Delírios Persecutórios: uma Descrição das Teorias e de Estudos Empíricos

 

Sara Sigmaringa Melo 1

 

 

Resumo : Nas últimas duas décadas, a conceptualização das ideias delirantes, em geral, e dos delírios persecutórios, em particular, tem sido alvo de grande contro­vérsia. O presente artigo procura sumarizar e integrar a literatura existente acerca deste tema, começando por descrever brevemente algumas teorias inicialmente propostas para a explicação da paranóia, passando, de seguida, a uma descrição mais detalhada, com base em estudos realizados, das duas mais recentes propostas explicativas para os delírios persecutórios. Estas são a teoria de Trower e Chadwick (1995) e o modelo de Auto­‑Representação Atribucional sugerido por Bentall et al. (2001).

Será necessário que mais investigações sejam conduzidas, tendo em conta o dina­mismo das crenças delirantes, de forma a que seja possível alcançar uma com­preensão mais concertada do desenvolvimento e manutenção da paranóia.

Palavras­‑chave : paranóia, auto­‑estima, cognição­ social e dinamismo.

 

 

Persecutory delusions: a review of theories and evidence based studies

Abstract : The account for delusional beliefs, particularly persecutory beliefs, has been at the centre of much controversy over the last two decades. The present paper summarizes and integrates the existing literature on this topic and starts by briefly describing the first few theories that explained paranoia, moving later to a more detailed evidence based description of the two most recent accounts for paranoia. These are Trower and Chadwick’s theory (1995) and Bentall et al.’s (2001) Attribution­‑Self­‑Representation model.

More studies looking further into the dynamics of delusional beliefs are needed to utterly understand both the development and maintenance of paranoia.

Key­‑words : paranoia, self­‑esteem, social­‑cognition and dynamism.
