Choice experiments for complex choices: the case of contraceptives
Key objective:
To use choice experiments to investigate the interaction of women’s and general practitioners’ preferences with regard to contraceptive choices
The range and complexity of contraceptive choices introduced over the past 5 years pose a significant challenge for GPs to provide information and recommendations to women, in the limited consultation time available. No detailed data are available about the factors which will influence a woman’s choice of method or the way GPs will deal with these issues.
This research will quantify the trade-offs that women make in assessing different contraceptive alternatives, provides information about how they will choose under different circumstances, and seeks to predict uptake of new products. These data are necessary to inform GPs in providing appropriate advice and recommendations to women.
The data collection has been completed for this study:
728 women participated in 2 choice experiments.
162 GPs completed 2 choice experiments.
Results have been presented at the Australasian Health Economics Society conference in Hobart in 2009 , the Health Services Research conference in Brisbane in 2009 and the iHEA 8th World Congress, Toronto, Canada in 2011

The scope of the project was extended in 2010 with support from a UTS Faculty of Business Research Grant. The Faculty funding resulted in the development of code for estimating the Generalized Multinomial Logit model in Stata© software in collaboration with Dr Arne Hole from Sheffield University, UK.
