There was an error in the article “Temperamental Correlates of Disruptive Behavior Disorders in Young Children: Preliminary Findings.” Dina R. Hirshfeld-Becker, Joseph Biederman, Stephen V. Faraone, Heather Violette, Jessica Wrightsman and Jerrold F. Rosenbaum. which appears on pages 563–574 of Biological Psychiatry, Vol. 50, No. 8.
Because of a programming error, the classification of the 4-year-old subjects in our sample as behaviorally disinhibited (BD) did not take into account whether the children showed minimal delays in carrying out unusual or socially unacceptable requests, as described in the Methods section. Therefore, our paper, as published, classified 4-year-old subjects as disinhibited based only upon having made more spontaneous comments than 75% of their age mates. When the analyses in the report were repeated incorporating minimal delays into the classification system as well, the results were nearly identical to those published. The only substantive differences were as follows: 1) the previous trend association between BD and male gender reached significance (X2 = 6.15, p = .046); 2) the comparison of rates of (ADHD) between the BD and non-inhibited-non-BD group lost significance, although the contrasts between the BD group and all others and the BD and (BI) groups retained significance; 3) the association between major depressive disorder (MDD) and disinhibition (comparisons between BD versus non-BD-non-BI children and BD children versus all others) gained significance; 4) the comparison between rates of comorbid disruptive behavior disorder plus mood disorder in disinhibited children versus all others dropped to trend significance (although the comparison with non-inhibited-non-disinhibited children remained significant), and 5) the association between BD and disruptive behavior disorders (vs. all others) lost significance when mood disorder was covaried.
