目的：制定了决策准备（PrepDM）量表，以评估与患者决策准备和与医生对话相关的决策过程。本研究的目的是评估量表的心理测量properties.Methods：从2005年7月至2006年3月，在常规临床护理过程中，患者完成了一份问卷调查，包括：人口统计学信息，治疗意图，决策冲突，决策援助的可接受性，和PrepDM scale.Results：四百骨科患者完成了问卷。PrepDM量表显示与知情（r =-0.21，p < 0.01）和支持（r =-0.13，p = 0.01）子量表（DCS）显著相关;并在发现决策辅助和未发现决策辅助的患者之间进行了显著区分（p < 0.0001）。内部一致性的α系数范围为0.92至0.96。该规模是强烈的一维（主成分分析）和项目反应理论分析表明，所有10个规模项目的功能very well.Conclusion：PrepDM规模的心理测量特性是非常好的。实践的影响：规模可以让更全面的评估干预措施，旨在为患者准备的共享决策遇到复杂的医疗保健决策。(C)2009爱思唯尔爱尔兰有限公司保留所有权利。
Objective: The Preparation for Decision Making (PrepDM) scale was developed to evaluate decision processes relating to the preparation of patients for decision making and dialoguing with their practitioners. The objective of this study was to evaluate the scale's psychometric properties.Methods: From July 2005 to March 2006, after viewing a decision aid prescribed during routine clinical care, patients completed a questionnaire including: demographic information, treatment intention, decisional conflict, decision aid acceptability, and the PrepDM scale.Results: Four hundred orthopaedic patients completed the questionnaire. The PrepDM scale showed significant correlation with the informed (r = -0.21, p < 0.01) and support (r = -0.13, p = 0.01) subscales (DCS); and discriminated significantly between patients who did and did not find the decision aid helpful (p < 0.0001). Alpha coefficients for internal consistency ranged from 0.92 to 0.96. The scale is strongly unidimensional (principal components analysis) and Item Response Theory analyses demonstrated that all ten scale items function very well.Conclusion: The psychometric properties of the PrepDM scale are very good.Practice Implications: The scale could allow more comprehensive evaluation of interventions designed to prepare patients for shared-decision making encounters regarding complex health care decisions.
