#LivingReview Update ✨

We’ve submitted our Living Review on #wearables #validation studies (2022–2024) to a special issue of the @jmpbjournal.bsky.social!
Huge thanks to all co-authors — and special thanks to @fiejanis.bsky.social for the lead👏

🔄 Kick-off for the 2025 update already happened today

A Refined #Mobile #Health Intervention (SMARTFAMILY2.0) to Promote #PhysicalActivity and Healthy Eating in a Family Setting: Randomized Controlled Trial Background: Many #Mobile #Health (#mHealth) apps focus on promoting #PhysicalActivity (PA) and healthy eating (HE). However, there is limited empirical evidence regarding their effectiveness in initiating and sustaining behavior change, particularly among children and adolescents. Considering that behavior is influenced by social contexts, it is essential to take core settings like family dynamics into account when designing #mHealth apps. Objective: The purpose of this study was to further develop and refine the SMARTFAMILY (SF) #App targeting PA and HE in a collective family-based setting by enhancing design and usability, as well as by adding gamification aspects, #Health literacy, and just-in-time adaptive interventions to the first version of the #App. Methods: The SF2.0 #App, based on behavior change theories and techniques, was developed, implemented, and evaluated. The #App was used in a collective family setting, with family members using it individually and cooperatively. In a cluster-randomized controlled trial, the intervention group (IG) used the #App for 3 consecutive weeks, while the control group (CG) received no treatment. Primary outcomes included PA measured through self-reports and accelerometry, as well as self-reported fruit and vegetable intake (FVI) for HE. Secondary outcomes included intrinsic motivation, behavior-specific self-efficacy, and the Family #Health Climate. A follow-up assessment (T2) was conducted 4 weeks after the postmeasurement (T1) to assess intervention effects. Multilevel analyses were performed in R (R Foundation for Statistical Computing), considering the hierarchical structure of individuals (level 1) within families (level 2). Results: Overall, 55 families (28 CG, 105/209; 27 IG, 104/209 participants) were recruited for the study. In total, 3 families (3 CG, n=12) chose to drop out of the study due to personal reasons before T0. Overall, no evidence for meaningful and statistically significant increases in PA was observed in favor of the IG of our physically active sample. However, the #App elucidated positive effects in favor of the IG for FVI diary (T0-T1; P=.03), joint PA (T0-T1; P=.02 and T0-T2; P

🧪 Publication alert!
Results of the SMARTFAMILY2.0 #mHealth study show:
- no effect on physical activity in already active families
- increase fruit & veggie intake, joint family activities, and shared meals.

#Conference Time

Last week our members Marco Giugiu, @fiejanis.bsky.social and @irinatimm.bsky.social presented our Wearable Landscape initiative at the International Symposium on Physical Behaviors 🏋️, Wearable Sensing ⌚️, and Health Analytics 🩺.

Thanks to @tu-dortmund.de for hosting this event.

One of the things that has been on my to do list for a very long time, is building a gallery of all of the charts I've made across #TidyTuesday, #30DayChartChallenge, #30DayMapChallenge, and other miscellaneous projects 📊

And it's finally here!

sounds like the review the autism paper would have deserved...

this is one of my favourite observations about sample size calculations. (afaik first articulated by Miettinen in 1985)

🎓I'm thrilled to share that I've successfully defended my doctoral dissertation on July 25, 25. I want to extend my heartfelt gratitude to my esteemed supervisors, Dr. Marco Giurgiu & Prof. Markus Reichert & Prof. Uli Ebner-Priemer, for their invaluable guidance and support 🙏 @mhealthlab.bsky.social

Open science contributes to more rigorous and impactful science. However, little attention is often paid to the benefits that it provides to its users, such as project management and programming skills. Although not its primary objective, these skills may be considered additional benefits supporting the transition to open science practices. Drawing from international perspectives, this chapter will discuss skills that students develop explicitly or implicitly by engaging in open science and their benefits to careers within and outside of academia. It will also showcase examples of how engagement in open science is considered in (academic) hiring decisions, including ongoing debates and areas for (structural) improvement. Ultimately, this chapter will inform educators about the most important open science skills and provide insights into how to strategically build a resume to present open science-related skills convincingly to improve employability, including practical tips and resources.

#OpenScience principles help students gain lots of useful skills that are an advantage on the job market in and beyond academia. Read our latest book chapter where we provide tips for educators to bolster employability through open science: doi.org/10.31219/osf...

I feel you. And getting up is just the follow-up. It never ceases to amaze me how fast the little ones progress. If I'd learn in a year what they learn in a day I'd be happy :D

crtl a, delete, yes

here is the workflow I used. Hope it helps :)

I need help. My day only has 1 meeting, and all emails are done. How does this research thing work again?

Thanks to everybody who chimed in!

I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist.

So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>
