An Innovative Approach to Structural Validity, Item Analysis, and Dimension Analysis

Researchers and applied professionals from many different fields, including psychology, sociology, education, political science, and the health sciences, have undoubtedly faced at least one of the following questions:

• How many factors (latent dimensions) are being assessed by my instrument (test, questionnaire, survey, etc.)?
• How stable is the dimensionality solution?
• How good are my items? Do they replicate into the same latent dimensions or not?
• How can I compare multiple dimensionality configurations (or solutions)?
• Is my instrument structurally valid?
• Are my items reliable, or do they merely seem reliable because we are using the common “cheating by repeating” approach?
• How can I answer all these questions if I have (intensive) longitudinal data instead of cross-sectional data?

Too many important questions.

Or maybe you’re just interested in text mining and want to analyze data from social media in order to estimate latent variables.

Maybe you have heard a lot about network psychometrics and want to learn more about it.

Or, being more creative, you just want to know what Russia trolls have to do with dimensionality assessment and reduction and item analysis.

Again, exciting and important questions.

If these are questions you’ve asked yourself, and you’ve been scratching your head staring at the dataset on the screen in front of you, this course is precisely what you’ve been looking for.

Bonus feature: All seminar participants will get exclusive access to the new EGA Wizard AI Assistant (requires a ChatGPT Plus subscription).
