Standardization of a Diagnostic Battery of Tests for Assessment of Selected Cortical Functions in the Adult Population

Abstract

Developmental Coordination Disorder (DCD) often persists into adulthood. However standardized diagnostic tools for adults remain rare. This study aimed to validate the Czech version of the Adult Developmental Coordination Disorder/Dyspraxia Checklist (ADC) and to standardize a novel battery of tests for assessing practical and gnostic cortical functions. The sample consists of 99 adults (18–40 years; mean age 26.3). Participants underwent a newly designed battery of 11 motor and sensory tests and completed the ADC questionnaire. Reliability was assessed using Cohen’s kappa and Cronbach’s alpha (ɑ). The Czech ADC questionnaire demonstrated excellent internal consistency with the value of Cronbach’s alpha (ɑ=0.93). The test battery showed high inter-rater reliability by Cohen’s kappa (κ=0.89). Deficits were identified in 8–12% of the sample. No significant Cohen’s kappa gender differences were found in objective performance (p > 0.05). The Petrie´’s Test exhibited the highest correlation with subjective self-assessment. The study presents a valid and reliable protocol for screening cortical deficits. The normative data allow the identification of subtle neurodevelopmental impairments in clinical and sports practice in the screening of adult population.
