Conceptual and measurement issues in assessing disability cross-nationally: Analysis of a WHO-sponsored survey of the disablement process in Indonesia

The World Health Organization, in collaboration with the Indonesian Institute of Health Research and Development, conducted a survey of disability in 14 of 24 Indonesian provinces. This survey was designed to assess the validity of the disablement process as described in WHO's (1980) classification of impairments, disabilities, and handicaps. We analyzed these data with a multivariate procedure which simultaneously identifies subgroups in the surveyed population and the typical attributes of those subgroups. The purpose of the analysis was to (a) determine the association of basic patterns of physical and psychological impairments with disabilities (limitations of the ability to perform certain functions) and handicaps (limitations in the ability to fulfill social roles); (b) assess how those disabilities and handicaps were expressed in urban and rural contexts in a developing country, and (c) determine how the relation of impairments with disabilities and handicaps varied with age.Drs.
