In order to use psychometric instruments to assess a multidimensional construct, we may\ndecompose it into dimensions and, in order to assess each dimension, develop a set of items, so one\nmay assess the construct as a whole, by assessing its dimensions. In this scenario, content analysis\nof items aims to verify if the developed items are assessing the dimension they are supposed to\nby requesting the judgement of specialists in the studied construct about the dimension that the\ndeveloped items assess. This paper aims to develop a nonparametric statistical approach based on\nthe Cochran�s Q test to analyse the content of items in order to present a practical method to assess\nthe consistency of the content analysis process; this is achieved by the development of a statistical test\nthat seeks to determine if all the specialists have the same capability to judge the items. A simulation\nstudy is conducted to check the consistency of the test and it is applied to a real validation process.
