title: Development and evaluation of CHIPASAT, an attention test for children: II. Test-retest reliability and practice effect for a normal sample.
abstract: The CHIPASAT (Children's Paced Auditory Serial Addition Task), developed to assess auditory-verbal attention, was administered to a sample of 70 normal school children on two occasions separated by an interval of approximately 4 weeks. A significant practice effect was found, independent of age and sex, with performance improved by approximately 20% on retest. The test-retest reliability of .90 was significant, indicating task stability. The practice effect was consistent with that reported in the literature for the adult PASAT, and reasons for this effect are discussed. Initial test raw scores on WISC--R Arithmetic and Digit Span subtests yielded low but significant correlations of .38 and .35 with CHIPASAT scores.
