Introduction: Occupational therapists use not only standard strategies but technology also as a form of intervention for children with autism spectrum disorder. One of the possible ways of using technology is to use it for video modeling. Video modeling is a form of therapy that improves the performance of basic activities of daily living in children with autism spectrum disorder. Purpose: The purpose of this thesis was to evaluate the effectivness of using video modeling in occupational therapy to improve performance of basic activities of daily living in child with autism spectrum disorder. Methods: This case study was conducted within six weeks period. Participant was 7-years old girl with autism spectrum disorder. Twice a week she performed basic activities of daily living as they were presented on the video clips. Video modeling consists of choosing the right activities for intevention and of identifying actions within each activity. Video clips demonstrated correct, specific performance of activity and of verbal instructions. Assessments with WeeFim, Activity analysis by skills and Pediatric volitional questionnaire were used in the beginning and in the end of occupational therapy. Results: Improvement occurred in klient's independence (WeeFim: first evaluation 95 and the last evaluation 98). Processing (is paying attention/is focused, uses/handles objects, begins, performs continuously, performs in the right order, finishes, directs movements, changes performance, notices/responds, gains) and motor skills (coordinates, regulates) improved. Pediatric volitional questionnaire results show improvement of volition to perform basic activities of daily living. Discussion and conclusion: Six weeks case study showed that video modeling is an effective intervention strategy and can be used to improve the performance of basic activities of daily living in children with autism spectrum disorder, who are capable of imitating other people and have ability to understand instructions.
