Context: To enable women to make a well informed choice of the contraception method requires that their considerations are known. Some women do not know what the alternatives are and how they fit with their lifestyle and preferences. Doctors know what is available and can discuss with each woman what would be the best option for them. But the medical consultation situation does not always permit reaching the best fit between women preferences and feasible alternatives. Objective: To develop a self-fulfilled questionnaire recording personal history, lifestyle and preferences on contraception alternatives to help choosing the best contraceptive option for each woman and to save and optimize HCP’s time. Methods: After a literature review was done to gather potential aspects related to contraception choice, a questionnaire (version 0) was developed and a multi-national group of 8 experts in contraception reviewed it based on a 3 days’ on-line bulletin board discussion. Version 1 was tested through cognitive debrief interviews with 10 English native target women. A reviewed version 2 of the questionnaire was then evaluated by a group of 82 gynaecologists/obstetricians from across Europe in a face to face workshop session including an on line voting system. A new reviewed version 3 was then evaluated by an additional pan-European sample of GPs and gynaecologists/obstetricians following an on line questionnaire. Results: The final conceptually validated CHLOE questionnaire will be presented. It includes three sections: general and clinical characteristics, health conditions and preferences on contraceptive methods. Conclusions: CHLOE questionnaire has been developed to help the choice of contraception that best fits to each woman. Further steps are needed to linguistically and culturally adapt the questionnaire to be used across Europe.
