Retraction notice to: “Neural Indicators of Anhedonia: Predictors and Mechanisms of Treatment Change in a Randomized Clinical Trial in Early Childhood Depression” by Deanna M. Barch, Diana Whalen, Kirsten Gilbert, Danielle Kelly, Emily S. Kappenman, Greg Hajcak, and Joan L. Luby, in Biological Psychiatry 2019; 85:863–871.
This article has been retracted at the request of John H. Krystal, MD, Editor of Biological Psychiatry, with agreement from all authors. See Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).
The authors discovered an error in the scoring of the ERP data in this article. Specifically, the ERP in the authors’ acquisition and processing stream is live referenced to CZ, and then should be re-referenced in post-processing to TP9 and TP10, as described in the paper. However, the authors discovered that they had accidentally continued to include Cz along with TP9 and TP10 in the template to re-reference the ERP data in post-processing.
The authors reprocessed all of the data with only TP9 and TP10 in the referencing, as originally described in the manuscript, and then re-ran all of the analyses. The majority of the key results remained the same in terms of significance and interpretation. The results continue to show that children in PCIT_ED show a greater increase in RewP as a function of treatment than the waitlist group; however, the correlation with the corrected data is in the same direction, but reduced in magnitude and no longer significant. Thus, a greater change in RewP is no longer significantly associated with a greater reduction in MDD symptoms.
This error affects the abstract, results, Table 2, Figures 1–3, discussion, and supplement.
The authors voluntarily informed the Journal of this honest error upon its discovery. Because of the extent and nature of the changes to the paper, the editors and authors concluded that, to ensure maximum clarity and transparency, the only course of action was to retract this version of the paper. The authors revised the paper, which went through additional peer review. The new version was accepted and has been published: 10.1016/j.biopsych.2020.06.032.
