Various screening tools have been designed and developed to identify individuals with generalized anxiety disorder (GAD). The current study aimed to assess the psychometric validation of the GAD-7 in Saudi university male students.
Healthy university male students (n= 192) participated in this cross-sectional study. All the participants were informed about the study details. Participants were asked to complete the GAD-7, the Sleep Hygiene Index (SHI), Perceived Stress Scale (PSS), and demographic details.
In general, the range of the GAD total score was 0-21. There was no issue of the ceiling or floor effects as only 12.5% of participants reported the minimum score of 0, and none of the participants reported the maximum score of 21. The internal consistency score of the GAD-7 was found to be good (Cronbach's alpha = 0.83). The internal homogeneity between item scores was 0.22-0.57 as indicated by the "Spearman correlation coefficient ()". The total scores and individual item scores of the GAD-7 were statistically associated with the PSS total score (correlation coefficient = 0.21-0.37), and scores of the 8th and 13th item of the SHI (correlation coefficient = 0.17-0.26, and 0.21-0.40, respectively). The exploratory factor and confirmatory factor loadings of the GAD-7 items were ranged from 0.60 to 0.81 and 0.51 to 0.80, respectively.
This study supported the use of the GAD-7 to assess the anxiety level among Saudi university students.
已设计并开发了各种筛查工具来识别广泛性焦虑症（GAD）患者。本研究旨在评估GAD - 7在沙特大学生男性中的心理测量学效度。
健康的大学男生（n = 192）参与了这项横断面研究。所有参与者均被告知研究细节。要求参与者完成GAD - 7、睡眠卫生指数（SHI）、感知压力量表（PSS）以及人口统计学细节。
总体而言，GAD总分范围为0 - 21。不存在天花板效应或地板效应问题，因为只有12.5%的参与者报告最低分为0，且没有参与者报告最高分为21。发现GAD - 7的内部一致性分数良好（克朗巴哈系数α = 0.83）。如“斯皮尔曼相关系数（）”所示，项目分数之间的内部同质性为0.22 - 0.57。GAD - 7的总分和单个项目分数与PSS总分在统计学上相关（相关系数 = 0.21 - 0.37），以及与SHI的第8项和第13项分数相关（相关系数分别为 = 0.17 - 0.26和0.21 - 0.40）。GAD - 7项目的探索性因子和验证性因子载荷分别为0.60至0.81和0.51至0.80。
本研究支持使用GAD - 7来评估沙特大学生中的焦虑水平。
