Depressive disorders generate significant disability and are among the most prevalent at present (Organización Mundial de la Salud, 2015). Therefore, it is necessary to have psychological instruments to detect these disorders. One of the most used scales is the BDI (Beck Depression Inventory), in its first version is free. In this work we studied the internal structure and reliability of the BDI scale (Beck, Rush, Shaw and Emery, 1979) in university population of Michoacan (Mexico). It was applied the BDI scale to 1190 university students aged between 17 and 38 years (M = 18.78,SD = 1.72) and the majority were women (n=801, 67.3%). A Principal component analysis was applied, our results suggest a structure of two factors, corroborated by a Confirmatory Factor Analysis (c2/df = 1.85; NFI = .910; CFI = .956; RMSEA =.027). A high reliability of the total scale was observed (α = .898) and it was also adequate for the 2 factors (α = .866,α = .701). The results indicate that the BDI is adequate to apply to the university population in Michoacan. Descriptive data are also offered in the university population of Michoacan(Mexico). No relationship was observed between the total score of the scale and age, but the mean of the women was higher than that shown by the men. Stresses that up to 13.3% of the sample can meet criteria of depression.
