I was looking up some information on skin picking, when I found this online test to see if you might have compulsive skin picking. It's from The OCD Center of Los Angeles and looks to be very useful.
I didn't bother to take the test, but this is great for anyone that thinks they might have a problem. The realization that I had a problem took many years, and I didn't know anything about dermatillomania when I was growing up. I just thought I had a bad habit and loved to pick my skin and scars.
Please let me know if you think it helped.
