The multiple logistic regression analysis indicated higher total GAD-7 scores (OR = 1.9, 95% CI: 1.8–2.1) and fatigue scores (OR = 1.2, 95% CI: 1.1–1.4) were the only unique, statistically significant predictors of elevated depression levels within the guardian sample (see Table 2). Here, GAD1 is linked to major depressive disorder.
