7-16 Yaş Serebral Palsili Çocuklarda Serebral Görme Bozukluğu ile İlişkili Değerlendirme Süreçlerinin Oluşturulması

Abstract

This study aimed to examine the psychometric properties of questionnaires related to cerebral visual impairment (CVI) in school-age children with cerebral palsy (CP) and to propose a motor functioning-based application process for occupational therapists and other specialists working in the field. A total of 288 children with CP were included in the study. The presence of CVI in all children included in the study was determined using the clinical decision-making process and the CVI Motor Questionnaire (CVI-MQ). The daily visual performance of the children was assessed using the CVI Inventory and the Functional Vision Questionnaire (FVQ), considering the Gross Motor Function Classification System (GMFCS). Receiver operating characteristic (ROC) analysis was applied to determine the sensitivity and specificity of CVI-MQ. The construct validity of the CVI Inventory and FVQ was investigated by Exploratory Factor Analysis (EFA). The appropriateness of the application process was examined by the performance of the factor scores obtained from the CVI Inventory and FVQ in predicting the visual function classification system. As a result of the ROC analysis conducted for the CVI-MQ, a specificity of 0.89 and a sensitivity of 0.94 were obtained for the CVI-MQ GMFCS I-III form, while a specificity of 0.92 and a sensitivity of 0.97 were found for the GMFCS IV-V form. The EFA conducted for the CVI Inventory suggested a four-factor solution explaining 53% of the variance. On the other hand, EFA conducted for the FVQ suggested a one-factor structure explaining 71% of the variance. The one-factor structure of the FVQ and the two factors extracted from the CVI Inventory predicted visual functioning in the range of 57-88% and 51-67%, respectively. In conclusion, it was found that specific questionnaires related to CVI, administered with the GMFCS in mind, can be valuable tools for occupational therapists to assess daily visual performance.
