Abstract
The purpose of the present study was to evaluate the psychometric properties of a shortened version of the Raven Standard Progressive Matrices (SPM) under an item response theory framework (the one- and two-parameter logistic models). The shortened Raven SPM was administered to N = 453 cognitively healthy adults aged between 24 and 83 years. The IQ point estimates that were obtained under the one- and two-parameter logistic models were very similar (r = .97), but the two-parameter logistic-based test version had a higher measurement precision. The results showed that older age and being female were associated with a lower Raven SPM test performance. A user-friendly computer program was provided to facilitate the scoring and norming of the shortened Raven SPM under the different frameworks.Entities:
