Summary
The improved Chinese mHealth App Usability Questionnaire (I-C-MAUQ) is reliable and valid for assessing mobile health app usability in China. This validated tool helps evaluate patient-facing apps, confirming the mHealth App Usability Questionnaire
Area of Science:
- Health Informatics
- Human-Computer Interaction
- Cross-cultural Adaptation of Health Technologies
Background:
- Mobile health (mHealth) app usability requires rigorous evaluation before clinical deployment.
- The mHealth App Usability Questionnaire (MAUQ) is a validated tool for assessing mHealth app usability.
- Cross-cultural adaptation and validation are essential for international mHealth app usability assessments.
Purpose of the Study:
- To adapt and validate the Chinese version of the MAUQ (C-MAUQ) for interactive patient-facing mHealth apps.
- To test the reliability and cross-cultural adaptability of the improved C-MAUQ (I-C-MAUQ) on the 'Left-handed Doctor' app.
- To evaluate the usability of the 'Left-handed Doctor' mHealth app using the I-C-MAUQ.
Main Methods:
- Translation and cultural adaptation of the MAUQ into Chinese, followed by validation on the 'Good Doctor' app.
- Refinement of the C-MAUQ based on the original English version and expert review to create the I-C-MAUQ.
- Online survey of 322 participants on 'wenjuanxing' to assess the I-C-MAUQ's internal consistency, reliability, and validity.
Main Results:
- The I-C-MAUQ retained the original 21 items and 3 dimensions of the MAUQ.
- Significant improvements were made to address translation issues in the C-MAUQ, enhancing comprehensibility and cultural relevance.
- The I-C-MAUQ demonstrated excellent internal consistency (0.861-0.938), reliability (Cronbach α=.988), and validity (KMO=0.973).
Conclusions:
- The I-C-MAUQ is a highly reliable and valid instrument for evaluating interactive mHealth apps in China.
- The study confirms the cross-cultural validity, reliability, and adaptability of the MAUQ.
- User demographics (age, gender, education, profession) and prior experience influence perceived mHealth app usability, with younger Chinese females showing higher acceptance.
