Class Psychometry II

In this course students recognize the importance of evaluating the psychometric properties of
psychological assessment instruments, not only in terms of instrument construction and validation, but also in their
application in the professional context.

S1. Tests development and construction - Classical Test Theory (CTT)

   S1.1. First phases in test construction: content validity and facial validity

   S1.2. Item construction and its analysis (percentage of concordance between judges., CVI, CVR, Cohen's

   S1.3 Translation and adaptation of instruments: crucial steps and recommendations

S2. Psychometric Qualities of Tests: Definition and Application

    S2.1. Validity

    S2.1.1 Construct validity (factorial (EFA and CFA), convergent, divergent) Criterion validity (concurrent and predictive).

    S2.2 Reliability

    S2.2.1 Internal consistency and temporal stability

S3. Item Response Theory (IRT)

    S3.1. Item Analysis and Scale purification

    S3.2. Model Parameters. fit indices and Graphing

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
