I've been very turned off by therapists who have a "thing" whether it be meditation, assigning self help books, "inner child", 12 step programs, or whatever it is that outlines how they treat each patient. Some of these things may be a nice little extra bonus along the way, but if they use it as a full method to treat, I think it is generally a bad sign. So asking questions about their approach is really important. I like to treat it like an informal job interview for them in a way. Also, have a few ideas about what it is you would like to get out of therapy, if you sort of go in there with a general goal they might be able to give you a outline as far as how they would like to approach the problems.
