There is a need to advance theoretically in the search for variables that can explain a high or low level of Mental Wellbeing. In the present work the bet revolves around the Theory of Multiple Discrepancies and from this it raises the objective of determining if the discrepancy in the level of satisfaction with the personal academic performance and the one of the others is related to the level of Well-being Mental. To achieve this goal a cross-sectional, correlational and non-experimental study was carried out; A sample composed of 550 students from a higher education institution in the city of Durango, in the state of Durango, Mexico, to which the Warwick-Edinburgh Mental Wellbeing Scale was applied, compared the level of satisfaction With the personal academic average and the level of satisfaction with the academic average of the peers in students with low and high level of Mental Well-being. The results in the low group indicate a Pearson r value of .063 and a significance level of .817 and in the high group a Pearson r value of .434 and a significance level of .000 by which they indicate That the students with low level of Mental Well-being manifest a discrepancy between both questions, while those with a high level of Mental Well-being show agreement between both questions. In this sense, the theoretical hypothesis, at this level of the discrepancies, raised by this theory is contrasted.
