Numerous developmental studies assess general cognitive ability, not as the primary variable of interest, but rather as a background variable. Raven’s Progressive Matrices is an easy to administer non-verbal test that is widely used to measure general cognitive ability. However, the relatively long administration time (up to 45 min) is still a drawback for developmental studies as it often leaves little time to assess the primary variable of interest. Therefore, we used a machine learning approach – regularized regression in combination with cross-validation – to develop a short 15-item version. We did so for two age groups, namely 9 to 12 years and 13 to 16 years. The short versions predicted the scores on the standard full 60-item versions to a very high degree r = 0.89 (9–12 years) and r = 0.93 (13–16 years). We, therefore, recommend using the short version to measure general cognitive ability as a background variable in developmental studies.

Raven 的儿童和青少年标准渐进矩阵的缩短版本

许多发展研究评估一般认知能力，而不是作为感兴趣的主要变量，而是作为背景变量。Raven 的渐进矩阵是一种易于管理的非语言测试，广泛用于测量一般认知能力。然而，相对较长的给药时间（长达 45 分钟）仍然是发育研究的一个缺点，因为它通常很少有时间来评估感兴趣的主要变量。因此，我们使用机器学习方法——正则化回归与交叉验证相结合——来开发一个包含 15 项的简短版本。我们对两个年龄组进行了研究，即 9 至 12 岁和 13 至 16 岁。简短版本对标准完整 60 项目版本的分数预测到非常高的程度r  = 0.89（9-12 岁）和r = 0.93（13-16 岁）。因此，我们建议使用简短版本来衡量一般认知能力，作为发展研究中的背景变量。
