中文摘要
背景： 尽管用于嗓音健康的移动健康（mHealth）工具日益增多，但其科学评估仍然有限。
目的： 评估教师对 Vocal'iz 移动应用程序的感知可用性和有用性。考察这些结果与年龄、嗓音障碍指数（VHI-30）、健康素养和数字素养等个体因素之间的关系。
方法： 三十名教师参与了本研究的三个阶段：（1）完成个人数据问卷、VHI-30、健康素养量表和数字素养量表；（2）独立使用该应用程序 10 天；（3）完成系统可用性量表（SUS）和移动应用评定量表（MARS）F 部分，以评估该应用程序的可用性和感知有用性。采用单样本 t 检验将参与者的 SUS 评分与参考值 70 进行比较。采用 Wilcoxon 符号秩检验将 MARS F 部分评分与参考值 3 进行比较。在 SUS 和 MARS 评分与个体因素之间进行了相关性检验。
结果： SUS 平均评分（76.67，SD = 11.55）和 MARS F 部分平均评分（4.03，SD = 0.74）均显著高于参考值，效应量为中等至较大。可用性或有用性与个体因素之间均无显著相关性。
结论： 研究结果表明，教师对 Vocal'iz 应用程序的评价很高，显示出其良好的可用性和积极的感知有用性。该应用程序作为预防工具的潜力值得在更多样化和更大的人群中进一步评估，同时也需要评估其有效性。
英文摘要
BACKGROUND: Although mobile health (mHealth) tools for vocal health are increasingly used, their scientific evaluation remains limited.
OBJECTIVES: To assess the perceived usability and usefulness of the Vocal'iz mobile application among teachers. To examine the relationships between these outcomes and individual factors such as age, Voice Handicap Index (VHI-30), health literacy, and digital literacy.
METHOD: Thirty teachers participated in the three phases of our study: (1) completion of a personal data questionnaire, the VHI-30, the Health Literacy Scale, and the Digital Literacy Scale; (2) 10 days of independent use of the application; and (3) completion of the System Usability Scale (SUS) and section F of the Mobile App Rating Scale (MARS) to assess the app's usability and perceived usefulness. A one-sample t-test compared the participants' SUS score to the reference value of 70. A Wilcoxon signed-rank test compared the MARS section F score to the reference value of 3. Correlation tests were conducted between the SUS and MARS scores and the individual factors.
RESULTS: The mean SUS score (76.67, SD = 11.55) and the mean score for MARS section F (4.03, SD = 0.74) were both significantly higher than the reference values, with medium to large effect sizes. There were no significant correlations between usability or usefulness and the individual factors.
CONCLUSIONS: The findings suggest that teachers rated the Vocal'iz app highly, demonstrating its good usability and positive perceived usefulness. The app's potential as a preventive tool warrants further evaluation in more diverse and larger populations, as well as an assessment of its effectiveness.
