Are you burned out? Are you not sure? Try taking the burnout self test at
mindtools.com. It's a 15 question test taht is supposed to be able to give you an idea on whether you are burned out, close to it or doing OK. this is an informal test and they refer you to something more specifc if you prefer rigorously validated tests.
Note:
This tool uses an informal approach to assessing burnout. While it is intuitively useful, it has not been validated through controlled scientific tests and must therefore not be used as a diagnostic technique. Please, therefore, interpret the results with common sense. Also, make allowances for any recent events that may have a disproportionate influence on your mood at the time you take the test!
If you prefer rigorously validated tests, then the Maslach Burnout Inventory may be useful. This was developed by Christina Maslach, one of the leading researchers in the field of burnout. Copies can be purchased at the following site:
