Applying Developmental Pscyh theory and research on adolescent emotion & regulation, parent-child interaction dynamics to more robust and informative understanding of youth digital experiences
Great use of state space grids!
I've wanted to look at mutual sensitivity (consistency between caregivers in their sensitivity) for years, and this analysis was buoyed by encouragement at @affectscience.bsky.social 2023 after a flash talk exploring the method. Thanks to @tomhollenstein.bsky.social for state space inspiration!

Yes, they were soooo close with 100 days and DSEM and then just neglected the one direction/path that would have given them an iota of leverage in interpretation. Could never get published if only WB-->SM path analyzed.
And then the follow-up schlock balloons to sure, it ain't an RCT.

Agreed, Andrea. That direction is never considered by the pre-convinced crowd.
aaannnndd....PANAS is not a wellbeing measure. Feeling negative emotions is NORMAL.
Please please please MAKE THE SCHLOCK STOP!

That’s not a fair interpretation of these results. Setting all other method issues aside, it’s just as likely that kids spend more time on their phones on days when they’re bored or “less happy” in some other way.

If only adults could pay attention to something other than teenagers’ phones…
Today I note how, after Florida implemented their #cellphoneban in schools, Florida's national standardized testing scores dropped.
We need to work harder to improve schools by improving schools, not by banning technology.

As an expert, it really was not difficult to catch the bs. But students I gave it to all took it as real.
I am using this paper in all my classes as a cautionary tale.
The good news is, it makes another argument for critical thinking skill development.

Yup. You guessed it. NONE of the 45 references are real!
In journal, Scientia Psychiatrica, is out of Indoinesia, other papers seem legit. Editor did not respond to my email inquiry.

all studies were from the past 5 yrs w/ very large samples N>800). I know this literature, recognized none.
I did not notice 1-45 superscript in table title indicating that the 45 studies were referenced numerically.
and citations in text were just those 45
ok, let's look at the references.

No such institution exists anywhere in the country.

So...my undergrad thesis student is doing a quality analysis of studies found in meta-analyses. She identified a few and we contacted the authors to request their effect sizes and other variables for the studies in their papers.
