Covariance-Based Structural Equation Modeling (CB-SEM): Module 2 on Reliability and Validity

Dear All:


Welcome to the second module of the lecture series on CB-SEM. In this module, I introduce the ideas of reliability and validity. The module has 5 lectures: first three cover reliability and the last two cover validity.

Lectures 1 and 2 cover the basics of reliability, the mathematics behind Cronbach’s alpha, how to compute Cronbach’s alpha using hand and the importance of reliability in Psychometrics.

Lecture 3 demonstrates how to compute reliability (Cronbach’s alpha) using SPSS.

Lecture 4 discusses the idea of validity and describes the different kinds of validity discussed in research, namely, content validity, face validity, discriminant validity, convergent validity, criterion validity and construct validity.

Lecture 5 describes nomological validity.

These lectures will be useful as we discuss the other ideas relating to SEM in the coming modules.
