Objective: This study aimed to investigate the factor structure of the Coimbra Neuropsychological Assessment Battery (BANC), which is an individually administered battery designed to assess a wide range of neurocognitive functions in children. Method: Using the standardization sample of the BANC, a confirmatory factor analysis and a multiple-group analysis were conducted to examine the factor structure and the measurement invariance of three main domains (Memory, Language, and Attention/Executive Functions) in 833 children aged 7-15 years. Results: Consistent with the BANC's conceptualization, the three-correlated-factor model demonstrated the most adequate fit to the data. The measurement invariance of the three-correlated-factor model across two age-groups (7-9 years and 10-15 years) was supported (configural, metric, and partial scalar invariance). Conclusion: Overall, the BANC shows adequate psychometric properties and provides useful information regarding the children's neuropsychological functioning. [ABSTRACT FROM AUTHOR]

The Clock Drawing Test has been systematically used to assess visuospatial deficits related to the parietal lobes, but we now acknowledge its much more complex relation with other cognitive abilities. Despite its common use in clinical and investigational practices, no study has developed normative data for the Portuguese population. We present the distribution of clock drawing scores using three scoring systems in a representative community sample of cognitively healthy subjects. We found that the systems were well correlated with each other and with cognitive screening tests widely used and had good psychometric properties. Normative data for the three scoring systems were developed considering age and education. These results allow a more rigorous interpretation of the test performance in clinical context and are especially relevant for epidemiological research. [ABSTRACT FROM AUTHOR]
