Background:
While several scales assess functional impairment in pediatric Attention-deficit hyperactivity disorder (ADHD), there remains a paucity of well-validated measures specifically designed to evaluate impairment severity across multiple functional domains. This study aims to develop a novel scale for evaluating the severity of ADHD in children and to analyses its reliability and validity.
Methods:
A preliminary pool of items was created based on a literature review and some expert opinions. Exploratory factor analysis, along with internal consistency, and reliability tests were conducted.
Results:
We developed a 7-item severity assessment scale specifically designed for pediatric ADHD, which serves as a brief parents-report measure of ADHD severity by evaluating its functional impacts. The confirmatory sample included 81 parents of children diagnosed with ADHD, aged 6-14 years. Through exploratory factor analysis revealed a one-factor structure, indicating the scale's overall goodness of fit. The scale exhibited strong internal consistency with a Cronbach's α of 0.83. Additionally, it demonstrated significant content validity, convergent validity, and discriminant validity.
Conclusion:
These findings demonstrated that the 7-item severity assessment scale for pediatric ADHD is a valid and reliable instrument. Future research should employ this scale to accurately measure the severity of ADHD in children.
