DAPR3 Block 2

Start

I have lots of variables measuring the same construct X.

I want scores for X

(e.g., to use in a subsequent analysis)

I want to understand what it is I am measuring, and how.

(e.g., is there just one dimension to X, or are there multiple sub-domains?)

I want to evaluate the psychometric quality and structural validity of X

(e.g., testing a theoretical measurement model, or assessing reliability)
