Original paper


Trial interventions in DIR and ABA with twin brothers with autism were offered to help the parents choose one of the programs for their sons. Pre- and post-test scores on the Communication and Symbolic Behavior Scales (CSBS) revealed a slight gain in the composite score of the ABA child and a slight loss in the score of the DIR child. Contrasted gains and losses occurred in six of the seven CSBS clusters. Results from this pilot research are discussed with additional communication and behavior data from the intervention period. Careful interpretation of CSBS outcomes in counseling parents and graduate students is strongly advised. Continued research in comparative outcomes for intervention programs is strongly encouraged.
