Prevalence
The correction criteria of the technical manual of SENA19 are used in the study of prevalence. Table 1 presents the number and percentage of Spanish children and teenagers in strict confinement who are between 1 and 2 standard deviations above average, more than 2 standard deviations above average, and the ones that scored higher than the clinical sample of SENA scales. In the aspects of self-esteem, integration and social competence and awareness of the problems, the distance in standard deviations is below average, and those participants who score lower than the SENA clinical sample are also shown.

Note: SD are the ones from the normal population of SENA technical manual. CS= The clinical sample score of the technical manual. *The distance in standard deviations is below average.
Following, the results of the consequences of confinement are described first on children (8 to 12 years old) and then on the teenager sample (13 to 18 years old).
Consequences of COVID confinement in children between 8 and 12 years old
First of all, Student t-tests are carried out as a sample in which the one of our study is compared with the technical standards of each of the SENA scales (Table 2).
As can be seen, once the confinement week is over, there are already significant differences concerning the scales in every dimension besides self-esteem. In all of them, apart from somatic complaints, the clinical situation of children between 8 and 12 years old is significantly worse than the sample of the scales. They show more anxiety, depression, rage control and problems with emotional regulation, rebellious behaviour and worse integration, besides social competence.
The effect sizes found here are bigger than the ones published in the technical manual of SENA19 regarding the differences between the scores of normal population and the clinical sample in rage control problems and rebellious behaviour.

Consequences of COVID confinement in teenagers from 13 to 18 years old
As can be seen in Table 2, after being confined for a week, teenagers show significant differences regarding the scales in all nine evaluated scales. In all of them, besides awareness of the problems, the clinical condition of teenagers between 13 and 18 years old is significantly worse.
The effect sizes of the present study are greater than the ones published in the technical manual of SENA19 regarding the differences between the scores of the normal sample and the clinical one.
Differences between children and teenagers in Covid-19 confinement
In relation to the second goal, in order to compare children and teenager data, the scores of all the evaluated dimensions were standardised taking the average and standard deviation of the SENA scales for children (8 to 12 years old) and teenagers (13 to 18 years old). Then, a MANOVA was carried out with all the mental health variables set out in the study and shared with both groups, that is, all of them except for awareness of the problems.
The differences turned out to be significant (Pillai’s trace=.157, F=13.551, p=.0001, h2=.157). The inter subject tests can be seen in Table 3. Teenagers show higher levels of anxiety, depression, problems with emotional regulation and somatic complaints, as well as lower self-esteem and integration and social competence levels than children. As for children, their sample reaches higher scores in rebellious behaviour than teenagers.

Differences by gender and level of education in children between 8 and 12 years old
Regarding the third goal, ANOVAs of a factor with SENA dimensions based on gender and educational cycle were carried out (Table 4).
There are not significant differences regarding gender in any of the nine evaluated variables in children in quarantine. According to the educational level, the youngest of the middle elementary level revealed greater problems of emotional adjustment than those of the upper level (F=9.061, p=.003, h2=.028).

Differences by gender and level of education in teenagers between 13 and 18 years old
Regarding gender, the results show that there are significant differences between teenagers (Table 5), with females presenting higher levels of anxiety, less self-esteem, more problems with emotional regulation and more somatic complaints than their masculine counterparts. Then again, males show a significantly lower score on integration and social competence than females.

Note. ESO= Secondary, Middle School; Baccalaureate= Sixth Forma, High School
Regarding the level of education, there are significant differences among anxiety, depression, self-esteem, problems with emotional regulation, somatic complaints and awareness of the problems. In all of them, teenagers who study in ESO show a better clinical condition that the ones who study in high school and professional training, except for the scale of awareness of the problems (Table 6).
