  • Objectives


    It is intended that students should be able to:

    LO1. develop their knowledge of the main methods for test development, 

    LO2. reflect critically on the pros and cons of each method,

    LO3.  develop practical skills to assess the psychometric properties of psychological tests.

    LO4. know the assumptions of psychometric methods in the application areas of psychological science.

  • Teaching methodologies and assessment

    Teaching methodologies and assessment

    Classes are theoretical-practical and based on the use of expositive and interrogative teaching methods, for presenting the topics and fostering students’ participation, respectively. In order to consolidate the knowledge, topic presentation is based on several examples of studies in the field of clinical and health Psychology. To highlight the application of the topics, the active method is preferred, focused on problem-solving using a collaborative and blended learning approach. The UC contents are fully available  in various formats, such as .pdf, videos or URLs on Moodle
