This study examined the application of SST in order to enhance social skills in an adolescent with autism spectrum disorder (ASD). The research was conducted using single-case experimental design with pre and post within subject design. The participant of the study was a fourteen-year-old student who had been diagnosed with autism spectrum disorder and had difficulties in social interactions in school. Measurements were taken before and after the intervention program through interviews, observation, and autism social skills profile (ASSP) questionnaire. Before interventions were conducted, the participant was unable to differentiate between sarcasm and compliment, responding to others? emotions with neutral facial expression, couldn't express her feelings, and couldn't say 'no' to friends? invitation or order. The results of this study indicate that SST could enhance social skills in an adolescent with autism spectrum disorder (ASD). The participant became more aware of social clues that indicated sarcasm or compliment, responding to others? stories with empathic statements, able to express her feelings to close friends, and able to say ?no? to friends? invitation or order.
