This is awesome! We're working on a (very short) methods introduction paper on this approach. Instant cite for your preprint.

increase...reduction...surge (?!) from cross sectional data. What are they even measuring? SFV & attention definitely deserves research focus, but I'm not convinced that the existing body of work provides any informative signal. Correlations based on self-reports of, in most cases, other things.

Looks super interesting! I see from this talk www.youtube.com/watch?v=DSgR... that @davidlazer.bsky.social gave that they have app-level data and biweekly mental health data too. cross-device data (well browser/phone) is also nice for studying behaviour

I know the OP is tongue-in-cheek but out of interest I ran a quick-and-dirty check on SCOPUS. Looks like 1 review for every 10 primary papers (though probably an undercount for primary papers). I don't know what the ratio is for other areas, but that feels high?



Query A: Primary studies

TITLE-ABS-KEY(
  ("screen time" OR "digital media use" OR "social media use"
   OR "smartphone use" OR "internet use")
)
AND (DOCTYPE(ar))
AND NOT (
  DOCTYPE(re)
  OR TITLE("review" OR "meta-analysis" OR "systematic review" OR "umbrella review")
)

= 28906 results

Query B: Reviews

TITLE-ABS-KEY(
  ("screen time" OR "digital media use" OR "social media use"
   OR "smartphone use" OR "internet use")
)
AND (
  DOCTYPE(re)
  OR TITLE("review" OR "meta-analysis" OR "systematic review" OR "umbrella review")
)

=2846 results

Review density (reviews/100 studies) = 9.85 reviews per 100 primary studies

Hard to know given the wide range of what "ban" actually meant here...

For #ICA26 I received many very useful reviews (on both accepted and rejected papers) but I think these two take the cake (on a student led paper). Sure, it’s what we wanted to hear, but…

YouTube now offering 4x playback speed... um, what? I quite regularly speed up content but 4x feels excessive. I'm genuinely curious what the experience is (not a premium subscriber) and motivations would be here (both for users and the platform).

We're talking correlations here though... "In each model, we used the social media use variable measured at the same time point as the outcome variable (i.e., from the same evening)."

Out of interest, this was what the data look like for each track listened to. With the Spotify API more info on the track can be pulled to augment the listening history data.

We outline a set of plausible direct and indirect mechanisms that now enter the conceptual frame to move the field beyond the capacity focus and consider intra-individual variation and situational regulation when studying digital technology use and attentional control Feedback welcome!

Rather than (only) occurring at the level of capacity (as current research implicitly argues but largely fails to show), considering intra-individual variation opens up the possibility that effects occur at the level of situational regulation (control-learning and/or motivated control mechanisms)

New in JCMC with @bronwynec.bsky.social: People who feel more in control of their social media use tend to use it less and report better well-being. Seeing social media as positive was associated with more use, but not well-being. 👉 doi.org/10.1093/jcmc...
Abstract:

Building on the idea that subjective evaluations of social media use (SMU) may shape well-being effects, this study investigated how two “social media mindsets”—agency (perceived control over SMU) and valence (perceived effects of SMU)—relate to self-reported and logged SMU, and four well-being indicators (depression, anxiety, stress, and life satisfaction) in a South African sample of young adults (N = 1,858; M age = 21.01). Agency mindsets were negatively correlated with SMU and positively with well-being, while valence mindsets were associated with higher SMU but not with well-being. Logged SMU showed weaker associations with mindsets and well-being than self-reported SMU, suggesting differences between perceived and actual behavior. The findings replicate, extend, and in some cases contradict prior research, emphasizing how users’ sense of control is more important for well-being than SMU duration or perceptions of its effects, and that more work is needed to understand whether the “mindsets” concept is fruitful.

Lay summary:

This study investigated how young adults’ feelings about social media—whether they feel in control of their use (agency) or view it positively (valence)—relate to their actual use and mental well-being. The study involved 1,858 participants from South Africa using both self-reported and actual logged social media usage data. The results show that people who feel more in control of their social media use tend to use it less and report better mental well-being. In contrast, those who see social media as more positive spend more time on it, but this mindset did not directly relate to well-being. The data collected from logs of actual usage show weaker relations with well-being compared to people’s estimates and to their mindsets. These findings suggest that a person’s sense of control over social media plays a more important role in their mental health than how much time they spend on it.

The consensus paper deserves plenty of criticism. I won’t defend the process, how some have framed the findings, or claims that it represents a preponderance of evidence. I (naively?) contributed hoping to shape a more accurate view of the evidence, given how it might be used. t.co/7r6WQ6vCbm

Seeing that God is an Astronaut will be playing in The Netherlands next year prompted me to reconnect my Spotify account to my old last.fm profile. It's been such an amazing time capsule of old (and current) favourites.

While this partnership between Meta & @@cos.io is an exciting first-step in data access & transparency, let's hope in the long run this can go beyond a "a select group of academic researchers". Some data access is good, but more data access is better www.cos.io/meta

We're conducting some research on communication visibility in organisational/enterprise social media among public/transparent organisations. I saw this message today and for some reason found it to be quite funny in this context.

Excited to have received the "Early Career Researcher" award from Stellenbosch University. While there is only one name on the award, this should not be an individual prize, thanks to all of my collaborators, mentors, colleagues, students, friends, family for all of the support!

Its possible to do this with slack. If you're a channel owner you can export a folder for each public channel with a JSON file containing the messages for each day (and metadata). This can be easily parsed but I guess the tricky thing is access...I can't see any examples of 3rd party studies..
