ABSTRACT
Assessing and promoting self-determination is a key educational component to improved outcomes for transition-age young, specially for students with significant support needs. However, there are no psychometric robust tools in the Spanish context to assess self-determination. The main aim of this study is to present the developmental of The ARC-INICO Self-determination Scale designed to evaluate self-determined behavior of students with intellectual disability and an exploratory study of its psychometrical properties. The scale was applied to 99 high school students with intellectual disabilities. On average, these students were 16 years old (range: 11-19). Adequate internal consistency was shown. The factor analysis supported the multidimensional structure proposed for the scale. A set of items were found for review based on discrimination index. In conclusion, initial analyses show the acceptable preliminary psychometrical properties of this measure, indicating that it’s followed the right path in the development of a tool to know the level of students in skills such as autonomy, self-regulation, empowerment or self-knowledge that will be essential in their process of transition to adulthood.
