目的通过分析修订后的“观察患者参与决策”量表（OPTION）在基层医疗咨询中的应用，探讨其心理测量学特性。OPTION工具评估到什么程度的临床医生参与患者的决策。设计横断面评估的医疗互动由两个校准raters。设置初级保健。参与者21个全科医生提供了186个咨询评估。测量观察评分使用OPTION工具。结果与第一版的OPTION量表相比，修订后的量表，使用一个大小，而不是一个态度量表，当应用于同一数据集，导致在规模的可靠性和较低的分数为从业者实现的参与程度的改善。因子分析证实，它是可以接受的，把量表作为一个单一的结构。虽然在逐项评估评分员时存在中等变异性，但评分员之间在OPTION总分水平上的一致性较高（OPTION总分的组内相关系数得分为0.77），这一水平可用于评价每位从业者的一组咨询（例如5和10个协商），其中总分数将用于确定整体performance.Conclusions我们的结论是，OPTION是足够可靠的，可用于正式评估在整个工具（所有12个项目）的水平。
Objective To examine the psychometric properties of a revised scale, named 'observing patient involvement in decision making' (OPTION), by analysing its reapplication to a sample of routine primary care consultations. The OPTION instrument assesses to what degree clinicians involve patients in decision making.Design Cross-sectional assessment of medical interaction by two calibrated raters.Setting Primary care.Participants Twenty-one general practitioners provided 186 consultations for assessment.Measurements Observational score using the OPTION instrument.Results Compared with the first version of the OPTION scale, the revised scale that uses a magnitude instead of an attitude scale, when applied to the same data set, resulted in improvement in the scale's reliability and to lower scores for the levels of involvement achieved by the practitioners. Factor analysis confirms that it is acceptable to regard the scale as a single construct. Although there is moderate variability when raters are assessed on an item by item basis, the agreements between raters at the level of the overall OPTION score is high (the intraclass correlation coefficient scores for total OPTION score was 0.77), a level that is acceptable for the evaluation of a set of consultations per practitioner (e.g. between 5 and 10 consultations), where aggregate scores would be used for determining overall performance.Conclusions We conclude that OPTION is sufficiently reliable to be used for formal assessment at the level of the whole instrument (all 12 items).
