1. Introduction
The COVID-19 pandemic has significantly affected the daily life of millions of people around the world and Italy was the first, among Western countries, to introduce strict social restrictions [
1,
2,
3]. Initially, lockdown measures were limited to the Lombardy region, in Northern Italy, and few days later the restrictions became national [
4,
5]. During the following two years, Brescia and Bergamo districts, both in Lombardy, remained the two cities with the highest alert level and with the strictest isolation measures. It is well-known that social relationships are an important determinant of health, alongside education, lifestyle, environment, employment and working conditions [
6]. Physical distancing, online schooling, restrictions on social meetings and physical and outdoor activities have profoundly affected children’s and adolescents’ habits. An increase in psychological distress and a high prevalence of COVID-19 related fear were reported among children and adolescents since the beginning of the pandemic [
7,
8].
Adolescence is commonly considered as the developmental phase that begins with the physiological changes of puberty and ends with the establishment of a personal identity and adult roles. According to the World Health Organization (WHO), adolescence roughly corresponds to the period between 10 and 19 years. Recently, the age range has been broadened due to the prolonged process of achievement of adult roles which is common in contemporary societies [
9]. The American Academy of Pediatrics suggests 11-21 years as an optimal interval that includes the different stages of adolescence [
10].
Adolescence is a formative period in life that encompasses several physiological and psychological changes which directly affect lifelong health. Adolescents are particularly at risk, given that this period of development is pivotal for psychological and biological changes and can be decisive in setting individual behavioral trajectories which influence adulthood [
3,
6,
7,
8,
11].
In the long trajectory that leads from childhood to adulthood, young people are faced with a range of developmental tasks, such as mastering skills, forming close relationships, exploring different roles, accepting bodily changes, establishing gender identity, envisioning their future, and acquiring the essential abilities and values needed for a successful transition into adulthood. Following Erickson’s (1968) theory of psychosocial development, the main developmental task of adolescence is the adult identity formation, namely the awareness a person has of being him/herself and different from others, including all personal attributes and the feeling of continuity over time despite changes [
12]. Furthermore, to define his/her own identity, the adolescent must renegotiate aspects of separation from parental figures and build aspects of him/herself on which to base his/her own personal identity. These processes imply great emotional intensity and their resolution is not obvious but is the result of strenuous psychic work which Erikson (1968) defined as a “maturational crisis” [
12].
Notably, the concept of “crisis” is positive and dynamic in Erikson; nevertheless, the complexity of fulfilling these developmental tasks makes adolescence a phase of increased psychological vulnerability. Recent literature highlights that mental health needs in young people have grown over the past 10 years before the pandemic. According to WHO (2021), 13% of 10–19-year-olds experience mental health issues which are largely unrecognized and untreated [
13]. A study prior to the pandemic estimated the global prevalence of unmet needs of mental health care among adolescents being more than 50% [
14].
In this scenario, the Covid-19 pandemic intervened as a further factor negatively affecting the emotional well-being of the adolescent population. In particular, the confinement associated with the pandemic has interfered with their daily lives, affecting adolescents’ vital need for social interaction with peers, disrupting the normal rhythms of school life, hindering the possibility of outdoor leisure activities and of carrying out regular sporting activities. In this context, the perception of loneliness has increased among adolescents, which could have played a part in the psychological suffering of young people during the pandemic. An extensive literature has underlined the critical impact of the Covid-19 pandemic on the rates of anxious, depressive and psychopathological disorders in the general population and especially in young people [
15]. A meta-analysis study on the global prevalence of anxiety and depression in children and adolescents found a likely doubling of psychological difficulties since the start of the pandemic [
16]. The pooled prevalence of clinically elevated symptoms of depression and anxiety in the pandemic period reached 25.2% and 20.5% respectively, while before the pandemic prevalence was at 12.9% for depression and 11.9% for anxiety. Anxiety and depression symptoms showed an upward trend as the pandemic progressed and were higher in girls, while depressive symptoms increased with age [
16].
