Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* What is the optimal training timing, duration, and frequency for lay rescuers that leads to CPR skill retention?
* What is the impact of CPR manikin type (high-fidelity, inflatable, nontraditional objects) on skill retention?
* How do specific features of training modality -- such as contextualization, gamification, and emotional engagement -- impact skill proficiency, knowledge retention, and attitudes about CPR?
Participants will
* Answer pre-training questionnaires
* Participate in CPR training
* Participate in CPR skills testing
* Answer post-training questionnaires
Researchers will compare different methods of training, different frequencies of training, and different manikin types.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study addresses these critical gaps by comparing various CPR training methods and procedures. The project tests the effectiveness of different training frequencies, durations, and delivery modes-including traditional instructor-led sessions, brief refreshers, and a novel, emotionally immersive serious game. The serious game leverages gamification, competition, and scenario-based learning to build "emotional muscle memory" and prepare students for real-world emergencies.
Participants are enrolled from two high schools-one rural, one suburban-and randomized by class or individual into training arms with varied schedules and compression practice tools. These tools range from high-fidelity manikins to low-fidelity devices and improvised household objects. Outcomes include CPR performance metrics (compression rate, depth, recoil, and hand placement), knowledge retention, emotional engagement (measured via validated psychometric scales), and confidence in responding to cardiac arrest.
Training sessions are delivered during the academic year, and students are assessed immediately after training and again at annual follow-up points. Data are collected in a de-identified format using school-issued ID numbers, ensuring participant confidentiality. Analysis will use generalized estimating equations and mixed-effects models to assess the impact of training method and frequency on skill retention and psychosocial readiness. The study also explores the role of contextualization, emotional engagement, and gamification as mediators of improved CPR performance.
Ultimately, this multi-year trial aims to identify scalable, cost-effective strategies that optimize CPR training outcomes for lay rescuers. By improving technical skill retention and emotional preparedness, the study addresses key priorities for public health impact and aligns with NHLBI's strategic goals to reduce mortality from sudden cardiac arrest.

RANDOMIZED
PARALLEL
Aim 2: A 2-year, individually randomized trial at a suburban high school compares four chest compression practice tools: high-fidelity manikin, low-fidelity manikin, a novel "no-head" manikin, and improvised objects. Ninth-grade students (N\~432) are assessed post-training and at 1 year for CPR skill quality (rate, depth, recoil, hand placement) using objective measurement tools.

Control
No CPR training
No interventions assigned to this group
Standard High-fidelity Manikin
Uses a commercially available torso manikin with realistic chest mechanics and feedback. Serves as the gold standard comparator for CPR training.
CPR Manikin Type
Various types of CPR manikins are compared
Low-Fidelity Manikin
Uses a basic inflatable torso manikin with minimal feedback or resistance. Represents a low-cost, commonly used alternative in schools and communities.
CPR Manikin Type
Various types of CPR manikins are compared
No-Head Manikin (Prototype)
Uses a custom-built spring-based device with a silicone topper and realistic force-displacement properties that closely mimic the human chest. Tests whether an affordable, biomechanically accurate prototype can improve compression quality.
CPR Manikin Type
Various types of CPR manikins are compared
Non-Traditional Object
Uses improvised materials (e.g., toilet paper rolls) to simulate chest compressions. Evaluates the feasibility and effectiveness of ultra-low-cost CPR practice tools
