In general, our findings do not support the existence of a GFP as a single factor of factors at the apex of a personality trait hierarchy that is common across personality inventories. In an EFA context we found that interpretively different GFPs seemed to emerge from different instruments. The discrepancies across measures may be explained by their different content foci (e.g., some measures, such as the HPI, may have been constructed to emphasize adaptation to a work environment more so than others) or development strategies (e.g., the role of factor analysis was greater for some measures, such as the NEO-PI-R, than others, such as the CPI). In general, to the extent that the covariation among personality scales cannot be represented with a single construct, a factor summarizing the covariation of all the scales of any broadband measure should be somewhat arbitrary. It would be questionable in this case to expect a summary score from one measure to relate to a similar summary score on another measure. We suspect the fact that there was any convergence at all likely reflects the
