How accurate and reliable is Résuméfit?
Résuméfit uses the WorkPlace BigFive ProFile™ (WB5P) as the primary assessment tool for workplace-relevant behaviors. The test-retest reliability hovers around .90 for all of the traits measured. The coefficient alphas hover around .80 for the five supertraits, and are somewhat lower for the subtraits. Given that this assessment gives maximum information for minimum length, the test has tried to use as few items as possible to measure specific subtraits. In order to raise all subtrait coefficient alphas to the .8 level, the test would have to be substantially longer. If the test were longer, the test would be more accurate, but, then, the test-taker would become more fatigued, which also affects accuracy. So, we have a classic trade-off here. In concurrent validity studies, we find excellent correlation between traits measured on the WB5P and on other Big Five instruments.
