Background: Many scales are used as screening tools for depression in clinical settings and epidemiological research, however, many of them have a large number of items and are only validated in person. Objective: Online validation of the short version of 4 items of the Depressive Psychopathology Scale (DPS-4), taking as a reference pattern the Depression Scale of the Center for Epidemiological Studies (CES-D) through a virtual survey. Materials and methods: A total of 256 people answered the virtual survey, which included questions about sociodemographic characteristics and background, the DPS-4 scale and the CES-D. The structure of the DPS-4 was evaluated and its scores were contrasted with the diagnosis of depression defined by a CES-D score ≥24. Results: Taking the CES-D as the reference pattern, the DPS-4 had an area under the ROC curve of 0.9243 (95% confidence interval: 0.8899 to 0.9587) and the optimal cut-off point was 4 (Youden index: 0.7, sensitivity: 82.19% and specificity: 87.43%). Internal consistency was adequate with a McDonald's Omega coefficient of 0.8229; and a Cronbach's alpha of 0.8126. The item on anhedonia was the one that contributed the most to the measurement of the EPD-4. Conclusion: The online EPD-4 presented adequate psychometric properties, being valid to detect depression taking the CES-D as a reference.
