Abstract(s)
Ao longo dos anos, surgiu a necessidade de distinguir o conceito de afeto central
de outros conceitos como humor e emoção, considerando os recentes desenvolvimentos
teóricos e empíricos na investigação sobre o afeto central. O afeto central refere-se ao
sentimento mais elementar, conscientemente acessível, que não precisa de ser dirigido a
nada. De forma a suprimir esta carência na população portuguesa pretende-se adoptar
uma nova medida sueca de afeto central que aborde diretamente a valência (V) e a
ativação (A) e que também meça a ativação agradável (AG), a desativação desagradável
(DD), a ativação desagradável (AD) e a desativação agradável (DA). Deste modo, este
estudo teve como objetivo a realização de estudos preliminares para a adaptação
transcultural de um instrumento psicológico, Swedish Core Affect Scale (SCAS) - full
version (Västjfäll et al 2002), de modo a complementar as atuais escalas de medição de
afeto existentes para a população portuguesa.
A amostra foi composta por 97 participantes, com idades compreendidas entre os
18 e os 54 anos. Para a recolha de dados, foram aplicados dois instrumentos de avaliação
do afeto.(i) Escala Sueca de Afeto Central (SCAS), (ii) Escala de Afeto Positivo e
Negativo (PANAS) e um instrumento de rastreio de psicopatologia: (iii) Inventário Breve
de Sintomas (BSI).
Os resultados obtidos com a amostra atual não confirmam a estrutura fatorial
encontrada na população original sueca, o que sugere que a escala deve ser revista, ou
que pelo menos mais dados devem ser obtidos antes de confirmar a estrutura fatorial.
ABSTRACT: Over the years, there has been a need to distinguish the concept of central affect from other concepts such as mood and emotion, considering recent theoretical and empirical developments in research on central affect. Central affect refers to the most elementary, consciously accessible feeling that does not need to be directed towards anything. In order to address this gap in the Portuguese population, it is intended to adopt a new Swedish measure of central affect that directly addresses valence (V) and activation (A) and also measures pleasant activation (PA), unpleasant deactivation (UD), unpleasant activation (UA), and pleasant deactivation (PD). Thus, this study aimed to conduct preliminary studies for the cross-cultural adaptation of a psychological instrument, the Swedish Core Affect Scale (SCAS) - full version (Västjfäll et al. 2002), to complement existing affect measurement scales for the Portuguese population. The sample consisted of 97 participants, aged between 18 and 54 years. For data collection, two affect assessment instruments were applied: (i) Swedish Central Affect Scale (SCAS), (ii) Positive and Negative Affect Schedule (PANAS), and a psychopathology screening instrument: (iii) Brief Symptom Inventory (BSI). The results obtained with the current sample do not confirm the factor structure found in the original Swedish population, suggesting that the scale should be revised, or at least more data should be obtained before confirming the factor structure.
