Individuals with autism spectrum disorders (ASD) often present with difficulty in sustaining engagement, attention, and have disruptive behavior in classroom settings. Without appropriate intervention, these challenging behaviors often persist and negatively impact educational outcomes. Self-monitoring is a well-supported evidence-based practice for addressing challenging behaviors and improving pro-social behaviors for individuals with ASD. Self-monitoring procedures utilizing a handheld computer-based technology is an unobtrusive and innovative way of implementing the intervention. A withdrawal design was employed to assess the effectiveness of a technologically-delivered self-monitoring intervention (I-Connect) in improving on-task and task completion behaviors and decreasing disruptive behavior with four adolescents with ASD. Results demonstrated improvements in on-task and task completion behaviors across all four participants and disruptive behavior improved for two participants.
