O crescente desenvolvimento de instrumentos destinados à avaliação das
Perturbações da Personalidade tem levado ao desenvolvimento de novas abordagens
diagnósticas, nomeadamente através de provas projetivas como seja o T.A.T. (Thematic
Apperception Test). Com o presente estudo pretendeu-se avaliar a validade e fiabilidade do
sistema de cotações do T.A.T. pelo S.C.O.R.S. (Social Cognitions and Object Relations Scale),
como um instrumento de classificação diagnóstica das Perturbações da Personalidade, que
se baseia em dimensões relevantes das teorias psicanalíticas, nomeadamente nas
respeitantes aos modelos de relações de objeto. Participaram 40 sujeitos divididos em dois
grupos, sendo 20 utentes do Hospital de Dia do Serviço de Psiquiatria do Centro
Hospitalar Lisboa-Norte, Hospital de Santa Maria e 20 sujeitos normativos. Como
instrumentos foram utilizadas cinco pranchas do T.A.T cujas narrativas foram cotadas com
o sistema S.C.O.R.S. por três cotadores independentes e o inventário de
autopreenchimento M.C.M.I.-III. Estes sistemas permitem avaliar de forma independente
vários níveis de funcionamento da personalidade. Verificaram-se diferenças
estatisticamente significativas entre os dois grupos (Grupo Clínico e Grupo Normativo),
tendo os resultados sido favoráveis ao Grupo Normativo em ambos os instrumentos.
Verificaram-se correlações altamente significativas entre os valores obtidos em cada uma
das escalas do S.C.O.R.S. e os cartões do T.A.T., bem como entre estes dois e alguns
Padrões de Personalidade avaliados pelo M.C.M.I.-III. Concluiu-se, assim, que a
combinação da informação obtida através de ambos os instrumentos potencia o acesso à
estrutura e organização psicológicas inerentes a cada Padrão da Personalidade, mais do que
através de cada um separadamente.
ABSTRACT______The increasing development of instruments aimed to evaluate Personality Disorders has led to the development of new diagnostic approaches, namely through projective measures such as the T.A.T. (Thematic Apperception Test). The aim of the present study was to assess the validity of the T.A.T.'s scoring system through S.C.O.R.S. (Social Cognitions and Object Relations Scale), as an instrument of diagnostic classification of Personality Disorders, which is based on relevant dimensions of the psychoanalytic theories, namely those relative to the object relations' models. Forty subjects split into group participated, being twenty of them patients of the Day Hospital of the Psychiatric Service of the Centro Hospitalar Lisboa-Norte, Hospital de Santa Maria and twenty normative subjects. As instruments, five T.A.T. cards whose narratives were scored with the S.C.O.R.S. system by three independent scorers and the self-report inventory M.C.M.I.- III. These systems allow to individually discriminate several levels of personality functioning. Statistically significant differences were found between the two groups (Clinical Group and Normative Group), being the results favorable to the Normative Group in both instruments. Highly significant correlations were found between the values obtained in each S.C.O.R.S.' scale and T.A.T. cards, as well as between the last two and some Personality Patterns assessed by the M.C.M.I.-III. Therefore, it can be concluded that the combination of the information obtained through both instruments maximizes the access to the psychological structure and organization inherent to each Personality Pattern, even more than through each one separately.
