Finally, we could have investigated in relation to the variables that predict school results in this population. We could also have analyzed the differences between students with externalizing disorders versus internalizing. Likewise, to know with certainty the adequacy of the information from the factor analysis for the data set, it is necessary to perform a confirmatory factor analysis. We are indicated these elements as limitations of the present investigation. We will investigate future research in relation to these elements.
