The "Self-Determination Inventory--Student Report" (SDI-SR) was developed to address the need in the field for new, theoretically aligned measures of self-determination. The purpose of this study was to establish the most robust and efficient set of items to assess the self-determination of adolescents with and without disabilities on…

The Self-Determination Inventory: Student Report (SDI:SR) was developed to address a need in the field for tools to assess self-determination that are aligned with current best practices in assessment development and administration, and emerging research and best practices in promoting self-determination. The present study explored patterns of…

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…

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 self-determined learning through student-directed learning strategies has been documented to promote more positive school-related outcomes for upper elementary grade learners with disabilities and other students who are struggling. These strategies are typically introduced in multicomponent interventions combining several…

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…

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…

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…

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…

The purpose of this study was to assess the self-determination of Spanish high school students with Intellectual Disabilities 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%),…

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…

Expectations for the future of students with mental retardation (n=93), learning disabilities (n=158), or students without disabilities (n=178), were examined. Students with mental retardation were significantly less hopeful than were their peers with learning disabilities or without disabilities. Students with learning disabilities were less…

The psychometric properties of the Hopelessness Scale for Children (A. Kazdin et al., 1983) were examined for children and adolescents with mental retardation or a learning disability. Analyses of scores from 261 students shows a factor structure almost identical to the original structure and scale scores of adequate validity. (SLD)

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…