These results are confirmed in a further study in the USA, where there was a 12% increase in the odds of adolescents using Mental Health Services during COVID-19 and the odds ratio of females, compared to males, increased significantly by 63% during the pandemic [
17]. A recent study carried out in Italy over the different periods of the pandemic (from March 2020 to May 2022), pointed out that the access to emergency departments for acute psychiatric issues, both those for any reason and those for suicide attempts in children and adolescents, has grown impressively (a two-fold increase) from the period before the pandemic to its conclusion, peaking in the second wave [
18].
Quality of life has also been severely affected during the pandemic. Several authors explored changes in physical activity, mental health, sleep quality, screen use and eating behavior [
19,
20]. Xiang et collaborators have detected a worrying increase in sedentary behaviors and time spent in front of screens among adolescents in China, with the percentage of physically inactive students increasing from 21.3% to 65.6% [
21]. Bruni et al. reported changes in sleep habits with difficulties in falling asleep and an increase of screen use in Italian adolescents [
22]. A survey on children and adolescents living in South Tyrol, in the North of Italy, conducted in 2021, confirmed the presence of mental health problems, emotional symptoms and poorer quality of life after the first year of the pandemic especially in children and adolescents with low socioeconomic status, migration background and limited living space [
23]. These findings were aligned with a similar study conducted in Germany where two-thirds of the children and adolescents reported being highly burdened by the COVID-19 pandemic, experiencing a reduction of the quality of life and an increase in anxiety and mental health problems compared to the pre-pandemic period [
24]. In the large Norwegian COVID-19 Young study, comprising participants aged 11–19 years, Lehmann and co-workers noted a significant increase in internalizing problems between the lockdown in April/May 2020 and 9 months later in Dec 2020/Jan 2021 [
25]. In a recent systematic review, Orban and collaborators concluded that symptoms of depression, anxiety and mental health issues in children and adolescents increased during the pandemic compared to before and remained high for a long period after the onset of the pandemic [
26].
Not many studies have looked at changes in eating behaviors in young people during the pandemic [
27]. Zanini and colleagues [
28] found a general improvement in the eating habits of adolescents in northern Italy. Nonetheless, another Italian study found an increase in eating disorders in male and female adolescents during the pandemic [
29].
To assess the extent of long-term changes in emotional well-being and several aspects of lifestyle, including eating habits, physical activity and technology addictions, we designed a web-based survey addressed to adolescents, two years after the onset of the COVID-19 pandemic, during a period of slow “return to normal”.
Considering the amount of literature documenting the increase in emotional distress among young people during and following the pandemic, exploring the reasons for adolescents’ discomfort in more depth may provide worthwhile insight to promote better psychological adjustment and developmental outcomes. To this aim, we dedicated part of the research to collect the reasons for distress through free text questions, to capture its nuances and contents more richly.
Investigating these aspects among adolescents may also contribute to address public health actions to prevent the development of numerous chronic or degenerative diseases in adulthood [
30].
Following the recently published findings on changes related to eating habits in pandemic, in this article we analyzed the effects of the pandemic on the psychological well-being of the adolescent population in the province of Brescia, even when strict restrictions or lockdown measures were no longer in place [
28,
31].
2. Materials and Methods
The results of the present study are a part of a larger cross-sectional observational study, named COALESCENT (Change amOng ItAlian adoLESCENTs) and conducted in collaboration with and under the supervision of the Territorial School Service of Brescia District. The main tool of COALESCENT was a web-based survey developed using the open-source software LimeSurvey (LimeSurvey GmbH, Hamburg, Germany). We submitted the online survey proposal to all high schools of the Brescia district (39 state and 18 state-authorized private schools); among them, eight schools agreed to collaborate. Students who were willing to participate provided an online informed consent before starting the questionnaire; for underaged students a parental consent (following approved procedures in each school) was provided; the survey was administered during school hours. The questionnaire consisted of 110 questions, divided into 8 sections, detailed elsewhere [
28]. For the purpose of the present sub-analysis, in this section we provide details about sections F (questions about physical and sport activity, duration and quality of sleep, duration and type of screen activity, smartphone addiction) and G (6 questions about emotions).
