HeadtoHead is a collaborative blog linked to the BMJ journal Evidence Based Mental Health. With this blog we aim to foster an exchange of ideas as well as influence what the journal offers its readers. You are welcome to join in and comment on any of the journal’s contents, or draw our attention to what else is going on in the world of mental health. Postings will be screened but we are keen to encourage robust debate at EBMH. So as long as you’re not libellous or abusive and your comment or response is relevant you will be heard. Feel free to be prolix, ask a seemingly daft question, or simply point out when something just doesn’t make sense. The conversation starts here.
