Aim and content
This is a generic course. This means that the course is reserved for PhD students at the Graduate School of Health and Medical Sciences at UCPH. Anyone can apply for the course, but if you are not a PhD student at the Graduate School, you will be placed on the waiting list until enrollment deadline. After the enrolment deadline, available seats will be allocated to the waiting list.

The course is free of charge for PhD students at Danish universities (except Copenhagen Business School). All other participants must pay the course fee.

Learning objectives
A student who has met the objectives of the course will be able to:

1. Know the basic principles for scale validation using IRT models.
2. Validate a simple PRO scale using state-of-the-art methods.
3. Evaluate the quality of a published questionnaire validation.

The course introduces psychometric models for validation of index scales summarizing information from several items. The course covers item response theory models (including Rasch models), detection and modelling of differential item functioning and local dependence. The computer exercises use SAS and specialized software that will be made available.
Ph.D.-students and researchers within medicine, public health, epidemiology, sociology, and psychology. A basic knowledge of statistics will be assumed, as will knowledge of simple methods for scale validation corresponding to the Ph.D. course ‘Introduction to scale validation’. Max. 15 participants.
