Examining Individual and Instruction-Related Predictors of the Self-Determination of Students with Disabilities: Multiple Regression Analyses.

This study examined individual and instructional predictors of the self-determination of students with disabilities, as measured by The Arc's Self-Determination Scale and the AIR Self-Determination Scale, Student version. The general findings indicated that instructional, knowledge and dispositional factors predicted students' self-determination over personal predictor variables. In particular, self-efficacy and outcome expectancy scores, student-directed transition planning instruction, and students' pre-intervention transition planning knowledge predicted higher students' self-determination.
