Visuoperceptual profiles of children using the Flemish cerebral visual impairment questionnaire.

Abstract:

AIM:To investigate the underlying factor structure of the 46-item Flemish cerebral visual impairment (CVI) questionnaire, differentiate the factor scores of children with and without CVI, and examine the impact of comorbidities on factor scores. METHOD:The records of 630 children (386 males, 244 females; median age 77mo; interquartile range 63-98mo) who visited the CVI clinic and the Centre for Developmental Disabilities at the University Hospitals of Leuven from 2001 to 2018 were reviewed systematically. Inclusion criteria included an up-to-date questionnaire, a definitive diagnosis, and clinical assessment. RESULTS:Three hundred and forty-five children (179 with CVI [108 males, 71 females; median age 74mo; interquartile range 61-93mo] and 166 without CVI [110 males, 56 females; median age 88mo; interquartile range 70-107mo]) were included. An exploratory factor analysis resulted in a 5-factor (object and face processing impairments; visual (dis)interest; clutter and distance viewing impairments; moving in space impairments; and anxiety-related behaviours) biologically and clinically plausible model, which retained 35 items and explained 56% of the total variance. Mann-Whitney U tests indicated that factors 1 to 4 were significantly higher in children with CVI compared to children without CVI (p-values ranged from p<0.001 to p<0.05; effect sizes ranged from 0.11 to 0.33); factor 5 showed no differences. Autism, developmental coordination disorder, epilepsy, and cerebral palsy impacted factor scores. INTERPRETATION:A 5-factor structure of the Flemish CVI questionnaire differentiates children with and without CVI. Comorbidities should be accounted for when researching CVI. WHAT THIS PAPER ADDS:Cerebral visual impairment (CVI) is characterized by impaired object and face processing and impaired visual interest. CVI is also characterized by impaired clutter and distance viewing, and impaired moving in space. All children (with or without CVI) demonstrated anxiety-related behaviours. Autism affected object/face processing, whereas developmental coordination disorder, epilepsy, and cerebral palsy affected visual interest. :Perfis visuoperceptuais de crianças usando o questionário Flemish de deficiência visual cerebral OBJETIVOS: Investigar a estrutura de fator do questionário Flemish de deficiência visual cerebral (DVC) com 46 itens, diferenciar os escores de fator de crianças com e sem DVC, e examinar o impacto de comorbidades nos escores de fator. MÉTODO: Os prontuários de 630 crianças (386 do sexo masculino, 244 do sexo feminino; idade mediana 77m; intervalo interquartil 63-98m;) que visitaram a clínica de DVC e o Centro para Desordens do Desenvolvimento nos Hospitais Universitários de Leuven de 2001 a 2018 foram sistematicamente revisados. Os critérios de inclusão foram um questionário atualizado, um diagnóstico definitivo, e uma avaliação clínica. RESULTADOS: Trezentas e quarenta e cinco crianças (179 com DVC [108 do sexo masculino, 71 do sexo feminino; idade mediana 74m; intervalo interquartil 61-93m] e 166 sem DVC [110 do sexo masculino, 56 do sexo feminino; idade mediana 88m; intervalo interquartil 70-107m]) foram incluídas. Uma análise exploratória de fator resultou em um modelo com 5 fatores (deficiências no processamento de objeto e face; (des)interesse visual; deficiências na visão de espaços abarrotados e distância; deficiências na movimentação no espaço; e comportamentos relacionados a ansiedade) biológica e clinicamente plausível, que reteve 35 itens e explicou 56% da variância total. Os testes U de Mann-Whitney indicaram que fatores de 1 a 4 foram significativamente mais altos nas crianças com DVC comparadas com aquelas sem (valores de p variaram de p<0,001 a p<0,05; os tamanhos de efeito variaram de 0,11 a 0,33); o fator 5 não mostrou diferenças. Autismo, transtorno do desenvolvimento da coordenação, epilepsia e paralisia cerebral impactaram os escores de fator. INTERPRETAÇÃO: Uma estrutura com 5 fatores do questionário Flemish para DVC diferencia crianças com e sem DVC. Comorbidades devem ser consideradas quando se pesquisar a DVC. :Perfis visuoperceptuais de crianças usando o questionário Flemish de deficiência visual cerebral OBJETIVOS: Investigar a estrutura de fator do questionário Flemish de deficiência visual cerebral (DVC) com 46 itens, diferenciar os escores de fator de crianças com e sem DVC, e examinar o impacto de comorbidades nos escores de fator.
