OPR systematic mixed studies review: 11-step coding process |
|---|
1. Research team members asked to reach consensus on a codebook |
2. Coders trained using a purposeful sample of documents (studies) |
3. Codebook pilot tested using a random sample of 10% of documents |
4. Codebook revised accordingly |
5. Coding of all documents by two independent coders (assignment of excerpts of QUAL findings and QUAN results to codes using the codebook) |
6. Disagreements between coders resolved by a third party |
7. For each code, inter-coder agreement and reliability (kappa) score calculated |
8. Preliminary findings discussed with research team members |
9. Emerging categories discussed and creation of new codes when needed |
10. All documents re-coded (steps 5 to 9) using new codes to increase consistency |
11. Statistical analysis |