Section F. Physical activity was investigated with six questions, then grouped into a single data indicative of a high, medium or low level of physical activity performed daily by the participants. Two questions explored if they were engaged in a sports club before the pandemic period and if they definitely dropped out after the period of Covid restrictions. Three questions collected self-reported sleep duration and changes in sleep quality and duration, compared to the pre-pandemic period. Time spent in screen activity, in comparison to the period before the pandemic, was self-reported and divided into three categories: for study, for fun and out of boredom. To assess smartphone addiction we used the validated questionnaire, Smartphone Addiction Scale - Short Version (SAS-SV; [
19,
32]). This scale is a 10-item questionnaire developed in Korea measuring the risk level of smartphone use with the aim of identifying high-risk groups among adolescents. The total score ranges from 10 to 60, with higher scores reflecting higher problematic use of a smartphone in the past year. The Italian version was validated by maintaining the original cut-off score indicating probable smartphone addiction (31 for males and 33 for females) [
32]; a further Italian study suggests a two-factor structure, namely “addiction” (which refers to the emotional involvement and irresistibility of attraction) and “functional impairment” (which refers to to the degree of interference in carrying out daily activities and studying) [
33].
Section G. The tool investigating emotional distress was the Matthey Generic Mood Questionnaire (MGMQ), standardized short questionnaire assessing the presence, impact and reasons for possible emotional distress [
34,
35]. The MGMQ consists of 4 questions, which we have slightly adapted for this study compared to the original: the first (Distress) question asked, “In the last 2 weeks, have you felt any of the following for some of that time: very stressed, anxious or unhappy, or found it difficult to cope?” Responses options were “yes”, “possibly” or “no”. Respondents who answered “yes” were asked the second (Bother Impact) question, “How bothered have you been by these feelings?”. Responses options were “not at all”, “a little bit”, “moderately” or “a lot”. The threshold for having a potentially clinical relevant distress condition is having chosen the “a lot” or “moderately” bothered response option. Based on these responses a binary variable “distress” with option “yes/no”was created, where “no” included adolescents who answered “possibly” or “no” to the first MGMQ question in addition to adolescents who answered “not at all” or “a little bit” to the second MGMQ question. A third “Reason for Distress” question (if the Bother Impact question was endorsed) is an open question aimed at assessing the reasons behind the distress. A fourth question ‘Wish for Referral’ was modified by asking participants if in the last two years they had turned to professionals such as psychologists or psychotherapists more often compared to the pre-pandemic period. The MGMQ has been validated in the field of perinatal emotional well-being and has been translated and adapted to the Italian population [
35,
36].
2.1. Statistical Analysis
The analyses included descriptive statistics (i.e., frequencies and percentages for categorical variables and mean values with standard deviations for continuous variables). Comparisons between groups were made using the chi-square test for categorical variables and the Mann–Whitney test for continuous variables. A binary logistic regression model was carried out, with “distress” as the dependent variable. The covariates to be included in the final model were selected on the basis of univariate analysis, with a univariate p value < 0.05 as the main criterion. Then, using a backward selection process, statistically non-significant variables were excluded. To check for collinearity among the variables, the Spearman correlation test was used. Internal consistency was measured using Cronbach’s alpha with a range between 0.70 and 0.95 considered acceptable [
37]. The results of the logistic regression are reported with adjusted odds ratios and 95% confidence intervals. A p-value less than 0.05 was considered statistically significant for all analyses. Statistical analyses were performed using STATA (Stata Statistical Software: Release 18.0 College Station, TX, USA: Stata Corporation).
