Our study revealed that the validity of a new Japanese visual-perceptual test was acceptable. Visual-perceptual abilities are important to activities of daily living; thus, accurate assessment of visual perception is especially important for children with neurodevelopmental disorders and particularly so for those with learning problems.
Visual perception refers to the process by which one receives visual information through sensory impulses and then translates those impulses into meaning based on a previously developed view of the environment. A problem in Japan is the paucity of visual perception tests that use normative data from children who are native Japanese. The Wide-range Assessment of Vision-related Essential Skills (WAVES), which measures visual perception and eye-hand coordination skills and is based on Japanese normative data, was recently published in Japan. The validity of this test has not been comprehensively established.
To investigate the validity of the WAVES, we used the Pearson correlation coefficient to calculate the degrees of association among WAVES scaled and index scores compared with Developmental Test of Visual Perception, Third Edition, scores from 108 elementary school children with symptoms of learning problems. Participants were recruited at Osaka Medical College Learning Disability Center and Sakai Seikeikai Learning Disability Center.
The concurrent validity of the WAVES was supported by moderate correlation (r = 0.67, P < .01) between the total scores for visual perception and eye-hand coordination index from the WAVES and general visual perception index from the Developmental Test of Visual Perception, Third Edition, even though a correlation analysis of subtests found differences between the two tests.
Our results showed that the indices from the two tests measured nearly the same underlying visual-perceptual constructs and indicated that the WAVES had acceptable levels of concurrent validity.
我们的研究表明，一种新的日本视觉感知测试的有效性是可以接受的。视觉感知能力对日常生活活动很重要；因此，准确评估视觉感知对于神经发育障碍的儿童，尤其是有学习问题的儿童尤为重要。
视觉感知是指通过感官冲动接收视觉信息，然后根据先前对环境的看法将这些冲动转化为意义的过程。日本存在的一个问题是，缺乏使用日本本土儿童的规范数据的视觉感知测试。WAVES（广泛的视觉相关基本技能评估）最近在日本出版，它衡量视觉感知和手眼协调技能，并且基于日本的规范数据。该测试的有效性尚未得到全面证实。
为了研究 WAVES 的有效性，我们使用 Pearson 相关系数计算了 WAVES 量表和指数得分与来自 108 名有学习问题症状的小学生的第三版发展性视觉感知测试得分之间的关联程度。参与者是在大阪医科大学学习障碍中心和坂井清海学习障碍中心招募的。
WAVES 的视觉感知和手眼协调指数总分与第三版发展性视觉感知测试的一般视觉感知指数之间存在中度相关性（r = 0.67，P <.01），支持了其同时效度，尽管对子测试的相关性分析发现了这两个测试之间的差异。
我们的结果表明，这两个测试的指标几乎测量了相同的潜在视觉感知结构，并表明 WAVES 具有可接受的同时效度。
