The original version of this article unfortunately contained a mistake. In the last paragraph of the Results section under Effects of Training Interventions on Implementation Fidelity, the last sentence should read as follows: The results indicated higher implementation fidelity in the IMP-SUPPORT condition classes (mean = 0.15, SD = 0.87) relative to the REGULAR classes (mean = −0.22, SD = 1.14; p < 0.05).
