This study examined the validity of a new measure of sensory processing for children, the Sensory Processing 3-Dimensions Scale (SP-3D). The SP-3D is a performance-based measure for children ages three to thirteen years, designed to assess sensory processing abilities, and identify the three patterns of sensory processing disorder (SPD) and related subtypes, including sensory modulation, sensory discrimination, and sensory-based motor disorders.
Age trends were explored using descriptive statistics and graphing techniques with a sample of children with and without SPD. SP-3D scores were correlated with scores from the Sensory Processing Measure (SPM) to examine criterion-related validity. Discriminant validity was assessed by comparing SP-3D scores from children with and without SPD.
Age trends of SP-3D scores supported sensory discrimination, praxis and postural functions as developmental constructs. Several mild to moderate correlations were found between the scores of the SP-3D and the SPM, indicating that the tools are measuring similar constructs, and supporting the SP-3D as a measure of sensory processing. Modulation and Motor Behavior Scores from the SP-3D discriminated typically developing children from those with SPD, while results from subtests measuring sensory discrimination, postural and praxis were mixed regarding capacity for discrimination suggesting revision to several items.
The study provides preliminary evidence of the SP-3D as a valid measure of sensory processing abilities and dysfunction. Further research regarding the reliability and validity of the SP-3D are needed.
本研究检验了一种针对儿童的新的感觉加工测量工具——感觉加工三维量表（SP - 3D）的有效性。SP - 3D是一种基于表现的测量工具，适用于3至13岁的儿童，旨在评估感觉加工能力，并识别感觉加工障碍（SPD）的三种模式及相关亚型，包括感觉调节、感觉辨别和基于感觉的运动障碍。
使用描述性统计和绘图技术，对有和没有SPD的儿童样本进行年龄趋势探索。将SP - 3D分数与感觉加工测量量表（SPM）的分数进行相关性分析，以检验效标关联效度。通过比较有和没有SPD的儿童的SP - 3D分数来评估区分效度。
SP - 3D分数的年龄趋势支持将感觉辨别、实践和姿势功能作为发展性结构。在SP - 3D和SPM的分数之间发现了几个轻度到中度的相关性，表明这两种工具测量的是相似的结构，并支持将SP - 3D作为一种感觉加工的测量工具。SP - 3D的调节和运动行为分数能够区分发育正常的儿童和患有SPD的儿童，而在测量感觉辨别、姿势和实践的子测试结果中，关于区分能力的结果则好坏参半，这表明需要对几个项目进行修订。
该研究为SP - 3D作为感觉加工能力和功能障碍的有效测量工具提供了初步证据。需要对SP - 3D的信度和效度进行进一步研究。
