To ascertain whether a physician who uses a computer-assisted diagnostic support system (DSS) would be rated less capable than a physician who does not.
Students assumed the role of a patient with a possible ankle fracture (experiment 1) or a possible deep vein thrombosis (experiment 2). They read a scenario that described an interaction with a physician who used no DSS, one who used an unspecified DSS, or one who used a DSS developed at a prestigious medical center. Participants were then asked to rate the interaction on 5 criteria, the most important of which was the diagnostic ability of the physician. In experiment 3, 74 patients in the waiting room of a clinic were randomly assigned to the same 3 types of groups as used in experiment 1. In experiment 4, 131 3rd- and 4th-year medical students read a scenario of a physician-patient interaction and were randomly assigned to 1 of 4 groups: the physician used no DSS, heeded the recommendation of a DSS, defied a recommendation of a DSS by treating in a less aggressive manner, or defied a recommendation of a DSS by treating in a more aggressive manner .
The participants always deemed the physician who used no decision aid to have the highest diagnostic ability.
Patients may surmise that a physician who uses a DSS is not as capable as a physician who makes the diagnosis with no assistance from a DSS.
确定使用计算机辅助诊断支持系统（DSS）的医生是否会被认为比不使用该系统的医生能力更低。
在实验1中，学生扮演可能脚踝骨折的患者；在实验2中，学生扮演可能患有深静脉血栓的患者。他们阅读一段描述与不使用DSS的医生、使用未指明的DSS的医生或使用在著名医学中心开发的DSS的医生之间互动的情景。然后，参与者被要求根据5项标准对这种互动进行评分，其中最重要的是医生的诊断能力。在实验3中，诊所候诊室的74名患者被随机分配到与实验1相同的3种类型的组中。在实验4中，131名三、四年级医学生阅读一段医患互动情景，并被随机分配到4组中的1组：医生不使用DSS、听从DSS的建议、以不那么积极的方式治疗从而违背DSS的建议，或以更积极的方式治疗从而违背DSS的建议。
参与者始终认为不使用决策辅助工具的医生诊断能力最高。
患者可能推测，使用DSS的医生不如在没有DSS协助的情况下进行诊断的医生有能力。
