Three adolescents with moderate to severe intellectual disabilities who attended a clinical setting participated in this study. The effects of repeated times practice for component skills on the emission frequency of composite daily living skills such as wearing a shirt, shoes, fastening buttons, and using an iPad were investigated. We practiced the Big 6 + 6 integrated with component skills involving legs and feet and the "swipe" movement. We used five simple time-series designs to measure the intervention's effects. The findings show that participants increased the frequency with which they emitted composite skills. They have become less reliant on their caregivers' care and have gained more independence at home and in the community.
