“…Rather, the key question in research on higher order constructs has been, What does it buy us in terms of building new knowledge to study individual variables that may reasonably be considered as measures of the same higher order construct? The answer has been that measures that appear similar should be evaluated, and when there is a conceptual or empirical reason to suggest the existence of a higher order construct, such a commonality should be given attention (Block, 1995;Cronbach, 1956;Dawis, 1992;Judge, Locke, & Durham, 1997; E. L. Kelley, 1927;Watson & Clark). I believe that the conceptual evidence points out that hope, self-efficacy, optimism, and resiliency may share a common confidence core.…”
