Assessing the Evidence Base for School-Based Promotion and Prevention Interventions: Introduction to the Series.

Schools are an important component in the mental health system of care for youths. Teachers and other school staff have unique opportunities to promote emotional wellness and prevent mental health conditions. Although numerous programs are available, identifying evidence-based and effective options is a significant challenge. This introduction lays out the rationale and methodology of the Assessing the Evidence Base (AEB) series, a collection of systematic reviews of school-based mental health promotion and prevention approaches recommended by the National Academies of Sciences, Engineering, and Medicine for students in kindergarten through grade 12. Authors of the current AEB series used the rating criteria derived from the 2014 AEB series, which provided systematic reviews of a wide spectrum of interventions for mental and substance use disorders. Like its predecessor, the current series upholds a high standard of scientific rigor while ensuring that the information is easily accessible to various stakeholders in education, behavioral health, and communities. It describes the universal features included in each systematic review, such as a rating of the level of evidence for interventions, intervention program components, identification of interventions that have yielded positive outcomes for students from underserved populations, and a review of cost data. The AEB systematic reviews will serve as an important tool for decision makers involved in managing limited resources for various programs in school-based mental health services by synthesizing large bodies of research for use by leaders in education and behavioral health.
