This post seems to be a McNamara fallacy: "if it can't be quantified and measured then its irrelevant and can be ignored".

Look, I don't have any answers here. I'm not involved with teens. I don't really know much about this and maybe the author is correct. But I can spot a bad argument, and fixating only on suicide data and dismissing everything else as "unreliable" (based on a single small study) doesn't seem the right approach.

In addition "mental health" is complex and most people suffering from poor mental health don't commit suicide. There are different types of "mental heath" problems one can have, and it seems entirely plausible that some lead to relatively high rates of suicide and others have much lower rates.
