1. Introduction
Adolescence is a transitional stage between childhood and adulthood, covering approximately between 10 and 19 years of age, and is based on a social construct where the formation of identity, formal thinking, and sexual maturity occurs. It is a growth phase exposed to various risk factors [
1] and can be conceived of as a vulnerable stage, due to constant changes in biological, cognitive, social and family functioning. Adolescents are exposed to greater sources of stress and intense emotions, such as separation from parents, bullying, academic performance, interaction with peers, etc., among many others [
2].
Another vulnerable situation has been the COVID-19 pandemic, as a historic event that has had an uneven impact on various spheres of personal and social life. The major unprecedented health measures included social distancing and quarantining, dictated in Spain through Royal Decree 463/2020 [
3], which has had a great impact on people in terms of their physical, mental, social, behavioural, learning and developmental health. The duration of restrictions, uncertainty, lack of information, family economic stress, lack of space in the home and lack of essential supplies acted as key factors in the emergence of psychological reactions [
4,
5]. In the adolescent population, this situation has had a significant effect [
6,
7]. Even after the restrictions were lifted, risk factors such as illness or loss of loved ones, insomnia, irritability, difficulty concentrating, post-traumatic stress disorder, substance use, as well as the appearance of depressive symptoms or anxiety have persisted after the pandemic. This situation has increased the possibility that a section of the population presents psycho-pathological disorders both in the present and in the future, considering their level of vulnerability [
8].
Adolescents have a high prevalence of mental disorders, around 20%, and the possibility that individuals’ experiences can be perpetuated in adulthood, greatly influencing and shaping their future social interactions and emotional well-being [
6,
7,
9,
10]. Emotional difficulties can have serious consequences on the lives of adolescents, including mental health problems and difficulties in establishing healthy relationships [
11].
The transdiagnostic approach does not draw a specific line of separation between internalising and externalising symptoms, since it emphasises the mechanisms or cross-cutting factors that may be present in both disorders, such as negative thinking patterns, emotional regulation skills or difficulties in interpersonal relationships [
12].
However, other researchers divide mental health problems according to whether they are internalising or externalising [
13]. Internalising symptomatology refers to difficulties experienced internally and manifested at a cognitive or emotional level, such as anxiety and depression. While anxiety can be defined as our body’s response to certain stimuli triggered by a reaction that activates our nervous system [
14,
15,
16], depression is characterised by sadness, loss of interest, fatigue, changes in appetite or sleep and lack of concentration [
16]. Between 13 and 17% of the population presents anxiety and up to 67% could manifest depressive symptoms [
10,
17]. Externalising symptomatology, on the other hand, is characterised by disruptive and aggressive behaviour that is directed towards other people or the environment, such as anger and aggression [
16]. While anger is defined as a normal and common emotion that can occur in varying degrees of intensity [
18], aggressiveness refers to the ability and intent to cause harm, whether physical or psychological, to another person, and can manifest itself through kicking, scratching, screaming, pushing, swearing, etc. among other behaviours. Externalising symptomatology usually has a prevalence of around 6 to 10% of the population [
10,
19]. This type of behaviour has a great impact on the life of the child or adolescent and on their school development [
20], and is crucial in the mental health of the child and adolescent population, as they can have a significant impact on the development and well-being of the person, due to the strong impact on their immediate social and family context, as well as on their socio-affective development [
21].
Some research indicates that there are relevant differences between genders, so it could be a modulating variable in early adolescence [
14]. Specifically, women would be up to four times more likely to develop emotional imbalances than men and experience a greater incidence of mental health disorders [
22]. On the one hand, women would have higher scores in internalising symptomatology than men [
14,
22,
23]. In contrast, some studies do not find any gender differences in anxiety and depression in adolescence [
24,
25] and others do not find these differences in early adolescence [
9]. On the other hand, men tend to present higher levels of aggressiveness as a manifestation of emotional imbalances [
24,
25] while women tend to manifest contained rage or anger, without reaching behavioural manifestations [
28]. In this regard, there could be gender differences in externalising symptomatology. Other research, in contrast, does not find these differences in anger or aggressiveness between genders [
22].
