The organizers of the e-Mental Health Summit (the Trimbos-institute, VU University and University of Amsterdam and the International Society for Research in Internet Interventions [ISRII] board) in collaboration with Gunther Eysenbach, editor-in-chief of JMIR, are pleased to invite summit presenters to submit their paper for a special issue on e-mental health in the Journal of Medical Internet Research (JMIR, www.jmir.org). Guest editors of this special issue will be Heleen Riper, Pim Cuijpers, Helen Christensen and Gerhard Andersson. The deadline for submission is January 8th, 2010 (NEW DEADLINE). NEW: Theme issue submitters are required to indicate their intention to submit a paper to the theme issue by sending an abstract to the coordinating editor, Dr Riper (contact see below) by November 10th, 2009. Publication of the special issue is estimated to be around mid 2010. The usual norms of JMIR are in place, including a fee for Manuscript submission and the JMIR requirements and quality standards. All paper types (original article, viewpoints, reviews) are considered. Submitters are asked to prepare their manuscripts in accordance with JMIR Instructions for Authors (http://bit.ly/8yiaV) and to submit it to JMIR using the online manuscript submission system (http://www.jmir.org/author/submit). IMPORTANT: In step 1 in the submission process, choose the Journal Section "Special Theme Issue (2010) on E-Mental Health (Summit participants only)" from the drop-down list. This is important, as any manuscripts NOT submitted into that "section" will be processed for a *regular* JMIR issue and will NOT be forwarded to the theme issue guest editors! JMIR has now an impact factor of 3.6. If you have any questions you can contact Heleen Riper (firstname.lastname@example.org).
