The aim of the present study was to examine feasibility and validity of the Boston Naming Test (BNT) Czech version.

An evaluation of confrontation naming is a substantial part of neuropsychological assessment. The BNT is one of the most widely used standardized measures of confrontation naming. However, a feasibility and validity study in the Czech population is still lacking. Patients and methods: We administered the BNT-60 and a broad neuropsychological battery to 154 subjects. A control sample (CS) consisted of 64 healthy subjects and a clinical sample of 52 Parkinson’s disease patients with mild cognitive impairment (PD-MCI) and 38 PD patients without cognitive impairment (PD-NI).

Age and education are significantly related to the BNT-60 total score (age: Spearman ρ = –0.162; p = 0.045, education: ρ = 0.295; p < 0.001). Significant differences were revealed in all BNT scores between CS and PD-MCI (all p values < 0.05), while the only score that significantly differed between CS and PD-NI was the number of correct answers after semantic cue. BNT did not significantly differ between clinical groups. We found the highest convergent validity between BNT-60 and National Adult Reading Test Czech version (ρ = 0.476; p < 0.001). Cronbach’s alpha, as an internal consistency measure, was 0.746.

Our results replicated the association between the BNT-60 Czech version and age and education in comparison to the original and suggest satisfactory discriminative validity for the differentiation between CS and PD-MCI. Our study presents preliminary percentile values in the Czech population and cutoffs for PD-MCI.

Key words:
Boston Naming Test Czech version – mild cognitive impairment – Parkinson’s disease – validity
