Abstract

Background: The present study aimed to develop and validate a psychological resilience scale for mothers of children with ASD using calibration with the Rasch-Andrich model. Methods: A quantitative approach of national survey research design using an online questionnaire was applied. The cross-sectional study involves a sample of mothers of children with ASD in KSA. Purposive sampling was employed. There were 310 mothers of children with ASD. All of them filled in all questions on the scale. Findings: Concerning unidimensionality and local independence assumptions, the first factor explains more than (20%) of the variance in score with respect to the total variance due to all factors, so it can be said that there is one factor behind the items of the scale. The separation index and reliability of the psychological resilience scale for mothers of children with ASD were at an acceptable level. The person separation reliability was 0.96, indicating an acceptable degree of confidence in replicating the placement of persons within measurement error. Conclusion: Analysis by Item Response Theory (IRT) models allows a considerably deeper understanding of the psychometric properties of the items and scale.

ASD患儿母亲心理弹性量表的编制与验证:Rasch-Andrich模型的校正

背景：本研究旨在使用Rasch-Andrich模型进行校准，开发并验证ASD儿童母亲的心理弹性量表。方法：采用在线问卷的全国调查研究设计定量方法。这项横断面研究涉及KSA ASD儿童的母亲样本。采用目的性抽样。有310名ASD患儿的母亲。他们所有人都填写了量表上的所有问题。研究结果：关于单维度和局部独立性假设，第一个因素解释了所有因素导致的总方差中超过（20%）的得分方差，因此可以说量表项目背后有一个因素。ASD患儿母亲的分离指数和心理恢复力量表的可靠性处于可接受的水平。人员分离可靠性为0.96，表明在测量误差范围内复制人员位置的置信度可接受。结论：通过项目反应理论（IRT）模型的分析可以更深入地理解项目和量表的心理测量特性。

期刊介绍： The journal aims to describe the research work on Intellectual Disability Diagnosis and Treatment in children and adults. It covers not just the technical aspects of the procedures in prenatal, newborn and postnatal screening, but also the impact which the process of testing and treatment has on individuals, parents, families and public-health in general. The journal seeks to publish, but is a not restricted to, Genetic Intellectual Disability Syndromes, using a range of approaches from medicine, psychiatry, psychology, pharmacy, biology, epidemiology, bioinformatics, biopharmaceutical to association and population studies as well as sociological, ethical, philosophical, legal and quality control issues with the ultimate goal of advancing the knowledge on the diagnosis, prevention, and treatment of the Intellectual Disabilities. The journal publishes original research articles, review articles, case reports and short communications(Letter article).
