Abstract

Disability is difficulty performing roles and activities due to health problems. It is largely experienced by older persons as they accumulate progressive chronic conditions. To measure functional status of individuals and populations, contemporary surveys include sets of detailed items about disability. Little effort has gone into developing global indicators of disability that cover the concept briefly but well. A global disability indicator is a compact and inexpensive device for public health surveillance and scientific study of disablement. I present and critique items that have been used in North American surveys. Good candidates are selected for methodological study. Both laboratory-based cognitive studies and large-scale statistical studies are recommended; the first will reveal meanings of items and responses and the second, items' systematic structure and prediction ability. The ultimate goal is to identify one or a few fine indicators for widespread inclusion in population health surveys.

      Spain enjoys the longest life expectancy at age 65 of all the members of the European Union (21.5 years) of which 9.1 are spent with disability (European Observatory on Health Systems and Policies, 2019). A common indicator for identifying and monitoring disability is called the Global Activity Limitation Index (GALI) (Robine et al., 2003; Verbrugge, 1997). Similarly to self-rated health, the GALI has been validated and it has proven to be a strong predictor of mortality in different sociodemographic groups (Berger et al., 2015).

      However, the definition of disability is not unique and many frameworks exist to define disability.3 The need for a compact and inexpensive device for public health surveillance and scientific study of disablement4,5 resulted in the past 15 years in the development of a global activity limitation indicator (GALI), which identifies via one question subjects with longstanding limitations due to a health problem. The GALI has been compared with other disability instruments6 and appears to measure functioning and disabilities similarly across European countries.7

    • The global activity limitation index mainly measured functional disability, whereas self-rated health measured physical morbidity

      2014, Journal of Clinical Epidemiology
      Citation Excerpt :

      The success of a comprehensive indicator of health such as self-rated health (SRH) is indicative of the potential usefulness of a global indicator of function [1]. Such an indicator would be useful to describe the functional status of a population, to screen people with disabilities, and for analytical purposes as a prognostic or outcome variable [1,2]. However, it is only recently that efforts have been made to develop such a measure, initially conceived as a global disability indicator and subsequently, under the International Classification of Functioning, Disability and Health conceptual framework, as a global activity limitation indicator [3,4].

      Health status is increasingly recognized as a complex, multidimensional phenomenon (Clark, Stump & Wolinsky, 1997; Johnson & Wolinsky, 1993, 1994; Lawrence, 1995; Leinonen, Heikkinen & Jylha, 1999; Pinquart, 2001; Stump, Clark, Johnson, & Wolinsky, 1997; Wilson & Cleary, 1995; Wolinsky, 1996). In order to deal with some of the complexities, some researchers have examined the changes in individual indicators of self-rated health status (Long & Pavalko, 2004; Wolinsky, Stump, Callahan, & Johnson, 1996), advocated use of a single global disability indicator (Verbrugge, 1997; Verbrugge, Merrill, & Liu, 1999), discussed strategies of measuring morbidity with a simple count of diseases or using binary variables (Ferraro & Wilmoth, 2000), analyzed trajectories of functional limitations (Wolinsky, Armbrecht, & Wyrwich, 2000), or attempted to specify a process of disablement (Jette, 1997, 1999; Jette, Assmann, Rooks, Harris, & Crawford, 1998; Lawrence & Jette, 1996; Leinonen, Heikkinen, & Jylha, 2001; Verbrugge & Jette, 1994). Most of these research efforts have one thing in common: they link health status with chronological aging.

      2010, Journal of Clinical Epidemiology
      Citation Excerpt :

      Measures of disability were introduced into Health Interview Surveys, as self-rated health was felt to be too subjective (despite it correlating well with mortality and health service use [20]), and reported morbidity is sensitive to change over time, level of education, and medical advances. Disability was thought to be more objective, easier to identify by individuals, easier to report (though still subjective as self-reported), and important in determining need not only for health services but also for long-term care [21]. Disability is usually measured through basic personal-care ADL [22] and/or IADL [23], and these often take the form of a minimum of five separate questions although there is a wider range of potential items for any particular survey.
