Recent investigations have found significant test-retest decline in certain academic achievement and intelligence test scores in children diagnosed as having acute lymphocytic leukemia (ALL) before 8 years of age. No such effect was observed in children diagnosed at or later than age 8 years. The current study, using a sample of 77 children with ALL, failed to support these findings. No significant differences were found between groups at test or retest nor were significant declines seen for either group from test to retest 1 year later. Reasons for differences in findings between studies, including methodological and samples size differences, are discussed along with implications for future research in this area.
近期调查发现，8岁前被诊断为急性淋巴细胞白血病（ALL）的儿童，在某些学业成绩和智力测试分数上存在显著的重测下降情况。8岁及8岁以后被诊断的儿童未观察到此类影响。本研究以77名ALL儿童为样本，未能支持这些研究结果。在测试或重测时，两组之间未发现显著差异，且一年后两组从测试到重测均未出现显著下降。讨论了研究结果差异的原因，包括方法学和样本量差异，以及该领域未来研究的意义。
