Adolescents' extensive use of digital devices raises significant concerns about their visual health. This study aimed to adapt and validate the computer vision syndrome questionnaire (CVS-Q) for adolescents aged 12-17 years. A mixed-method sequential design was used. First, a qualitative study was involved two nominal groups to assess the instrument's acceptability. A subsequent cross-sectional quantitative study with 277 randomly selected adolescents assessed reliability and validity. Participants completed the adapted CVS-Q, an ad hoc questionnaire, and the ocular surface disease index (OSDI) questionnaire. Repeatability was tested in 54 adolescents after 7-14 days. The Rasch-Andrich rating scale model was used. Instructions and symptoms were modified to obtain the 14-item CVS-Q teen. It showed unidimensionality, no local dependence between items, and respected monotonicity. Adequate internal consistency (person reliability = 0.69, item reliability = 0.98) and intraobserver reliability (intraclass correlation coefficient = 0.77, Cohen's Kappa = 0.49) were observed. A significant correlation (0.782, p < 0.001) between CVS-Q teen and OSDI supported construct validity. A score of ≥ 6 points indicated computer vision syndrome (CVS) (sensitivity = 85.2%, specificity = 76.5%, and area under the curve = 0.879). In conclusion, CVS-Q teen is a valid and reliable instrument for assessing CVS in adolescents using digital devices, applicable in research and clinical practice for early identification and recommendations for visual health.
青少年广泛使用数字设备引发了对其视觉健康的重大担忧。本研究旨在对12至17岁青少年的计算机视觉综合征问卷（CVS-Q）进行改编和验证。采用了混合方法序列设计。首先，一项定性研究涉及两个名义小组，以评估该工具的可接受性。随后，对277名随机选择的青少年进行了横断面定量研究，以评估其信度和效度。参与者完成了改编后的CVS-Q、一份特设问卷和眼表疾病指数（OSDI）问卷。在54名青少年中于7至14天后测试了重复性。使用了拉施-安德里奇评分量表模型。对说明和症状进行了修改，以获得14项的青少年CVS-Q。它显示出单维性、项目之间无局部依赖性且符合单调性。观察到足够的内部一致性（个人信度=0.69，项目信度=0.98）和观察者内信度（组内相关系数=0.77，科恩kappa系数=0.49）。青少年CVS-Q与OSDI之间存在显著相关性（0.782，p<0.001），支持结构效度。得分≥6分表明存在计算机视觉综合征（CVS）（敏感性=85.2%，特异性=76.5%，曲线下面积=0.879）。总之，青少年CVS-Q是一种有效且可靠的工具，用于评估使用数字设备的青少年的CVS，适用于研究和临床实践，以早期识别和提供视觉健康建议。
