Measurements of patients' perceptions of the benefits, costs, and risks of orthognathic treatment are needed to assess the utility of alternative treatments, and to assess and improve patient education to make informed decisions. A two-part study was conducted to develop and evaluate measures assessing patients' perceptions of the benefits and risks of orthognathic surgery in comparison to an orthodontics-only approach or no treatment. The first part of this study included 49 patients who had completed orthodontics and orthognathic surgery and 34 patients considering orthognathic surgery. All patients were asked to complete an open-ended telephone questionnaire about their perceptions of the benefits and risks of orthognathic surgery and of alternative options. Patients' answers were sorted into categories, and the second part of this study included a closed-form written questionnaire to assess the perceived likelihood of possible outcomes in each category. Reliability of the questionnaire was assessed using Cronbach's alpha coefficient of internal consistency reliability. Cronbach's alpha ranged from 0.74 to 0.91 when the instrument was used to assess either overall benefits or risks of orthognathic surgery, orthodontics only, or no treatment, indicating acceptable reliability for each of these uses. Subscales concerning more narrowly defined aspects of benefits and risks were less reliable than the overall scales.
需要对患者关于正颌治疗的益处、成本和风险的认知进行测量，以评估替代治疗的效用，并评估和改进患者教育，使其能够做出明智的决策。我们开展了一项分为两部分的研究，旨在开发和评估一些测量方法，以评估患者对正颌手术相较于单纯正畸治疗或不治疗的益处和风险的认知。该研究的第一部分纳入了49例已完成正畸和正颌手术的患者以及34例考虑进行正颌手术的患者。所有患者均被要求完成一份开放式电话调查问卷，内容涉及他们对正颌手术以及替代方案的益处和风险的认知。患者的回答被分类整理，研究的第二部分包括一份封闭式书面问卷，用于评估每个类别中可能结果的感知可能性。使用Cronbach内部一致性信度系数评估问卷的信度。当该工具用于评估正颌手术、单纯正畸治疗或不治疗的总体益处或风险时，Cronbach's alpha系数范围为0.74至0.91，表明这些用途的信度均可接受。关于益处和风险更狭义定义方面的分量表不如总体量表可靠。
