A shortened version of Raven's standard progressive matrices for children and adolescents
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 45âmin) 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 12âyears and 13 to 16âyears. The short versions predicted the scores on the standard full 60-item versions to a very high degree râ=â0.89 (9-12âyears) and râ=â0.93 (13-16âyears). We, therefore, recommend using the short version to measure general cognitive ability as a background variable in developmental studies
