Question breakdown, scoring, and interpretation edit

Each question on the questionnaire addresses the existence and frequency of certain anxiety symptoms, the latter of which measured on a 0-5 scale from "absent" to "severe." The section related to OCD symptoms addresses the degree of impairment the symptoms have on the child instead, measured on a 0-5 scale from "no interference" to "severe interference."

The YGTSS as a whole does not have a comprehensive scoring system; however, more symptoms at a higher frequency generally indicate higher severity of a disorder.
