Assuming this is a relatively standardized protocol this is a great idea. However, getting a score at the end and then the tag line “you’re fine but you should contact us anyway to see if therapy could help” feels icky
If you actually feel fine, then of course therapy isn’t likely to do much for you. The idea is if you’re feeling terrible enough to evaluate yourself, but it turns out you likely aren’t suffering from burnout, that doesn’t mean you shouldn’t look into therapy. Often people think they are suffering from burnout, but it turns out they actually have underlying trauma, anxiety, depression, etc. unrelated to work stress.
Everyone, even healthy people, should attend therapy if able. There's a lot of tricky ground to navigate as a person and you don't have to be experiencing trauma to get help.
Therapy. Therapy is a service, and one that in my experience is of dubious value. It is difficult to look at a statement that is essentially "pay for something you don't need" and not think of it as marketing.
Also questioning how they standardized this. I just got a 20 out of 50 and probably should have gotten a 5 out of 50. If you're not a super-fake optimist then the questionnaire is going to think you are the poster-child for burnout.
