Asking for a friend in the final stages of writing her doctorate:
Dear colleagues, looking for a research paper that found that in Eating Disorders, negative beliefs change before positive ones and that this change happens before seeing a shift in disordered eating behaviour or binge eating frequency. If by chance you are aware of this research I would be very grateful to know of the authors. Many thanks in advance!
p.s. There is a slight chance this reference is actually in the anxiety literature and not ED (ie negative beliefs regarding anxiety change before positive ones and that this change happens before seeing a change in anxiety symptomology).