Adolescents also have psychological resources that enable them to face these challenges effectively and adaptively [
19,
29], and these play a fundamental role in coping and psychological protection, life satisfaction and emotional well-being [
29], such as self-esteem, social competence and awareness of problems, among others. Self-esteem is a person’s subjective and global perception of their own abilities, competences and personal traits, and this influences the way we see ourselves and how we relate to others [
30]. In adolescence, self-esteem has been found to play an important role in the generation of emotional stability and lasting well-being [
29]. Specifically, it appears that women have a lower level of self-esteem than men [
31], both in the global and in the specific dimension for the physical, social or academic domain, which indicates that girls could have more negative visions of themselves than boys. In contrast, other studies carried out after the pandemic do not record this clear pattern, but it may be mediated by other variables, such as the self-perceived needs of boys and girls [
32]. Social competence and integration is the ability to adapt to the norms and rules of a community and apply social skills in social interactions with others [
33]. Adolescents with a greater repertoire of social skills have higher self-esteem, fewer negative feelings, better school performance, and fewer behavioural disorders [
34]. In particular, women may have greater difficulty in communicating and expressing their emotions, which could have an impact on having more unstable social networks [
35]. However, other studies do not find any gender differences in terms of social competence [
36], so boys and girls would not display any differences in the social skills they bring into play in their social relationships. Finally, awareness of problems is related to the ability of people to realise the difficulties they have in their day to day lives, being aware that they must change and seeking help from others to be able to do so [
37]. Women tend to be more aware of their difficulties [
31], perceive and understand emotions better than boys, and this may be associated with a higher risk of developing emotional problems [
38].
Thus, self-esteem and social competence and integration are considered positive protective factors, since they predict psychological well-being in this age group, mainly because they promote more rewarding interpersonal relationships and bolster the subject’s ability to deal with everyday difficulties [
30,
34,
35].
In summary, internalising and externalising symptomatology may be frequent in adolescents after COVID-19 experiences, and may have a significant impact on their personal development and psychological well-being. On the other hand, personal resources, such as self-esteem, social competence and integration, and awareness of problems can act as a protector against these emotional difficulties. Some research indicates that there may be differences in the expression of these emotional difficulties according to gender [
31,
34,
35,
38] or not [
22,
24,
25,
36]
Therefore, the objective of the research is to analyse the socio-emotional difficulties (internalising and externalising) as well as the relationship with personal resources (self-esteem, social competence and integration, and awareness of problems) according to gender in adolescence after the situation created by COVID-19. Firstly, girls are expected to have a higher incidence of internalising and less externalising symptomatology compared to boys, and secondly, socioemotional difficulties and personal resources are expected to be related in both adolescent boys and girls.
4. Discussion
The objective of this study is to analyse the internalising and externalising symptomatology according to gender and the relationship with personal resources in adolescence after the COVID-19 pandemic.
The first hypothesis expected to find a higher incidence of internalising symptoms and lower externalising symptoms among the female participants. The results of this study indicate that the group of female participants has higher scores in anxiety, depression and anger than the male participants, while there are no statistically significant differences between the groups in terms of aggression, so the hypothesis cannot be partially maintained.
On the one hand, the female participants score higher in internalising emotional symptomatology (anxiety or depression) than the male participants, which coincides with several studies [
15,
22,
23,
45]. It seems that women tend to have higher scores in internalising variables than men, since they do not usually manifest emotional problems, but develop other cognitive patterns of internalisation of emotional difficulties. On the other hand, some studies [
21,
26,
27,
46] conclude that men are more likely to exhibit aggressive behaviours, and that women tend to experience fewer externalising behaviours than men. This study differs, since higher levels of anger have been found among the female participants who, although they might not engage in transgressive external behaviour, may engage in explosive verbal violence, as other studies find. For example, Oliva et al. [
28] examined gender differences in behaviour disorders in adolescents and found that women showed higher levels of defiant behaviour and anger. Other studies have also not found differences in aggressive behaviour between genders [
26,
27]. This maladaptive pattern present in women is detrimental to their mental health and emotional well-being, since it implies not manifesting their emotions and ideations, which prevents them from being helped by others and without possibilities for improvement.
These differences found between genders can be attributed, for example, to biological, social and cultural influences [
21]. Some authors [
47] examine neurobiological differences between men and women, finding that higher testosterone levels in men may be associated with an increased propensity towards physical aggression. However, in our study, there are no differences in this variable, but rather they could indicate a gender gap, since women would tend to internalise the daily setbacks and not manifest them, as expected in the case of men [
14,
23,
28]. Social and contextual factors, such as the influence of family, peers and culture, could contribute to gender differences in emotional difficulties. Adolescents might perceive as normative various permitted forms of expression of internal or external symptoms as more appropriate according to the role assigned in society. For example, experiences of differential socialisation, where certain behaviours are reinforced based on gender, can influence the way men and women express anger or aggression [
48].
The second hypothesis states that internalising and externalising symptomatology and personal resources are related in male and female adolescents. The results of the study indicate that there is a high and significant relationship between socioemotional difficulties and personal resources, although in the group of male participants the indexes are higher than among the female participants, so the initial hypothesis could be maintained.
Regarding the relationship of personal resources with internalising symptomatology according to gender, [
15] conducted a study that included the variables self-esteem and anxiety, and determined that there was a negative relationship between both variables, since, at higher levels of self-esteem, lower levels of anxiety as a state and trait were exhibited. In addition, if adolescents display a very intense level of anxiety, it would trigger excessive sensitivity, which would lead to a decrease in self-esteem. Likewise, these authors argue that the anxiety presented by students depends on their ideas about the task that is demanded of them, but also on their ability for understanding and self-control.
