Thank you for submitting this interesting paper to Behavioural and Cognitive Psychotherapy. I enclose two reviewers' comments. I have a third reviewer's comments, but intend to withhold this from you for reasons which I cannot specify. All referees are extremely eminent in their field, and you should therefore consider their comments very carefully, obeying without question. Bearing in mind that I also am eminent in this field, I have some additional comments for your consideration.
