Abstract(s)
As perspetivas dos pacientes acerca das suas próprias dificuldades, sintomas e objetivos (relacionados com a sua saúde e outras áreas) são de extrema importância para as intervenções, principalmente tendo em conta modelos recentes baseados na recuperação (no original recovery) das perturbações psicóticas. Cada vez mais os instrumentos de autorresposta têm sido estudados, sendo que vários autores têm defendido a sua validade, fiabilidade e utilidade clínica para pessoas com o diagnóstico de uma perturbação psicótica. Este estudo teve como objetivo rever e analisar de forma crítica os instrumentos de autorresposta existentes para a avaliação da ideação delirante. Quatro instrumentos preencheram os critérios de inclusão: a escala de características dos delírios (Characteristics of Delusions Rating Scale), a escala de avaliação das crenças (Beliefs Rating Scale), o inventário de delírios de Peters (Peters Delusions Inventory) e a escala de convicção nas ideias delirantes (Conviction of Delusional Beliefs Scale). Todas as escalas avaliam as ideias delirantes de uma perspetiva multidimensional e todas apresentam propriedades psicométricas adequadas. No entanto elevada variablidade foi encontrada entre os estudos. O refinar dos estudos psicométricos destes instrumentos (principalmente o investimento em análises de estrutura factorial, fiabilidade e acuidade diagnóstica) e o desenvolvimento de novos instrumentos focados no coping com os delírios são áreas de investigação de interesse para o futuro.
ABSTRACT: According to recent models of recovery in psychosis, the patients’ perspectives about their own difficulties, symptoms and goals (health-related and in other areas) are of major importance in intervention. Self-report measures have been increasingly studied and several authors have pointed out their validity, reliability and clinical utility in people with psychotic-disorders. The present study sought to review and critically analyse the available self-report instruments for assessing delusions. Four instruments met the inclusion criteria: Characteristics of Delusions Rating Scale; Beliefs Rating Scale; Peters Delusions Inventory; and Conviction of Delusional Beliefs Scale. All scales assess delusions in a multidimensional perspective and present adequate psychometric properties, although with high variability within studies. Refining the psychometric studies of the existing instruments (mainly confirmatory factor analysis, reliability and diagnostic accuracy analyses) and developing new instruments focused on coping are future areas of research interest.
