This study established normative data for the Czech Neuropsychological Test Battery (UDS-Cz 2.0) in an aging population. Cognitive performance declines with age, but higher education offers protection, informing clinical assessments.
Area of Science:
- Neuropsychology
- Gerontology
- Psychometrics
Background:
- International normative data for neuropsychological tests are limited.
- The Uniform Data Set (UDS) is sensitive for evaluating cognitive aging and decline.
- The UDS-Cz 2.0 is a Czech adaptation of the UDS neuropsychological test battery.
Purpose of the Study:
- To assess the feasibility of the Czech Neuropsychological Test Battery (UDS-Cz 2.0).
- To evaluate UDS-Cz 2.0 performance from an international perspective.
- To establish normative data for the UDS-Cz 2.0 in the Czech Republic.
Main Methods:
- Data collected from 520 cognitively normal Czech participants.
- Regression analyses used to identify demographic influences on test performance.
- Normative data adjusted for age and education level.
Main Results:
- Cognitive performance decreased with advancing age across all measures.
- Higher education levels demonstrated a protective effect on cognitive function.
- Normative values for the UDS-Cz 2.0 were established.
Conclusions:
- The UDS-Cz 2.0 is psychometrically sound for the aging Czech population.
- Normative data are now available for clinical use in the Czech Republic.
- Age and education are key demographic factors influencing cognitive performance on the UDS-Cz 2.0.

Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...
