If you're a member of the HiTOP Society, I hope you'll consider voting for me for President 💛 I'd be delighted to lead us in this new chapter Ballots went out today so we can join the current deluge of exciting election results And whether or not you vote for me - please do vote!
A photo of me and statement I wrote about running for President/President-Elect of the new HiTOP Society: 

"I’m so excited to be nominated as President for our new HiTOP Society! I’ve been part of HiTOP for a decade now and have worked hard to advance both the science and the scientific organisation. My research has focused on strengthening the structural validity evidence at HiTOP’s foundations, and I’m committed to improving the model as much as we can.

My leadership in HiTOP started with co-chairing the Revisions Workgroup in 2018, and leading the development of our revisions protocol. This role gave me a seat on the Executive Committee of the Consortium where I’ve worked to strengthen the organisation—for example, proposing and writing our monthly updates for six years, building and maintaining our new website, and using feedback from our members to develop a strategic plan to address the issues many of you raised. That work has also underpinned our shift to a society model, and I would be very proud to have the opportunity to lead us in this new chapter.

I have some ideas of specific things we can work on—setting up awards and small grants for members, for example—but my main focus would be hearing from you all and working to build an organisation that reflects our shared values and ambitions in shaping the future of HiTOP."

I’ve spent the last 8 years(!) working from the position that HiTOP relies too much on analyses of traditional diagnoses, baking in limitations of the DSM, and that we need to move to symptom-level analyses to fix it It turns out that rebuilding HiTOP from the ground up doesn’t change much 💀 1/
A figure of the results from our study, showing a model that looks remarkably similar to the official HiTOP model. There are also important differences like a pathological introversion domain and a combined hypomania/disinhibition dimension.
