Objective: To assess the validity of the Hospital Anxiety and Depression Scale (HADS) for depression and anxiety screening in primary care patients in Colombia. Methods: A criterion validity study was conducted with 243 adults that had completed the HADS and were later assessed using the MINI as a gold standard. Cronbach\'s alpha, McDonald\'s omega and factor structure were applied through confirmatory factor analysis (CFA). ROC curve analysis and Youden\'s statistic were used to determine the cut-off point. Results: Cronbach\'s α was reported to be 0.85 and 0.82 for McDonalds\' ω. CFA supported a two-factor solution demonstrating satisfactory fit. Root mean square error of approximation = 0.04, Comparative Fix Index (CFI) and Tucker-Lewis Index (TLI) = 0.97. For HADS-A, the cut-off point was determined as 6 associated with a sensitivity of 0.76, a specificity of 0.72 and Youden\'s index of 0.50. The ABC was 0.81. For HADS-D, the cut-off point was determined as 4 associated with a sensitivity of 0.78, a specificity of 0.74 and Youden\'s index of 0.53. The ABC was 0.82. Conclusion: The HADS is a valid and reliable instrument for anxiety and depression screening in adult patients of primary healthcare services in Colombia.
