Resum: Measures initially designed to be single-trait often yield data that are compatible with
both an essentially unidimensional factor-analysis (FA) solution and a correlatedfactors
solution. For these cases, this article proposes an approach aimed at providing
information for deciding which of the two solutions is the most appropriate and
useful. The procedures we propose are an FA extension of the ‘‘added-value’’ procedures
initially proposed for subscale scores in educational testing. The basic principle
is that the multiple FA solution is defensible when the factor score estimates of the
primary factors are better measures of these factors than score estimates derived
from a unidimensional or second-order solution. Methodologically, new results are
obtained, and relations with factor indeterminacy measures and second-order FA are
discussed. The procedures have been implemented in a noncommercial and widely
known program for exploratory FA. The functioning of the proposal is assessed by
means of a simulation study, and its usefulness is illustrated with a real-data example
in the personality domain.
