Above are the 10 IRT-based item information curves for the Sexual Compulsivity Scale. The horizontal axes display the values of theta (the value of the latent construct) ranging from −3 to 3. The vertical axes display the range of item information from 0 to 3.5, which indicates how precisely each item measures the construct (SC). Each individual plot shows how much information each item contributes to the scale across the possible values of theta.
