龚氏非文字智力测验中老年常模的初步编制

Establishment of the Adults and Elderly Norms for Gong's Non-verbal Intelligence Test(GNIT)

目的 :建立龚氏非文字智力测验 (GNIT)中老年人群的初步常模 ,检验它的测量学特征。方法 :在华东、中南和西南地区采样 ,共收集 4 2 7例样本 ,按照 4 5岁以上每 10岁一组 ,75岁以上共一组 ,共分 4组。结果 :常模包括分测验的粗、量表分、总标准分和百分位数。信度和效度均达到了测量学要求 ,量表结构模型比较理想。结论

Objective: The purpose of this study was to develop a set of age norms of GNIT on subjects from 45 to 98 years old and to examine its psychometric characteristics. Methods: 427 subjects (244 males, 183 females) ranging from 45 to 98 years were sampled from East China, Center South China and Southwest China. Four kinds of norms: raw scores, subtest scaled scores, standardized total scores and percentile ranks were obtained. Results: Test-retest reliability coefficients were .85 for standardized total score and .43～.88 for subtest scaled scores. Criterion-related validity studies indicated that the standard score of GNIT correlated .56, .58 and .62 with IQs of WAIS-RC respectively. Conclusion: GNIT has been established as a standardized instrument to measure the intelligence of people over 45 years.
