Assessment of the Self-Determination of Spanish Students with Intellectual Disabilities and other Educational Needs.

The purpose of this study was to assess the self-determination of Spanish high school students with Intellectual Disability and other Special Educational Needs (SEN). A total of 371 students between 11 and 17 years of age participated in the study. Of these, 46.4% (n=171) presented SEN, specifically learning disabilities (n=97; 26.2%), borderline and intellectual disability with higher IQ scores (n=43; 11.6%) and mild intellectual disability (n=32; 8.6%). The remaining students without SEN made up the control group. The assessment was carried out using a translated and validated Spanish version of The Arc's Self-Determination Scale (Wehmeyer, 1995). This measure had appropriate psychometric properties. Students with SEN obtained significantly lower scores than their peers without SEN. However, no differences were found in relation to the type of SEN or, more specifically, in relation to the presence of intellectual disability. The educational implications of the results are discussed.
