摘要
本研究的目的是使用Rasch模型对沙特阿拉伯ADHD儿童的儿童执行功能量表(CHEXI)进行心理测量分析。该研究包括210名男女儿童(男性和女性)。所有参与者都来自沙特阿拉伯。采用验证性因子分析确定量表的维度结构。Rasch评定量表模型(RSM)在WINSTEPS v. 3.73程序中使用并实现。结果表明,综合数据满足RSM拟合统计的要求。人员和物品与模型的整体契合度很好。人对车西“绝对正确”的高背书率,以及最难的题目,都在地图上名列前茅。在这三个区域中,男性和女性的数量没有差异。满足了系统的单维性和局部独立性要求。反应类别的难度等级按照预期的升序进行校准,并与Andreich的量表模型一致,并且根据两个相关性量表,Infit和Outfit,所有反应类别在统计上都是适当的,其中类别拟合的均方统计(Mnsq)没有超过适合性的限制。车西的阈值在难度上是分级的,在区分度上几乎是相等的,从而满足了评定量表模型的假设。
Psychometric analysis of Childhood Executive Functioning Inventory (CHEXI) in Saudi Arabian ADHD children: Calibration with Rasch model.
The aim of the present study was to examine the psychometric analysis of the Childhood Executive Functioning Inventory (CHEXI) in Saudi Arabian ADHD children using the Rasch model. The study included 210 children from both sexes(males and females). All participants were from Saudi Arabia. Confirmatory factor analysis was performed to determine the dimensional structure of the scale. The Rasch Rating Scale Model (RSM) was used and implemented in the WINSTEPS v. 3.73 program. The results showed that the data, taken together, met the requirements of the RSM fit statistics. A good overall fit of persons and items to the model was found. Persons high rates of endorsement of "definitely true" on the CHEXI, as well as the most difficult items, are at the top of the map. No differences were found between the number of males and females in each of the three areas. The unidimensionality and local independence requirements were met. The levels of difficulty of the response categories are calibrated in ascending order as expected and in agreement with Andreich's scale model, and that all response categories are statistically appropriate according to the two scales of relevance, Infit and Outfit, where the statistics of the mean squares (Mnsq) for the fit of the categories did not exceed the limits of suitability. The thresholds for CHEXI are graded in difficulty and are almost equal in discrimination, and thus the assumption of the rating scale model is fulfilled.
期刊介绍:
Applied Neuropsychology: Child publishes clinical neuropsychological articles concerning assessment, brain functioning and neuroimaging, neuropsychological treatment, and rehabilitation in children. Full-length articles and brief communications are included. Case studies of child patients carefully assessing the nature, course, or treatment of clinical neuropsychological dysfunctions in the context of scientific literature, are suitable. Review manuscripts addressing critical issues are encouraged. Preference is given to papers of clinical relevance to others in the field. All submitted manuscripts are subject to initial appraisal by the Editor-in-Chief, and, if found suitable for further considerations are peer reviewed by independent, anonymous expert referees. All peer review is single-blind and submission is online via ScholarOne Manuscripts.
