I came across these after finding the Pain Scales and find the Zung Self-Assessment Tests for Anxiety and Depression intriguing. It was nice to run through them myself rather than have the added stress of an MD do it.
As expected, and fyi my scores were:
Anxiety 75/80
Depression 76/80.

Then, for fun, I took the Personality Type Indicator (MBTI) Test.
This tells me I am an ISTJ Type - The Examiner. Reading through the meaning on Wikipedia, I find it accurately describes me as logical, introverted, steadfast, loyal, etc, etc.
Funny thing is, if you look at my Chinese Zodiac character, The Ox, you will find I'm logical, introverted, steadfast, loyal, etc, etc…
Read into this what you will.
