Cross-cultural validation and formulation of key evidence-based back pain messages for Zambian nurses.

The 14 messages on back pain given to the participants were reviewed to enhance clarity, applicability, and acceptability. Messages with similar meanings were merged, reducing the total number to 7. The revisions made to the 14 back pain messages aimed to improve understanding, acceptability, and relevance within the contexts and circumstances in which nurses' practice. This is important because the messages adapted for use in low- and middle-income countries like Zambia are equivalent and applicable to those originally developed in high-income countries.
