Abstract
Purpose :
To develop a new pediatric eye treatment questionnaire (PedEyeQ-T), designed to assess the impact of non-surgical eye treatments on function and on eye-related quality of life (ER-QOL) in children under the age of 18 with a variety of eye conditions and eye treatments.
Methods :
Child and Proxy master questionnaires were created from specific concerns identified from child and parent interviews. Child master questionnaires (n=34 items), were administered to children (5-17 years old; n=329) currently undergoing any non-surgical eye treatment (glasses, contact lenses, patching, drops, binocular amblyopia treatment, etc.), and Proxy master questionnaires (n= 34 items) were administered to one parent for each child (0-17 years old; n=466). A 3-level frequency rating scale (never, sometimes, always) was used for responses. Exploratory factor analyses were performed to identify domains within function-related items (n=7) and ER-QOL-related items (n=27), labeled based on review of content. Rasch analysis was performed on each domain identified in factor analysis, to reduce items by evaluating differential item functioning (sex, race, age, parent completing), response ordering, local dependence, fit, and targeting.
Results :
Factor analysis of Child questionnaires identified 1 domain for function-related items and 2 domains for ER-QOL items. Rasch analysis confirmed unidimensionality of domains and yielded a Child questionnaire with 3 items in a Treatment: Function domain, 10 items in a Treatment: Socioemotional domain, and 6 items in a Treatment: Difficulty domain. For the Proxy questionnaire, Factor analysis identified 1 domain for function-related items and 2 domains for ER-QOL items. Following Rasch analysis the Proxy treatment questionnaire had 3 items in a Treatment: Function domain, 7 items in a Treatment: Socioemotional domain, and 3 items in a Treatment: Difficulty domain.
Conclusions :
By following a rigorous process for questionnaire development, we have created the new patient-derived Pediatric Eye Treatment Questionnaire (PedEyeQ-T), for use in children of any age undergoing any non-surgical eye-treatment, with Child and Proxy versions for assessing impact on function and on ER-QOL.
