*3.1. Prevalence of Having Suffered from COVID-19 among the Participants*

A total of 15.25% (*n* = 61) of the participants had suffered from COVID-19 before the study period, whereas 84.75% (*n* = 338) had not. Figure 1 shows these data categorized based on sex.

*3.2. Association of Psychological Discomfort with Sex, Residence during the Academic Year, Having Suffered from COVID-19, and Feeling Ready for the World of Work*

A Chi-squared test of independency was conducted to determine whether the distribution of psychological discomfort was similar in women and men. The results show significant differences between men and women(X2 = 14.958; *p* = 0.002, 95% CI). There was a greater proportion of women with high scores in psychological discomfort (41.7%) compared to men (24.6%) (Figure 2).

Regarding the study of the correlation between psychological discomfort and residence during the academic year, it was observed that the two variables were correlated (X<sup>2</sup> = 458.823; *p* = 0.026, 95% CI). Table 1 shows the percentages of greatest and least affectation in K-10 (very high level and low level, respectively) as a function of the coexistence unit during the academic year.

In the analysis of the relationship between psychological discomfort and having suffered from COVID-19, no correlation was observed between these variables (X2 = 5.652; *p* = 0.130, 95% CI).

Lastly, psychological discomfort was correlated with feeling ready for the world of work (X2 = 24.873; *p* = 0.000, 95% CI). The participants who responded that "perhaps" they felt ready for the world of work showed greater representation in percentages of very high levels of psychological discomfort. However, the percentages of greatest representation in low levels of psychological discomfort were observed in those participants who responded "yes" to this item (Figure 3).
