Often, clinical decision making of reconstructive procedure is coupled and their concurrent resolution by interacting stakeholders is required. This study was to give new insight into the tradeoff method to elicit the utility function first and then the probability weighting function, to determine if and how stakeholder engagement can contribute to managing decisional conflict processes. The proposed methodology is illustrated through three subjects (physician, patient and family member). We found that significant evidence of probability weighting both at the aggregate level and at the individual subject level. The pattern of probability weights is consistent with an inverse shaped probability weighting function: Small probabilities are overweighed and intermediate and large probabilities are underweight. In addition, the degree of upper subadditivity exceeds the degree of lower subadditivity. Finally, the proposed procedure can reduce clinical risk by considering stakeholders' behavior attribute and providing physicians the effective support need for quality decision making.
