Abstract
This study compared the test-retest reliability of the seven motor tests of the Southern California Sensory Integration Tests (SCSIT) with the motor skills subtest of the Luria-Nebraska Neuropsychological Battery—Children's Version (L-NNBC). Both sets of motor performance items were administered twice to a group of 30 dysfunctional 8-year-old children. There was a 1-week interval between test administrations. In addition to reliability comparisons, data were analyzed to determine correlations among individual as well as total motor test scores of the two instruments The test-retest reliability coefficients of the SCSIT motor tests ranged from .41 to .91, while coefficients for the L-NNBC subtests ranged from .30 to .93. Total motor performance scores for the SCSIT and L-NNBC had observed test-retest reliability estimates of .97 and .87, respectively. The total motor performance scores for the two instruments had a correlation of r = .83 for the 30 subjects tested. These findings are discussed in relation to factors that may influence reliability coefficients in normal children as well as children with dysfunctions.
