Development and content validity of the Brazilian Brief Neuropsychological Assessment Battery Neupsilin.

Abstract

This paper aims to present the process of construction and content validity of the Brazilian Brief Neuropsychological Assessment Battery Neupsilin, developed to briefly examine the neuropsychological profile of both clinical and healthy populations. It evaluates time and spatial orientation, attention, perception, memory, arithmetic abilities, language, praxia and executive functions (problem solving and verbal fluency). The process of construction was based on psychometric procedures: 1) construction of a preliminary version of the instrument, founded on clinical and research experience of the three specialists, as well as on research on the literature and on already available instruments; 2) blind judges' analyses: a) an analysis of the importance of the inclusion of each subtest considering the assessed construct and the instrument's goal, b) an analysis of the adequacy of each item regarding the construct; 3) reformulation of the instrument; 4) semantic analysis of the items and brainstorming; 5) final analysis done by three specialist judges; 6) pilot study and final version, and 7) content validity. Modifications were done in each stage of the development of the Neupsilin. It demonstrated adequate content validity, with advantages and limitations.

Space protection dynamics in basketball: Validation and application to the evaluation of offense-defense patterns

“…The validation of the SPDs followed a seven step approach, according to the guidelines presented by Fonseca, Salles, and Parente (2008): i) construction of a preliminary version of the instrument, founded on empirical experience of the researchers involved with the work, opinion of high-level coaches, and literature research; ii) blind judges' analyses: an analysis of the adequacy of the inclusion of each element in the instrument, considering the assessed construct and the instrument's goal; iii) reformulation of the instrument; iv) semantic analysis of the items; v) analysis of the instrument (i.e., three blinded specialists, other than those of step i, judge the instrument); vi) pilot study and final version, and vii) application. The seven steps to the validation of the SPDs are explained below:…”

Depressive signs and cognitive performance in patients with a right hemisphere stroke

“…The validity of the GDS-15 for other age groups, like younger and adults, has already been reported in the literature (19) . The cognitive abilities were assessed by the Instrument of Brief Neuropsychological Assessment (NEUPSLIN) (20) , which is an instrument with a brief administration time aiming at verifying preserved and impaired abilities in components of eight different cognitive functions, giving support to a neuropsychological diagnosis. It includes the following tasks, all of them administered in this study: Concentrated attention (inverted counting and digit repetition); Visual perception (verification of similarities and differences of lines, hemineglect, faces perception and recognition); Working memory (ascendant ordering of digits and auditory span of words in sentences); Episodic-semantic verbal memory (delayed and immediate recall and word list recognition); Long-term semantic memory; Short-term visual memory (figures); Prospective memory; Arithmetic abilities (simple addition, subtraction, multiplication and division calculation); Oral language (objects and figures' naming, words and non-words' repetition, automatic language, inference comprehension and processing); Written language (reading aloud of words and non-words, written comprehension, spontaneous writing, copying, words and non-words dictation); Apraxia (ideomotor, constructive and reflexive), and Executive functions (simple problems' resolution and orthographic verbal fluency -letter F).…”

Aplicação do teste M1-Alpha em sujeitos normais com baixa escolaridade: estudo piloto

“…In Brazil, a research group is adapting the Montreal-Toulouse aphasia assessment protocol to Brazilian Portuguese (7). However, it is known that these studies, if done rigorously, take many years to complete since sociodemographic, psychometric and neuropsychological variables must be explored (8)(9)(10) . The M1-Alpha test is an important instrument for diagnosing aphasia through brief procedures such as screening in hospital settings.…”
