Enquadramento Teórico: A utilização de testes de validade de desempenho é feita de
forma recorrente em processos de avaliação psicológica e neuropsicológica em contexto
de avaliação. Em grupos de litigantes a contextualização dos resultados poderá ser
questionada pois, segundo a literatura, neste grupo de sujeitos a possibilidade de existir
esforço insuficiente na realização das provas, é maior. Isto porque poderão existir
perspetivas de ganho secundário, tais como compensações monetárias, reforma
antecipada ou outro tipo de compensações. Dada a relevância da avaliação do esforço
insuficiente achou-se pertinente estudar na presente amostra de sujeitos, possíveis
alterações do seu perfil neuropsicológico bem como da relação deste com as escalas de
validade do Mini-mult L, F, K, em particular do índice de Gough,.num grupo de sujeitos
envolvidos em situações de litígio e outros indivíduos atendidos numa clínica de
reabilitação de lesão cerebral. Este estudo foi realizado numa amostra Portuguesa.
Metodologia: Este estudo retrospetivo conta com uma amostra de conveniência
constituída por 36 sujeitos com idades compreendidas entre os 23 e os 69 anos que foram
divididos em dois grupos mediante o valor obtido no índice de Gough através do ponto
de corte >12 “simuladores” e “não simuladores”. Foram analisados dados referentes às
funções cognitivas através de várias provas: Escalas de validade de dados psicológicos,
índice de intensidade de sofrimento psíquico, provas neuropsicológicas que avaliam as
funções nervosas superiores e diversos domínios específicos, tais como a memória,
atenção concentrada e sustentada, capacidade de aprendizagem e memória verbal,
coordenação visuo motora, iniciativa e perseveração.
Conclusões: Foram encontradas diferenças significativas entre os grupos nas provas
cognitivas: TMT-B (Erros, Tempo de execução; Rácio B/A) TP (índice de dispersão),
WCST (nº de ensaios administrados, nº de erros, nº de respostas perseverativas e nº de
categorias concluídas). A Memória de dígitos direta é um preditor significativo do índice
de Gough. No grupo de “não simuladores” foram encontradas diferenças significativas
entre os dois momentos de avaliação deste, nas provas que avaliam a capacidade de
abstração do sujeito (MPRc) e a capacidade de aprendizagem (AVLT - Total Learning).
Foi encontrada uma correlação entre o IGS e o índice de Gough.
Theoretical Framework: The use of performance validity tests in psychological and neuropsychological evaluation processes is done on a recurrent basis. In groups of litigants, the contextualization of the results may be questioned, because, according to the literature, in this group of subjects there is a greater chance of insufficient effort in performing the tests. This is likely to happen because there may be prospects of secondary gain, such as monetary compensation, early retirement or other types of compensation. Given the relevance of the evaluation of insufficient effort, it seemed pertinent to study possible changes in the neuropsychological profile of these subjects, as well as its relationship with the scales of validity of the Mini-mult L, F, K, particularly the Gough index, in a group of subjects involved in situations of litigation and in other individuals treated in a brain injury rehabilitation clinic. This study was conducted with a sample of Portuguese subjects. Methodology: This retrospective study uses a convenience sample consisting of 36 subjects, aged between 23 and 69 years, who were divided into two groups by the value obtained in the Gough index through the cutoff point >12 "simulators" and "nonsimulators". Data regarding cognitive functions were analyzed through several tests: psychological data validity scales, psychic suffering intensity index, neuropsychological tests that evaluate superior nervous functions and several specific domains, such as memory, concentrated and sustained attention, learning capacity and verbal memory, visual-motor coordination, initiative and perseverance. Conclusions: Significant differences between groups were found in the cognitive tests: TMT-B (Errors, Time of execution; Ratio B/A) TP (dispersion index), WCST (number of tests administered, number of errors, number of persevering responses and number of concluded categories). MDD is a significant predictor of the Gough index. In the "nonsimulator" group, significant differences were found between the two evaluation moments, in the tests that evaluate the subject's abstraction capacity (MPRc) and learning capacity (AVLT - Total Learning). A correlation between IGS and Gough's index was found.
