SECTION 10: METHODOLOGY NOTES

Research Selection Criteria

All research cited in this bibliography meets the following criteria:

1. Peer-Reviewed: Published in academic journals with peer review process

2. Recent: Published within last 20 years (with exceptions for seminal works)

3. Rigorous Methods: Uses randomized controlled trials, quasi-experimental designs, or robust observational methods

4. Replicable: Results confirmed across multiple jurisdictions or studies
