Dispositional greed scales

In recent years, different scales have been developed to assess individual differences in dispositional greed. We report two studies (N1 = 300, N2 = 1,000) on the comparative psychometric properties of these scales. We find that all scales are reliable and that they correlate highly, suggesting that all can be used to assess dispositional greed. Exploratory factor analyses, using the Empirical Kaiser Criterion, the Hull method, and Parallel Analysis as extraction methods, were done on the separate scales and all items together. These analyses reveal that there is quite some consistency in the scales, as in both studies a one-factor solution seems to describe the data best. These results imply that these different scales all assess dispositional greed, although the results also suggest that some items may be deleted from the scales
