Visual complaints are a common consequence of acquired brain injury (ABI). Yet, they may be overlooked in clinical practice. The present study aims to develop a screening instrument for assessing visual complaints in individuals with ABI and evaluate its psychometrics properties in a community sample.
We constructed the Dutch Screening Visual Complaints questionnaire-acquired brain injury (SVCq-abi), a self-report 23-item questionnaire. A Dutch community sample of 1159 participants (Mean [SD] age, 60 [16] years) completed the SVCq-abi and other questionnaires on visual disturbances, executive functioning, mental health, and autistic traits. Confirmatory factor analyses were performed for 5 models (1-factor, 3-factor, 5-factor, second-order, and bifactor) on a random split of half of the sample, and cross-validated on the other half. In addition, we evaluated floor and ceiling effects, scale reliability, test-retest reliability, as well as convergent and divergent validity.
A 5-factor structure of the SVCq-abi was adopted which showed an excellent model of fit, with all item loadings exceeding 0.5. The SVCq-abi subscales demonstrated various floor effects, acceptable scale reliability, moderate to good test-retest reliability (ICC = 0.65 to 0.73), along with sufficient convergent (r2 = 9% to 32%) and divergent validity (r2 = 2% to 13%).
The SVCq-abi shows fundamental psychometric properties and the factor analysis provides support for a 5-factor structure. Further validation of the SVCq-abi in individuals with ABI is essential.
视觉障碍是获得性脑损伤（ABI）的常见后果。然而，在临床实践中它们可能被忽视。本研究旨在开发一种筛查工具，用于评估ABI患者的视觉障碍，并在社区样本中评估其心理测量学特性。
我们构建了荷兰语版的获得性脑损伤视觉障碍筛查问卷（SVCq-abi），这是一份包含23个条目的自评问卷。一个由1159名参与者组成的荷兰社区样本（平均[标准差]年龄，60[16]岁）完成了SVCq-abi以及其他关于视觉障碍、执行功能、心理健康和自闭症特征的问卷。对样本的一半进行随机划分后，对5种模型（单因素、三因素、五因素、二阶和双因素模型）进行验证性因素分析，并在另一半样本上进行交叉验证。此外，我们评估了地板效应和天花板效应、量表信度、重测信度以及聚合效度和区分效度。
采用了SVCq-abi的五因素结构，该结构显示出极佳的拟合模型，所有项目负荷均超过0.5。SVCq-abi分量表表现出不同程度的地板效应、可接受的量表信度、中等至良好的重测信度（组内相关系数=0.65至0.73），以及足够的聚合效度（r2=9%至32%）和区分效度（r2=2%至13%）。
SVCq-abi显示出基本的心理测量学特性，因素分析为五因素结构提供了支持。对ABI患者进一步验证SVCq-abi至关重要。
