Alternatives: "definitive item" or "complete item".
True positives were predicted by CAT item usage, absolute item difficulty and item discrimination.
Items were considered to be part of a PC if absolute item loadings were ≥0.45.
True positive rates were primarily predicted by CAT item usage, absolute item difficulty and item discrimination.
There are two likely explanations for the observed relationship between absolute item difficulty and power in DIF detection.
CAT item usage was found to be the single best predictor of detecting simulated mode effects, followed by absolute item difficulty.
This would likely explain why absolute item difficulty was a significant predictor of power even after controlling for CAT item usage.
My absolute favorite item, however: the Goldman Sack.
Preliminary analyses revealed that absolute values of item difficulty better predicted correct DIF detection, whereas signed item difficulty values more accurately predicted incorrect DIF decisions.
As Cronbach's α depends on the absolute number of items included, 42 two criteria were used: for more than 10 items α > 0.70 was considered acceptable; for less than 10 items α>0.50 was considered acceptable.
Thus, at least with this approach, we can't reach any conclusions about the absolute amount of item-specific information at 200ms versus 400ms.
As shown in Table 4, for the perceived probability of genetic predisposition to cancer assessed at T1 on the 0 100% one-item absolute scale, means were significantly different across the clinician-computed estimate categories (respectively: F 3,192)=8.0, P<0.001, η=0.11).
