- Normative data for tests of attention and executive functions in a sample of European Portuguese adult populationPublication . Vicente, Selene G.; Rivera, Diego; Barbosa, Fernando; Gaspar, Nuno; Dores, Artemisa Rocha; Mascialino, Guido; Arango-Lasprilla, Juan CarlosThe main goal of this study was to produce normative data for the Portuguese population on five neuropsychological tests frequently used to assess executive functions and attention: the Modified Wisconsin Card Sorting Test (M-WCST), the Stroop Color and Word Test, the Trail Making Test (TMT), the Brief Test of Attention (BTA), and the Symbol Digit Modalities Test (SDMT). The study included 300 individuals aged between 18 and 93 years, who had educational backgrounds ranging from 3 to 25 years. The influence of age, education, and sex was explored for each measure, as well as their contribution to explain the performance variance. Conclusions: The normative data are presented as regression-based algorithms to adjust direct and derived test scores for sex, age, and education. This study provides a calculator of normative data, derived from the results of the regression models.
- Normative data for verbal fluency and object naming tests in a sample of European Portuguese adult populationPublication . Vicente, Selene G.; Benito-Sánchez, Itziar; Barbosa, Fernando; Gaspar, Nuno; Dores, Artemisa R.; Rivera, Diego; Arango-Lasprilla, Juan CarlosThe purpose of the present study was to calculate the construct validity, internal consistency and normative data of the Phonological Verbal Fluency Test (letters F, A, S, and M), Semantic Verbal Fluency Test (Animals, Fruits and Professions categories), and Boston Naming Test (short and standard version), and to generate normative data for these tests after adjusting for age, education, and sex. A sample of 293 European Portuguese adults participated in the study. Results showed adequate construct validity and internal consistency for all of the tests and the final multiple regression models found that age and education were significantly associated with P-VFT (letters F, A, S, and M), S-VFT (Animals, Fruits and Professions categories), and BNT performance. Sex was only found to have an effect on the fruit category, with women scoring higher than men. The normative data provided in this study will contribute to improving the clinical practice of neuropsychology in Portugal.
- Regression-based norms for the Hopkins verbal learning test-revised and the Rey–Osterrieth complex figure in a portuguese adult populationPublication . Vicente, Selene G.; Ramos-Usuga, Daniela; Barbosa, Fernando; Gaspar, Nuno; Dores, Artemisa Rocha; Rivera, Diego; Arango-Lasprilla, Juan CarlosThe principal goal of this study was to produce adjusted normative data for European Portuguese native speakers from Portugal on 2 neuropsychological tests widely used to assess learning and memory: the Hopkins Verbal Learning Test-Revised (HVLT-R) and the Rey–Osterrieth Complex Figure Test (ROCF). The study included 300 individuals aged 18–92 years (M = 50.4, SD = 21.2), who had educational backgrounds ranging from 3 to 25 years (M = 10.4, SD = 5.2). Age, education, and sex were significantly associated with HVLT-R and ROCF performance. These demographic variables accounted for 61% of the variance in HVLT-R total recall, 54% in HVLT-R delayed recall, 18% in HVLT-R recognition, 55% in ROCF copy, and 39% in ROCF immediate recall. The normative data are presented as regression-based algorithms to adjust direct and derived test scores for age, education, and sex. This study provides a calculator of normative data derived from the results of the regression models.
