Original article: Fraley, R. C., Chong, J. Y., Baacke, K. A., Greco, A. J., Guan, H., & Vazire, S. (2022). Journal N-pact factors from 2011 to 2019: Evaluating the quality of social/personality journals with respect to sample size and statistical power.

Due to a “copy-and-paste” error, certain data presented for PSPB were incorrect in the initial published version of the article. The authors would like to alert readers to the following changes:
1. In Table 1, the Aggregate NF for PSPB was corrected from “200” to “139.” The PSPB values for columns NF 2015 to NF 2019 also contained errors. The table rows have been reordered and the correct values are indicated below in bold.
N-Pact Factors of Social/Personality Journals in Years 2011 to 2019
Note: N-pact factors (NFs) are computed as the median sample size of between-persons studies sampled from a journal for the year in question. We coded all studies from 20% of randomly sampled articles published in each journal for each year. The number of studies coded for each cell are reported in parentheses. All numbers are rounded. Journals are listed in descending order of their aggregate NF, as the median across the yearly NFs. JRP = Journal of Research in Personality; JP = Journal of Personality; EJP = European Journal of Personality; SPPS = Social Psychological and Personality Science; PSPB = Personality and Social Psychology Bulletin; JPSP = Journal of Personality and Social Psychology; EJSP = European Journal of Social Psychology; PS:S = Psychological Science (social/personality); JESP = Journal of Experimental Social Psychology.
2. In Table 2, the PSPB values under columns 2015 to 2019 contained errors. The table rows have been reordered and the correct values are indicated below in bold.
The Estimated Statistical Power of Studies Published in Social/Personality Journals in Years 2011 to 2019 to Detect an Average Published Effect Size (ρ = .20)
Note: Any value above 99% was rounded down to 99. JRP = Journal of Research in Personality; JP = Journal of Personality; EJP = European Journal of Personality; SPPS = Social Psychological and Personality Science; PSPB = Personality and Social Psychology Bulletin; JPSP = Journal of Personality and Social Psychology; EJSP = European Journal of Social Psychology; PS:S = Psychological Science (social/personality); JESP = Journal of Experimental Social Psychology.
3. In Table 3, the PSPB value for FDR if P(H0) = .80 under the 2019 column was corrected from “0.20” to “0.19.” The table rows have been reordered and the correct value is indicated below in bold.
Estimated False-Discovery Rates of Social/Personality Journals in Years 2011 to 2019, Assuming No p-Hacking or Questionable Research Practices
Note: The false-discovery rate (FDR) is the proportion of significant findings that are false positives. See the introduction for an explanation of this statistic. We calculate the FDR under the assumption that the null hypothesis is true 50% of the time and 80% of the time using sample-size information for the years 2011 and 2019. JRP = Journal of Research in Personality; JP = Journal of Personality; EJP = European Journal of Personality; SPPS = Social Psychological and Personality Science; PSPB = Personality and Social Psychology Bulletin; JPSP = Journal of Personality and Social Psychology; EJSP = European Journal of Social Psychology; PS:S = Psychological Science (social/personality); JESP = Journal of Experimental Social Psychology.
4. In the Results section, the last sentence in the “What is the relationship between journal impact factors and journal NFs?” subsection was incorrect. It was corrected from “In fact, the correlation is negative (–.08), although negligibly different from zero” to “In fact, the correlation is zero (.0006).”
5. The data point for PSPB in Figure 4 was incorrect. The corrected figure appears below.
The N-pact factor (NF) of journals plotted against their impact factor (2019). NF is based on the aggregate NFs from 2011 to 2019. JRP = Journal of Research in Personality; JP = Journal of Personality; EJP = European Journal of Personality; SPPS = Social Psychological and Personality Science; PSPB = Personality and Social Psychology Bulletin; JPSP = Journal of Personality and Social Psychology; EJSP = European Journal of Social Psychology; PS:S = Psychological Science (social/personality); JESP = Journal of Experimental Social Psychology.
