The aim of this article is to describe the modification of an instrument to secure cultural validity using cognitive interviewing to adequately examine and address health issues in a diverse population.
Method
Cultural experts (n = 8) on the Lakota reservation were identified to provide input on cultural items of an instrument. Two rounds of cognitive interviewing ensued with each expert. The instrument items (n = 40) were reviewed and revised as indicated.
Results
The results of this project were twofold; a culturally valid instrument was developed, and a process was delineated to ensure cultural validity. Content validity was supported by the 100% consensus among the Lakota cultural experts on every item.
Discussion
This article describes how cognitive interviewing was applied for instrument modification to obtain cultural validity resulting in a relevant instrument which may useful to researchers when working with diverse populations that have unique needs.
