Is the CDGAD suitable for all ages?

Are there translations of the CDGAD?
At present, only a Spanish version is available. This has been fully validated and described by Bobes et al (2006). There are minor adaptations for Spain and for America.
How long does it take to complete the CDGAD?
The average time is 4 – 6 minutes.
What are main uses of the CDGAD?
There are three main uses. It can be used to detect the likelihood of GAD, i.e. as a diagnostic screener. 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?
Because the CDGAD is protected by copyright, it is not permissible to include it in any reports or publications.
How do I deal with missing responses?
It is recommended that the entire scale must be completed in order to interpret the results. A partially completed CDGAD is invalid.
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.
