This study examined differences in self-determination among students with autism spectrum disorders (ASD), students with intellectual disability (ID), and students with learning disabilities (LD). A total of 222 participants with an equal size group for each of the three disability categories were selected to participate in the comparison of total…

Given the emphasis on promoting self-determination in the field of special education and the corresponding use of scales to measure self-determination in research and practice, it is important to examine whether widely used self-determination assessments measure the same constructs among and between students from different disability categories.…

Promoting self-determination has been identified as an important practice for the successful transition of youth and young adults with disabilities, and numerous studies have examined the relationship between levels of self-determination and transition-related and postsecondary outcomes. Only a few such studies, however, have examined the global…

The purpose of this article is to describe preliminary psychometric characteristics of a student self-report measure of self-determination, the "Self-Determination Inventory: Student Report" version (SDI-SR), designed for youth with and without disabilities. We administered the draft assessment to 311 youth and examined item functioning…

Promoting student self-determination is recognized as a key component of effective transition supports and services for youth with disabilities. This study examined differences in teacher perceptions of student capacity and opportunity for self-determination over the course of an academic year based on teacher assignment to a treatment group that…

Promoting the self-determination of adolescents with disabilities has become best practice in secondary education and transition services, but to date there have been no studies establishing a causal relationship between efforts to promote self-determination and enhancement of the self-determination of youth with disabilities. This article reports…

Promoting self-determination has been identified as best practice in special education and transition services and as a means to promote goal attainment and access to the general education curriculum for students with disabilities. There have been, however, limited evaluations of the effects of interventions to promote self-determination on…

Previous research has suggested differences in the locus of control (LOC) orientations of students with intellectual disability, learning disabilities, and no disabilities, although this research has been characterized by methodological limitations. The purpose of this study was to examine the development of LOC orientations in students with…

Promoting self-determination has become a best practice in special education. There remains, however, a paucity of causal evidence for interventions to promote self-determination. This article presents the results of a group-randomized, modified equivalent control group design study of the efficacy of the Self-Determined Learning Model of…

This article examines the impact of multiple individual and ecological factors on the self-determination of students with learning disabilities, mild and moderate mental retardation, and other health impairments. Baseline data from a multistate, longitudinal research project evaluating interventions to promote self-determination were examined…
