Patient-reported outcome (PRO) instruments measure health status in a variety of domains. With the proliferation of mobile phones, delivering PROs across patient-friendly platforms (eg, apps, text messaging) may increase completion rates, particularly among children. The purpose of this study was to validate the collection of common knee PROs in sports medicine with text messaging by correlating text-messaging responses with paper delivery in adolescents.
Patients presenting to a hospital-based pediatric orthopaedic sports medicine clinic with a knee injury were enrolled prospectively. Paper versions of the Pediatric International Knee Documentation Committee (Pedi-IKDC) Subjective Knee Evaluation Form and the Pediatric Functional Activity Brief Scale (Pedi-Fab Scale) were completed during initial clinic visits. Over the next 72 hours, patients completed the text message delivery of the Pedi-IKDC and Pedi-Fab Scale. Correlations between paper and text message delivery of the 2 PROs were assessed.
Ninety-one patients (mean age: 16.0±2.0 y; 48% females) enrolled in the text-messaging study, with 55 (60.4%) completing the Pedi-Fab Scale, 48 (52.7%) completing the Pedi-IKDC, and 39 (42.9%) completing both PROs. The intraclass correlation coefficient between the paper and mobile phone delivery of the Pedi-Fab Scale was 0.95 (P<0.001; 95% confidence interval, 0.91-0.97). The intraclass correlation coefficient between the paper and mobile phone delivery of the Pedi-IKDC was 0.96 (P<0.001; 95% confidence interval, 0.93-0.98). Average Pedi-Fab scores on paper (M=12.7) and mobile phone (M=12.3) were not significantly different (P=0.52). Similarly, average Pedi-IKDC scores on paper (M=68.8) and mobile phone (M=67.7) were not significantly different (P=0.41). Average completion time for the text delivered Pedi-Fab and Pedi-IKDC were 102±224 and 159±155 minutes, respectively. High school enrollment (P=0.025), female sex (P=0.036), and race (P=0.002) were significantly associated with text completion of Pedi-IKDC.
Text message delivery using mobile phones permits valid assessment of Pedi-IKDC and Pedi-Fab scores in adolescents. Questionnaire delivery by automated text messaging allows asynchronous response and may increase compliance and reduce the labor cost of collecting PROs.

患者报告结局（PRO）工具可在多个领域衡量健康状况。随着手机的普及，通过患者友好型平台（如应用程序、短信）收集PROs可能会提高完成率，尤其是在儿童中。本研究的目的是通过将青少年短信回复与纸质问卷回复进行关联，验证通过短信收集运动医学中常见膝关节PROs的方法。
前瞻性纳入在一家医院的儿科骨科运动医学诊所就诊的膝关节损伤患者。在初次门诊就诊时完成纸质版的儿科国际膝关节文献委员会（Pedi-IKDC）主观膝关节评估表和儿科功能活动简表（Pedi-Fab量表）。在接下来的72小时内，患者通过短信完成Pedi-IKDC和Pedi-Fab量表的填写。评估这两种PROs纸质问卷和短信回复之间的相关性。
91名患者（平均年龄：16.0±2.0岁；48%为女性）参与了短信研究，其中55名（60.4%）完成了Pedi-Fab量表，48名（52.7%）完成了Pedi-IKDC，39名（42.9%）完成了两种PROs。Pedi-Fab量表纸质问卷和手机回复之间的组内相关系数为0.95（P<0.001；95%置信区间，0.91-0.97）。Pedi-IKDC纸质问卷和手机回复之间的组内相关系数为0.96（P<0.001；95%置信区间，0.93-0.98）。Pedi-Fab量表纸质问卷（M=12.7）和手机回复（M=12.3）的平均得分无显著差异（P=0.52）。同样，Pedi-IKDC纸质问卷（M=68.8）和手机回复（M=67.7）的平均得分无显著差异（P=0.41）。通过短信发送的Pedi-Fab和Pedi-IKDC的平均完成时间分别为102±224分钟和159±155分钟。高中入学（P=0.025）、女性（P=0.036）和种族（P=0.002）与Pedi-IKDC的短信完成情况显著相关。
使用手机短信发送可有效评估青少年的Pedi-IKDC和Pedi-Fab得分。通过自动短信发送问卷允许异步回复，可能会提高依从性并降低收集PROs的劳动力成本。
