Silly test. Half the questions is something anyone in their right mind would have to answer yes to under certain conditions.
With so few questions, even a single/few yes'es will result in a "moderate" level of disorder.
A "real" questionnaire for profiling consists of 500-1000 questions, sometimes more, and is coupled with observation of behaviour. Even then the result is questionable (as we see in the over-representation of ADD medicine prescriptions, for instance).
