Dear Dr. Qwerty: When a target article or recent book has been accepted for BBS Commentary, the editorial office sends out the Call for Commentary Proposals to thousands of people. Commentary Proposals help the BBS Editors craft a well-balanced commentary invitation list. If this target article interests you as a possible subject for commentary, please download the full pre-print to see if you would like to propose a commentary. If you are interested please follow the instructions below the target article information. Please keep in mind that we are not asking you to submit a commentary -- but rather, a short proposal in order to be considered as an invited author after the proposal deadline. Please also be aware that we typically get far more proposals than we can accept. NOW ACCEPTING COMMENTARY PROPOSALS ON: Target Article: "Comorbidity: A network perspective" Author: Angelique Cramer, Lourens J. Waldorp, Han L. J. van der Maas, Denny Borsboom Deadline for proposals: December 30, 2009 Abstract: The pivotal problem of comorbidity research lies in the psychometric foundation it rests on, i.e., latent variable theory, in which a mental disorder is viewed as a latent variable that causes a constellation of symptoms. From this perspective, comorbidity is a (bi)directional relationship between multiple latent variables. We argue that such a latent variable perspective encounters serious problems in the study of comorbidity, and offer a radically different conceptualization in terms of a network approach, where comorbidity is hypothesized to arise from direct relations between symptoms of multiple disorders. We propose a method to visualize comorbidity networks and, based on an empirical network for major depression and generalized anxiety, argue that this approach generates realistic hypotheses about pathways to comorbidity, overlapping symptoms, and diagnostic boundaries, that are not naturally accommodated by latent variable models: some pathways to comorbidity through the symptom space are more likely than others, those pathways generally have the same direction (i.e., from symptoms of one disorder to symptoms of the other), overlapping symptoms play an important role in comorbidity, and boundaries between diagnostic categories are necessarily fuzzy.

In the Description field please add the first author name of the target article or book. For example; "Commentary Proposal on Cramer et al." 7. Approve Your Submission Editorial Manager will process your Commentary Proposal submission and will create a PDF for your approval. On the 'Submissions Waiting for Author's Approval' page, you can view your PDF, edit, approve, or remove the submission. Once you have Approved the Submission, the PDF will be sent to the editorial office. **It is VERY important that you check the and approve your Commentary Proposal manuscript as described above. Otherwise, we cannot process your submission.** Note: If you have designated a different Corresponding Author, only the new Corresponding Author will have access to the PDF and must log-in to the system in order to approve the PDF. 8. Editorial Office Decision At the conclusion of the Commentary Proposal period, the editors will review all the submitted Commentary Proposals. An undetermined number of Commentary Proposals will be approved and those author names will be added to the final commentary invitation list. At that time you will be notified of the decision. If you are formally invited to submit a commentary, you will be asked to confirm your intention to submit by the commentary deadline. Note: Before the commentary invitations are sent, the copy-edited and revised target article will be posted for invitees. In the case of Multiple Book Review, invitees will be sent a copy of the book to be commented upon if requested. With Multiple Book Reviews, it is the book, not the Précis article that is the target of commentary. Please do not write a commentary unless you have received an official invitation! SPECIAL NOTE Since this is our first year on Editorial Manager, we would like your feedback regarding how the process could be improved. Please let me know if you have any questions or concerns. BEING REMOVED FROM THE CALL EMAIL LIST If you DO NOT wish to receive Call for Commentary Proposals in the future, please reply to bbsjournal(a)cambridge.org, and type "remove" in the subject line.
