We hereby inform that a correction is needed in the article titled “Positive psychology interventions to improve well-being and symptoms in people on the schizophrenia spectrum: a systematic review and meta-analysis” (http://dx.doi.org/10.1590/1516-4446-2020-1164), by Pina et al., published in the Brazilian Journal of Psychiatry in December 2020 in ahead of print mode. The data from Shrank et al. 2015 (ref. 19 in the article) were mistakenly included in the metanalysis with values reported as mean and standard error (SE), rather than the correct mean and standard deviation (SD). Updating the values from SE to SD resulted in considerably reduced pooled effect sizes compared to the original metanalysis. Nonetheless, as discussed in the review, the results still favor positive psychology interventions for people in the schizophrenia spectrum, albeit by a very slight margin. Below we reproduce the revised, correct versions of the forest plots shown in Figures 2 and 3.
