Abstract:
This study was an important start to explore the feasibility of applying stated
preference discrete choice modelling (SPDCM) for use in developing breast screening
participation enhancement strategies. It needs to be followed by further research to
establish model validity and authoritative results. In the meantime a random effects
binary probit choice model was estimated using a main effects with selected 2-way
interaction design and a convenience sample of Australian breast cancer screening
participants. A response rate of 48% was obtained. Clear preferences for different
service configurations were revealed and used to demonstrate how potential
strategies to enhance future participation rates of women placed on routine recall
could be identified. As anticipated accuracy of screening was the most important
attribute of the service to influence the probability of uptake but others were
screening time, travel time, information about screening benefits and the desire for
privacy lending support to the view that benefit assessment goes beyond health
factors. In summary, the SPDCM approach can be regarded as a judicious approach
for helping decision-makers improve screening participation.
