Self-determination in adolescents and adults with intellectual and developmental disabilities

The importance of self-determination to wellbeing and life satisfaction has been established by research in motivation and education. The present review provides a synthesis of research in these areas at a time when the two lines of research are converging.

Research has established that youth and adults with intellectual and developmental disabilities (IDD) are not as self-determined as their nondisabled peers and that this negatively impacts the quality of their lives. Further, research has established the positive benefits of a focus on self-determination assessment and intervention for people with IDD. Recent studies illustrate the shifting focus to a life-course development perspective of self-determination and the alignment of assessment and interventions with that perspective. Research on self-determination and IDD outside of the United States has dramatically increased.

Research shows that people with IDD who are more self-determined achieve more positive school and adult outcomes and higher life satisfaction. Assessment of and interventions to promote self-determination have increasingly emphasized all people and are aligning with research in motivation and positive psychology. This provides a foundation for promoting greater community, school, and work inclusion.
