 A corrigendum on Ten year neurocognitive trajectories in first-episode psychosis by Barder, H. E., Sundet, K., Rund, B., Evensen, J., Haahr, U., Hegelstad, W., et al. (2013). Front. Hum. Neurosci. 7:643. doi: 10.3389/fnhum.2013.00643 neurocognition psychosis spectrum disorders first-episode longitudinal studies neuropsychiatry

A small part of the data on five of the 43 patients was accidentally displaced in the data file, which affected two of the results presented in the original manuscript.

The statistical significance of the MANCOVA (controlling for IQ and education) is not statistically significant. However, the effect size is still substantial (η2 = 0.444). The Motor Speed index does not show a statistically significant interaction with relapse-group, leaving Figure 4 redundant. A few minor changes in the decimals are added to Tables 1, 3.

The four neurocognitive indices with the corresponding subtests and raw scores at each time point for the follow-up sample (Corrected numbers in red).

CVLT, California Verbal Learning Test (Delis et al., 1987, 2004); FTT, Finger tapping test (Lezak, 1995); WCST, Wisconsin Card Sorting Test (Heaton et al., 1993); COWAT, Controlled Oral Word Association task (Spreen and Strauss, 1998).

Results from MANOVA; effects of early relapse on neurocognitive indices over time (Corrected numbers in red).

aTotal relapses first year: “No relapse first year” (N = 31), “Relapse(s) first year” (N = 12).
