In the U.S. students in public schools with disabilities are protected via special education services under the Individuals with Disabilities Education Act (Individuals with Disabilities Education Act, 2004). As part of these regulations, schools are required to provide students aged 16 years and older with transition services to prepare them for life as adults. Research shows that there are links between participation, social engagement, work and well-being (Cacioppo, et al., 2014; Gilson, et al., 2022; Holt-Lunstad, 2018; Macdonald, et al., 2018) as well as a link between social isolation and increased mortality and morbidity (Snyder-Mackler, et al., 2020; Yang, et al., 2016), and yet parents of individuals with moderate to severe/profound, complex, or low-incidence disabilities do not always have transition experiences they feel set their child up for success in real-life situations (Lee & Kim, 2021; Snell-Rood, et al., 2020). This research study used a mixed methods structure to obtain research regarding parent perspectives on specific areas schools need to address to create strong and meaningful transition plans for their students who have more involved disabilities and may require more support. A literature review, a web-based parent survey, 6 one-to-one interviews, and a focus group of 4 interview participants were conducted to drive development of an online, self-paced instructional course comprised of five modules designed to be implemented with school administrators and IEP team members (including, but not limited to teachers, related service providers, psychologists, support staff, parents and students) highlighting immediately implementable strategies to strengthen the IEP transition process in which they participate. Results compiled from all sources support five main areas or themes for creating meaningful transition: collaboration/team/relationships, community based/real-life instruction, presumed competence/mindset, knowledge, and skills (of the parent and school team members), and individualizing the IEP. Additional research supports the use of specific team members (e.g. vocational rehab transition specialist (Plotner & Dyamond, 2017)) and a case is made for ensuring transition teams for students with moderate to severe/profound, complex or low-incidence disabilities include occupational therapists who are trained in the value of using meaningful participation to improve quality of life for their clients (AOTA, 2020). / Temple University.

Thesis advisor: Henry Braun / This study evaluates the accuracy, precision, and stability of three different methods of cross-survey analysis in order to determine their suitability for estimating the proportions of low-incidence populations. Population parameters of size and demographic distribution are necessary for planning and policy development. The estimation of these parameters for low-incidence populations poses a number of methodological challenges. Cross-survey analysis methodologies offer an alternative to generate useful, low-incidence population estimates not readily available in today's census without conducting targeted, costly surveys to estimate group size directly. The cross-survey methods evaluated in the study are meta-analysis of complex surveys (MACS), pooled design-based cross-survey (PDCS), and Bayesian multilevel regression with post-stratification (BMRP). The accuracy and precision of these methods were assessed by comparing the estimates of the proportion of the adult Jewish population in Canada generated by each method with benchmark estimates. The stability of the estimates, in turn, was determined by cross-validating estimates obtained with data from two random stratified subsamples drawn from a large pool of US surveys. The findings of the study indicate that, under the right conditions, cross-survey methods have the potential to produce very accurate and precise estimates of low-incidence populations. The study did find that the level of accuracy and precision of these estimates varied depending on the cross-survey method used and on the conditions under which the estimates were produced. The estimates obtained with PDCS and BMRP methodologies were more accurate than the ones generated by the MACS approach. The BMRP approach generated the most accurate estimates. The pooled design-based cross-survey method generated relatively accurate estimates across all the scenarios included in the study. The precision of the estimates was found to be related to the number of surveys considered in the analyses. Overall, the findings clearly show that cross-survey analysis methods provide a useful alternative for estimation of low-incidence populations. More research is needed to fully understand the factors that affect the accuracy and precision of estimates generated by these cross-survey methods. / Thesis (PhD) — Boston College, 2016. / Submitted to: Boston College.

Abstract Interrupted behavior chain procedures have been shown to be an effective way to teach individuals with intellectual disabilities and autism to mand for missing objects and information concerning missing objects. Research has shown that an interrupted behavior chain procedure is more effective than traditional mand teach trials, which occur at the onset of a behavior chain or in a massed trial format. However, there is a lack of research evaluating the use of interrupted behavior chain procedures to teach vocal mands for missing items and the possible generalization effects thereof. This study evaluated the acquisition of vocal mands for missing items using interrupted behavior chain procedures, as well as participants' generalization of learned mands to novel behavior chains when said chains were interrupted. Each participant exhibited some form of generalization to a novel chain suggesting that interrupted behavior chains may be an efficient means to teach mands to children with autism. However, the extent to which a mand generalized across topographically distinct chains was different for each participant, suggesting that an individual's verbal repertoire could be a factor influencing generalization.

This exploratory study assessed the effectiveness of a cross-age tutoring intervention on adaptive behavior goals of three PreKindergarten/Kindergarten-aged students with labels of autism spectrum disorder. Data were collected in an inclusive environment; the school library. Three fourth grade general education cross-age tutors were trained to use a simple, naturalistic least-to-most prompting strategy to support the young students with individualized adaptive behavior goals while in the library. A mixed method design was utilized in this study; a quantitative single case multiple baseline across participants design to show performance outcomes of the young students as a result of the tutoring intervention, and a constant comparison analysis of qualitative data gathered from observations of students, students' written work, and a research journal. Quantitative results indicated all three young students performed the target behavior in the library with support from their cross-age tutors and this behavior maintained one month after intervention ended as evident through a maintenance probe; all three students made progress on the achievement of adaptive behavior goals in an inclusive environment from this intervention. Qualitative results indicated the cross-age tutoring experience was positive and powerful for all six participants involved as evident through the construction of six themes that emerged from the qualitative data.

Instruction in academic core content provides students with moderate to severe disabilities a full educational opportunity that promotes current and future options in the community and can complement acquisition of daily living skills. However, high school teachers face many challenges in balancing instructional priorities given the mission to ensure all students are college and career ready. This article describes methods for designing instruction that is relevant, meaningful, and addresses multiple priorities during academic core content instruction for high school students with moderate to severe disabilities.

The What Works Clearinghouse guidelines for high-quality professional development were used to develop a Tell, Show, Try, and Apply (TSTA) method of training. This method was used to train teachers to align instruction to grade-level content for students with severe developmental disabilities. A total of 193 teachers of students who participate in alternate assessment based on alternate achievement standards from three states participated in the first 2 days of training. A subset of 37 teachers participated in a 3rd day of training and submitted products from classroom applications. The impact of the TSTA training was evaluated to determine its effect on teachers instructional fidelity across three content areas (e.g., English language arts [ELA], mathematics, science) with their own students. In addition, generalization to new academic content aligned to grade-aligned standards developed by the teachers was taken. Results indicated that the professional development was effective not only in increasing teachers knowledge of alignment but also grade-aligned instruction with generalization across content. Future research questions and practical application also are discussed.
