Quality Assessment of Ophthalmic Questionnaires

Abstract

This review provides a descriptive catalog of ophthalmic PRO instruments to inform researchers and clinicians on the choice of the highest-quality PRO instrument suitable for their purpose.

Impact of refractive error on quality of life: a qualitative study

“…Refractive corrections generally reduced these limitations. However, specific issues were affected by type of correction, for example wearing thick rimmed glasses reduced peripheral vision making driving difficult (quotes [11][12][13][14][15][16][17][18][19][20].…”

“…18 Ideally, patient consultation through in-depth interviews or focus group discussions is one of the most important stages of developing the content of a high quality patient-reported outcome (PRO) instrument. 14,15 Surprisingly, these preceding qualitative studies have not been discussed or published in detail for any of the publication that reported the development of the existing refractivespecific PRO instruments.…”

“…13 Patients' viewpoints are crucial in understanding refractive error, in promoting uptake of refraction services and in making choice of refractive corrections. 10,11,[14][15][16] Despite the frequency and magnitude of the burden of refractive error, qualitative literature exploring impact of refractive error on QoL from patients' perspectives is sparse. Qualitative studies often complement quantitative studies.…”

Validation of an instrument to assess visual ability in children with visual impairment in China

“…We chose the CVAQC for this study because it has a content that primarily focuses on school activities, and possesses excellent psychometric properties 7. Moreover, a recent study demonstrated that a meticulously translated CVAQC in the Turkish language formed a valid and reliable measure with robust psychometric properties 15.…”

“…Several PROs have been developed for children with visual impairment 2 9–14. Among all existing PROs, the Cardiff Visual Ability Questionnaire for Children (CVAQC) is considered as one of the highest quality PRO tools in terms of psychometric properties and content coverage 7. The CVAQC assesses the impacts of visual impairment in daily living activities with a special focus on school activities.…”
