The goal of this trial is to identify the most effective ways for schools to deliver RAP Club, a universal school-based mental health intervention. RAP Club is an evidence-based group program designed to help 8th grade students manage stress, regulate emotions, and make healthy decisions. This study investigates two factors related to program implementation: type of program facilitator (teacher vs. school-based clinician) and level of facilitator supervision (standard vs. enhanced). The investigators will test four conditions that represent all combinations of these two factors. The main questions this study aims to answer are:
* Which combination of facilitator type and supervision level is most effective for improving student mental health?
* How much does each of the four conditions cost, and how cost-effective, practical, and acceptable is each?
The investigators will work with 32 public schools. Each school will deliver two RAP Club groups with approximately 15 students per group. One group will be led by a school clinician and the other by a teacher. One of these facilitators will be randomized to receive weekly group supervision and the other to receive enhanced supervision, which also includes observation and coaching. The investigators will collect survey data on student mental health at baseline, after RAP Club, at 4-month follow-up, and at 12-month follow up when students are in 9th grade. The investigators will also collect academic data, program delivery data (e.g., attendance), and feedback from students, facilitators, and principals.
