In the article “A Meta-Analysis of Cognitive Remediation in Schizophrenia” (Am J Psychiatry 2007; 164:1791–1802) the following corrections should be noted:
1) In Table 1, the Independent Living Scale-problem solving assessment should be listed with the “Cognitive measures lacking consensus” rather than within the “Reasoning and problem solving” domain.
2) Reference 51 should have cited the following study: Medalia A, Revheim N, Casey M: Remediation of memory disorders in schizophrenia. Psychol Med 2000; 30:1451–1459
3) In Table 2, in the column titled “Cognitive Effect Size” the cognitive effect size for verbal learning and memory for treatment 2 of the Medalia et al. study should be –0.39 instead of 0.39. However, the correct effect size (–0.39) was used in the meta-analysis calculations presented in the review.
4) In Table 2, the program type for Penades et al. (2006) should be listed as “Drill and Strategy Coaching” instead of “Drill and Practice.” However, the correct program type was entered in the meta-analysis calculations presented in the review.
