Associations Between DCD Traits, Perceived Difficulties Related to ADHD, ASD, and Reading and Writing Support Needs Among Students in Higher Education: A Pilot Study

Background/Objectives: Since the Act for Eliminating Discrimination against Persons with Disabilities was enacted in 2016, the number of students with disabilities in higher education institutions has increased significantly, creating a greater need for support. Developmental Coordination Disorder (DCD) often coexists with other neurodevelopmental disorders such as Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD), and reading and writing difficulties; yet, awareness of DCD remains low. This study aimed to investigate the prevalence of DCD traits among Japanese higher education students and their relationship with ADHD, ASD, and reading and writing support needs Methods: A pilot study was conducted with 77 university students (mean age: 19.17 +/- 0.68) in the Kansai region, using the Adolescents and Adults Coordination Questionnaire (AAC-Q) to screen for DCD traits, along with a questionnaire assessing difficulties related to ADHD and ASD, and a survey on reading and writing support needs. Results: The study found that 12.9% of students scored more than 1 standard deviation above the mean on the AAC-Q. Students in the DCD trait group (n = 10) reported greater difficulties related to ADHD and ASD than those in the non-DCD group (n = 67). Correlation analysis revealed a moderate-to-strong association between AAC-Q scores and difficulties related to ADHD and ASD among students in the DCD trait group. Conclusions: This study suggests the need to raise awareness about DCD traits and to provide comprehensive support for students with ADHD and ASD in Japanese higher education institutions.
