[Acceptability of interventional materials: public participation in public health interventional research].

Introduction: The uptake rate of colorectal cancer screening remains insufficient in France and decreases as the level of deprivation increases. Participants’ health literacy appears to be an important determinant of screening uptake.

Aim Of The Study: The aim of this study, nested in our multicenter-randomized controlled trial, was to present the development and acceptability of interventional material (training and a pictorial brochure) for general practitioners and healthcare users in disadvantaged geographical areas using a participatory involvement approach.
