Competing Interests

I have read the journal's policy and the authors of this manuscript have the following competing interests: Dr. Saskia Van der Oord, Dr. Pamela Kato and Dr. Kim C. M. Bul have been paid consultants for Janssen Pharmaceuticals, for the development and evaluation of the game Plan-it Commander. This fee was paid to the institution except for Dr. Pamela Kato. Dr. Saskia Van der Oord has been a paid speaker for Shire and Medice (all these activities are related to speaking or researching/developing non-pharmacological interventions for ADHD). Dr. Saskia Van der Oord is a co-developer and author of two manuals concerning cognitive behavioral treatment for ADHD Zelf Plannen (Plan my Life) and Zelf Oplossingen bedenken (Solution-focused treatment); she receives no royalties for sales of any of these interventions. Dr. Athanasios Maras has been a paid consultant to/member of advisory board of/and/or speaker for Janssen Pharmaceuticals, Eli Lilly, Eurocept and Neurim Pharmaceuticals in the past 5 years and is not an employee or a stock shareholder of any of these companies; he has no other financial or material support, including expert testimony, patents, and royalties. This does not alter our adherence to PLOS ONE policies on sharing data and materials. All other authors have indicated they have no competing interests to declare.
