@sjwithnell.bsky.social
Clinical Psych PhD at Western University, Canada. I study biopsychosocial weight factors related to #eatingdisorders.
It is hardly news that the noisy correlation-based data on ultra-processed foods is very low-quality, but it turns out that the UPF randomized controlled trials probably don't offer strong evidence of the harms of "ultra-processing," either. Gift link: www.vox.com/future-perfe...
The evidence against “ultra-processed” foods is weaker than you think
New analysis suggests other factors may explain the harms blamed on “ultra-processing”

This is an excellent (and entertaining) critique of The Body Keeps the Score, and impressively accurate on the science @ifbookspod.bsky.social podcasts.apple.com/us/podcast/i...

Nice to have some numbers behind my anecdotal feeling (shared by many it seems) that social media platforms have become slop-filled ghost towns
Is social media dying? How much did Twitter change as it became X? Which party now dominates the conversation? Using nationally representative ANES data from 2020 & 2024, I map how the U.S. social media landscape has changed Here are the key take-aways 🧵 Full paper out now in in JQD:DM!
We found that the prevalence of lifetime use was 2.5x higher among people with eating disorders compared to the general adult population. About 1 in 10 people with an eating disorder reported misuse of a GLP-1 drug (e.g., tampering with syringes, accelerating doses, sharing with others). #EDAW
Excited to present at my first European ICED for #ICED2026 in The Hague in June! Share your travel tips for the Netherlands, I've never been and I am stoked about it!!

THANK YOU for this paper! I've been losing my mind wondering why nobody is discussing how the black box of AI models might be a threat to years of open science efforts
New preprint 🌟 Psychology is core to cognitive science, and so it is vital we preserve it from harmful frames. @irisvanrooij.bsky.social & I use our psych and computer science expertise to analyse and craft: Critical Artificial Intelligence Literacy for Psychologists. doi.org/10.31234/osf... 🧵 1/
To be honest I think the global workforce in call-center-like scam factories has already made online surveys without ID verification untenable - if anything LLM's are just putting the people working in these factories out of job
new paper by Sean Westwood: With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research
@sjwithnell.bsky.social from the PEAR Lab at #WesternU is recruiting adults experiencing problems with their eating and/or body image to complete a virtual problem-solving #research study. Compensation will be provided. If you’re interested, check out this poster & complete the screening form!
Would be great to see some more Canadian profs on this list for students looking for clinical psych programs! I think @kvonranson.bsky.social is the only one I spotted 👀
Are you applying to a PhD in Clinical or Counseling Psychology? Here is a list of mentors who are taking students. Please circulate widely so all applicants can benefit 🤓. And if you are a PI recruiting students, please don't forget to add your name! docs.google.com/spreadsheets...
Hi folks, we're still recruiting participants for this study! Please share this post WIDELY with anyone you know who may be eligible to participate! If you'd like to distribute off Bluesky, feel free to DM me and I can get you a blurb and flyer for email or other distribution!
I'm new here! And I'm going to kick it off with recruitment for a research study: If you are a clinician with experience treating eating disorders, please participate in this research study!
📣Please share this opportunity to participate in my PhD research!📣 Adults across the US & Canada experiencing eating/body image problems are invited to participate in a zoom session where you'll complete an interview and a survey. For more info, check out the QR code or contact the lab!
It's becoming clear that, if I want to finish my dissertation, I can no longer avoid learning how to run for/while loops in R. If anyone has any resources on this topic, please let me know! I briefly learned python loops in an undergrad programming class but am extremely rusty!
🚨New paper alert! In my first first-author paper for my #PhD, we explored free-text responses from 1,600+ people with #eatingdisorders to better understand the diverse behaviours used to lose weight, many of which fall outside diagnostic criteria Here's what we found👇
Definitely going to miss hearing a new chapter of the Martian Revolution each week! Loved the touch of imagined books/vids for further reading, but found myself wishing I could read them!
Folks. Check your feeds. It's done
I'm so excited to attend #ICED2025 this week, I might finally install bluesky on my phone! On Thursday I'll be presenting a newly published paper looking at within-person assocs btw weight suppression, weight loss intentions and ED outcomes. Hope to see some folks there! doi.org/10.1016/j.ea...
🚨 New study reveals that when used to summarize scientific research, generative AI is nearly five times less accurate than humans. Many haven't realized, but Gen AI's accuracy problem is worse than initially thought.
You guys don’t need to try to convince me that any form of AI has merit. It doesn’t. It is boring and half-assed. I am fine getting by with human brain power. If the world nears its end and AI has one hater left, good news! I am still alive.
1/x My NIH grant that would collect data to help *prevent suicidal thoughts and behaviors* among LGBTQ+ people was terminated today, along with many other LGBTQ+ focused grants. These terminations make no sense scientifically. Here's why:
I am so excited to share my first publication, a labor of love! My co-1st author @katerinaldi1.bsky.social and I examined weight related terminology preference within two samples of folks in larger bodies🥰 www.sciencedirect.com/science/arti...
Words are heavy: Weight-related terminology preferences are associated with larger-bodied people’s health behaviors and beliefs
Clinicians and researchers may struggle with appropriate terminology when discussing body size. Pathologizing larger bodies has led to use of medicali…

I've been hesitating to share good personal news with everything going on in the world and my own difficulty (re)navigating the impact of serious family illnesses on my studies. But I do have good news and I need to shout about it somewhere! So here we go:
I am still recruiting for my thesis study exploring people's experiences using coaches (e.g., recovery coaches, life coaches, wellness coaches) for eating disorder recovery! Please share!
Coming out of my holiday social media break to share that I'll be presenting at #ICED2025 this year! Hope to catch up with a bunch of academic ED friends in Texas!
Excited to share our infographic and social media toolkit based on our ( @sambedard.bsky.social @cherilev.bsky.social @uofleatlab.bsky.social & Project HEAL) recent paper on barriers to eating disorder treatment access! Check out the social media toolkit here: www.theprojectheal.org/reportedbarr...
