Future studies with adequate sample sizes and sophisticated GAD categories will be needed.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jdn.10330","type":"journal-article","created":{"date-parts":[[2024,4,19]],"date-time":"2024-04-19T06:54:32Z","timestamp":1713509672000},"page":"281-292","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Grey
