Versão brasileira da Impact of Event Scale (IES): tradução e adaptação transcultural

Abstract

ResumoIntrodução: A Impact of Event Scale (IES) tem como proposta avaliar o estresse subjetivo relacionado a eventos de vida, não estando focada em uma situação específi ca, mas nas características particulares que envolvem tais eventos. Objetivo: Descrever a tradução e adaptação semântica da IES para o português brasileiro. Método: O processo foi realizado por meio de duas traduções e retrotraduções, elaboradas por quatro avaliadores independentes e sem conhecimento prévio da escala original. A elaboração da versão sintética foi realizada por especialista em saúde mental bilíngue. Procedeu-se a posterior aplicação em grupo experimental para avaliação dos itens. A versão gerada foi enviada para aprovação do autor do instrumento original, obtendo-se resposta positiva. Resultados: Todas as etapas do processo, incluindo traduções, retrotraduções e a versão sintética elaborada, são apresentadas para cada um dos 15 itens do instrumento original. O especialista em saúde mental colaborou para a adequação dos termos utilizados em relação ao construto medido. Através da aplicação experimental, foi possível identifi car potenciais pontos de difi culdade para o entendimento de itens específi cos e realizar ajustes posteriores. Foram obtidos 15 itens em português brasileiro para compor essa versão da escala. Conclusões: A partir da metodologia utilizada, foi possível elaborar a adaptação transcultural da IES para o português brasileiro. Descritores: Psicometria, escalas, transtorno de estresse pós-traumático, transtorno de estresse traumático, estresse psicológico, intervenção na crise. AbstractIntroduction: The aim of the Impact of Event Scale (IES) is to evaluate subjective distress associated with life events. The instrument is not focused on a specifi c situation, but rather on the particular characteristics of such events. Objective: To describe the translation and semantic adaptation of the IES into Brazilian Portuguese. Methods: The process consisted of translations and back-translations performed by four independent examiners without prior knowledge of the original scale. The synthetic version was developed by a mental health specialist with profi ciency in both languages. Subsequently, the adapted scale was applied in an experimental group for evaluation. The new/adapted version was revised and approved by the author of the original instrument. Results: We describe all study phases, including translations, back-translations, and the development of the synthetic version, for each of the 15 items contained in the original instrument. The mental health specialist assisted in adapting the terms employed taking into consideration the construct under investigation in each case. The experimental application allowed to identify potential diffi culties in the understanding of specifi c items and to subsequently adjust these items. Fifteen items were developed in Brazilian Portuguese for this version of the scale. Conclusions:The methodology employed in the present study allowed us to conduct the cross-cultural adaptation of...

Severe Maternal Morbidity: post-traumatic suffering and social support

“…The Impact of Event Scale (IES) consists of 15 items of selfreport, Likert type, which measures the presence of avoidance behavior and intrusive memory after traumatic situations, according to frequency attributes, never, rarely, sometimes and always. It was validated for the Brazilian population and the cut limit of 25 points was adopted (16) . The scale is applied to the general population and in the field of obstetrics, related to the experiences of childbirth (17) , its psychometric properties are satisfactory, and continued use is justified as a measure of avoidance and intrusion processes (18) .…”

“…The Impact of Event Scale (IES), a scale developed by Horowitz et al (16) , presents as proposal the assessment of subjective stress related to life events, not being focused in a specific situation, but in the particular characteristics that involve such events. It is a brief scale, composed of only 15 items, divided into a subset connected to the intrusion (items 1, 4, 5, 6, 10, 11 and 14) and a focused subset of avoidance (items 2, 3, 7, 8, 9, 12, 13 and 15).…”

Construction and validation of the Adult Stressors Inventory (ASI)

“…Two options for evaluation of a broader spectrum of stressful events do exist. The Impact of Event Scale has been translated and adapted for Brazil 54 and a stressful life event reporting questionnaire was developed for the Pró-Saúde study, 31 but neither of these cover a wide spectrum of stressful areas of life, unlike the ASI. Finally, the most widely used instrument in Brazil for stress assessment, the ISSL -Adult Stress Symptoms Inventory, 25 is an adequate instrument for identifying stress, but it does not enable identification of the stressors causing stress.…”

Adjustment disorders in the postpartum resulting from childbirth: a descriptive and exploratory study

“…The IES, already translated and validated in Brazil (9) , consists of 15 items that measure, according to attributes of frequency, the presence of intrusive and avoidant symptoms after the occurrence of traumatic situations that, in the case of this study, occurred or were experienced during childbirth. On this scale, women reported Likert-style how they were feeling on each of the issues raised, according to four attributes of frequency:…”
