Enhancing Orthographic Communication and Literacy Outcomes for AAC Learners

The goal of this clinical trial is to determine whether adding Integrated Decoding and Encoding instruction to the ALLSTAR literacy program improves reading outcomes for students with significant literacy and communication needs. The study will also examine how students' reading skills change over time across instructional conditions. The main questions it aims to answer are: Do students who receive ALLSTAR with Integrated Decoding and Encoding instruction demonstrate greater improvements in literacy outcomes than students who receive ALLSTAR as standard care alone? How do students' literacy skills change from baseline to mid-intervention and post-intervention across the two instructional conditions? Researchers will compare two groups using a randomized controlled trial design. One group will receive 60 lessons of ALLSTAR as the standard of care (ALLSTAR-SC), and the other group will receive 60 lessons of ALLSTAR with the addition of Integrated Decoding and Encoding lessons (ALLSTAR-I\*). Literacy outcomes will be measured using repeated assessment probes at baseline (0 Lessons), after 30-40 lessons, and after 60 lessons to evaluate differences between groups and changes over time in the individuals.

Harnessing Communication Preferences

The goal of this clinical trial is to evaluate how preference for communication approach (e.g., using a touch talker versus picture cards) impacts treatment maintenance in the context of treatment to reduce challenging behavior exhibited by individuals with intellectual and/or developmental disabilities. As well, the clinical trial will evaluate how this preference impacts treatment relapse when care providers implement intervention and will identify potential demographic variables (e.g., age and symptom severity) that affect outcomes. The main question\[s\] it aims to answer \[is/are\]: Preferred communication strategies will persist to a greater extent when intervention is disrupted, relative to less preferred communication strategies. Communication modality preference will increase persistence for individuals with lower pre-experimental symptom severity scores and higher pre-experimental communication functioning scores. We predict demographic characteristics and developmental level will not impact intervention outcomes. Two groups will be compared. Group 1 will receive initial intervention using a preferred communication strategy. Group 2 will receive initial intervention using a non preferred, but effective, communication strategy. Intervention type will then be reversed. Researchers will compare preferred and non preferred interventions on continued expression of the communication strategy when intervention is challenged. Participants will exhibit alternative appropriate communicative behavior as a means of replacing/reducing challenging behavior. This will take place using (a) preferred communication strategies and (b) non preferred communication strategies. Following successful intervention with each type of communication, intervention will be challenged and continued use of the communication strategy will be measured.

Heart Rate Informed Changes in Care for Non-Communicating Patients

The overarching aim is to generate knowledge to reduce incidence of pain in non-verbal patients' everyday life. The trial will 1) evaluate how HR can be used to identify potentially painful care procedures that should be re-evaluated in terms of the approach taken; 2) test the effect of heart rate (HR)-informed changes in potentially painful care procedures on biomarkers of pain, and 3) assess how six weeks of communication through HR affects the quality of communication between patient and caregiver.
