Hi,
For those who may be interested, we (at Universite de Montreal), have worked on a (unofficial, but still useful !) translation of the APA6th Style file.to match requirements of the french language. It can be downloaded here : http://www.bib.umontreal.ca/LGB/styles-bibliographiques.htm
The adaptation is partly based on the following book :
Provost, M. A., et al. (2006). Normes de présentation d’un travail de recherche (2e éd.). Trois-Rivières, Québec : Éditions SMG.
Once installed, specifications and exact nature of changes can be viewed in Endnote by clicking Edit > Output Styles > Open Style Manager… , than choosing APA6th-fr-udem and Edit.
Regards,
Dominic
