Cerebral visual impairment (CVI) is an underdiagnosed condition in children, and its assessment tools have focused on older children. We aimed to develop a parental questionnaire for cerebral visual impairment (PQCVI) for screening CVI in young children.
The PQCVI comprised 23 questions based on a modified version of Houliston and Dutton's questionnaire for older children. The PQCVI with neurocognitive function tests was applied to 201 child-parent pairs with typically developing children younger than 72 months (age 32.4±20.1 months, mean±standard deviation). The children were classified into six age groups. The normative data, cutoff scores, and internal reliability were assessed and item analysis was performed. We referred to the total score for all questions as the cerebral visual function (CVF) score.
The normative data showed that the CVF score and the scores corresponding to ventral-stream and dorsal-stream visual functions plausibly increased with age. The scores rapidly reached 90% of their maximum values up to the age of 36 months, after which they increased slowly. Cronbach's alpha for all questions across all age groups was 0.97, showing excellent consistency. The item difficulty and item discrimination coefficients showed that the questions were generally adequate for this age stage.
The PQCVI items produced reliable responses in children younger than 72 months. The rapid increase in scores before the age of 3 years supports the importance of early identification of CVI. Following additional clinical verification, the PQCVI may be useful for CVI screening.
脑性视觉障碍（CVI）在儿童中是一种诊断不足的病症，其评估工具主要针对年龄较大的儿童。我们旨在开发一种用于筛查幼儿脑性视觉障碍的家长问卷（PQCVI）。
PQCVI基于对Houliston和Dutton针对年龄较大儿童的问卷进行修改后的版本，包含23个问题。将PQCVI与神经认知功能测试应用于201对父母及其72个月以下发育正常的儿童（年龄32.4±20.1个月，均值±标准差）。这些儿童被分为六个年龄组。评估了常模数据、临界分数和内部信度，并进行了项目分析。我们将所有问题的总分称为脑视觉功能（CVF）分数。
常模数据显示，CVF分数以及与腹侧视觉流和背侧视觉流功能相应的分数似乎随着年龄增长而增加。在36个月龄之前，分数迅速达到其最大值的90%，之后增长缓慢。所有年龄组所有问题的Cronbach's alpha系数为0.97，显示出极好的一致性。项目难度和项目区分系数表明，这些问题总体上适用于这个年龄阶段。
PQCVI项目在72个月以下儿童中产生了可靠的反应。3岁之前分数的快速增长支持了早期识别CVI的重要性。经过进一步的临床验证后，PQCVI可能有助于CVI筛查。