2.2. Analysis of Free-Text Answers
Free-text answers were evaluated through both a lexical and a thematic analysis. The lexical analysis was carried out by copying the answers in a .txt file which was uploaded to the software MaxQDA (Verbi Software 2024). The software was used to calculate the frequencies of each word used in the corpus and produced a word-cloud, that is, an image made of words, whose size varies according to the frequency with which they recur. Word-clouds are constructed from the most frequent content words (i.e., nouns, adjectives, verbs, and adverbs) in the corpus; an exclusion list was uploaded to the software, so as to exclude function words (i.e., determiners, prepositions, auxiliaries). These are usually excluded from linguistic analyses based on frequency, because they are by their very nature very frequent linguistic elements in a given language and therefore not characteristic of the individual corpus of texts examined; conversely, content words possess semantic content and contribute to the meaning of the text in which they are used. The WordCloud includes word forms instead of lemmas, i.e., each possible form of a word as it is used in the corpus instead of one single umbrella term comprising all its possible word forms. This is useful to identify the differences between, for example, the use of the singular noun “situation” (as in: “the general situation makes me feel anxious”) and the use of the plural noun “situations” (as in: “different situations making me feel anxious”), as well as to notice patterns of usage (for example, verbs used in the first-person singular form). The complete list of words included in the WordCloud together with their overall frequencies in the corpus is given in the
Supplementary Materials. Word forms belonging to the same lemma are grouped together in the table.
The thematic analysis was carried out through close reading of each answer. Two researchers thoroughly familiarized themselves with the contents of each answer and then coded them by identifying each theme expressed (as in many cases, participants expressed more than one cause for distress). The authors conducted an inductive semantic description of the data set following the guidelines provided by Braun and Clarke [
38].
4. Discussion
The objective of the study was to evaluate the presence and reasons for distress among adolescent students from northern Italy in the final phase of the pandemic, together with its impact on their well-being and lifestyles. The vast majority of young participants said they felt definitively (65%) or possibly (10.8%) distressed. Furthermore, the percentage of participants who admitted to experiencing a fairly or very disturbing distress situation (above the threshold of clinical interest) was notable, exceeding 50%. This result places our study in line with the other studies carried out in Italy and elsewhere in the world [
15,
16,
18], finding a worrying increase in the psychological distress of young people during the pandemic and in its subsequent phases.
One of the aims of the study was to analyze the factors most associated with adolescent distress. As in previous studies [
16,
17,
18,
39,
40], in our sample symptoms of distress increased with age and were higher in girls. The most distressed age group was between 16-18 years old, a moment of middle to late adolescence that is central to the development of identity and where relationships with peers are of enormous importance [
12]. In adolescence, the crucial role of context and social experiences for brain development and for the construction of identity has increasingly been recognized. During these phases, the progressive maturation of the prefrontal cortical areas elevates reflective thinking skills, the ability to evaluate dangers, self-judgment, self-image, and the ability to assess one’s skills in comparison with peers and with respect to adults’ expectations, making sociality a decisive aspect [
41]. Thus, this result seems to underline that middle adolescence is a sensitive phase with respect to the challenges presented by the pandemic, especially social restrictions and the threat posed by the Covid-19 disease. The double percentage of girls suffering from clinical distress is a very worrying fact, already known but exacerbated by the pandemic, that should lead to thinking about prevention projects that pay attention to gender aspects.
Several lifestyle factors were significantly associated with distress, while socio-demographic aspects such as level of parents’ education or the type of school attended were not. One aspect which was specifically investigated by this study were adolescents’ eating habits. A new and interesting result is that adolescents who pointed out that their eating habits had worsened during the pandemic, said that they ate less, and made greater use of comfort food were also those at greater risk of emotional distress. This result supports the idea that psychological well-being and correct nutrition are two profoundly linked aspects and that nutrition must be taken into account when designing interventions to promote well-being and prevent emotional distress [
42].
