Super excited to announce our paper on hierarchical inflammatory phenotypes of depression is out
@BiologicalPsyc1
! This is my favorite study to date, largely because it suggests a belief I used to have is wrong 1/8
I'm creating a training video on multilevel modeling, any favorite resources/tools for exploring fixed vs. random slopes conceptually and/or how to determine when random slopes are beneficial?
I'll start, I frequented to reorient myself to random effects
Been loving the causal inference resources for R at this site. Good breadth of coverage for people looking for something a little more hands-on than most of the resources I find.
Lovely ~systematic review~ on the assumptions of linear regression models in clinical psychology. Highly recommend looking through if you a) use regressions or b) review papers that use regressions (so, basically all of us).
Elated to have matched at McLean! HUGE thank you to everyone who has supported me through this process and so, so excited to take this final step toward becoming Dr. Moriarity.
I will be away from e-mail until Monday, May 23rd. Please excuse any delay while I am having the time of my life with the most beautiful woman, friends, and family in the world.

Phenotyping research has shown that many risk factors are not equally associated with all symptoms of a disorder. But, what does this mean for studies using sum/factor scores? We explore the consequences + some solutions in our new paper

Very honored to receive a
@UCLA
Chancellor's Award for Postdoctoral Research last night. The plaque is great but the real treat was having another opportunity to take my amazing team of RAs out to a very necessary thank you dinner.
It just hit me that, by the end this year, I will have spent damn near a quarter of my life in a PhD program and I tell you I did not breathe for at least 20 seconds.
Tired: Daniel P. Moriarity, MA
Wired: Daniel P. Moriarity, PhD
Blessed and thankful to my family, friends, colleagues, and mentors who supported me along the way.

Got what I think (?) is a fundable score on my F32 resubmission today, but I've been resisting letting myself celebrate until I heard back from my PO. Still haven't heard back, but decided to lean in and celebrate improvement and passion anyway. Cheers, ya'll!
So excited to finally be able to announce I will be doing a postdoc with
@UCLAStressLab
(and this wonderful team of postdocs)!!! George's Social Signal Transduction Theory was what sparked my interest in psychoneuroimmunology almost a decade ago. Dream come true!
Time for the big reveal for our new

After 4 submissions, I finally got a score below the payline for my F31. Regardless of what happens at council, it's so validating to know that I was able to improve my originally undiscussed submission into something that has a shot at being NIMH-funded. Dreams come true.
Where does one include "got dragged on reddit" on their CVπ

Finally, a core memory that should stop me using "ran" instead of "estimated" when describing my analyses.

I just reviewed what was without a doubt the best paper I've ever reviewed, recommended acceptance as is.
Looking forward to doing a thread on why I think it's so exciting once it eventually goes live.
"Although there are surely multiple contributors to the replication crisis in psychology, one largely unappreciated source is a neglect of basic principles of measurement. We consider 4 sacred cowsβwidely shared and rarely questioned assumptionsβin psychological measurement..."
Have really avoided getting into quality power analysis for HLM/MLM because it makes my head spin, but this shiny app + paper seem like a great jumping off point.

I did a soft launch into the job market this year and came up without any offers (womp). Despite all the discussion about the academic job market I've seen, two of my biggest take-aways were surprises to me, so I wanted to do a thread. 1/12
My prelim "Back to Basics: The Importance of Measurement Properties in Biological Psychiatry" is now live @ Neuroscience & Biobehavioral Reviews! A thread on the paper I've most enjoyed writing to date 1/15
Nothing like doing a systematic review to realize how many times authors claim that their paper is "the first to test X" when, in fact, their paper was not the first to test X.
New pre-print using moderated non-linear factor analyses to test inflammatory phenotypes in 5 data sets and almost 28,000 participants. TLDR; we find that CRP is simultaneously & uniquely associated with latent dep AND some individual sxs. 1/5

Huge congrats to everyone who did AND did not get an NSF GRFP this year.
People who did, CONGRATS. Badass way to start your graduate training! Find some time to soak it in and enjoy some self-care.
People who didn't, you EQUALLY deserve some positive reflection & celebration 1/
Useful primer on when a variable should be included as a covariate by thinking through whether it's a mediator, confounder, or collider. Great resource for intro stats.
Really excited to see this BEAST of a paper live & open access.
It's a friggin' tome, covering a ton of ground on Social Safety Theory that will hopefully be a reference point for people across fields who care about social safety, threat, and health. 1/2
Woke up to the news that we were awarded a

Teaching Grant for the

Meta-analysis (N=1,008) revealed poor overall reliability (mean ICC=.397). Test-retest reliability of activity in a priori ROIs in 11 common fMRI tasks collected in the Human Connectome Project (N=45) and the Dunedin Study (N=20) were poor (ICCs=.07-.49).
Very happy that "Back to Basics: The Importance of Measurement Properties in Biological Psychiatry" is now in press at Neuroscience and Biobehavioral Reviews! Will do a thread once it's live, but PsyArXiv has the accepted version.
Beyond grateful to

(as well as my consultation/sponsorship team incl.

I always gripe that Psych 101 is mostly a history of psych course, not an intro to the current field. So, I'd scrap most of what the syllabuses have to focus on orientations (behaviorism, cognitive psychology, etc) + dive deep into diff philosophies of behavior, + careers in psyc

Does anybody have any resources to suggest on what variables are necessary to remove before posting open data to a repository? Obviously contact information but I've heard others that weren't as common sense to me (e.g., birthdates, disease history, etc)

When you write a personal statement you are in a battle against a very busy person's attention span.
Using high level vocabulary is good, writing with brevity and clarity is often much better.

Solidarity post with everyone not on the job market having anxiety due to all of the job postings this year, wondering if there will be any when it's our turn π¨
A lot of talk re: science education this week and I gotta say if I could add 1 course into a PhD level curriculum it would be on data simulation. Pain in the ass to try to self-teach, but really helps unveil some of the deeper/more often glossed over parts of other stats courses
Does anybody else have a distinct avoidance-pattern for writing discussion sections? I can write work daily on a paper for weeks but I'll avoid starting the discussion for days out of fear I don't know how to tie the bow on a project I'm passionate about.
Question for those who write manuscripts in R markdown;
How do you recommend getting coauthor feedback without a tracked changes setting? Send the document in Word, get feedback, then paste edits into the Rmd?
