Qualitative Assessment of Face Validity and Cross-Cultural Acceptability of the Faces Pain Scale: "Revised" in Cameroon.

The Faces Pain Scale-Revised (FPS-R) is a self-report pain scale validated in numerous countries, but not in Cameroon. We postulated that while cultural factors influence pain perception and expression, the FPS-R should remain culturally acceptable for pediatric use. A convenience sample of 36 pediatric patients, aged 4 to 16 years, representing three primary language groups, was enrolled at Mbingo Baptist Hospital (MBH). Pre- and postanalgesia FPS-R scores and vital signs were obtained. Audio-recorded cognitive interviews were performed with each participant. Written questionnaires were also provided to physicians, nurses, and caretakers to further explore cultural perceptions of pain. Four independent reviewers analyzed interview transcripts and questionnaires using inductive reasoning and identified common themes pertaining to gender differences, societal roles, and pain perception. Basic comprehension of the FPS-R was present across language groups, vital sign changes corresponded with FPS-R alterations, and the FPS-R appears intuitive for pediatric use.
