Abstract
Neurobehavioral tests are among the most efficient methods of identifying the adverse health effects of neurotoxicants. The reliability of neurobehavioral tests may be affected by racial or cultural backgrounds, but the widely used computerized neurobehavioral tests have been developed and standardized for Western children. It is thus necessary to assess the reliability of the existing computerized neurobehavioral tests for Korean children. For this reason, 254 healthy 7- to 8-year-old Korean children completed a neurobehavioral test-retest, with the test and retest held two months apart. Six neurobehavioral test items adapted from Korean Computerized Neurobehavioral Tests (KCNT) and modified to match the children's ability levels: Simple Reaction Time, Choice Reaction Time, Color Word Vigilance, Addition, Symbol Digit, and Finger Tapping Speed. The test reliability was assessed using the Pearson product-moment correlation coefficient (r) and the intraclass correlation coefficient (ICC). The ICCs ranged from 0.46 to 0.84 and were very similar to the Pearson coefficients. High reliability was detected in Symbol Digit (r = 0.84, ICC = 0.83), followed by the Finger Tapping Speed of the dominant hand (r = 0.67, ICC = 0.67) and of the non-dominant hand (r = 0.65, ICC = 0.65). The study findings suggest that the reliability of most computerized neurobehavioral tests is appropriate for epidemiological researches on Korean children, and that Symbol Digit and Finger Tapping Speed are more satisfactory bases for the periodic examination of neurobehavioral performance. These findings can also be useful in the future assembly of a neurobehavioral test battery, by providing more stable neurobehavioral test items for Korean children. (C) 2012 Elsevier Inc.
