Results: The GIS shows excellent discriminant validity, distinguishing patients with PANS from healthy controls. The scores on the GIS show an acceptable level of agreement with the clinician-reported CGAS. The regression line in the Bland–Altman plot had a positive slope, indicating that parents tend to report higher disease severity than clinicians at higher levels of disease severity. Correlation was higher during disease remissions than during disease flares (r = −0.69 vs. r = −0.48). All disease severity scales predicted GIS in the expected direction
