You're back! As usual, poking us gently, challenging our settled notions. An entertaining read, and of course, well researched. I will note two statements that jump out at me:

(substance abuse is given as an example of what the authors mean by "acting out"), whereas girls do it by complaining about their health.

There will have to be a lot of cold days in July before I accept those results. Just too close to the stereotypical model of the 'hysterical' female.

a significant percentage of adolescents (80%) do not experience adolescent turmoil, relate well to their families and peers, and are comfortable with their social and cultural values

I don't know about that one, @alexander.alexis :) Most teachers avoid middle school if they can help it (ages 11-14). Generally it's believed that group of kids undergoes a temporary lapse of sanity.

I'm just finishing a post with a little something written with you in mind...a reference our mutual "friend" Freud. I hope you are amused :)

EDIT
I forgot to add, this is brilliant:

But with the stereotype of the adolescent as presented above, parents chuck teens' moodiness up to Sturm und Drang, often ignoring warning signs, which is why it's important to dispel the stereotype.

Parents should never chuckle when the kids are distressed...really. I worked with suicidal and depressed kids as a teacher. Kids don't talk. We have to look for signs. You don't want to be the parent who overlooked one of those signs. Some mistakes you can't take back.
