That being the case, the point remains that a dismissive adult is much more likely to get in the way of a teenager from getting a diagnosis than that of another adult. Furthermore, the fact that doctors are more likely to take men seriously than they do women would explain why the increase in diagnoses is so much higher in male adults than in female adults, even though the base rate of women suffering from mental health issues is actually the same as that of men.

Obviously, the part in italics is fiction. It is referring to the alternate world I mentioned in my comment above where the effect was the the opposite of what we're seeing (with the added extra of adult men appearing to be seeing a greater increase than adult women) and how it's so easy to come up with post-hoc explanations using what seem like reasonable and factual premises.
