Authors retract, replace highly cited paper on ADHD in kids

Researchers have retracted and replaced a 2014 paper in JAMA Psychiatry, exploring a new way to classify attention deficit hyperactivity disorder (ADHD) in children, after discovering errors in the data.

Some experts have criticized the current diagnostic criteria for ADHD—noting, in some cases, it could inflate the rate of diagnosis. Sarah L. Karalunas, the paper’s corresponding author, told Retraction Watch that the aim of the study was to look beyond current criteria and “demonstrate an approach that could be used to better delineate the boundaries of ADHD and other psychiatric diagnostic categories.”   Continue reading Authors retract, replace highly cited paper on ADHD in kids

Authors retract, replace highly cited JAMA Psych paper for “pervasive errors”

JAMA PsychiatryAuthors have retracted a highly cited JAMA Psychiatry study about depression after failing to account for some patient recoveries, among other mistakes.

It’s a somewhat unusual notice — it explains that the paper has been retracted and replaced with a new, corrected version.

The study, which included 452 adults with major depressive disorder, concluded that cognitive therapy plus medication works better to treat depression than pills alone. But after it was published, a reader pointed out that some of the numbers in a table were incorrect. The authors reviewed the data and redid their analysis, and discovered “a number of pervasive errors.”

The notice (termed “notice of retraction and replacement”) explains the consequences of those errors:

Journal retracts — and republishes — small study on gamma rays for OCD

Screen Shot 2015-10-28 at 8.40.00 PMJAMA Psychiatry has retracted and republished a paper on a cutting-edge procedure for patients with obsessive compulsive disorder.

In the original paper, the authors claimed that three out of eight patients who underwent a procedure that used gamma rays to kill brain cells showed improvements 12 months later (versus zero in the group who underwent a “sham” procedure). But after a reader noticed an “inadvertent” error in the calculation of how many patients had improved, the authors realized that only two of the patients had responded meaningfully to the procedure.

The new results “did not reach statistical significance,” the authors write in a “Notice of Retraction and Replacement.”  JAMA Psychiatry published it yesterday, along with a new version of the article, a letter from psychiatrist Christopher Baethge pointing out the error, and an editorial. The original article is available in the supplemental material of the new version, with the errors highlighted.

Here’s the note in full for “Gamma ventral capsulotomy for obsessive-compulsive disorder: a randomized clinical trial,” which explains the error:
