Virtual unenhanced images from a dual-energy CT multimaterial decomposition algorithm yield renal mass attenuation comparable to true unenhanced images for both enhancing renal masses and nonenhanc... Background Virtual unenhanced (VUE) images obtained by using a dual-energy CT (DECT) multimaterial decomposition algorithm hold promise for diagnostic use in the abdomen in lieu of true unenhanced ...

The implementation of schoolwide positive behavior interventions and supports (SWPBIS) requires a shift from a reliance on reactionary discipline to prevention-oriented supports, and it requires that staff adopt and regularly apply the practices throughout the building. This level of systemic change in staff thinking and practice is challenging to achieve and sustain, but data can assist teams in navigating the process. The Staff Perceptions of Behavior and Discipline (SPBD) is a needs assessment survey developed to measure staff beliefs, needs, and concerns for discipline and behavioral support practices. This tool can help teams make data-informed decisions, and target professional development to fit the needs and concerns of staff in their building. This study reexamines the internal consistency and factor structure of the SPBD using an expanded data set of 147 schools, including elementary, middle, and high schools across several geographic regions in the United States. The results corroborate the SPBD’s existing factor structure over alternative factor structures and support the internal consistency of each subscale. Implications for practice and future research are provided.

Student voice is essential for PBIS, but a tool for gathering students’ perspectives of PBIS is not available in the literature. The purpose of this study was to develop and validate a universal–level PBIS survey for students, the Student Perceptions of Behavior and Discipline (StPBD). This survey was designed to mobilize student engagement and guide implementation with cultural and contextual fit. Survey development was informed by literature review, feedback from users and researchers, pilot tests, and exploratory and confirmatory factor analysis. Analyses of items designed to measure aspects of school climate, student–staff relationships, and family connections confirmed these three distinct factors. Linear mixed–effect analyses revealed significant relationships between the survey, student perceptions of PBIS practices in the school, school level, discipline, and gender identity.
