This article reports the results of a follow-up analysis of 779 students with disabilities who participated in group-randomized, control group studies designed to examine the efficacy of self-determination interventions in secondary school to examine the relationship between self-determination status when exiting high school and adult outcomes 1 and 2 years post-high school. Findings suggest that self-determination status upon exiting high school predicts positive outcomes in the domains of achieving employment and community access 1 year post-school, and that exposure to self-determination interventions in secondary school may lead to more stability in student outcomes over time. The complexity of the relationship between self-determination intervention and outcomes is discussed, as are recommendations for future research and practice.

Nonacademic skills related to college and career readiness (CCR) have become more prevalent in the literature as proposed conceptual models and frameworks, yet little empirical research exists in their support. We employed latent variable modeling to empirically test a previously proposed six-domain framework of CCR for adolescents with and without disabilities. Results support four specific factors of CCR: Academic Engagement, Critical Learning Processes, Mind-Set, and Transition Knowledge. Using a bifactor model, we confirmed one general factor (CCR) and one specific factor (Transition Knowledge), established measurement invariance on the basis of disability, and found latent mean differences between these groups; students without disabilities had greater overall CCR and transition knowledge. Findings support the use of a CCR measurement model with two potential factor scores in future research and practice and may inform efforts to measure CCR nonacademic skills.

There has been an increased focus on the tenets of implementation science in special education research, namely on the degree to which interventions are implemented as intended (i.e., fidelity of implementation) and factors that influence fidelity of implementation. For complex interventions, such as the Self-Determined Learning Model of Instruction (SDLMI), there is an ongoing need to refine conceptualizations of fidelity of implementation and the factors that influence it in inclusive educational contexts. Therefore, the purpose of this paper is two-fold: (1) to describe a framework for conceptualizing fidelity of implementation factors that influence fidelity when evaluating a complex intervention like the SDLMI and (2) to present initial content validity and internal consistency of a new measure designed to assess specific aspects of fidelity of implementation of the SDLMI in inclusive, general education classrooms. Implications and future directions for research in implementation science, special education, and self-determination interventions are described.

This study compared five common multilevel software packages via Monte Carlo simulation: HLM 7, M plus 7.4, R (lme4 V1.1-12), Stata 14.1, and SAS 9.4 to determine how the programs differ in estimation accuracy and speed, as well as convergence, when modeling multiple randomly varying slopes of different magnitudes. Simulated data included population variance estimates, which were zero or near zero for two of the five random slopes. Generally, when yielding admissible solutions, all five software packages produced comparable and reasonably unbiased parameter estimates. However, noticeable differences among the five packages arose in terms of speed, convergence rates, and the production of standard errors for random effects, especially when the variances of these effects were zero in the population. The results of this study suggest that applied researchers should carefully consider which random effects they wish to include in their models. In addition, nonconvergence rates vary across packages, and models that fail to converge in one package may converge in another.

A major instructional focus of interventions designed to promote self-determination, such as the Self-Determined Learning Model of Instruction (SDLMI), is to engage students in learning to set their goals, identify action plans, and evaluate their performances. However, little is known about how students define their goal attainment outcomes, or the degree to which students and teachers agree the attainment of goal set using the SDLMI in inclusive general education classes. This study examined the relation between student and teacher ratings of goal attainment during the first semester of a longitudinal, cluster randomized controlled trial of the SDLMI, as well as the impact of student disability status and teacher supports for implementing the SDLMI (i.e., online resources vs. online resources + in-person coaching) on goal attainment. Findings suggested the feasibility of engaging students with and without disabilities in rating their goal attainment process during SDLMI in secondary schools, with kappa analysis indicating that, when credit is given for at least partial agreement between students and teachers, there is a fair amount of interrater agreement using conventional interpretation criteria. Importantly, however, conclusions drawn about the impact of student (i.e., disability status) and teacher factors (i.e., teacher implementation supports) on goal attainment outcomes are impacted by whether student or teaching ratings of goal attainment are utilized as the outcome measure. Implications for future research and practice are described.
