area of ageing research, and leaves room for improvement in validity and reliability. Limited use of conceptual models has led researchers to include some predictors in their analyses to the exclusion of others. (KJ/RH). |
