a, b PIccc-Diagrams of the Positive Subscale of the PANSS for the forensic sample (1a/left) and the control sample (1b/right). Notes: The upper part of each diagram shows the person-related information (score histogram; green line: Test Information Curve (TIF); red line: Standard Error (S.E.) of the person parameter estimates); lower part: Category Characteristic Curves of the seven PANSS-P-items showing the probability to choose each response category along the latent scale in the interval –4 to 4.
