To develop and validate a short measure of trust in the surgical decision making process.
Having a reliable and valid measure of trust is important to assess the quality of the patient-surgeon relationship when decisions about surgical procedures are made.
A previously published 10-item trust scale was qualitatively tested with patients, and a revised set of 14 items was tested using a web-based survey of 300 people who had hip, knee or back surgery in the past 2 years. The 14 items were evaluated using patterns of correlations and relevance to medical decision making to create a 5-item version. A 5-item subset was compared to the 14-item version to assess reliability and validity of patient's trust in the surgical decision making process.
Of the 300 participants, 32% had hip surgery, 33% had knee surgery, and 34% back surgery. Mean age was 53 years, 45% female, 80% White, and 36% had a high school degree or less. The item intercorrelations for the 14 items were 0.43-0.72 and 0.58-0.71 for the 5 items. Correlation between the versions was 0.96 (P < 0.01). The 14- and 5-item versions were positively correlated with participants' shared decision making process scores (0.42 and 0.41, both P = 0.01), internal consistency reliability scores were 0.95 and 0.89, respectively, and were negatively correlated with their Decision Regret scores (-0.51 and -0.48, both P = 0.01).
The 5-item Trust in the Surgical Decision Scale has strong evidence of validity and reliability for patients who underwent common orthopedic procedures.
开发并验证一种用于外科决策过程中信任的简短测量工具。
当做出手术程序决策时，拥有一种可靠且有效的信任测量方法对于评估医患关系的质量非常重要。
先前发表的 10 项信任量表在患者中进行了定性测试，并使用过去 2 年内接受过髋、膝或背部手术的 300 人的基于网络的调查对 14 项修订后的量表进行了测试。通过相关性模式和对医疗决策的相关性评估，这 14 项量表被评估以创建一个 5 项版本。将 5 项量表与 14 项量表版本进行比较，以评估患者对手术决策过程的信任的可靠性和有效性。
在 300 名参与者中，32%接受了髋部手术，33%接受了膝关节手术，34%接受了背部手术。平均年龄为 53 岁，45%为女性，80%为白人，36%具有高中或以下学历。14 项量表的项目相关性为 0.43-0.72，5 项量表的项目相关性为 0.58-0.71。两个版本之间的相关性为 0.96（P < 0.01）。14 项和 5 项版本与参与者的共同决策过程得分呈正相关（分别为 0.42 和 0.41，均 P = 0.01），内部一致性信度分数分别为 0.95 和 0.89，并且与他们的决策后悔分数呈负相关（分别为-0.51 和-0.48，均 P = 0.01）。
对于接受常见骨科手术的患者，5 项信任手术决策量表具有很强的有效性和可靠性证据。
