**4. Results**

As the variables used were quantitative, the correlation index that expressed 'an estimation of the degree to which two variables vary together' was analysed, in order to study the relationship between the thirteen factors assessed by the questionnaire [40]. Pearson's correlation coefficient was employed in order to analyse the relations between variables, considering those associations that were significant at a confidence level of 0.99 and 0.95. Moreover, the size of the correlation was valued as low, moderate or high, in accordance with the recommendations made by Bisquerra [39] in the field of educational sciences. In light of the wide range of the variables, the most important findings will be discussed in connection to the different types of factors. Table 4 shows the factors correlation matrix.
