Short-term retest reliability of the Halstead-Reitan Battery in a normal sample.

Very few studies have examined short-term retest reliability of the Halstead-Reitan Battery in patient samples or normal subjects. The present study examined 3-week retest reliability in a sample of normal healthy subjects. Both psychometric and clinical reliability issues were addressed. On most of the tests the changes between testing were nonsignificant. The measures with the greatest changes were those that appear to incorporate a problem-solving or adaptability component. It was concluded that some of the Halstead-Reitan measures may not be useful in studying short-term changes in performance. On the other hand, most of the measures did not demonstrate significant changes over the 3-week interval and may be useful in examining such short-term changes in performance.
