I would try contacting the state to confirm, but I would personally read that in light of 430 ILCS 65/4(a)(2)(iv) - that an applicant is to submit evidence that "He or she has not been a patient in a mental institution within the past 5 years and he or she has not been adjudicated as a mental defective". That is, I interpret the statute as contemplating inpatient treatment. Unfortunately I don't see an authoritative source addressing the language.
