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.
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).
