【摘要】：目的:為中華成人智力量表(ISCA)建立T分轉(zhuǎn)換系統(tǒng),將測驗(yàn)粗分轉(zhuǎn)換為人口統(tǒng)計(jì)變量校正的T分,并檢驗(yàn)其效度。方法:基于ISCA常模資料為ISCA各分測驗(yàn)分?jǐn)?shù)建立以年齡、性別、受教育程度和職業(yè)等人口統(tǒng)計(jì)變量為自變量的線性回歸模型,將殘差轉(zhuǎn)換為均數(shù)是50、標(biāo)準(zhǔn)差是10、取整的分測驗(yàn)T分。累加6種不同組合的分測驗(yàn)T分,并線性轉(zhuǎn)換為均數(shù)是50、標(biāo)準(zhǔn)差是10、取整的組合T分。計(jì)算95名正常成人(正常組)、102名腦梗死患者(腦梗死組)及與其人口統(tǒng)計(jì)變量匹配的健康配對(duì)者(配對(duì)組)的T分,檢驗(yàn)T分的效度。結(jié)果:生成T分的回歸模型均有統(tǒng)計(jì)學(xué)意義(均P0.001)。正常組的分測驗(yàn)T分平均為46.8~51.3分,沒有殘留人口統(tǒng)計(jì)變量主效應(yīng)。不同受教育程度者之間的分測驗(yàn)T分異常的人數(shù)比例差異無統(tǒng)計(jì)學(xué)意義。腦梗死組分測驗(yàn)T分平均數(shù)為40.7~47.8分,配對(duì)組為48.2~51.7分。腦梗死組有10項(xiàng)分測驗(yàn)T分和6項(xiàng)組合T分均低于配對(duì)組(均P0.01),腦梗死組7項(xiàng)分測驗(yàn)和6項(xiàng)組合T分40分的人數(shù)比例高于配對(duì)組(均P0.01)。結(jié)論:本研究為ISCA建立了T分轉(zhuǎn)換系統(tǒng)。生成的T分與人口統(tǒng)計(jì)變量沒有顯著關(guān)聯(lián),能有效區(qū)分認(rèn)知損害與正常,提示T分轉(zhuǎn)換系統(tǒng)具有一定效度。
[Abstract]:Aim: to establish a T-score conversion system for the Chinese Adult Intelligence scale (ISCA), and to convert the gross score into the T-score corrected by demographic variables, and to test its validity. Methods: based on the ISCA norm data, a linear regression model with age, sex, education level and occupation as independent variables was established for ISCA sub-test scores. The residual error was converted to 50, the standard deviation was 10, and the mean was 50, the standard deviation was 10, the mean was 50, and the standard deviation was 10. Rounded sub-test T score. The T scores of six different combinations were accumulated and converted linearly to a mean of 50, a standard deviation of 10, and a rounded T score. The T scores of 95 normal adults (normal group), 102 patients with cerebral infarction (cerebral infarction group) and healthy matched population variables (matched group) were calculated, and the validity of T score was tested. Results: the regression models with T score were statistically significant (P 0.001). The average T score of the normal group was 46.8 to 51.3, and there was no significant effect of the residual demographic variables. There was no significant difference in the proportion of students with abnormal T scores in different education levels. The mean T score of cerebral infarction group was 40.7 / 47.8, and that of matched group was 48.2 / 51.7. The T scores of 10 subtests and 6 combinations in the cerebral infarction group were lower than those in the matched group (P0.01). The proportion of the seven sub-tests and six combination T scores in the cerebral infarction group was higher than that in the matched group (P0.01). Conclusion: the T-score conversion system was established for ISCA. The generated T score has no significant correlation with demographic variables, and can effectively distinguish cognitive impairment from normal, suggesting that the T score conversion system has a certain validity.
