Why this discipline needs its own guide
Background
Public-health research operates at population scale and typically involves multi-sector partnerships: ministries of health, local authorities, community organisations, advocacy groups, and the academic team that anchors the methodology. CRediT captures the academic contribution well but is less well suited to the stakeholder-engagement contributions that determine whether a public-health intervention works in the field.
The Lancet Public Health, BMJ Global Health, and the American Journal of Public Health all expect CRediT statements. For complex interventions, supplement the statement with an Acknowledgements paragraph naming community partners, lived-experience contributors and implementation-site staff with their specific contribution.
Key considerations
How to assign the roles
- Community-based participatory research partners frequently meet the Conceptualization bar but are not always granted authorship. Where the journal’s policy allows, name them as authors with the CRediT roles they performed.
- Implementation-science contributions to programme adaptation belong under Methodology and Investigation.
- Health-economic evaluations done alongside the primary analysis are Formal Analysis, with the health economist named as a co-author.
- Policy translation, advocacy work and media engagement do not fit the current CRediT vocabulary; record them in the Acknowledgements with the named contributor and contribution.
- For pandemic-response and rapid-evidence papers, distinguish Investigation from Project Administration carefully — the lines blur under time pressure but the roles remain distinct.
Reporting Guideline Integration
TIDieR to CRediT Crosswalk
Mapping Template for Intervention Description & Replication to CRediT Roles
Public health relies heavily on complex population interventions. The TIDieR checklist ensures clear reporting of how interventions are designed and delivered. This crosswalk aligns TIDieR items with CRediT roles to ensure accurate operational attribution.
| Checklist Item / Phase | Mapped CRediT Role(s) | Guidance & Practical Allocation |
|---|---|---|
| 1. RationaleWhy the complex intervention was designed and how it functions. | ConceptualizationMethodology | Defining theoretical framework of behavioral change is Conceptualization. Defining programmatic mechanics maps to Methodology. |
| 2. MaterialsDeveloping training booklets, community pamphlets, and digital platforms. | ResourcesMethodology | Creating intervention guides or protocols is Methodology. Formatting, printing, or purchasing training items maps to Resources. |
| 3. ProceduresRunning training sessions, public health campaigns, and health workshops. | InvestigationProject Administration | Running focus groups or conducting public education sessions is Investigation. Organizing schedules and tracking compliance is Project Administration. |
| 4. Intervention ProvidersSelecting and training community workers, educators, and clinicians. | InvestigationSupervision | Performing actual patient training is Investigation. Overseeing and evaluating clinical training of providers maps to Supervision. |
| 5. Mode of DeliveryIn-person vs. digital health systems, text alerts, or community events. | MethodologyInvestigation | Deciding the intervention platform belongs to Methodology. Running the actual deliveries or clinic pipelines is Investigation. |
| 6. Location & SettingSecuring clinic sites, schools, or city districts. | Project AdministrationResources | Managing regional site coordinates is Project Administration. Funding or renting facilities maps to Resources. |
| 7. Intervention TailoringAdapting health materials to local cultures, languages, or settings. | MethodologyInvestigation | Creating protocol adaptation structures is Methodology. Field testing adaptations with community leaders maps to Investigation. |
| 8. Fidelity & AdherenceMeasuring how closely the public health intervention matches plans. | ValidationSupervision | Systematic testing of site deliveries is Validation. Direct clinical monitoring of worker compliance maps to Supervision. |

Common questions
Frequently asked
How do I assign CRediT roles for community partners and stakeholder engagement in public health?
CRediT captures the academic contribution well but does not have vocabulary for stakeholder engagement. Where community-based participatory research partners meet the Conceptualization bar and the journal's policy allows, name them as authors with the roles they performed. Policy translation, advocacy, and media engagement do not fit the current CRediT roles — record them in an Acknowledgements paragraph naming the contributor and the specific contribution.
Does CRediT cover everything a public-health intervention involves?
No — CRediT does not yet cover the stakeholder-engagement contributions that often determine whether a population-level intervention works in the field. For complex interventions, supplement the CRediT statement with an Acknowledgements paragraph naming community partners, lived-experience contributors, and implementation-site staff and their specific contributions.
