Although screeners such as the Adolescents and Adults Coordination Questionnaire (AAC-Q) are widely used elsewhere, recognition and support for DCD in Japan remain limited. This study examined associations among DCD traits, ADHD\/ASD-related difficulties, learning difficulties, mental health difficulties, and lifestyle factors in university students. Methods: We conducted a web-based survey of 16,295 students; responses from 527 were analyzed. The instruments used for the analysis included the AAC-Q, short forms of ADHD and ASD Difficulty Scales, the 7-item Learning Difficulty Scale for Postsecondary Students and 10-item Scale for Childhood Learning Difficulties, and the University Personality Inventory (UPI). Nonparametric and Spearman\u2019s rank correlations were performed. Results: DCD traits were observed at 7.4% (AAC-Q \u2265 32). This is a screen-positive proportion only. AAC-Q scores correlated strongly with ADHD difficulties (r = 0.65), moderately to strongly with ASD difficulties (r = 0.55), and moderately with mental health difficulties measured by the UPI (r = 0.41). Conclusions: These findings suggest that identifying DCD traits at university entry may be associated with greater student self-understanding and improved access to appropriate support. They support targeted DCD screening alongside ADHD\/ASD screening at university entry, rather than universal screening.<\/jats:p>","DOI":"10.3390\/brainsci15080895","type":"journal-article","created":{"date-parts":[[2025,8,22]],"date-time":"2025-08-22T12:31:26Z","timestamp":1755865886000},"page":"895","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Associations Among Developmental Coordination Disorder Traits, Neurodevelopmental Difficulties and University Personality Inventory Scores in Undergraduate Students at a Japanese National University: A Cross-Sectional Correlational Study"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3660-9489","authenticated-orcid":false,"given":"Masanori","family":"Yasunaga","sequence":"first","affiliation":[{"name":"Health and Counseling Center, The University of Osaka, Toyonaka 560-0043, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryutaro","family":"Higuchi","sequence":"additional","affiliation":[{"name":"Health and Counseling Center, The University of Osaka, Toyonaka 560-0043, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keita","family":"Kusunoki","sequence":"additional","affiliation":[{"name":"Student Support Center, Bukkyo University, Kyoto 603-8301, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoto","family":"Mochizuki","sequence":"additional","affiliation":[{"name":"Health and Counseling Center, The University of Osaka, Toyonaka 560-0043, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,21]]},"reference":[{"key":"ref_1","unstructured":"(2013).
