In French-speaking minority communities, the need to actively offer services in French (rather than when the request to do so is made) is increasingly recognized. Hence, there is a need to educate health and social care providers regarding this approach and to evaluate the results. This article describes the process used (literature review, consultation with experts, cross-Canada Delphi study) to create and validate the content of two questionnaires assessing the presence of indicators of active offer of health and social services in French: one assessing individual behaviours of active offer among care providers, and another assessing their perception of the organizational support they receive to actively offer services in French.
