In the article1 that appeared on pages 16-24 of the January/February 2017 issue, one of our variables was mislabeled in the data set. Data related to the Hopkins Verbal Learning Test-R delayed recall variable was thus reported incorrectly. There were statistically significant results for this variable that were initially reported as being not significant. Here is how it should have appeared:
Abstract: The sentence "They also demonstrated significant improvements on neurocognitive tests of attention, learning, and executive functioning, which were 3 of the cognitive domains targeted in CCT" should read:
"They also demonstrated significant improvements on neurocognitive tests of attention, learning, memory, and executive functioning, which were 4 of the cognitive domains targeted in CCT."
Results: The portion "There were significant 2-way interactions of time by group on WAIS-IV Digit Span, the HVLT Learning, and D-KEFS Letter Fluency, with Veterans in the CCT group demonstrating a significant increase in scores (ie, improved performance) compared with those in the control condition. There were trends for group by time interaction on the HVLT-R Memory and UPSA-Brief, indicating improvement in the CCT group relative to the UC group that did not reach statistical significance" should read:

Discussion: The sentence "In addition, Veterans who participated in CCT demonstrated significant improvements on neurocognitive tests of attention, learning, and executive functioning, 3 of the cognitive domains targeted in CCT" should read:
"In addition, Veterans who participated in CCT demonstrated significant improvements on neurocognitive tests of attention, learning, memory, and executive functioning, 4 of the cognitive domains targeted in CCT."
Table 4: "Hopkins Verbal Learning Test-R delayed recall retention (memory)" should read:
"Hopkins Verbal Learning Test-R Delayed Recall (memory)."
The data for this row are incorrect and should read:
Table 5: "HVLT-R Retention T Score" should read:
"HVLT-R Delayed Recall (memory) T Score."
The data for this row are incorrect and should read:
The author regrets the error.
