The simplest, most direct book by Edna Foa and Reid Wilson puts total emphasis on a self-help program that takes enormous motivation to comply with. Methods suggested include cognitive-behavioral self-talk regarding irrationality of obsessions, altering images that provoke distress, tackling feared consequences of not ritualizing by accepting that obsessions are irrational, and allow oneself worry time twice a day and accept that it is ok to worry during that time. This book also suggests creating a loop tape of a "worry story" that is one's worst fear coming true, and playing it over and over until it becomes hard to pay attention and take it seriously. It offers a nice balance of differing methods useful for checkers, washers, counters, repeaterers, orderers.
