There were actually a few participants who said they found the trout activity relaxing and had thought about it over the four-week study period. So it may have been a stronger control than we had hoped!

🚨 New Preprint 🚨

Some people are at greater risk of experiencing negative mental health outcomes of social media use than others, but why?

Development of an Offline-Friend Addiction Questionnaire (O-FAQ): Are most people really social addicts? - Behavior Research Methods A growing number of self-report measures aim to define interactions with social media in a pathological behavior framework, often using terminology focused on identifying those who are ‘addicted’ to engaging with others online. Specifically, measures of ‘social media addiction’ focus on motivations for online social information seeking, which could relate to motivations for offline social information seeking. However, it could be the case that these same measures could reveal a pattern of friend addiction in general. This study develops the Offline-Friend Addiction Questionnaire (O-FAQ) by re-wording items from highly cited pathological social media use scales to reflect “spending time with friends”. Our methodology for validation follows the current literature precedent in the development of social media ‘addiction’ scales. The O-FAQ had a three-factor solution in an exploratory sample of N = 807 and these factors were stable in a 4-week retest (r = .72 to .86) and was validated against personality traits, and risk-taking behavior, in conceptually plausible directions. Using the same polythetic classification techniques as pathological social media use studies, we were able to classify 69% of our sample as addicted to spending time with their friends. The discussion of our satirical research is a critical reflection on the role of measurement and human sociality in social media research. We question the extent to which connecting with others can be considered an ‘addiction’ and discuss issues concerning the validation of new ‘addiction’ measures without relevant medical constructs. Readers should approach our measure with a level of skepticism that should be afforded to current social media addiction measures.

Had missed this absolutely brilliant paper. They take a widely used social media addiction scale & replace 'social media' with 'friends'. The resulting scale has great psychometric properties & 69% of people have friend addictions.

The threat of analytic flexibility in using large language models to simulate human data: A call to attention Social scientists are now using large language models to create "silicon samples" - synthetic datasets intended to stand in for human respondents, aimed at revolutionising human subjects research.

Can large language models stand in for human participants?
Many social scientists seem to think so, and are already using "silicon samples" in research.

One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.

This was the largest trial of SSIs, and the first ever megastudy of mental health interventions. Thanks to leadership from @protzko.bsky.social, @lluaces.bsky.social, @matnoc.bsky.social, @stephenschueller.bsky.social, and @jschleiderphd.bsky.social, and all 50 teams who submitted SSIs!

The most successful SSIs’ content and styles varied a lot, but broadly, they provided focused, engaging, and actionable guidance on a skill that was important to users.

We think future work should aim to leverage SSIs’ short-term gains toward more sustained behavior change or service engagement.

We randomized 7,505 American adults experiencing depression to one of the 12 SSIs or a control.

Nearly all SSIs boosted agency and hope for improvement immediately (Cohen's ds ≤ 0.37). However, only two significantly reduced depression four weeks later (ds = 0.14 and 0.15).

Digital single-session interventions (SSIs) have been shown to improve depression, with small effects and in limited settings. We wanted explore ways to make them better.

To learn which kinds of SSIs work and which don’t, we crowdsourced 66 diverse SSIs from global teams and chose 12 for testing.

New paper out today!

We present two RCTs challenging the idea that longer digital single-session interventions for mental health must be more efficacious.

This matters because briefer interventions (e.g., 8 mins vs. 23 mins) are likely to reach more people.