Based on univariate analysis, inactive adolescents seemed to be more distressed compared to active adolescents. Moreover, those who had abandoned their commitment to a sports club during the pandemic showed greater distress than adolescents still engaged. However, this tendency was weak and not significantly evident in the regression model. Notably, in the free-text questions many adolescents expressed their difficulty to reconcile the demands of sports training with school and confinement. Therefore, in our sample, physical activity seems to have a multifaceted role in relation to well-being and distress.
In line with previous literature data, sleep also proved to be associated with distress as the most distressed adolescents said they were sleeping less than in the pre-pandemic period, and that their sleep quality had worsened. Sleep difficulties emerged also in the free-text answers as an aspect of discomfort, together with excessive use of digital devices. Indeed, it is widely recognized that sleep problems and distress are associated with smartphone overuse, as the association between the widespread phenomenon of using digital devices at night and psychological distress was identified even before the pandemic [
33].
Our study further shows that about 50% of the sample was at risk for potential smartphone overuse and that the SAS-SV score proved to be associated with the presence of distress, even though the association was weak [
19]. What emerged in particular was the association between distress and overuse of digital devices when studying (therefore linked to distance learning during the pandemic), or out of boredom. This result seems to suggest that the physical and social restrictions imposed during the pandemic could have exacerbated pre-existing negative lifestyles and habits, such as overusing smartphones to relieve boredom. Interestingly, in a more in-depth analysis of the factors constituting smartphone overuse, it has been noted that “functional impairment”, i.e., the interference that adolescents feel due to smartphone overuse when carrying out daily tasks, was the most significant factor. This testifies to how an excessive use of the smartphone may lead to the perception of a fragmentation of attention and to increased difficulty in completing tasks, contributing to a further increase in distress. Furthermore, the use of digital devices was not associated with distress when used for leisure. As we know, during the pandemic the use of technology has been very important to maintain social contacts despite physical distancing. Thus, this result seems to confirm what was found in a recent study [
43] which demonstrated how connectedness, enabled by new virtual technologies, was a lifeline for young people, a buffer against the devastating effects of physical distancing.
Finally, the sheer percentage of adolescents who clearly stated that they had perceived an increase in their experiences of anxiety (63%), that they were afraid of getting sick (48%) and that they needed to resort more to psychological help (23%) further confirms the relevance of their perceived emotional distress. Moreover, the increase in access to emergency departments for acute psychiatric issues, especially in girls towards the end of the pandemic, calls for some reflections regarding the long-term effects of what was experienced by the young population during the pandemic period [
18,
39,
40,
44,
45].
Exploring the reasons that adolescents themselves identified as the cause of their distress opened a window into the deeper and inner world of young people’s emotional experiences. It is recognized that disclosing one’s emotions or difficulties is a truly difficult aspect for adolescents. Nevertheless, it seemed that many adolescents welcomed the opportunity to communicate aspects of their emotional experience, suggesting an underlying need to feel one’s discomfort listened to, perhaps favored by anonymity: more than 70% of young people with distress agreed to describe the reasons for their feelings, and those who perceived it most did so to a greater extent. Indeed, adolescents who exceeded the clinical threshold for distress were more likely to report profound psychological distress or relational problems in their free-text answers.
Adolescents’ answers showed that school was one major cause for distress, especially because of the pressure they felt to perform well in tests, to keep up with classes and commitments, in order to meet their parents’ and teachers’ expectations. Difficulties in interpersonal relationships, either with their families or their peer groups, were the second most frequently mentioned cause for distress; and impressively, the third were profoundly negative emotional states such as anxiety, fear of failure, or lack of motivation, which in a worrying number of answers led to extreme behaviours such as eating disorders, self-harm, and suicidal ideation. The pandemic then appears as the fourth reason for distress, especially in terms of the deprivation of social contacts with peers and constraint in family ties; exactly the opposite of the natural growth trend of adolescence. Another worrying aspect is the fifth reason for distress which highlights a difficulty in defining the inner causes of the discomfort, hinting at a confusion that adolescents could not define and therefore even more difficult to master. Finally, expected aspects such as dissatisfaction related to physical appearance are typical themes of adolescence while sleep problems, issues with food and the overuse of digital devices further confirmed the adolescents’ difficulties emerged in the first part of the questionnaire.
