Paper in a key area of my methodological work, so it was really interesting. But I really needed to get stuck in.

Two collaboration projects on the design and reporting of #RCTs that might be useful for others:

https://pubmed.ncbi.nlm.nih.gov/37982521/
presents 19 factors to aid trial design, and the DELTA2 Guidance specifying a target difference and reporting the #SampleSize calculation for RCTs
https://trialsjournal.biomedcentral.com/articles/10.1186/s13063-018-2884-0

#StudyDesign

Which #SampleSize to use in your pilot or feasibility trial?

Well, you won't find the answer in this review of studies in #ISRCTN (2013 to 2020)
https://pilotfeasibilitystudies.biomedcentral.com/articles/10.1186/s40814-023-01416-w

But it is a good intro into the topic, and with 57% not reaching their target sample size, they may interestingly not provide the information they were designed to offer!

A well-justified epistemological foundation is a key requirement for a #DelphiStudy:
https://www.sciencedirect.com/science/article/pii/S1865921722000769

The team argues that #ReportingGuidelines encourage researchers to reflect on and disclose key assumptions and methodological choices in such studies.

Mirjam Stieger (Lucerne Uni) and I are invited to present

at @unibern

This is the annual Summer Course of the Doctoral Program Brain and Behavioral Sciences, and comprises a mixture of keynotes, masterclasses, hidden curriculum etc.

I am very much looking forward to it, and also very honoured to be invited once again to Bern to train #ECRs!

One member of the FDA advisory committee, and non-voting, industry rep worked on Spravato for Jansen. Her colleague, a psychiatrist was MAPS-trained and works with ketamine currently. Let’s talk conflict of interests. What #psychiatricmedicines have been tested against the gold standard of cognitive behavioral therapy? Which of the providers in the #mdmaassistedtherapy trials or advisory meeting actually practice CBT? #studydesign #litreview #contactus

Call for #GlobalHealth #GlobalMentalHealth researchers interested in #Multimorbidity:

9th GACD Funding Call – Management of Multiple Long-Term Conditions
https://www.gacd.org/funding/current-call-for-applications/management-of-multiple-long-term-conditions
🗓️ 15.05. (first stage)

The common call document [pdf https://www.gacd.org/perch/resources/admin/ninth-gacd-call-text-mltc-wp-v1-5.pdf] lists a range of topics such as #StudyDesign, health #equity, stakeholder engagement and knowledge sharing it has a specific section on #OutcomeMeasures that explicitly refers to our COSMOS work
https://www.medrxiv.org/content/10.1101/2024.01.29.24301589v1

#CoreOutcomeSet

I'll be offering an introduction to #simulation methods to determine #SampleSize-s for clustered / nested studies.

Apparently another popular session at #RMeF23 🙇

One of the classics that got me into this area is Ukoumunne's
https://onlinelibrary.wiley.com/doi/abs/10.1002/sim.1330

I was always interested in how to straddle the overlap between observational #TherapistEffect studies* and #RCTs in this area.

#Rstats #StudyDesign

* eg., https://rdcu.be/dqi20

One of the most problematic areas in the submission we get and papers I review are the sections on #SampleSize justifications.

See for example @lakens' excellent paper on the topic:
https://psyarxiv.com/9d3yf/
It now comes with a process guide in a #ShinyApp, which is an excellent support:
https://shiny.ieis.tue.nl/sample_size_justification/
#Rstats

For #HRQL researchers:
https://rdcu.be/dnfO4

And many people teach this stuff, e.g., ☺️

#StudyDesign #NightshiftEditor
[edit: typo in hashtag]

A #SysReview from the "#ResponseShift – in Sync Working Group" analysed 150 studies
https://link.springer.com/article/10.1007/s11136-023-03495-x

Apart from the interest in the psychological phenomenon, the relative size of such effects compared to intervention effects (e.g., in #RCT https://link.springer.com/article/10.1186/s41687-022-00510-6) is very important for #StudyDesign in #HRQL research (see also https://doi.org/10.1007/s11136-023-03347-8).

Therefore an interesting descriptive finding: it was possible only for 105 of these studies to calculate #EffectSize-s.

@ncrav

While not expressing disagreement or agreement with the #study's #conclusions, the #experiment design included some features that make it difficult to #generalize from.

For example, they eliminated those homeless with a history of #substance #abuse. That by itself makes the #headline claims a bit suspect, or at least not clearly #supported by evidence.

The "Reviewer's guide to #QuantitativeMethods" provides a concise summary of what to learn about and how to plan & report studies employing 31 (2nd ed. apparently 35) methods: https://www.routledge.com/The-Reviewers-Guide-to-Quantitative-Methods-in-the-Social-Sciences/Hancock-Stapleton-Mueller/p/book/9781138800137

Since it is a book, it will be difficult for many to get access. Does anyone know whether at least the checklists have been published somewhere #OpenAccess?

And is there a #QualitativeMethods version?
