The graphing will allow you to monitor the progress of recovery from anxiety and or depression, how events may be affecting your mood or if you are controlling your stress levels well.

The DASS and Diagnosis

The DASS is not meant to replace a comprehensive interview with an appropriately qualified professional so if your score is high and/or if you have any concerns please see your local doctor or clinical psychologist.
