Introduction to Item Response Theory

Image of a measurement model describes how unobservable concepts (latent variables) are linked to observable data.

Ama has been invited multiple times to deliver an introductory lecture on Item Response Theory (IRT) for the Social Welfare Advanced Research Methods course at the University of Pennsylvania. In her presentation, she explores the significance of measurement theories, the development of IRT as a model-based approach to measurement, key distinctions between Classical Test Theory and IRT, and practical applications of IRT in social work research and practice.
