Initial analysis of the Modelling subscale revealed one low-communality item that needed further investigation (item 41 "I model healthy eating for my child by eating healthy myself").
The scenario sometimes ends with a sentence describing the problem to be solved, as shown in Figure 1 (an investigation item), but most of the time the problem is implicit.
Pending further investigation, these items were removed to a storage facility in Munich, where they remained in anonymity until the 2013 Focus article revealed that the cache included works by such Modernist masters as Henri Matisse, Marc Chagall, Emile Nolde, and Max Beckmann, all of whom had been denounced as degenerate artists by the Third Reich.
In a test-retest investigation, most items showed good or very good agreement as a measure of stability.
While these studies demonstrate the use of IRT to examine item difficulty and discrimination the investigation of item differences has also been addressed using classical test theory (CTT).
Our finding that most of the manual item difficulties were disease-dependent emphasises the danger of using generic scales without prior investigation of item invariance across diagnostic groups.
If deemed significant to the investigation, the item was documented, photographed, and kept in the active examination hangar.
The difficulty of most manual activities was diagnosis-dependent, emphasising the danger of using generic scales without prior investigation of item invariance across diagnostic groups.
The finding that the difficulties of most manual activities were disease-dependent emphasises the danger of using generic scales without prior investigation of item invariance across diagnostic groups.
Investigations of items related via category membership only suggest that the variation in hemispheric processing patterns relate to underlying processing conditions, with a LH asymmetry under automatic spreading activation conditions [ 25- 27] and a RH asymmetry under conditions that encourage strategic processing [ 26- 28] or at long SOAs [ 16].
