- 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.
