Summary
Childhood myopia management is enhanced by a new web-based tool supporting shared decision-making (SDM). This Childhood Myopia Shared Decision-Making Aid (CMSDM) improves parental knowledge and reduces regret in treatment choices.
Area of Science:
- Ophthalmology
- Public Health
- Health Informatics
Background:
- Childhood myopia is a growing public health concern, exacerbated by technology use.
- Shared decision-making (SDM) is crucial for effective myopia management and treatment adherence.
Purpose of the Study:
- To develop and evaluate a web-based decision aid for parents regarding childhood myopia treatment.
- To support informed and value-aligned decisions in managing childhood myopia.
Main Methods:
- The Childhood Myopia Shared Decision-Making Aid (CMSDM) was developed following International Patient Decision Aid Standards.
- A two-phase approach included development (scoping, stakeholder engagement) and testing (prototype, alpha/beta testing with 55 parents and 77 healthcare professionals).
Main Results:
- The CMSDM aid demonstrated high content validity (CVI=0.85) and excellent usability (SUS=85).
- Preliminary testing showed CMSDM use significantly improved parental knowledge (p<0.01) and reduced decisional regret (p<0.05).
Conclusions:
- The CMSDM is the first SDM aid specifically for childhood myopia, empowering parents in treatment decisions.
- Further validation through randomized controlled trials is recommended to confirm the effectiveness of the CMSDM tool.
