Resumo(s)
A Perturbação do Stress Pós-Traumático (PTSD) é uma perturbação mental
grave, desenvolvida após a exposição a eventos traumáticos, como violência, situações
de guerra e/ou desastres naturais. O diagnóstico precoce é essencial para mitigar as
consequências graves da patologia, como o isolamento social, desemprego, abuso de
substâncias e até comportamentos suicidas. Em Angola e Portugal, a prevalência de
traumas ligados à Guerra Colonial e à Guerra Civil é significativa, reforçando a
necessidade de ferramentas eficazes para identificar e posteriormente tratar a
patologia. O objetivo deste estudo é adaptar, validar e comparar as propriedades
psicométricas da National Stressful Events Survey PTSD Short Scale (NSESSS-PTSD)
original tanto para a população portuguesa, como para a população angolana,
explorando as diferenças deste instrumento nos dois contextos geográficos.
O estudo foi conduzido em Portugal e Angola, com uma amostra total de 287
participantes, subdivididos em dois grupos: grupo A (Portugal): n= 158 e grupo B
(Angola): n=129, com idade mínima de 18 anos. Os métodos utilizados foram o
Questionário sociodemográfico que inquiriu inicialmente os participantes acerca de
várias características sociodemográficas, o NSESSS-PTSD, que pretendeu medir a
gravidade dos sintomas de PTSD e o Posttraumatic Checklist for DSM-5 (PCL5) que é
composto por 20 itens e que avalia sintomas de PTSD com base nos critérios do DSM-5.
Os resultados revelaram que a versão adaptada da NSESSS-PTSD é um
instrumento fiável, válido e culturalmente sensível para a avaliação de sintomas de
PTSD em populações lusófonas, contribuindo para a investigação transcultural e para a
prática clínica em Portugal e Angola. Torna-se necessário dar continuidade a estes
estudos com amostras mais representativas de ambos os países.
The Post-Traumatic Stress Disorder (PTSD) is a severe mental disorder that develops following exposure to traumatic events such as violence, war situations, and/or natural disasters. Early diagnosis is essential to mitigate the serious consequences of the condition, such as social isolation, unemployment, substance abuse, and even suicidal behaviors. In Angola and Portugal, the prevalence of trauma related to the Colonial War and the Civil War is significant, reinforcing the need for effective tools to identify and subsequently treat the disorder. The aim of this study is to adapt, validate, and compare the psychometric properties of the original National Stressful Events Survey PTSD Short Scale (NSESSS-PTSD) for both the Portuguese and Angolan populations, exploring differences in this instrument across the two geographical contexts. The study was conducted in Portugal and Angola, with a total sample of 287 participants, divided into two groups: Group A (Portugal): n = 158 and Group B (Angola): n = 129, with a minimum age of 18 years. The instruments used were a Sociodemographic Questionnaire, which collected various sociodemographic characteristics; the NSESSS-PTSD, designed to assess the severity of PTSD symptoms; and the Posttraumatic Checklist for DSM-5 (PCL-5), composed of 20 items that evaluate PTSD symptoms based on DSM-5 criteria. The results revealed that the adapted version of the NSESSS-PTSD is a reliable, valid, and culturally sensitive instrument for assessing PTSD symptoms in Portuguesespeaking populations, contributing to cross-cultural research and clinical practice in Portugal and Angola. Further studies with more representative samples from both countries are needed to consolidate these findings.
