Reliability of tests and measures used in the neuropsychological assessment of children

Abstract
Reliabilities of the tests that comprise Reitan's neuropsychological batteries for children, as well as other allied tests of neuropsychological functioning used in the assessment of children, were examined. A heterogeneous sample of 248 youngsters who had been evaluated more than once over an average of 2.6 years was drawn from a population of 3600 children referred for neuropsychological assessment. Pearson and intraclass correlation coefficients were calculated on the data provided by these children. The results demonstrated a high degree of reliability for many of the 50 variables studied. A hierarchy of reliability coefficients is presented as is a discussion of the pattern of consistency and stability in evidence.
