Enquadramento: As chamadas experiências do tipo psicóticas não existem
apenas entre as populações clínicas, mas podem vir a surgir também entre a população
num geral (Fonseca-Pedrero et.al, 2012).
A CAPE – 42 é um instrumento de autorrelato popular em avaliar a tendência para
a psicose, sobretudo, das experiências do tipo psicóticas, composta por 42 perguntas
representadas através das três dimensões principais de sintomas, (e.g, dimensão positiva,
negativa e depressiva), e que objetivam avaliar a frequência na ocorrência e do incômodo
causado por tais experiências ao longo da vida.
O recurso de validação da CAPE-42 tem apontado resultados num geral
satisfatórios, apesar de algumas limitações também serem observadas (e.g, da dificuldade
em diferenciar determinados itens para as três dimensões conforme a organização original
proposta por seus criadores, e em como determinadas perguntas deste instrumento, são
sensíveis pela tradução realizada e relacionam-se com questões culturais, interferindo
assim nos resultados obtidos).
O presente trabalho teve como principal objetivo, a realização da validação
preliminar do questionário de autorrelato CAPE-42 (Community Assessment of Psychic
Experiencies – Escala de avaliação das experiências psíquicas na comunidade) em uma
amostra composta de estudantes universitários portugueses da Universidade do Algarve.
Participaram neste estudo 186 pessoas (72% sexo feminino; 28% sexo masculino),
com idades entre os 18 aos 21 anos (M= 19,3; DP= 1,01).
Foi realizada uma Análise Fatorial Exploratória (AFE), onde foi analisado as
propriedades psicométricas do instrumento através do estudo da validade do constructo,
da fiabilidade/consistência interna dos itens e da validade convergente. O resultado obtido
deu-se através de uma solução com três fatores (positiva, negativa e depressiva) para a
escala, assim como foi encontrado em outros estudos (Brenner et. al 2007, Daneluzzo et.
al 2008, Fonseca-Pedrero et. al 2012, Schlier et. al 2015, Mark & Toulopoulou 2017,
Ragazzi et. al 2020, Pouennak et. al 2021). A consistência interna representada através
do alpha de Cronbach do total da escala foi no valor de (0,91) e para as três dimensões
da escala da CAPE-42, foi de respetivamente: dimensão depressiva (0,92), dimensão
positiva (0,81) e por fim, dimensão negativa (0,68). Portanto num geral, os resultados
demonstraram ser bom e excelente, excento apenas para a dimensão negativa que obteve um valor ligeiramente abaixo do mínimo recomendado, embora a baixa quantidade de
itens seja a principal hipótese para este resultado. O instrumento ainda provou obter uma
boa validade convergente.
Objetivo: Realizar a validação preliminar portuguesa do instrumento de autorrelato
CAPE-42 em uma amostra composta de estudantes universitários portugueses.
Método: Foi realizado um procedimento de Análise Descritiva e Fatorial Exploratória
(AFE) do instrumento (validade do constructo, confiabilidade/consistência interna dos
itens e da validade convergente) através do recurso de Análise Estatística dos Dados com
o uso do programa IBM SPSS 26 - Statistical Analysis Software.
Resultados: Os resultados encontrados neste estudo preliminar, sugerem que o
instrumento de autorrelato da CAPE – 42, apesar de ter alguns constrangimentos acerca
da disposição de seus itens para cada dimensão que compõe esta escala, se apresenta num
geral, como uma medida confiável para avaliar as experiências do tipo psicóticas na
população geral.
Conclusões: Concluiu-se com este trabalho preliminar que o instrumento de autorrelato
da CAPE-42 para a versão portuguesa, possui apropriadas propriedades psicométricas e
recomenda-se o seu uso na deteção de experiencias do tipo psicóticas na população geral.
Background: Psychotic - like experiences do not only exist amongst clinical population, but they may also can be found in general population (Fonseca-Pedrero et.al, 2012). The CAPE – 42 it´s a popular self - report scale instrument to assess psychosis proneness, mainly over psychotic – like experiences with a total of 42 questions based through three main symptom dimensions, (e.g, positive dimension, negative and depressive), with its objective to evaluate both the frequency of occurrence and distress caused from those experiences along life side. The validity of CAPE-42 results outlined overall good reportings, despite some limitations have been observed (e.g, the difficulty issued towards differentiating some items between the three main symptom dimensions, as regarded by the proposed model from its creators, and some specific questions have been signed as sensitive related to translation procedure and over cultural subject). The main objective of this dissertation paper it is to do a preliminary validation of the self - report scale CAPE – 42 (Community Assessment of Psychic Experiences) over a Portuguese undergraduate students’ sample from University of Algarve. Our sample size has accounted with the total of 186 people (72% feminine sex; 28% masculine sex), between 18 and 21 years old (M=19,3; DP= 1,01). An Exploratory Factor Analysis (EFA) it was undertake, and the psychometric properties were analyzed due the study of its construct validity, reliability/internal items consistency and convergent validity. Our results reported a three-factor solution on total scale (positive, negative and depressive), similar to previous studies (Brenner et. al 2007, Daneluzzo et. al 2008, Fonseca-Pedrero et. al 2012, Schlier et. al 2015, Mark & Toulopoulou 2017, Ragazzi et. al 2020, Pouennak et. al 2021). The internal consistency of CAPE – 42 which it is represented by Cronbach´s alpha for the total of the scale had a result of (0,91) and for the three-dimension scale, depressive dimension (0,92), positive dimension (0,81) and negative dimension (0,68) outlined respectively these results. Therefore, overall, the results were considered good and excellent related to their internal consistency index, except it for the negative dimension which obtained a slightly below recommended minimum value, although the paucity in the total of the items, it´s the main hypothesis about getting this result. The instrument also outlined good convergent validity. Objective: To do a preliminary validation of the self - report instrument CAPE-42 over a Portuguese undergraduate student’s sample. Method: It was performed a descriptive analysis and exploratory factorial analysis (EFA) of this self - report instrument (construct validity, reliability/internal items consistency and convergent validity) using the Statistical Analysis of the data from IBM SPSS 26 - Statistical Analysis Software Program. Results: The outlined results in this preliminary study, suggests that the CAPE-42, despite some irregularities about the disposition from its items for each dimension compounded on this scale, it has presented, overall, as a reliable measure to assess the psychotic – like experiences in the general population. Conclusions: In conclusion, this preliminary study outlined the Portuguese version of CAPE -42 self- report scale instrument as having good psychometric properties and we recommend its use to assess psychotic - like experiences in the general population.
