          Abstract

          Este estudo objetivou testar a dimensionalidade da Escala de Necessidade de Cognição (NCS-18), controlando o efeito dos itens negativos. Participaram 215 estudantes universitários de João Pessoa (PB), com média de idade de 20 anos (DP = 3,79), os quais responderam a NCS-18 e questões demográficas. Testaram-se três modelos: M1 (modelo unifatorial convencional), M2 (modelo bifatorial, com itens positivos e negativos saturando em fatores separados) e M3 (modelo unifatorial, sendo controlado o efeito de itens negativos). Os resultados mostraram que os modelos M2 e M3 apresentaram melhores indicadores de ajuste quando comparados ao M1; porém, o M3 foi também superior ao M2. Concluiu-se, portanto, que a NCS-18 é mais bem representada por meio de uma estrutura unifatorial, especialmente quando é controlado o efeito de itens negativos.

          This study aimed at testing the dimensionality of the Need for Cognition Scale (NCS-18), controlling the effect of negative items. Participants were 215 undergraduate students from João Pessoa (PB) with mean age of 20 years (SD = 3.79). They answered the NCS-18 and demographic questions. Three models were tested: M1 (conventional one-factor model), M2 (two-factor, with positive and negative items loading in separate factors), and M3 (one-factor model, controlling for the effect of negative items). Results showed that M2 and M3 models had better fit indexes compared to M1. Nevertheless, M3 also had better fit indexes than M2. In conclusion, evidence that the NCS-18 is more adequately represented by one-factor model was observed, especially when the effect of negative items is controlled.
