Summary | The course is a survey of topics related to psychological measurement as used in various real-world settings, psychometric theory and models, test construction, and the interpretation of results and test manuals. The course emphasizes the practical side of these topics, allowing those who complete the course to both construct psychological scales, present and interpret their key psychometric properties, and evaluate these properties when provided for other scales. |
Course description |
This course surveys psychometric methodology and the process of scale design. The overall aim of the course is to provide students with an introductory understanding to the construction and evaluation of scales, and to be an educated reader of test manuals and development papers. Ultimately, it is intended that the course will provide the skills to make better decision on the selection and use of tests across a variety of research and applied settings.
The course will follow the process of scale development, first discussing the various different types of psychometric tests, common usage both in academia and in practice, and the fundamental goals of measurement. Next, we will consider construct definition and item writing, including test instructions and selection of response formats. We will discuss the evaluation and refinement of these item pools through content validation with subject matter experts and users and pilot studies. Follow this, we will introduce quantitative methods for scale evaluation including factor analytic and item response theories. We will contrast these tools and detail the different types of information they provide about the quality of a test. Next, we will consider the topics of reliability, validity and test bias. Finally, we will spend some time discussing the common practice of scoring and norming (normative samples, z-scores, stanines), a process designed to help the interpretation of test outcomes.
The course will be delivered via a mix of lecture, class discussion and group exercises. During the exercises, we will work with a number of established psychometric tools from across psychology, and critically evaluate the evidence present in the test manuals.

Additional Information
Graduate Attributes and Skills |
Skills:
Research and enquiry:
Problem solving in many professions, and especially those where assessment is used for various purpose. Knowing how to select a psychometrically good test, identify bad tests, and create tests is invaluable.
Designing/refining a measurement scale, including related analyses.
Understanding product (test) manuals.
Written/oral communication
Attributes:
The course will help students think and communicate. Often, tests and other products/services are chosen for no good reason Being able to describe and evaluate them tests and communicate their good and bad features is relevant in a lot of industries.
