WITHDRAWAL — Administrative Duplicate Publication: Prevalence of ADHD Symptomatology in Adult Population in the Czech Republic: A National Study

Abstract

Background: ADHD is a common neurodevelopmental disorder frequently diagnosed between the ages 7 and 10 years. We measured ADHD symptomatology in a representative sample of the Czech population. Material and Methods: Data collection was performed in January 2019 through the European National Panel. The respondents completed a demographic questionnaire focusing on ADHD history and a standardized questionnaire, the Adult ADHD Self-Report Scale (ASRS) screener for ADHD symptomatology in adulthood. Results: From the sample of 1,518 respondents, 3% of the respondents reported having been diagnosed with ADHD/hyperkinetic disorder in their lifetime. According to ASRS scoring, 119 respondents were classified as suspected ADHD. Overall, more males than females reported ADHD symptomatology. Age was also significantly associated with ASRS. Education status yielded no significant results. Conclusion: Our study documents that the prevalence of ADHD symptomatology in adults is comparable with that in Western countries despite the different historical and health care backgrounds.

Childhood School Performance in Adults Diagnosed with Attention-Deficit/Hyperactivity Disorder

“…In the Czech school system, all of these notes and reprimands are written down along with other grades that the students receive, and parents have to be notified about this and have to sign them—a way of checking that they were told about their child’s behavior at school. For a more detailed description of the methodology, see Vňuková et al (2021). The data were analyzed with the statistical software R (R Core Team, 2022).…”
