Depression is a disease, a public health problem and is related to self-esteem, which is the degree of self-worth, which in turn influences family functionality, as an important key to the development of its members; The research is cross-sectional and confirmatory, of the non-probabilistic sample of 115 higher education students from the city of Tacna to determine the adjustment indices of the explanatory model of the Family Functionality Scale based on Selfesteem and Depression; which X2 / gl = 27.352, CFI = 0.086, GFI = 0.729, were not acceptable, only SRMR = 0.3798 was adequate, but globally we can conclude that the fit indices of the explanatory model between family functionality related to self-esteem and it is related Depression is not appropriate in higher education students from Tacna.

The present research work aims to determine the psychometric properties of the Rosenberg self-esteem scale; It is instrumental, involving a sample with 115 higher education students from Tacna between 18 to 55 years old. Item analysis, exploratory analysis, confirmatory analysis, bifactor, parallel analysis, reliability were performed and percentiles were determined. The results indicate that items 6 and 8 are not adequate for the negative dimension and this same dimension is not adequate according to the total variance explained; In the confirmatory analysis, the GFI adjustment index was not optimal, the parallel analysis using the least squares method recommends two dimensions and explains 59% of the explained variance, it was analyzed according to the adjustment indices for a bifactor that cannot be a one-dimensional scale.
