Abstract Objective A longer duration of untreated illness (DUI) has been associated with poorer outcomes across several mental disorders; however, few studies have investigated DUI in anxiety disorders, particularly in generalized anxiety disorder (GAD). This study aimed to identify sociodemographic and clinical factors associated with a longer DUI in GAD. Methods We conducted a cross-sectional, multicenter study, retrospectively reviewing the medical records of GAD patients from three mental health services. Sociodemographic and clinical variables were extracted for analysis. One-way analyses of variance and Pearson’s correlations were used to examine the relationship between DUI and categorical and quantitative variables, respectively. A multivariate linear regression model was then conducted to identify variables independently associated with DUI. Results The total sample included 243 patients; the mean DUI was 30.92 (±65.25) months. In the final model, a longer DUI was associated with an earlier age at onset ( B = −0.428; p = 0.023), a longer duration of illness ( B = −0.431; p < 0.001), and the presence of multiple side effects ( B = 55.778; p < 0.001). There was a trend toward statistical significance for the association between a longer DUI and multiple medical comorbidities ( B = 13.122; p = 0.076). Conclusions Our findings suggest that reducing the time between the onset of GAD and the initiation of appropriate pharmacological treatment may improve clinical outcomes, mitigating the risk of a chronic course of illness. Further studies are needed to elucidate the role of DUI as a prognostic factor in GAD.
