A depression test tool based on Burns Depression Checklist(BDC).

BDC is a simple but powerful tool for the measurement of degrees of depression.
It's highly recommended to read the book Feeling Good: The New Mood Therapy when using this App.
Combine with this App and the practical skill in the book can bring noticeable improvement on your sense of self-worth.
This App can be used as an Depression tracker.
It help me a lot, and I wish this can help you too.
