I would assume it depends on whether it's privately ran, ran by govt or combo. Combo would most likely be most effective. Govt would be ok if it was supervised by someone competent and private would be ok if good money was involved. For this one though, I am not sure who runs it or if any supervision is in place to keep it 100% accurate. As I do, I would suggest to take it for what it's worth, but always assume their are more out there, not on this list, for whatever reason.
Anger itself does more harm than the condition which aroused anger.
