The present study aimed to investigate the effect of a social stories intervention on the social skills of male students with autistic spectrum disorder (ASD). The sample included 30 male students with ASD who were selected through convenience sampling and randomly assigned to an experimental group (n = 15) or a control group (n = 15). The social skills of both groups were assessed pre- and post-test using Stone and colleagues' Social Skills Scale (which included subscales for understanding/perspective-taking, initiating interactions, responding to interactions, and maintaining interactions). The experimental group participated in 16 sessions of social stories training, while the control group did not. Overall, the results showed that the social stories intervention improved the social skills of the children with ASD in the experimental group compared with the control group. The effects of the social stories intervention were mostly evident in the subscales for understanding/perspective-taking, initiating interactions, and maintaining interactions with others. The social stories intervention had no effect on the subscale assessing ability to respond to others. The study findings emphasize the effectiveness of the social stories intervention in improving the social skills of children with ASD, which may be used by teachers, parents, or professionals who work with such children.
