The present study evaluated the reliability and concurrent validity of the new Tanaka B Intelligence Scale, which is an intelligence test that can be administered on groups within a short period of time.
The new Tanaka B Intelligence Scale and Wechsler Intelligence Scale for Children-Third Edition were administered to 81 subjects (mean age ± SD 15.2 ± 0.7 years) residing in a juvenile detention home; reliability was assessed using Cronbach's alpha coefficient, and concurrent validity was assessed using the one-way analysis of variance intraclass correlation coefficient. Moreover, receiver operating characteristic analysis for screening for individuals who have a deficit in intellectual function (an FIQ<70) was performed. In addition, stratum-specific likelihood ratios for detection of intellectual disability were calculated.
The Cronbach's alpha for the new Tanaka B Intelligence Scale IQ (BIQ) was 0.86, and the intraclass correlation coefficient with FIQ was 0.83. Receiver operating characteristic analysis demonstrated an area under the curve of 0.89 (95% CI: 0.85-0.96). In addition, the stratum-specific likelihood ratio for the BIQ≤65 stratum was 13.8 (95% CI: 3.9-48.9), and the stratum-specific likelihood ratio for the BIQ≥76 stratum was 0.1 (95% CI: 0.03-0.4). Thus, intellectual disability could be ruled out or determined.
The present results demonstrated that the new Tanaka B Intelligence Scale score had high reliability and concurrent validity with the Wechsler Intelligence Scale for Children-Third Edition score. Moreover, the post-test probability for the BIQ could be calculated when screening for individuals who have a deficit in intellectual function. The new Tanaka B Intelligence Test is convenient and can be administered within a variety of settings. This enables evaluation of intellectual development even in settings where performing intelligence tests have previously been difficult.
本研究评估了新田中B智力量表的信度和同时效度，该量表是一种能够在短时间内对群体进行施测的智力测验。
对81名居住在少年拘留所的受试者（平均年龄±标准差15.2±0.7岁）施测新田中B智力量表和韦氏儿童智力量表第三版；使用克朗巴哈α系数评估信度，使用单因素方差分析组内相关系数评估同时效度。此外，进行了用于筛查智力功能缺陷个体（智商<70）的受试者工作特征分析。另外，计算了检测智力残疾的分层特异性似然比。
新田中B智力量表智商（BIQ）的克朗巴哈α系数为0.86, 与智商的组内相关系数为0.83。受试者工作特征分析显示曲线下面积为0.89（95%置信区间：0.85 - 0.96）。此外，BIQ≤65分层的分层特异性似然比为13.8（95%置信区间：3.9 - 48.9），BIQ≥76分层的分层特异性似然比为0.1（95%置信区间：0.03 - 0.4）。因此，可以排除或确定智力残疾。
目前的结果表明，新田中B智力量表得分与韦氏儿童智力量表第三版得分具有高信度和同时效度。此外，在筛查智力功能缺陷个体时可以计算BIQ的检验后概率。新田中B智力测验方便且可在多种环境中施测。这使得即使在以前难以进行智力测验的环境中也能够评估智力发育情况。
