November 17, 2025 updated by: National Taiwan University Hospital

Unmet Needs, Barriers and Facilitators to Vision Services for Children and Adolescents With Special Vision Care Needs: A Mixed-Model Design Study

Children and adolescents with special needs, compared to those with general development, have a much higher incidence of visual impairments (10.5% vs. 0.16%). This project will focus on "children and adolescents with special visual care needs", comprehensively exploring their unmet needs in ophthalmology and visual care, as well as the obstacles and facilitators they may encounter in the process of seeking ophthalmic services.

The purposes of this study will investigate the current needs of children and adolescents with special visual care needs in ophthalmology and visual medical services, and the obstacles and potential facilitators encountered by children and adolescents with special visual care needs in the process of obtaining ophthalmology and visual medical services.

Detailed Description

The research will center on children and adolescents with special visual needs and explore the research questions from various stakeholders' perspectives, including parents, special education teachers and experts, healthcare professionals, workers from related NGOs and government units. A mixed-methods research approach will be used to gather both quantitative and qualitative data. After data analysis, a comparison and interpretation between the two results will be conducted to obtain the final research outcomes.

  1. Quantitative research: Two-part questionnaire. The first part collects background information, and the second part is a "Needs and Difficulties Survey", framed by Levesque et al.'s conceptual framework of access to healthcare.
  2. Qualitative research: The first part consists of semi-structured in-depth interviews, and the second part uses the focus group method. Both parts will use a common interview guideline and the International Classification of Functioning, Disability and Health, Child & Youth Version (ICF-CY) as the theoretical framework.
