Mental health-enhanced Positive Behavioral Interventions and Supports (PBIS-MH) integrates mental health into the three core elements of PBIS. 1) School-based mental health clinicians are included on leadership teams. 2) Data from teacher and student perceived school climate, as well as universal screening for aggression and mental health difficulties, are used to inform intervention decision-making. 3) Evidence-based mental health prevention and intervention practices are layered into PBIS' three-tiered continuum.

PBIS-MH+RED involves the components of PBIS-MH integrated with racial/ethnic discrimination interventions (RED) to address multiple forms of school-based racial and ethnic discrimination. 1) Unintentional bias training for school personnel, involving teaching participants to conceptualize prejudice as well as strategies to reduce bias. 2) Unintentional bias training for students that is delivered in a classroom in a developmentally appropriate lesson format. 3) Vulnerable Decision Point process: Leadership teams are trained to reduce disparities in school discipline by a) using disaggregated student discipline data to identify particular settings or practices that are drivers for racial/ethnic disproportionality in a school and b) using iterative problem-solving to address these drivers. 4) Teacher stress reduction training where they are provided with strategies to reduce stress.
