Abstract(s)
A ansiedade social é uma perturbação caracterizada pelo medo intenso de situações sociais, muitas vezes associada a um viés de interpretação, onde eventos ambíguos são percebidos como ameaçadores, o que pode contribuir para a manutenção e agravamento da ansiedade. No entanto, existem poucos instrumentos adaptados em Portugal para avaliar este viés de forma eficaz. O presente estudo teve como objetivo adaptar e validar a versão portuguesa do Parent Interpretation Bias Measure (PIBM), um
questionário originalmente desenvolvido para medir vieses de interpretação em pais, para ser utilizado em adultos portugueses. Para avaliar as propriedades psicométricas do PIBM, uma amostra de 526 adultos portugueses respondeu ao questionário, que inclui cenários ambíguos relacionados com saúde, interações sociais e segurança. Analisámos a estrutura fatorial do PIBM assim como foi estimada a fiabilidade das medidas proporcionadas por este instrumento (consistência interna e estabilidade temporal).
Fomos também avaliar a possível associação entre o viés de interpretação e os sintomas de ansiedade social reportados pela amostra. Os resultados indicaram que a versão portuguesa do PIBM é uma ferramenta válida e fiável para medir vieses de interpretação na população adulta. Observámos que os participantes tendem a interpretar situações de saúde e de rejeição social de forma mais negativa. Mulheres e pessoas com maior nível de escolaridade apresentaram níveis mais elevados de viés interpretativo. Estes resultados sugerem que o PIBM pode ser uma ferramenta útil na avaliação de distorções cognitivas em contextos clínicos e de investigação, contribuindo para a compreensão e tratamento da ansiedade social e perturbações relacionadas.
Social anxiety is a disorder characterized by an intense fear of social situations, often associated with an interpretation bias, where ambiguous events are perceived as threatening, which can contribute to the maintenance and exacerbation of anxiety. However, there are few instruments adapted in Portugal to effectively assess this bias. The present study aimed to adapt and validate the portuguese version of the Parent Interpretation Bias Measure (PIBM), a questionnaire originally developed to measure interpretation biases in parents, for use with portuguese adults. To evaluate the psychometric properties of the PIBM, a sample of 526 Portuguese adults responded to the questionnaire, which includes ambiguous scenarios related to health, social interactions, and safety. We analyzed the factorial structure of the PIBM and estimated the reliability of the measures provided by this instrument (internal consistency and temporal stability). We also assessed the possible association between interpretation bias and the social anxiety symptoms reported by the sample. The results indicated that the portuguese version of the PIBM is a valid and reliable tool for measuring interpretation biases in the adult population. We observed that participants tend to interpret health and social rejection situations more negatively. Women and individuals with higher educational levels showed higher levels of interpretative bias. These results suggest that the PIBM can be a useful tool in assessing cognitive distortions in clinical and research settings, contributing to the understanding and treatment of social anxiety and related disorders.
