Yes, it is possible for a T to be too eclectic. I read an article a few years ago -- might have been written by John Norcross, author of "Handbook of Psychotherapy Integration" but I'm not sure anymore -- anyway the article stated that some T's who define themselves as eclectic come across as less skilled and more unsure of themselves because they borrow from too many approaches and never give a single approach enough time to really assess its effectiveness. This can lead to too much inconsistency in treatment, which can cause or exacerbate existing issues with anxiety and trust because the patient never knows what to expect next from the T.
