update 12 Jan 2012 12.15 hrs: We still don't have our second winner! OK - simply RT the Digest's Twitter message about this competition today and I'll pick a winner at random at the end of the day. Good luck.
update 9 Jan 2012, 10.22 hrs: The rules of the competition have been relaxed. There's still one copy left to win. Now you need only have someone with more than 50,000 followers retweet you mentioning @researchdigest and #psychopathologycomp. The winner themselves must have fewer than 50,000 followers. Let me know (via @researchdigest) if you succeed. The first person to succeed, and inform me they've done so, will win the book. Good luck!
update 19 Dec, 13.50hrs: one copy still left to be won.
