The effectiveness of behavioral interventions for the treatment of young children with autism has been well documented in professional literature. The success of these procedures, however, depends on the fidelity of implementation and proper training of the therapist. The purpose of this study was to evaluate a 125-skill, comprehensive staff training package that involved a graduated sequence of teaching. In addition to changes in skills, social validity and training time were also assessed. Results indicate that correct demonstration of skills increased following training, incorrect implementation decreased, teachers rated the procedures favorably, and the total training took between 20 and 32.5 hours for over 120 skills to reach mastery criteria. A discussion of the results as well as implications for future research is also provided. thank Jesus Rosales-Ruiz, Rick Smith, and Nicole Zeug for their amazing feedback and generosity in agreeing to be on my thesis defense committee. Your contribution and feedback was truly appreciated. An additional thank you to Nicole Zeug for providing extensive support and assistance throughout the entire process. I would also like to thank Murray Sidman for his kind and encouraging comments in the earliest stages of this project. I will be forever grateful to the friends I have made at UNT and their support throughout the last three years; the friendships we have formed are ones I will never cease to value. Of all of my classmates, Claire Anderson has been especially supportive. Through your assistance in the tedious task of scoring videotapes and ongoing support of the entire process, I will be forever grateful. We started and ended this phase of our lives together and our friendship is one that will not be forgotten.Finally I would like to thank the trainees that participated in the study, including Donna Ludlum, Mona Alhaddad, Donna Townley-Cochran, and Megan Thompson. I appreciate your willingness and excitement throughout the training process. Smith, Jahr, & Eldevik, 2002;Howard, Sparkman, Cohen, Green, & Stanislaw, 2005;Lovaas, 1987). It has also been documented that outcomes can be maintained over long periods of time (Eikeseth, Smith, Jahr, & Eldevik, 2007;McEachin, Smith, & Lovaas, 1993).
ivThe success of these procedures, however, depends on the fidelity of implementation (Bibby, Eikeseth, Martin, Mudford, & Reeves, 2002). There is evidence that children learn better when interventionists are appropriately trained (e.g., Ala'iRosales, Thorisdottir, & Etzel, 2003;Downs, Downs, & Rau, 2008).Therefore, the effectiveness of treatment for children with autism appears to rely heavily on the need to have adequate training for persons responsible for implementing these techniques (Jahr, 1998;McGee & Morrier, 2005; National Research Council, 2001; Shook, Ala'iRosales, & Glenn, 2002). Table 1 provides an overview of reviews and empirical literature illustrating the importance of training for change agents.Early research has shown that it is possible, and necessary, to empiri...
