Abstract(s)
A Movie for the Assessment of Social Cognition (MASC; Dziobek, 2006) tem sido considerada uma medida para avaliar a mentalização com forte utilidade científica. Estudos anteriores têm encontrado boas propriedades psicométricas, considerando-a uma medida ecologicamente válida da cognição social. Do nosso conhecimento, em portugal, não existe nenhuma adaptação da MASC nem existem medidas alternativas para avaliar o construto de mentalização. Neste contexto, tivemos como principal objetivo analisar as propriedades psicométricas da versão portuguesa da MASC. Para o efeito, procedeu-se, num primeiro momento, à tradução da MASC, tendo-se procedido à avaliação da sua fiabilidade e validade (recorrendo à escala Mentalization Questionnaire; Hausberg et al., 2012), numa amostra de 78 universitários portugueses com ausência de doenças psiquiátricas e neurológicas.
Foram obtidas pontuações médias de acerto semelhantes às encontradas em estudos anteriores assim como indicadores satisfatórios de estabilidade temporal. Foi registada, ainda que de forma modesta, uma correlação positiva com a medida de autorrelato de mentalização. Ao contrário do esperado, o indicador de consistência interna da MASC-PT não foi satisfatório (α = .55) e a estrutura fatorial extraída não foi passível de interpretação clara. Estes resultados levantam-nos questões acerca da validade desta adaptação portuguesa que serão discutidos neste trabalho. Mais estudos deverão ser conduzidos com o intuito de investigar a consistência interna da medida e estrutura fatorial em outras amostras de participantes saudáveis e em estudos diferenciais com participantes clínicos.
The Movie for the Assessment of Social Cognition (MASC; Dziobek, 2006) has been considered a measure to assess mentalization with strong scientific utility. Previous studies have found good psychometric properties, considering it an ecologically valid measure of social cognition. To our knowledge, in portugal, there is no adaptation of the MASC nor are there any alternative measures to assess the mentalization construct. Therefore, our main objective was to analyze the psychometric properties of the portuguese version of the MASC. For this purpose, we first translated the MASC and assessed its reliability and validity (using the Mentalization Questionnaire; Hausberg et al., 2012) in a sample of 78 portuguese university students without psychiatric and neurological disorders. The mean scores and the indicators of temporal stability obtained were similar to those found in previous studies. Also, a positive correlation was observed, albeit modestly, with the self-report measure of mentalization. Contrary to expectations, the internal consistency of the MASC-PT was not satisfactory (α = .55) and the extracted factor structure was not amenable to clear interpretation. These results raise questions about the validity of this portuguese adaptation that will be discussed in this paper. Further studies should be conducted in order to investigate the internal consistency and factor structure of the measure in other samples of healthy participants and in differential studies with clinical participants.
