Construct Validity Project

This assignment allows you to demonstrate an integrative understanding of the contents of the entire course.

You will design a measure of a psychological construct. The construct should be related to your long-term research interests.

You will submit a project proposal and make an appointment with the instructor to go over your proposal. Verbal approval regarding your topic must be obtained from the instructor before you submit your project proposal. See relevant due dates below.

Design a series of studies which would demonstrate the construct validity of your new measure.

Here is a tutorial that may serve as a useful guide for the project.

Academic Integrity

Plagiarizing and cheating on exams and other assignments are not tolerated. Any student exhibiting academic dishonesty will receive an F in the course and will be referred for disciplinary action. Disciplinary action may include expulsion from the university.

Communication

The best way to reach me is by email (wjschne@ilstu.edu) or in person, before or after class. Whenever my office door is open, during office hours or not, it means that I am open to questions, comments, and conversation. I do not check my office telephone messages nearly as often as I check my email. I may, from time to time, email you about various matters.
