Resumo
A presente investigação teve como objetivo o estudo psicométrico de dois instrumentos breves bem estabelecidos de rastreio cognitivo: o Mini-Mental State Examination e o Short Test, através das curvas ROC para determinar a capacidade discriminativa do MMSE na deteção do declínio cognitivo em indivíduos com perturbação do uso de substâncias, bem como, das correlações entre os sub-testes das duas provas e da influência de características sociodemográficas nas pontuações totais de cada um dos instrumentos. A amostra baseou-se em arquivos de dados, sendo selecionada uma amostra clínica com pacientes com perturbação por uso de substâncias e uma amostra da população geral. A amostra total foi constituída por 797 pessoas de ambos os sexos, com 89 pessoas do grupo AUD, 115 pessoas do grupo SUD e 593 da população geral. Os resultados indicam que ambos os testes são sensíveis a variáveis sociodemográficas tais como a idade e a escolaridade e o MMSE que nos permitiu a análise da amostra clínica aponta ter uma capacidade discriminativa superior para indivíduos consumidores de substâncias a longo prazo.
The aim of the present investigation was the psychometric study of two well-established brief cognitive screening instruments: the Mini-Mental State Examination and the Short Test, using ROC curves to determine the MMSE discriminative ability to detect cognitive decline in individuals with Substance Use Disorder as well as the correlations between the subtestes of the two instruments and the influence of sociodemographic characteristics on the total score of each instrument. The sample was based on data files and it was selected a clinical sample constituted with patients with substance use disorder and a sample of the general population. It was composed by 797 subjects of both genders, with 89 people from the AUD group, 115 people from SUD group and 593 from the general population. The results showed that both tests are sensitive to some sociodemographic variables such as age and education. The MMSE, which allowed us to analyse the clinical sample points to have superior discriminative capacity for long term substance use.
