Third, we specified a series of seven CFA models testing the validity of a cross-instrument GFP, as described in detail below. These CFA models were intended to be analogous to those that have been tested in the literature with single instruments. Thus, we only used the scales of measures from the ESCS for which the structure has been tested in previous GFP research, which were the CPI (Rushton & Irwing, 2009a), HPI (Rushton & Irwing, 2008) MPQ (Rushton & Irwing, 2009b), NEO-PI-R (Rushton & Irwing, 2008), and TCI (Rushton & Irwing, 2009a).
