The impact of language on the expression and assessment of pain in children.

This paper focuses on the importance of language in the expression of pain. Variation in definitions of pain is presented, together with a review of the evidence examining the impact language may have on the way pain is expressed linguistically. The implications for conducting research with children who speak different languages are explored. Strategies such as using non-linguistic methods of communication, additional time required for conducting interviews and the inclusion of research team members from the same ethnic or linguistic background are presented.
