Resumo(s)
Os eventos traumáticos podem ocorrer em qualquer indivíduo e têm o potencial de desencadear a perturbação de stress pós-traumático (PSPT), a qual, por sua vez, pode influenciar a reatividade do sistema nervoso autónomo (SNA). O presente estudo teve como objetivo investigar a relação entre eventos traumáticos, PSPT e reatividade do SNA. Trata-se de um estudo quantitativo e transversal, cuja amostra é constituída por 120 participantes: 90 indivíduos da população geral e 30 da população clínica, com idades entre 19 e 77 anos. A recolha de dados foi efetuada através de quatro instrumentos: questionário sociodemográfico, Life Events Checklist for DSM-5 (LEC-5), Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) e Body Perception Questionnaire (BPQ). Os resultados indicaram que mulheres com histórico de eventos traumáticos apresentaram níveis mais elevados de sintomas de PSPT, sem diferenças significativas na reatividade do SNA em comparação com mulheres sem histórico de trauma. Por outro lado, sobreviventes de violência por parceiro íntimo exibiram níveis mais elevados de sintomas de PSPT e maior reatividade do SNA. A análise correlacional evidenciou que maior exposição a eventos traumáticos se associa a níveis mais elevados de sintomatologia de PSPT e, de forma moderada, a maior reatividade autonómica. A regressão múltipla revelou que os sintomas de PSPT constituem um preditor significativo da reatividade do SNA, enquanto os eventos traumáticos isoladamente não apresentaram efeito preditivo. Estes resultados sugerem que a avaliação e intervenção precoce em sintomas de PSPT podem ser fundamentais para modular a reatividade do sistema nervoso autónomo, destacando a importância de estratégias terapêuticas direcionadas para sobreviventes de trauma, especialmente em contextos de violência por parceiro íntimo.
Traumatic events can occur in any individual and have the potential to trigger post traumatic stress disorder (PTSD), which, in turn, can influence the reactivity of the autonomic nervous system (ANS). The present study aimed to investigate the relationship between traumatic events, PTSD, and ANS reactivity. This is a quantitative, cross-sectional study with a sample of 120 participants: 90 individuals from the general population and 30 from the clinical population, aged between 19 and 77 years. Data collection was performed using four instruments: a sociodemographic questionnaire, the Life Events Checklist for DSM-5 (LEC-5), the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), and the Body Perception Questionnaire (BPQ). The results indicated that women with a history of traumatic events had higher levels of PTSD symptoms, with no significant differences in ANS reactivity compared to women without a history of trauma. On the other hand, survivors of intimate partner violence exhibited higher levels of PTSD symptoms and greater ANS reactivity. Correlational analysis showed that greater exposure to traumatic events is associated with higher levels of PTSD symptoms and, to a moderate extent, greater autonomic reactivity. Multiple regression revealed that PTSD symptoms are a significant predictor of ANS reactivity, while traumatic events alone had no predictive effect. These results suggest that early assessment and intervention in PTSD symptoms may be fundamental to modulating autonomic nervous system reactivity, highlighting the importance of therapeutic strategies targeted at trauma survivors, especially in contexts of intimate partner violence.
