A key outcome in aesthetic treatments is the patient's view of how their skin looks and feels after a treatment.
The aim of this study was to add a Treatment Outcome scale to the SKIN-Q patient-reported outcome measure.
Concept elicitation interviews were performed with patients in Canada and the United States. Data were coded, analyzed, and used to draft a Treatment Outcome scale. The scale was refined with patient and expert feedback and field tested in an online sample (ie, Prolific). Psychometric analyses were performed to examine reliability and validity.
The concept elicitation interviews included 26 participants. The first draft of the Treatment Outcome scale included 32 items that assessed changes in appearance (eg, look better) and well-being (eg, feel more confident). Items were revised with input from 12 experts, 11 patients, and 174 online participants who had aesthetic face and/or body treatments and provided 180 survey responses, resulting in 36 items. Prolific data from 499 participants provided 542 assessments. The sample comprised 80.6% women; 78.8% had a facial treatment, 11.4% had a body treatment, and 9.8% had both. Data for a final 10-item Treatment Outcome scale fit the Rasch model (chi-square = 50.46, df = 40, P = .124). The scale evidenced high reliability, with the person separation index, Cronbach α, and intraclass correlation coefficent values ≥.87. A total of 19 out of 22 (86%) predefined construct validation hypotheses were accepted.
This new SKIN-Q scale can be used alongside other patient-centered outcome tools to measure outcomes of minimally invasive aesthetic treatments.
美容治疗的一个关键结果是患者对治疗后皮肤外观和感觉的看法。
本研究的目的是在SKIN-Q患者报告结局量表中增加一个治疗结果量表。
对加拿大和美国的患者进行了概念激发访谈。对数据进行编码、分析，并用于起草治疗结果量表。该量表根据患者和专家的反馈进行了完善，并在一个在线样本（即Prolific）中进行了现场测试。进行了心理测量分析以检验信度和效度。
概念激发访谈包括26名参与者。治疗结果量表的初稿包括32个项目，评估外观变化（如看起来更好）和幸福感（如感觉更自信）。根据12名专家、11名患者和174名接受过面部和/或身体美容治疗并提供了180份调查回复的在线参与者的意见对项目进行了修订，最终形成了36个项目。来自499名参与者的Prolific数据提供了542份评估。样本中80.6%为女性；78.8%接受过面部治疗，11.4%接受过身体治疗，9.8%两者都接受过。最终的10项治疗结果量表的数据符合Rasch模型（卡方=50.46，自由度=40，P=.124）。该量表具有较高的信度，个人分离指数、Cronbach α系数和组内相关系数值≥.87。22个预定义的结构效度假设中有19个（86%）被接受。
这个新的SKIN-Q量表可与其他以患者为中心的结局工具一起使用，以测量微创美容治疗的结果。
