The construct validity of the International Cognitive Ability Resource (ICAR) has yet to be investigated using a gold-standard individually administered intelligence battery. The present study used a convenience sample of 97 students to examine the respective relations between the ICAR16 and overall intelligence (g) and the Cattell–Horn–Carroll broad abilities measured by the WAIS-IV. Large correlations were observed between the observed overall scores (rICAR16, full-scale IQ = .81, p < .001) and the CFA-estimated general factors (r = .94, p < .001). Evidence from confirmatory factor models suggests that the ICAR letter–number Series task measures fluid reasoning, while the matrix reasoning, verbal reasoning, and three-dimensional reasoning tasks measure visual–spatial reasoning (Gv). Findings support the ICAR16 as a valid brief measure of nonverbal intelligence; however, replications in larger samples are needed.

ICAR16 与 WAIS-IV 收敛效度检验

国际认知能力资源 (ICAR) 的结构有效性尚未使用黄金标准单独管理的智力电池进行调查。本研究使用 97 名学生的便利样本来检查 ICAR16 与整体智力 (g) 和由 WAIS-IV 测量的 Cattell-Horn-Carroll 广泛能力之间的各自关系。在观察到的总分（rICAR16，全量表 IQ = .81，p < .001）和 CFA 估计的一般因素（r = .94，p < .001）之间观察到很大的相关性。来自验证性因素模型的证据表明，ICAR 字母数字系列任务测量流体推理，而矩阵推理、语言推理和三维推理任务测量视觉空间推理 (Gv)。调查结果支持 ICAR16 作为非语言智力的有效简短衡量标准；然而，需要在更大的样本中进行复制。
