school-based intervention
any strategy implemented in a classroom setting to improve the health and well-being of students, often by reducing or preventing pathology and problem behaviors (e.g., depression, social anxiety, cigarette smoking, drug or alcohol use, bullying and aggression). Requiring interdisciplinary coordination among school psychologists, counselors, social workers, teachers, and administrative staff, programs may be targeted at subgroups of high-risk individuals or implemented across the general school population of children and adolescents. Interventions may incorporate such activities as specially designed lectures, guided online lessons, group discussions, role play, and special homework assignments to be completed with parents.
