The present study aimed to examine the effectiveness of a multi-component intervention on cooperative behaviors in children with autism spectrum disorder (ASD). In this study, three dyads comprising six boys aged between 4.5 and 7 years with ASD participated, following a randomized multiple baseline design. The participants were asked to construct models together using toy sets. The visual analysis and randomization test (p < 0.01) showed that the intervention increased cooperative behaviors for all six participants, and improvements were maintained after the intervention components were terminated. Four participants in two dyads demonstrated generalization to three new toy sets. For the remaining two participants, the interdependent group contingency was reintroduced in order for them to demonstrate cooperative behaviors.
