There has been increased interest in assessing the quality and usefulness of short versions
of the Raven’s Progressive Matrices. A recent proposal, composed of the last twelve matrices of the
Standard Progressive Matrices (SPM-LS), has been depicted as a valid measure of g. Nonetheless, the
results provided in the initial validation questioned the assumption of essential unidimensionality
for SPM-LS scores. We tested this hypothesis through two di erent statistical techniques. Firstly, we
applied exploratory graph analysis to assess SPM-LS dimensionality. Secondly, exploratory bi-factor
modelling was employed to understand the extent that potential specific factors represent significant
sources of variance after a general factor has been considered. Results evidenced that if modelled
appropriately, SPM-LS scores are essentially unidimensional, and that constitute a reliable measure of
g. However, an additional specific factor was systematically identified for the last six items of the test.
The implications of such findings for future work on the SPM-LS are discussed
