This workshop aims to introduce participants to measurement theory and the Rasch model for construction and validation of measures. It covers the basic theory behind measurement; from an Item Response Theory perspective; focusing on the assumptions of the Rasch models; in particular. The Rasch model provides the means to create measures (or score scales) from a combination of items in tests or questionnaires. The principles governing the application of such models are shown through examples from educational measurement but are easily applicable to other areas in social and health sciences. Participants will be introduced to various models of the Rasch family (Dichotomous; Rating Scale and Partial Credit) with real research examples and get an opportunity to discuss these and their own examples.
