■大学生的焦虑会导致学习成绩差甚至辍学。成人表现焦虑量表(AMAS-C)是一种经过验证的方法,旨在评估大学生的焦虑水平和性质。
■这项研究的目的是为AMAS-C提供基于互联网的替代方案,以自动识别和预测年轻大学生的焦虑。两种焦虑预测方法,一个基于面部情感识别,另一个基于文本情感识别,使用AMAS-C测试焦虑进行描述和验证,谎言和完全焦虑作为地面实况数据。
■第一种方法分析面部表情,确定六种基本情绪(愤怒,厌恶,恐惧,幸福,悲伤,惊讶)和中立的表达,当学生完成技术技能测试时。第二种方法检查分类为积极的帖子中的情绪,社交网络Facebook上的学生个人资料中的负面和中立。两种方法都旨在预测焦虑的存在。
■这两种方法在预测焦虑方面都达到了很高的精度,并且被证明在识别与AMAS-C验证工具相关的焦虑障碍方面是有效的。与基于面部分析的预测(84.21%)相比,基于文本分析的预测在预测焦虑方面的精度(86.84%)略有优势。
■开发的应用程序可以帮助教育工作者,心理学家或相关机构在早期阶段确定那些可能因焦虑症而在大学学业失败的学生。
UNASSIGNED: Anxiety in university students can lead to poor academic performance and even dropout. The Adult Manifest Anxiety Scale (AMAS-C) is a validated measure designed to assess the level and nature of anxiety in college students.
UNASSIGNED: The aim of this study is to provide internet-based alternatives to the AMAS-C in the automated identification and prediction of anxiety in young university students. Two anxiety prediction methods, one based on facial emotion recognition and the other on text emotion recognition, are described and validated using the AMAS-C Test Anxiety, Lie and Total Anxiety scales as ground truth data.
UNASSIGNED: The first method analyses facial expressions, identifying the six basic emotions (anger, disgust, fear, happiness, sadness, surprise) and the neutral expression, while the students complete a technical skills test. The second method examines emotions in posts classified as positive, negative and neutral in the students\' profile on the social network Facebook. Both approaches aim to predict the presence of anxiety.
UNASSIGNED: Both methods achieved a high level of precision in predicting anxiety and proved to be effective in identifying anxiety disorders in relation to the AMAS-C validation tool. Text analysis-based prediction showed a slight advantage in terms of precision (86.84 %) in predicting anxiety compared to face analysis-based prediction (84.21 %).
UNASSIGNED: The applications developed can help educators, psychologists or relevant institutions to identify at an early stage those students who are likely to fail academically at university due to an anxiety disorder.
