Abstract

The prevalence of anxiety and its associated factors in Ethiopians necessitates availability of a valid questionnaire tool to screen for this disorder. Therefore, this study aimed to assess the factor structure, its stability, and psychometric measures of the Generalized Anxiety Disorder-7 Scale GAD-7) in Ethiopian university students. A cross-sectional study with random sampling was carried out in students (n = 354, age = 21.79 ± 4.49) attending Mizan-Tepi University, Ethiopia. The GAD-7, the Perceived Stress Scale (PSS), and a sociodemographic questionnaire were completed by participants. The unidimensional model of the GAD-7 showed configural, metric, scalar, and strict invariance among gender groups. The Cronbach's alpha (0.77), item-total score correlations (r = .51-.72, p < .01), and inter-item correlations (all significant, p < .05) indicated adequate internal consistency. GAD-7 scale scores correlated significantly with the PSS, suggesting desired convergent validity. The GAD-7 has good psychometric validity with Ethiopian university students.

埃塞俄比亚大学生广泛性焦虑障碍-7量表的心理测量特征。

埃塞俄比亚人普遍存在焦虑症及其相关因素，因此有必要提供一种有效的问卷工具来筛查这种疾病。因此，本研究旨在评估埃塞俄比亚大学生广泛性焦虑障碍-7量表(GAD-7)的因素结构、稳定性和心理测量方法。采用横断面随机抽样方法对埃塞俄比亚Mizan-Tepi大学学生(n = 354，年龄= 21.79±4.49)进行研究。参与者完成GAD-7、感知压力量表(PSS)和社会人口学问卷。GAD-7的一维模型在性别群体中表现出构型、度量、标量和严格不变性。Cronbach's alpha(0.77)，项目总分相关性(r = 0.51)。72, p < 0.01)，项目间相关性(均显著，p < 0.05)表明足够的内部一致性。GAD-7量表得分与PSS显著相关，提示有良好的收敛效度。GAD-7在埃塞俄比亚大学生中具有良好的心理效度。
