ABSTRACT=<p><bold>Background:</bold> The Overall Depression Severity and Impairment Scale (ODSIS) is a self-report scale designed to evaluate the severity and functional impairment associated with depression.</p><p><bold>Objective:</bold> This study evaluated the psychometric properties of the online version of the ODSIS in Spanish outpatients with depression and anxiety disorders.</p><p><bold>Method:</bold> Patients with a main diagnosis of a depressive (<italic>n</italic> = 283) or anxiety disorder (<italic>n</italic> = 191) and a mean age of 38.15 (<italic>SD</italic> = 12.06) were evaluated with a clinical diagnostic interview and measures assessing depression, anxiety, positive and negative affect, and quality of life. Factorial structure, internal consistency, convergent, and discriminant validity and cutoff scores were analyzed.</p><p><bold>Results:</bold> Consistent with previous validations of the instrument, Confirmatory Factor Analysis showed a unidimensional factor structure. Furthermore, the results obtained supported the internal consistency and construct validity of the ODSIS scores. A score of 5 was found to meet the criteria used in this study for the optimal cutoff score.</p><p><bold>Conclusion:</bold> The results obtained in this study show that the Spanish version of the ODSIS delivered online is an adequate tool to assess the depression-related severity and impairment in a brief and easy fashion.</p>
