Our aim was to develop a measurement which enables research into the interdependent nature of clinical encounters. The prime objective was to develop an instrument capable of assessing the extent to which patients have been involved in (shared) decision making from two viewpoints-that of the patient and the clinician.
To develop an initial 'dyadic OPTION' instrument, the twelve original third-person items were drafted in passive, first person plural forms. Using this version initially, three rounds of cognitive debriefing interviews were held. These were audio-recorded and analysed at the end of each round and the results used to revise the dyadic OPTION scale.
It was possible to modify the observer OPTION instrument into an instrument for completion by both clinicians and patients after a dyadic interaction. Cognitive debriefing revealed five areas of interpretative difficulty. Each item of the observer OPTION scale underwent modification in order to develop a dyadic version of the scale.
The dyadic OPTION scale is acceptable and comprehensible by both clinicians and public respondents. Cognitive debriefing adapted and refined an existing scale and provided confidence that the core constructs of the scale (perceived involvement in decisions making) were understood.
Further validation of the dyadic OPTION scale is required prior to its use in research settings.
我们旨在开发一种测量工具，以研究临床互动的相互依存性质。主要目的是开发一种能够从患者和临床医生两个角度评估患者参与（共同）决策程度的工具。
为了开发初始的“对偶选项”工具，最初将十二项原始的第三人称项目起草为被动的第一人称复数形式。使用此版本，进行了三轮认知访谈。在每轮结束时对这些访谈进行录音和分析，并使用结果修改对偶选项量表。
在对偶互动后，有可能将观察者选项工具修改为供临床医生和患者共同完成的工具。认知访谈揭示了五个解释困难的领域。观察者选项量表的每个项目都经过修改，以开发出该量表的对偶版本。
对偶选项量表可被临床医生和公众受访者接受和理解。认知访谈改编和完善了现有的量表，并确信量表的核心结构（对决策的感知参与）得到了理解。
在对偶选项量表用于研究环境之前，需要对其进行进一步验证。
