Categories	Indicators
Sufficiency The items within the same dimension suffice to measure this dimension	The items are sufficient to measure the dimension
	The items measure some aspects of the dimension, but do not represent the full dimension
	A few items must be added in order to fully assess the dimension

Clarity The item can be understood easily, i.e., syntax and semantics are appropriate	The item is unclear
	The wording of the item requires several modifications or a very large modification in terms of meaning or word order
	Some of the terms in the item require very precise modificationsThe item is clear, with appropriate semantics and syntax

	The item has a tangential relationship to the dimension
	The item has a moderate relationship to the dimension it is measuring
	The item is completely related to the dimension it is measuring
Relevance The item is essential or important, i.e., it must be included	The removal of the item would not affect the measurement of the dimension
