Porter, T., Molina, D. C., Cimpian, A., Roberts, S., Fredericks, A., Blackwell, L. S., & Trzesniewski, K. (2022). Growth-mindset intervention delivered by teachers boosts achievement in early adolescence. Psychological Science, 33(7), 1086–1096. https://doi.org/10.1177/09567976211061109
The above article was issued a Preregistered Open Science badge; the Preregistration can be found at https://osf.io/cnhwj. Subsequent to publication, a reader of the article brought to the attention of the Editor in Chief that there were departures from the preregistered design and analysis plan that were not specified in the article. The Editor’s comparison of the article and the preregistration plan confirmed that this was the case. Upon contact, the authors of the article acknowledged the departures, explained the circumstances that contributed to them, and provided additional analyses that more closely followed the preregistered plan. Based on this information, the Editor in Chief determined that although the departures were numerous and substantive, they did not undermine the primary findings reported in the article.
It was further determined that in the Open Practices Disclose form used to apply for the Preregistered badge, the authors indicated that not all of the analyses described in the registered plan were reported in the article yet they did not specify which analyses were omitted and nor did they provide the requisite justification for the deviations. As such, the journal should not have awarded the Preregistered badge. Accordingly, the Editor determined that although the scientific contribution of the work remained, the Open Science badge for Preregistered should be rescinded. The authors agree with this decision.
The authors provide a summary of the deviations from the preregistration that were not reported in the manuscript, and potential effects on the primary findings reported in the article at https://osf.io/yn2pw. The summary also includes the results of additional analyses that followed the preregistration more closely, the net effect of which was to support the primary results as reported in the article.
