I've been noticing that “cross-sectional” has become shorthand for “methodologically weak” in (network) research, and often data being cross-sectional is treated as a methodological objection in itself. I took some time to put my thoughts down in writing. Pre-print: osf.io/preprints/ps... 🧵⬇️

New preprint! 🎉 I analysed 1660 papers from 4 psychology journals and found materials sharing went from 9% of papers in 2015 to 82% in 2025, and these materials *do* get downloaded — a median of 135 times each. BUT shared code is often hard to run. doi.org/10.31234/osf... Let's walk through it 🧵
Two-panel figure. Panel a is a flow diagram tracking 1,611 empirical psychology articles from publication year (545 in 2015, 552 in 2020, 514 in 2025) to repository-link type: 785 link an OSF project, 85 link another platform, and 741 link no repository. Of those with an OSF link, download counts were retrieved for 670 and not retrieved for 115. Panel b is a line chart of the share of empirical papers linking OSF across 2015, 2020 and 2025. The overall rate, shown as a dashed black line, rises from 9% to 57% to 82%. All four journals rise steeply and end close together: Psychological Science 92%, JESP 89%, JML 83%, Cognition 76%, with Psychological Science highest throughout.Three-panel figure. Panel a: ridgeline plot of downloads per file by material type on a log scale, with the percentage never downloaded labelled for each — archive 16% of 545 files, documents 20% of 2,970, code 12% of 3,471, other 17% of 1,646, data 21% of 10,051, media 35% of 2,120, images 35% of 4,102. Most files cluster between 1 and 10 downloads, with long right tails past 100. Panel b: ridgeline plot of downloads per paper by journal, log scale, with dashed median lines; Psychological Science is highest, then JESP, JML and Cognition. Panel c: stacked bars showing, for documents, data and code separately, the share of papers by download band (0, 1–10, 11–100, more than 100) in 2015, 2020 and 2025. The share exceeding 100 downloads falls sharply over time in all three types, from roughly two-thirds in 2015 to a quarter or less in 2025, as the 1–10 band grows.Four-panel figure. Panel a: statistical languages detected among 333 papers with retrievable code — R 88%, SPSS 12%, Stata 4%, SAS 1%. Panel b: code red flags among those 333 papers — 34% hard-code an absolute path, 40% reference a missing file — above documentation among 672 OSF-linked papers — 21% have a README, 30% are documented by README, description or wiki. Panel c: among 562 Elsevier papers with no repository link, 44% (245) host at least one journal supplementary file but only 14% (77) host data, code or an archive. Panel d: composition of those 448 hosted files — documents 52%, data 21%, media 9%, other 7%, archive 6%, code 3%, images 1%. The code panels are green, the journal-supplement panels blue.Coefficient plot (download predictors)

Dot-and-whisker plot of three standardised predictors of OSF download volume, each with a 95% confidence interval. Repository size (number of files) has the largest effect at about 0.76, citations about 0.38, and altmetric attention about 0.12. All three intervals sit entirely above zero, so each predicts more downloads, with repository size roughly twice the effect of citations and six times that of attention. X-axis: standardised effect, −0.2 to 1.0.

1/43 Ok folks, after much teasing and anticipation, I'm THRILLED to share our new paper in Annual Review of Clinical Psychology. Not gonna lie: I'm proud of this one, and I hope it makes an impact on the field (so please share!). A thread 🧵👇
To Be a Mental Disorder: Revisiting Behavioral Addictions
Joshua B. Grubbs, * Nicholas C. Borgogna,  Beáta Bőthe,  Hyoun S. Kim,  Rory A. Pfund,  Shane W. Kraus 

Manuscript to appear in the 2027 edition of Annual Review of Clinical Psychology, this preprint may not
exactly represent the final printed copy.

Grubbs, J.B., Borgogna, N.C., Bőthe, Beáta, Kim, H.S., Pfund, R.A., & Kraus, S.W. (2027) To Be a Mental Disorder: Revisiting Behavioral Addictions. Annual Review of Clinical Psychology. 10.1146/annurev-clinpsy-061225-045608

Behavioral addictions have been recognized in various forms for centuries, yet only three—Gambling Disorder, Gaming Disorder, and Compulsive Sexual Behavior Disorder—are currently included in formal diagnostic systems. In the past decade, research on these conditions has expanded dramatically in both volume and methodological rigor, drawing on longitudinal, neurobiological, and cross-cultural designs and evolving into a truly global science. Even so, the field remains beset by unresolved controversies. Chief among these is a persistent tendency to import substance use disorder concepts—tolerance, withdrawal, and dependence—that lack conceptual and empirical support when applied to behavior. Related challenges concern the over-pathologizing of normal engagement and a reliance on confirmatory, self-report measurement of uncertain validity. We argue that advancing the field requires sustained funding, theory grounded in the disorders themselves, objective and intensive-longitudinal methods, greater diversity, and public health and regulatory attention to increasingly technological environments.

Beautiful piece by Awais. Money quote below. My one concern is that many psychiatrists do not in fact mean what Awais means when they say "you have ADHD". They mean it in exactly the same way one says "you have liver cancer". And it's very harmful for mental health science and practice.
