Secondary data analysis was used to develop and examine disability-related differences in outcome constructs from the National Longitudinal Transition Study-2 (NLTS2). Findings suggest that outcome constructs could be created that represented key elements of quality of life domains including social relationships, financial independence, financial…

Data from the National Longitudinal Transition Study-2 (NLTS2) were used to examine the impact of three personal factors--race/ethnicity, gender, and family income--on self-determination (i.e., autonomy, psychological empowerment, self-realization) and early adulthood outcome constructs. Findings suggest for those with high incidence disabilities,…

Secondary data analysis using the National Longitudinal Transition Study-2 dataset was conducted to examine the degree to which autonomy, psychological empowerment and self-realization (three of four essential characteristics of self-determination) play a mediating role in the relationship between school-based factors and postschool outcomes. The…

This study conducted secondary analysis of data from the National Longitudinal Transition Study-2 (NLTS2) to examine the degree to which student, family, and school constructs predicted self-determination outcomes. Multi-group structural equation modeling was used to examine predictive relationships between 5 students, 4 family, and 7 school…

This study examined the convergent validity of the "Supports Intensity Scale-Adult Version" (SIS-A; Thompson et al., 2015a) and "Supports Intensity Scale-Children's Version" (SIS-C; Thompson et al., 2016a). Data from SISOnline (n = 129,864) for the SIS-A and from the SIS-C standardization sample (n = 4,015) were used for…

This study examined similarities and differences in measurement properties and score comparability of the "Supports Intensity Scale-Adult Version" (16-64 years) and the "Supports Intensity Scale-Children's Version" (5-16 years). Data were collected from 142 adolescents with intellectual disability with both versions of the…

This study examined, using data from the National Longitudinal Transition Study-2, the impact of constructs associated with self-determination (i.e., autonomy, self-realization, and psychological empowerment, measured while youth were in secondary school) on postschool (a) employment and payment/benefits, (b) education, (c) independent living, and…

The purpose of this study was to use data from the National Longitudinal Transition Study-2 to (a) conceptually identify and empirically establish student, family, and school constructs, (b) explore the degree to which the constructs can be measured equivalently across disability groups, and (c) examine latent differences (means, variances, and…

This article introduces the Supports Intensity Scale-Children's Version (SIS-C) designed and normed to be used with children across multiple contexts, including home, school, and community life. Steps taken to develop the scale are described, and findings from data collected on a field test version of the SIS-C are shared. Preliminary findings in…

Data from the National Longitudinal Transition Study-2 (NLTS2) were used to examine (a) the aspects of self-determination assessed in NLTS2 and (b) measurement equivalence and latent differences across the 12 disability categories recognized in IDEA. Three of the four essential characteristics of self-determination - autonomy, self-realization,…

This study explored the effects of a web-based decision support system ("Tutorial") for writing standards-based Individualized Education Programs (IEPs). A total of 35 teachers and 154 students participated across two academic years. Participants were assigned to one of three intervention groups based on level of "Tutorial"…

This paper uses a social-ecological lens to examine self-determination research, attempting to organize what is known (and unknown) about contextual factors that have the potential to impact the development and expression of self-determined behavior in individuals with disabilities across multiple ecological systems. Identifying and categorizing…
