Abstract(s)
Introdução: A presente investigação tem como objetivo avaliar a manifestação das variáveis:
stress percebido, alexitimia, ansiedade e depressão em pacientes com doenças autoimunes e
avaliar se existe um possível efeito mediador da alexitimia na relação entre o stress percebido
e a ansiedade e a depressão. Método: Este estudo conta com 347 participantes (Midade =
39,60; DP = 12,38) e a amostra é não probabilística e por conveniência. Procedeu-se à
aplicação de um questionário online, constituído pela Escala de Ansiedade e Depressão
Hospitalar, a Escala de Stress Percebido, e a Escala de Alexitimia de Toronto. Resultados:
Verificou-se que as variáveis em estudo se encontram correlacionadas positiva e
significativamente entre si. Adicionalmente, tanto o stress percebido como a alexitimia têm
efeitos diretos, totais e indiretos significativos na depressão e na ansiedade. Observou-se que
o stress percebido é um preditor mais elevado de ansiedade (βalexitimia = 0,22; p ≤ 0,001; βstress
percebido = 0,62; p ≤ 0,001) e depressão (βalexitimia = 0,21; p ≤ 0,001; βstress percebido = 0,56; p ≤
0,001), do que a alexitimia. Discussão: Este estudo permite elucidar sobre um mecanismo de
gestão de stress percebido dos pacientes com doenças autoimunes, bem como o efeito de
mediação parcial do stress percebido no aumento do impacto da alexitimia na ansiedade e na
depressão.
Introduction: The present research aims to evaluate the manifestation of the variables perceived stress, alexithymia, anxiety and depression in patients with autoimmune diseases and to assess whether there is a possible mediating effect of alexithymia in the relationship between perceived stress and anxiety and depression. Method: This study counts with 347 participants (Mage = 39,60; SD = 12,38), and the sample is not probabilistic and by convenience. An online questionnaire was applied, consisting of the Hospital Anxiety and Depression Scale, the Perceived Stress Scale, and the Toronto Alexithymia Scale. Results: It was found that the variables under study are positively and significantly correlated with each other. Additionally, both perceived stress and alexithymia have significant direct, total and indirect effects on depression and anxiety. It was observed that perceived stress is a higher predictor of anxiety (βalexithymia = 0.22, p ≤ 0.001; βperceived stress = 0.62, p ≤ 0.001) and depression (βalexithymia = 0.21, p ≤ 0.001; βperceived stress = 0.56, p ≤ 0.001), than alexithymia. Discussion: This study provides insight into a perceived stress management mechanism of patients with autoimmune diseases, as well as the partial mediating effect of perceived stress on the relationship between alexithymia and anxiety and depression.
