^^^Indeed, I am in the Psy.D. camp! I love having someone to talk geek with me.
I agree--ASPD and psychopathy are not exactly the same. I was just saying the ASPD criteria spawned from the description of psychopathy. By all means, there is a ton of research that takes other stances so I'm not at all saying you're incorrect. In fact, I think you're onto something by noting ASPD focuses more on behavior rather than personality but lookin. However, looking at the criteria (I'm not well versed on DSM-V because all my comprehensive exams were based on DSM-IV-TR so forgive me on that front), the focus is on behavior with implications about the driving personality traits. For example, lying as
an indication of deceptiveness, physical fights as
an indication of irritability and aggression, etc.
This makes me wonder about patterns in the two girls' behavior. Did they display pervasive patterns of deceptiveness, aggression, manipulation, etc? That probably won't come out until an extensive history and psychological evaluation are done but it will a determining factor in whether psychopathological/ASP traits were at play in their actions. Of course, heavy emphasis will be given to whether they show any remorse or not--I found it interesting that the article didn't mention an apology of any kind.
