Exposure to violence can have strong detrimental effects on adolescents, including long-term negative consequences for development, adjustment, and functionality. This study tests the factorial structure, psychometric properties, and construct validity of a Portuguese version of the Exposure to Violence Scale (EVS); a measure of adolescents’ direct and indirect exposure to violence at school, in their community, at home, and on TV. The study sample comprised 306 Portuguese adolescents, 53.9% of whom were boys (M_age = 13 years, SD = 1.6), from the 6th to 10th grades. These adolescents completed the EVS, a measure of positive and negative affect, and a measure of perceived quality of life. We used confirmatory factor analysis to test structural validity. This analysis indicated that a seven correlated factors model fit well with the data. Cronbach’s alpha values indicated that the sub-scales were reliable. T-tests indicated that older adolescents typically reported greater exposure to violence than younger adolescents, and that boys experienced more direct violence at school and home, and indirect violence in the community, than girls did. Finally, positive correlations with negative affect, and negative correlations with positive affect and well-being, offered evidence of convergent validity. The EVS for Portuguese adolescents has adequate psychometric properties for use as a brief screening tool for assessing the various forms and contexts of exposure to violence in adolescents. Having this validated instrument for use in Portugal has important implications for teachers, health and social professionals, and researchers.

遭受暴力侵害会对青少年产生严重的不利影响，包括对发展，适应和功能的长期负面影响。这项研究测试了葡萄牙语版本的暴力暴露量表（EVS）的阶乘结构，心理计量特性和建构效度；衡量青少年在学校，社区，家庭和电视中直接和间接遭受暴力侵害的程度。该研究样本包括306名葡萄牙青少年，其中53.9％是男孩（M_年龄 = 13岁，SD = 1.6），从6年级到10年级。这些青少年完成了EVS，衡量正面和负面影响以及衡量所感知的生活质量。我们使用验证性因素分析来测试结构有效性。该分析表明，七个相关因素模型与数据非常吻合。克朗巴赫（Cronbach）的alpha值表明该子量表是可靠的。Ť-测试表明，年长的青少年通常比年青的青少年遭受暴力的机会更大，而男孩比女孩在学校和家庭中遭受的直接暴力和在社区中的间接暴力更为严重。最后，具有负面影响的正相关和具有正面影响和幸福的负相关提供了收敛效度的证据。葡萄牙青少年的EVS具有足够的心理计量学特性，可以用作评估青少年遭受暴力侵害的各种形式和背景的简短筛查工具。拥有在葡萄牙使用的经过验证的仪器，对教师，卫生和社会专业人员以及研究人员具有重要意义。
