This study was conducted at a nonprofit organization whose mission is to provide responsive, caring, and effective services to children with autism. The purpose of this study was to analyze the effects of D.A.N.C.E. training on teaching interactions, harmonious engagement, instructional engagement, and progress on child goals for two early and intensive behavioral intervention (EIBI) staff and the children in their care. A multiple baseline design was employed to evaluate the effectiveness of the training. Results indicated that staff increased teaching interactions and maintained instructional engagement; that children increased target goal responses; and that harmonious engagement between the two increased for both dyads. These results are discussed in the context of measurement, training, and social validity.
