6.3.5 Factor analyses

Exploratory factor analysis. Exploratory principal-factor analysis was done, yielding 5 factors with eigenvalues greater than 1 in the Spanish sample (and .9 in the U.S. sample). These factors accounted for roughly 50% of the variance in the Spanish data and 63% of the variance in the U.S. data. Eigenvalues were 9.9, 1.5, 1.2, 1.2, and 1.1 respectively for the Spanish data and 14.3, 1.5, 1.2, 1.0, and .9 in respectively for the U.S. data.

Confirmatory factor analysis. Confirmatory factor analysis also was done. The conceptual framework proposed in Figure 1 provided a 3 x 5 model for the items of the ESJI. We therefore evaluated corresponding three- and five-factor latent variable models for the U.S. and Spanish data.