There is also a high relationship between self-esteem and depression in adolescents, since having low self-esteem can lead them to feel devalued and experience negative feelings of self-worth, affecting their emotional and mental state, causing symptoms of depression such as sadness, irritability or feelings of guilt [
17].
Thus, internalising difficulties are related to personal resources since coping resources favour the balance between the demands of the environment and the internal needs of the adolescent according to gender. Hence, the group of male participants presents lower levels of emotional problems because they have higher levels of self-esteem and social competence than the group of female participants. Aguilar [
35] describes a difference between adolescent boys and girls regarding their psychosocial adjustment and points out that adolescent girls have less self-esteem, perceive their own conflicts to a greater extent, and participate less socially. The fact that women communicate less with their support networks and are less socially active can be considered a risk factor since being able to talk safely about their feelings with their parents or people close to them can be a protection factor when developing a more positive self-perception and better coping styles [
29,
31,
34].
Stegge and Terwogt [
49] examine the role of emotional intelligence and self-esteem as mediators of externalising symptomatology in early adolescence. The results showed that self-esteem partially mediated the relationship between emotional intelligence and behavioural disorders, suggesting that positive self-esteem may help mitigate them.
Associations between externalising problems in adolescence, mental health and social competence and integration were also investigated. The results showed that social competence and integration act as a mediator in the relationship between externalising behaviours and mental health, suggesting that having adequate social skills can reduce socioemotional difficulties and improve emotional well-being [
50]. They also examined its role as a mediator in the relationship between aggression and substance use in early adolescence. The results showed that social competence and integration mediate the relationship between aggression and substance use, indicating that the lack of this factor can contribute to the manifestation of aggression and the consumption of toxic substances [
51].
Some studies indicate that there are gender differences from early adolescence onwards. [
45,
50] explain that the self-perception of boys interacts with their anxiety levels in a U shape; that is, during early adolescence they have higher levels of anxiety and lower levels of self-confidence; however, when they reach the stage of full adolescence the relationship becomes inverse, that is, self-confidence increases and anxiety decreases. However, in the case of girls it does not happen in the same way. Girls from early adolescence onwards begin to show high levels of anxiety and a decrease in self-confidence that will gradually increase until the critical stage of adolescence. Therefore, girls will have a poorer perception of themselves and greater awareness of their difficulties, accompanied by higher levels of anxiety, from the middle stage of childhood compared to boys. Thus, the evolution of gender differences throughout adolescence could be different for girls and boys, since some studies indicate that at the beginning of adolescence girls are twice as likely to present emotional disorders, which then triples between 13 and 15 years of age, decreasing from the age of 16 and remaining stable in adulthood [
52].
The socio-emotional problems of adolescents have also been aggravated by the recent pandemic, and social patterns have even changed. According to Resa’s study [
53], having been isolated at home has caused some intense emotions to overflow, and teens have had to connect with unpleasant emotions. All this causes a series of bodily sensations that can manifest in muscle tension or even anxiety. Many adolescents have shown social and emotional vulnerability after this health crisis, so it has directly affected the socioemotional adjustment of adolescents, causing them higher levels of anxiety and depression.
5. Conclusions
In conclusion, women and men have socioemotional difficulties, but different kinds, since women tend to express more anxiety, depression, and anger than men, with no differences in aggression, showing a more maladaptive pattern. These differences may be due to biological, social and cultural influences, as well as COVID 19 situations of vulnerability. In addition, personal resources such as self-esteem, social competence and integration, and awareness of problems, have a negative relationship with them. A higher level of these resources is associated with a lower incidence of emotional deficits, so they play a protective role for adolescents.
It is important to mention some limitations of this study. Firstly, the research was based on samples from the same province, which may not be generalisable to the rest of the population. In addition, a self-reporting approach was used, which may be subject to biases and limitations in the accuracy of the data collected.
Future research could be aimed at conducting longitudinal studies, to record the evolution of socio-emotional problems and personal resources throughout adolescence and young adulthood, and to see if these patterns are maintained or vary. It would also be interesting to triangulate information from adolescents with data collected by family and teachers, especially in internalised symptomatology.
The findings of this study have significant educational implications. The results highlight the importance of promoting the development of personal resources in adolescents of both genders, as part of the support and prevention programmes delivered in schools [
10,
12]. Social skills training programmes can be implemented to help teens improve their ability to communicate, resolve conflicts, and relate to others in a healthy way. The promotion of positive self-esteem, social integration and competence, as well as awareness of problems, can help reduce emotional difficulties and promote healthy adjustment in adolescence in both genders.
