Do household surveys give a coherent view of disability benefit targeting?: a multisurvey latent variable analysis for the older population in Great Britain.

We compare three major UK surveys, the British Household Panel Survey, Family Resources Survey and the English Longitudinal Study of Ageing, in terms of the picture that they give of the relationship between disability and receipt of the attendance allowance benefit. Using the different disability indicators that are available in each survey, we use a structural equation approach involving a latent concept of disability in which probabilities of receiving attendance allowance depend on disability. Despite major differences in design, once sample composition has been standardized through statistical matching, the surveys deliver similar results for the model of disability and receipt of attendance allowance. Provided that surveys offer a sufficiently wide range of disability indicators, the detail of disability measurement appears relatively unimportant.
