At present, HPR in the context of shared decision making rarely addresses the extent to which patients and other parties involved want to participate in decision making.

When role preferences are elicited in conjunction with health preferences, this can offer insight into the relevance of these health preferences to shared decision making, the extent to which health preferences are associated with role preferences and improve predictions of uptake based on health preferences.

Role preferences should be considered in formative research, inform the design of the preference instrument and the preference task, and be considered during statistical analysis, to better interpret the relevance of health preferences for medical and shared decision making.
