Evaluating untimed and timed abridged versions of Raven’s Advanced Progressive Matrices

Abstract

Introduction: Raven’s Advanced Progressive Matrices (APM) are frequently utilized in clinical and experimental settings to index intellectual capacity. As the APM is a relatively long assessment, abridged versions of the test have been proposed. The psychometric properties of an untimed 12-item APM have received some consideration in the literature, but validity explorations have been limited. Moreover, both reliability and validity of a timed 12-item APM have not previously been examined. Method: We considered the psychometric properties of untimed (Study 1; N = 608; Mage  = 27.89, SD = 11.68) and timed (Study 2; N = 479; Mage  = 20.93, SD = 3.12) versions of a brief online 12-item form of ..