The themes arising from the analysis of the free-text answers in our study suggest several reflections. First, we could find remarkable similarities with the results of a Korean study carried out before the pandemic [
46], on 291,110 adolescents aged 12 - 18 years, where school-related tensions were the most frequently reported reason for distress, followed by conflicts with peers and difficulties in family relationships. Also in our sample, school-related tensions were the first reason for distress followed by relationships with peers and family, demonstrating that these are fundamental issues for adolescents in our society beyond the pandemic. Moreover, the authors of the Korean study found that relational difficulties were linked to more serious consequences for psychological well-being, such as depression and suicidal risk. In our study, too, we could notice the emergence of a widespread psychological malaise which seems to be particularly associated with relational difficulties. This emerges both by reading adolescents’ own words, and from the datum highlighting that distress was significantly higher for those who reported relational difficulties as a reason for their distress (90% vs 78%).
The intensity of the experiences of discomfort and the suffering expressed in some free-text answers of the adolescents in our study, certainly exacerbated by the pandemic condition, are particularly touching and make us question ourselves regarding possible interventions.
Stress resulting from school pressure is an aspect that has been particularly studied in the last years as a determinant of mental health problems [
47]. An association between school pressure and depression, anxiety, self-harm, and suicide in the adolescent population from different countries has been recently documented in a meta analysis study [
48]. In our study school pressure was related to the sense of being overwhelmed, the fear of failing or disregarding the expectations of significant adults and the idea that psychological distress is not seen by adults, all aspects that can fuel distress and seriously threaten adolescent psychological well-being. Also the description of relationships experienced as toxic, rejecting, devaluing or extremely demanding, the sense of loneliness and relief found in self-harm or suicidal thoughts in such young children are particularly worrying aspects. We have not directly investigated distress on parenting due to the pandemic, but, in line with this result, other studies have highlighted the negative effects of parental distress on adolescents’ well-being [
49,
50].
In recent years, given the increase in youth problems at school, interventions that used the school environment as a privileged place to promote psychological well-being have multiplied and have proven effective [
51,
52]. School is the environment in which young people spend most of their time, the experiences they live there are formative and accompany them in their growth and formation of adult identity. School-based public health interventions on the prevention of emotional distress in schools have the advantage of intercepting all students and providing differentiated help according to each individual’s needs. Of particular interest are universal interventions, such as the HORS-PISTE universal anxiety prevention program [
53], which are not only aimed at students experiencing full-blown symptoms but are aimed at promoting the psychosocial skills of the entire school community, with encouraging results. The results of our study suggest looking at this type of intervention to promote well-being and actively prevent distress in adolescent students.
Some limitations of the current study should be underlined. First, the cross-sectional design did not allow to establish causal relationships between the study variables and the presence of possible psychological distress. Second, generalization of the results to Italian adolescents would be limited, considering the low response rate of students and the fact that the survey was carried out in one of the cities in the North of Italy with the highest number of days of school closure. Third, the use of self-reported data might possibly bear some inaccuracies because of recall bias related to changes in lifestyle habits compared to the pre-pandemic period. Finally, parental distress and parenting quality were not measured. Nevertheless, the results of this study are consistent with the evidence retrieved so far concerning the impact of the pandemic on the mental health of young people [
26,
54].
One of the major strengths of the study is the sample size, which was one of the largest among other Italian studies on adolescents. In addition to this, the results were supported by many free open-ended questions that allow students to better reveal their vulnerabilities and allow us to better analyze the reasons for psychological distress. Finally, the survey explored several aspects of daily life including eating habits, physical and screen activity, sleep, and smartphone addiction in relation to psychological distress providing a unique contribution to the knowledge of the long-term impact of pandemic restrictions among adolescents.
