Concordance between child and parent-proxy report on a new self-report tool of vision related quality of life for children with JIA-associated uveitis – “Effects of Youngsters’ Eyesight on QOL -EYE-Q”

Purpose

Quality of life (QOL) studies in JIA-associated uveitis (JIA-U) focus on the ocular exam and global measures of QOL. However, these assessments may not accurately measure the impact of visual impairment (VI) on a child’s daily activities. Hence, a child-centered approach is crucial in this assessment. We report on the validity and reliability of a new self-report tool to measure vision related QOL (VRQOL) in children 8-18 years of age, “Effects of Youngsters’ Eyesight on QOL (EYE-Q)”.

Methods

We recruited 120 children, 8-18 years of age, in a pediatric eye clinic. Best corrected visual acuity (VA) was measured using the Snellen chart. Patient-based questionnaires were administered– EYE-Q to measure VRQOL, and Pediatric Quality of Life Inventory (PedsQL) to determine overall QOL. Patients rated their eyesight as excellent (1), good (2), fair (3), poor (4), very poor (5) or completely blind (6). Parents and physicians assessed vision severity and scored how much the child’s life was affected by their vision from 1-10 (1 - vision does not affect function in daily activities, and 10 - vision affects function in daily activities).

Results

Of 120 children, 48% were female, 61% were white, 46.7% had normal vision (both eyes with VA better than 20/40), 54.4% had VI (any eye with VA of 20/40 or worse) and 20.8% required the use of at least one visual aid. Mean age was 11.3 (SD 2.7). Mean scores of the measures in children with VI are shown in Table 1.

Table 1 Mean scores (SD) of measures in children with vision impairment (N=64)

Patient vision assessment had a moderate association with EYE-Q (0.489); mild associations with VI (r = 0.266), VA (r = 0.340), physician vision assessment (r = 0.315), and need for visual aids (r = -0.281); and no association with PedsQL, laterality of VI, and parent vision assessment (Table 2). Parent vision assessment had mild associations with VI (r = 0.280), VA (r = 0.239), EYE-Q (r = -0.297), need for aids (r = -0.281), and physician assessment (r = 0.384); and no association with Peds QL and laterality of VI. Patient vision assessment had stronger associations with the EYE-Q and VA compared to parent vision assessment.

Conclusion

VI can have a significant impact on the VRQOL of children with ocular disease. Our study demonstrates that child-reported VRQOL and vision assessment has good validity but can differ from the parent’s assessment. Both parent and child reports may have valid contributions in the assessment of VRQOL and visual outcome. Hence, the child’s perspective should be included in QOL studies in JIA-U. A vision-specific self-report instrument like the EYE-Q may be an important tool in the assessment of VRQOL in JIA-U, may complement current measures of VI, and may be more valid than measures of overall QOL alone.
