They are just further descriptive remarks, broken down into single components of the item.
It is examined by creating two subsets of items that are identified by a principal component analysis of the item residuals; those loading negatively forming one set and those loading positively the second set [ 35].
Thus, the question components of the items were the same for all three tests, but the response options for each item differed.
We first explored the underlying component structure of the items by means of exploratory factor analysis (principal component analysis) using principal axis extraction and the varimax rotation method, which maximises the independence of the factors.
Previously, we demonstrated that the physical component of the 36-Item Short Form Health Survey (SF- 36) was influenced (at a p level < 0.0001) by a high disease activity (measured by DAS28) in RA [ 45].
The generic measure was the 12-item Short Form Health Survey (SF-12v2), which is derived from its 'parent measure' the 36-item Short Form Health Survey (SF-36) [ 22, 23], with the 12 items reproducing 90% of the variance in the overall Physical and Mental Health components of the 36 item parent form [ 24].
The Truth, Justice and Reconciliation Commission of Kenya (TJRC) was part of the accountability component of the fourth agenda item in the National Accord [ 6, 7].
The analysis of samples revealed several inaccuracies between the declared compositions for the fireworks and the obtained results, which could be attributed to cross-contamination during their manufacture or to a transfer between other components of the pyrotechnic item.
While the target words of these two sets are the same, other components of the question item (reading passage, correct answer, and distractors) are different, as ones are created by machine while the others are by human.
