Identification of childhood disability in Jamaica: the ten question screen

ABSTRACT

This is the first in a series of papers that report the testing of two instruments for the identification and assessment of childhood disability by community workers (CWs) in Third World countries. It is part of the International Epidemiological Study on Childhood Disability. The Ten Question Screen (TQ) was used as the main instrument to identify disability in a two stage population-based survey of 5478 children aged 2-9 years in Clarendon, Jamaica. In the second stage, TQ positive and 8 percent of the screen negative controls were professionally assessed by a doctor and a psychologist using standard criteria on the main classification system of the ICIDH. Sensitivity of the TQ as a whole varies in different strata of the group and amongst different disabilities, from perfect in girls under 6 years, fits and motor disabilities and for serious disability in all groups except boys over 5 years with a cognitive disability. Specificity was good but the false positive rate was unacceptably high at 74 percent. It was concluded, firstly, that the validation of a simple questionnaire of perceptions of behaviour against objective measurments of impairments was perhaps not fair to the TQ. In spite of this, the TQ would be a very useful instrument in collection disability data for identifying people in need of rehabilitation help, if a way of reducing false positive could be found. (AU)
