I’m excited to get started on my K23 career development award funded by @NIDDKgov. My project will optimize a #DigitalHealth intervention for obesity. I’ll get trained in 1⃣ the #MOST framework + factorial designs, 2⃣ #qualitative methods, & 3⃣ #retention strategies.

Thanks, Sara! A team effort from @GardnerPhD @TheGuyititian @astridnzamora Abby King & Priya Fielding-Singh. Paper coming in 2024.

Excited to have some Stanford v. Duke games to attend out here in California!

Mark your calendars - our Fall 2023 Webinar Series is here! Join us #MOST Wednesdays at 1pm ET to hear from our exciting new lineup. Visit our website to register and for more information about our presenters: https://t.co/zdoDUt8Hap #optimization @nyupublichealth

Loved talking about optimizing behavioral interventions today with @BehavioralMed members. Many great ideas for deciding which intervention components to keep or drop, and effective ways to present results from factorial trials 📊. Thanks for inviting me, @OBBI_SIG!

It was so nice to have an encouraging audience. Thank you all for your smiles and head nods. Next time, I'll have a backup and a backup to the backup 🙃 Sneak peak, below:

So happy to get to collaborate to swap ideas in conducting fully remote trials!

I had a fun conversation with the Harvard Data Science Review podcast team about the benefits of tracking for promoting healthy changes. Thanks for inviting me!

🌟Shout-out to my collaborators: @GoldmanRosas, Abby King, Angel Cleare, & Carly Smith! 🌟Sincere thanks to @StanfordMed & @StanPopHealth for providing funding. I hope this research will shed light on how to make behavioral interventions more impactful, enjoyable, & scalable.

There were several exploratory outcomes. I particularly enjoy waterfall plots to see the variability in weight loss outcomes. Also looked at change in: 👟physical activity (Fitbit steps; GLTEQ) 🍎caloric intake (ASA24) 🫂many psychosocial variables (see Appendix 2)

This study focused on feasibility (retention, engagement) & acceptability outcomes. It was a fully remote trial. The intervention + assessments + study procedures were done remotely using tools like Zoom, Calendly, REDCap, Fitbit, Fitabase, and Box.

How often do people track their food intake if they're asked to track: all foods vs. only less nutritious foods? New pilot study published in @JMIR_Formative (open access): https://t.co/j2RVghVkjf

So grateful to receive funding from the Stanford Diabetes Research Center! I’ll be able to examine the feasibility and acceptability of different types of goals in a digital weight loss intervention.

Duke is getting the cream of the crop for its next Dean. So proud of my PhD advisor, @drgarybennett, for continuing to impress all and forge a unique path. #GoDuke

Plus: The Multiphase Optimization Strategy (#MOST) framework is helpful for thinking about how to gradually build and refine a behavioral intervention over time, with the first phase of MOST focusing on preliminary studies.

Pilot studies “can identify potential weaknesses early in the lifecycle of an intervention & can help avoid failures in larger-scale trials. Failing & discovering on a smaller scale..accelerates the pace for discovering more efficient, effective, & enduring behavior intervention”

🚩A helpful resource for planning your next clinical trial. “What if sufficient power is not possible? Do not initiate miniature versions of larger, proposed full-scale randomized trials...These effect sizes…are more likely to be extreme (high or low) and unstable."

Looking forward to staying at the Stanford Prevention Research Center @StanfordMed, and working with an 🌟all-star🌟 lineup of mentors, including Abby King, @GoldmanRosas, @drgarybennett, @JohnAGallis, & @collins_most!

Should you use an app for weight loss? Listen to @drgarybennett (psychologist, intervention scientist) chat about the digital health space and what ✨key✨ features are needed for impact.
