It can also be used as a measure of the severity of GAD, on a scale where 0 represents no symptoms and 12 suggests very severe GAD. Thirdly, it can measure response to treatment when given repeatedly over time. If the scale is being used as a diagnostic screen then it is important to follow up with a clinical interview to substantiate the finding.

Is it possible to include the scale in reports, dissertations or publications?

What is the minimum educational level required to understand and complete the scale?

A high Flesch Reading Ease score of 87.0 was obtained, and the Flesch-Kincaid Grade Level was 2.7. So with at least a third grade level education, the scale can be easily understood.
