Resumo(s)
O presente estudo pretendeu compreender a influência do traço de personalidade Neuroticismo no padrão de sincronia psicofisiológica entre parceiros de uma díade romântica e, consequentemente, na satisfação com a sua relação conjugal. Para tal, registou-se a atividade cardíaca de sete casais heterossexuais (N=14 participantes) durante uma tarefa de linha de base (descrição de objetos neutros) e durante tarefas de interação verbal focadas em aspetos negativos ou positivos do seu parceiro ou da sua relação. Previamente, cada participante tinha preenchido individualmente dois questionários, o NEO-FFI e o R-DAS, os quais permitiram avaliar o seu traço de personalidade Neuroticismo e o nível de satisfação conjugal, respetivamente. Recorrendo aos registos da atividade cardíaca durante as interações verbais dos dois elementos de um casal, calcularam-se os índices de sincronia psicofisiológica para cada díade. À semelhança de estudos anteriores, os níveis de sincronia fisiológica foram mais elevados durante as interações negativas do que durante as positivas, embora estas diferenças não alcançassem significância estatística. Adicionalmente, não se verificaram associações significativas entre os níveis de sincronia fisiológica e os valores de Neuroticismo e de satisfação conjugal do casal. São discutidas as implicações, limitações e possíveis direções futuras resultantes deste estudo.
The present study aimed to understand the influence of the personality trait Neuroticism in the pattern of psychophysiological synchrony between partners of a romantic dyad and, accordingly, in their satisfaction with their conjugal relationship. To that end, we recorded the heart rate activity of seven heterosexual couples (N=14 participants) during a baseline task (description of neutral objects) and during verbal interaction tasks focused on negative or positive aspects of their partner or relationship. Prior to that, each participant had completed two questionnaires, the NEO-FFI and the R-DAS, which allowed the assessment of their Neuroticism personality trait and their dyadic satisfaction, respectively. Based on the recordings of heart rate activity during the verbal interactions of the two elements of a couple, psychophysiological synchrony indices of each couple were calculated. Similar to previous studies, it was found that psychophysiological synchrony levels were higher during negative interactions in comparison with positive ones, although these differences did not reach statistical significance. Moreover, no statistically significant association was found between psychophysiological synchrony levels and Neuroticism and dyadic satisfaction scores. The scope, limitations and possible future directions deriving from this study are discussed.
