The Control Preferences Scale (CPS) was developed to measure a construct that emerged from a grounded theory of how treatment decisions are made among people with life-threatening illnesses. The control preferences construct is defined as "the degree of control an individual wants to assume when decisions are being made about medical treatment." The CPS consists of five cards that each portrays a different role in treatment decision-making using a statement and a cartoon. These roles range from the individual making the treatment decisions, through the individual making the decisions jointly with the physician, to the physician making the decisions. The CPS involves subjects in making a series of paired comparisons to provide their total preference order over the five cards. These preference orders are analyzed using unfolding theory to determine the distribution of preferences in different populations and the effect of covariates on consumer preferences. The scale has been tested in a variety of populations, ranging from the general public to highly stressed groups. The CPS has proven to be a clinically relevant, easily administered, valid, and reliable measure of preferred roles in health-care decision-making.
控制偏好量表（CPS）的开发旨在衡量一种源自扎根理论的结构，该理论阐述了危及生命疾病患者如何做出治疗决策。控制偏好结构被定义为“在做出医疗治疗决策时，个体希望承担的控制程度”。CPS由五张卡片组成，每张卡片通过一句话和一幅卡通画描绘了治疗决策中不同的角色。这些角色从做出治疗决策的个体，到与医生共同做出决策的个体，再到医生做出决策。CPS让受试者进行一系列成对比较，以提供他们对五张卡片的总体偏好顺序。使用展开理论分析这些偏好顺序，以确定不同人群中偏好的分布以及协变量对消费者偏好的影响。该量表已在从普通公众到高压力群体等各种人群中进行了测试。事实证明，CPS是一种在医疗保健决策中对偏好角色具有临床相关性、易于实施、有效且可靠的测量工具。
