Social media ~ mental health meta-analysis:

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.

We might be at a stage where systematic reviews without checks of trustworthiness become a problem in itself - even a danger to patients, as these reviews are considered as highest level of evidence and the foundation of guidelines and clinical practice
Currently busy with updating a systematic review and have the impression that the flood of "clinical studies" from certain countries is intensifying - results too good to be true: enduring effects (usually uncommon), no drop-out, perfectly balanced sample sizes etc.

Presenting on different roles + steps in the publication process at journals- realizing I don't actually understand how regular submissions are grouped into issues + the extent that this is thematic vs. first-in is first-out.
Imagine this varies by journal- any pointers to include in my slides?

My impression is that Latent Class Growth Analysis is usually not that informative (or maybe I just don’t get what information we’re learning). Does anyone know a good critical paper on this? #stats #psyscisky

In our rejoinder, we argue 1) Dark terminology isn't used responsibly as BL et al. claim, 2) the term can be replaced with a more sensible and scientific one, 3) data support our position (Stanton et al., 2025), and 4) popularity ≠ importance. @davidchester.bsky.social @drlynam.bsky.social

Honestly this came as a bit of a surprise in my 1st RR experience. Figured the Stage 1 was necessary for evaluators to compare the published work to (a la pre-reg), so we've just uploaded the Stage 1 to OSF and referenced in the Stage 2 manus
From my experience, journals generally don't publish stage 1 of a Registered Report after in principle acceptance. But here, it seems Wiley does this? authorservices.wiley.com/author-resou... Can anyone point to examples for journals publishing stage 1 and then updating at stage 2, Wiley or other?
