Secondary data analyses occur when new analyses are proposed for existing data. Although they are prevalent in special education research, there is little guidance on how to prepare secondary data analyses studies. Preregistration of secondary data analyses studies provides a nice opportunity and structure for fellow researchers to share…

In this preregistered study, we confirmed a transition-planning construct and determined its relationship with an established economic-hardship construct using parent- and youth-reported data from the National Longitudinal Transition Study 2012 and following established quality indicators of preregistered secondary data analyses studies.…

The purpose of the current study was to conceptually replicate a multi-indicator construct of economic hardship in a national sample of adolescents with and without disabilities (N = 9,230). Using data from the National Longitudinal Transition Study 2012 (NLTS2012), the latent construct economic hardship was confirmed from six theoretically…

In this study, we examined college and career readiness (CCR) support for students with and without disabilities using data from the National Longitudinal Transition Study 2012. We selected variables relevant to CCR and focused on the interaction of disability, race and ethnicity, and household income across a range of disability categories,…

The purpose of this study was to draw from self-determination and self-efficacy theories to evaluate psychological constructs (autonomous motivation, competency, and outcome expectancy) as mediators of the relationship between working alliance and engagement in transition-vocational rehabilitation (VR) services among African American students with…

We tested the efficacy of a comprehensive intervention program designed for high school students across the autism spectrum, the Center on Secondary Education for Students with Autism (CSESA) model, in a cluster randomized control trial involving 60 high schools in three states (California, North Carolina, Wisconsin), with implementation occurring…

To examine the experiences of victimization and bullying among gifted students and their general education peers, we applied a latent transition analysis with longitudinal data from 299 gifted and 689 general education students (fifth to ninth graders). We identified 4 latent statuses for victimization (4.8%-5.2%, frequent victims; 7.4%-12.2%,…

The authors of this article analyzed data from the National Longitudinal Transition Study-2 to determine the effect of receiving transition planning education and having a transition plan that specified needed postsecondary accommodations on the receipt of disability-specific services and generally available supports at the postsecondary level by…

Secondary data analysis using the National Longitudinal Transition Study-2 data set was conducted to examine the degree to which autonomy, psychological empowerment, and self-realization (3 of 4 essential characteristics of self-determination) play a mediating role in the relationship between school-based factors and postschool outcomes. The…
