Research · Methodology

Measuring the evidence gap, country by country.

A scoring framework for making a country's evidence gaps visible before fieldwork begins, designed to be re-applied by local collaborators.

The Framework · RCI

Five dimensions. Twenty-five points. One score per country.

The Research Coverage Index scores the existing evidence base for midlife women's health in any APAC country. Each dimension is scored 0–5 against published criteria and designed for peer review.

Dimension Vietnam · Phase 0 Score
01
Epidemiological coverage
Population-representative datasets, age-stratified incidence, prevalence of vasomotor and other midlife symptoms across the full national population.
VN: One published cohort, <2% of population. Kinh-urban skew.
1.5/5
02
Methodological rigour
Sampling strategy, validated instruments, longitudinal follow-up, replicability of published studies in the country.
VN: Convenience sampling dominant. No longitudinal follow-up published.
2.0/5
03
Ethnic & cultural representation
Are ethnic minorities, rural communities, and non-clinic-attending women represented in published cohorts at population-relative frequencies?
VN: 52 of 53 ethnic groups absent from the record. Rural cohorts: none.
0.5/5
04
Clinical guidelines
National menopause / MHT guidelines, currency of last revision, alignment with current international consensus, accessibility in local language.
VN: National guideline exists, last revised 2014. VI translation partial.
2.0/5
05
Translated instruments
Are validated symptom scales (e.g. MENQOL, Greene Climacteric Scale) translated, cross-culturally adapted, and re-validated for the country's population?
VN: MENQOL not VI-validated. Greene CS partial translation, unvalidated.
0.5/5
Total · Phase 0
Critically under-researched band (6–10). The first fieldwork cycle targets the largest gaps first: ethnic representation and translated instruments.
6.5/25
Vietnam · Phase 0 Result

What 6.5 / 25 means in practice.

Vietnam has 14M midlife women across 53 ethnic groups. Published cohorts cover <2% of that population, predominantly Kinh urban samples. Validated symptom instruments are not translated. National MHT guidelines were last revised in 2014.

Phase 0 · Complete
Desk research
2025 — 2026

Systematic literature review, RCI scoring, country brief drafting, and clinical background consultation with Vietnam contacts.

Phase 1 · Now
Pilot fieldwork
2026 — 2027

Mixed-methods fieldwork pathway. Candidate minority and Kinh-majority contexts under review, with consented photography and oral histories alongside the research protocol.

Field · Communities

Communities, not clinics.

DFV Phase 1 recruits women in their working environments — fields, markets, homes — not in tertiary care waiting rooms. Translators are trained on consent architecture, not script delivery.

Photographs accompany every cohort visit, with consent reaffirmed at each frame. Subjects review prints before any image enters the research record.

Publication Pipeline

Open-science by default.

Preprints first. Peer-reviewed venues co-selected with country clinical collaborators. Co-authorship terms agreed in writing before fieldwork begins.

Commitments · Protocol

What we commit to before we publish.

Each commitment is recorded in the country MoU and reviewed by the advisory board on annual cadence.

01 · Consent

Recontact consent at every visit.

Participants re-consent at each interaction. Photography consent is separate from research consent and revocable at any time, including after publication.

02 · Translation

Translators trained, not transcribing.

Country clinical collaborators train local translators on instrument adaptation, cultural idiom, and clinical vocabulary — before any cohort visit. Translation notes are part of the dataset.

03 · Data governance

Sovereignty stays with country.

Primary data resides in-country with the coordinator's institution. DFV holds working copies under data-sharing agreement. Indigenous data sovereignty principles apply where relevant.

04 · Documentation consent

The whole process is consented.

Consent covers the full documentation workflow, including portraits and behind-the-scenes material where approved. Devices, operators, permitted uses, and withdrawal terms are documented before any image, audio, or video is captured.

Research Governance

Roles before names.

DFV separates methodology, country clinical input, ethics review, and public translation. Named collaborators appear publicly only after role scope and listing consent are clear.
