Alopecia Areata ≠ Androgenetic Alopecia
I still think it applies though; the psychological effect of being bald probably doesn't care much about the underlying cause.
There's also the fact that Alopecia Areata is actually more common in women, which I imagine exaggerates the distress compared to the more run of the mill MPB.
I realize you didn't mean to use a study on Alopecia Areata, but the difference in degree could be quite large.
