A lot of commenters have focused on the ADHD, but the 38% number is from anxiety, depression, and ADHD.
... and this generation of students has every reason to be anxious and depressed. I'm surprised the number isn't over 50%. They're watching the white-collar jobs (the kind of jobs that justify a Stanford degree price-tag) get hammered by AI with no plan to back-stop the unemployment resulting than the same answers from the past (i.e. mutterings of "bootstraps" and "saving" and "stop eating avocado toast"), they're watching fascism creep over the nations of the world again, they're watching the annual thermometer rise, the weather get worse, and the world pass tipping-point numbers that our best models suggest will lead to incredibly sweeping climate changes... And they're watching the current leadership of the planet do not enough to address any of this.
I have a teenage niece that is 100% convinced she'll never own a home. I don't have anything concrete to tell her to convince her otherwise.
So yeah... Maybe those double-digit percentage numbers are pretty justified by all of this.
