De constructie van een CQ-index meetinstrument: ervaringen uit de praktijk.

The development of a CQ-index questionnaire consists of several phases. In this article the construction of a questionnaire and the statistical analyses with regard to the psychometrical properties and discriminative capacity of the instrument are discussed. The description will be illustrated with examples from four CQI’s: the CQI General Practice, the CQI Hip/knee-surgery, the CQI Mammacare and the CQI Reumatoid Artritis. The experiences with different phases of the construction process as well as with the CQI systematics in general will be discussed.(aut. ref.)
