Abstract: Burden of disease (BOD) estimates used to foster local health policy require disability weights which represent local preferences for different health states. The global burden of disease (GBD) study presumes that disability weights are universal and equal across countries and cultures, but this is questionable. This indicates the need to measure local disability weights across nations and/or cultures. We developed a culturally adapted version of the visual analogue scale (VAS) for a setting in rural Burkina Faso. Using an anthropologic approach, BOD‐relevant health states were translated into culturally meaningful disability scenarios. The scaling procedure was adapted using a locally relevant scale. Nine hypothetical health states were evaluated by seven panels of in total 39 lay individuals and 17 health professionals. Results show that health professionals' rankings and valuations of health states matched those of lay people to a certain extent. In comparison to that of the lay people, health professionals rated seven out of nine health states as slightly to moderately less severe. The instrument scored well on inter‐panel and test–retest reliability and construct validity. Our research shows the feasibility of eliciting disability weights in a rural African setting using a culturally adapted VAS. Moreover, the results of the present study suggest that it might be possible to use health professionals' preferences on disability weights as a proxy for lay people's preferences.
