1. Introduction
During the last two and a half years, pandemic restrictions almost halted the world. Social interactions were heavily reduced, and lockdowns, quarantines, and physical distancing measures were put in place. This situation might have contributed to many people’s stress and mental health problems [
1]. It also included substantial limitations on the functioning of schools. The survey of 122 UNICEF countries in early March 2022 shows that schools have been closed for 20 weeks and partially closed for an additional 21 weeks [
2]. According to UNESCO’s Global Monitoring of School Closures, one in ten countries closed their schools entirely for over 40 weeks [
3]. School lockdowns were among the primary prevention measures during the pandemic [
4]. When the COVID-19 epidemic appeared in Poland, 23,600 schools (including 14,400 primary schools and 9200 secondary schools) were attended by a total of 4.8 million children and youth (2019/2020 school year). In the 2020/2021 school year, there were 4.9 million students in the education system. After the state of the epidemic was announced on 20 March 2020, the education of children and young people in schools in the school years 2019/2020 and 2020/2021 was organised by ad hoc changes to the educational regulations (remote, or hybrid system). The Minister of Education and Science, in cooperation with the Minister of Health, the Chief Sanitary Inspector, and school superintendents, took steps to create legal and organisational conditions that would enable schools to function in the event of a COVID-19 threat [
5].
The COVID-19 pandemic has been a traumatic experience for many people worldwide, especially those infected or susceptible to the infection. The adverse impact of the COVID-19 pandemic is relatively unknown [
6,
7]. Due to school closures, remote learning, and social isolation, children and adolescents experience loneliness, anxiety, and stress [
8,
9,
10,
11]. Simultaneously, special attention has been paid to pupils’ psychological well-being during COVID-19, while less consideration has been devoted to other members of the school community [
12]. This holds especially true for school principals who are responsible for general school matters and who faced many challenges during the pandemic.
School principals coped with numerous significant challenges regarding school management during the epidemiological crisis [
4,
13]. They were responsible for implementing policy measures such as organising remote or hybrid learning, adjusting school work to the national and epidemiological requirements, ensuring continuity of education and supporting programmes for students after schools reopened, and ensuring hygiene measures for schools and a safe educational environment [
1,
14]. The social distancing of teachers and pupils also resulted in additional work and pressure due to the considerable responsibility of school principals. They had to adjust their decisions to the procedures and protocols of the education authorities, which often changed overnight due to the epidemiological situation [
15]. School principals had to deal with “managing and coordinating activities of education authorities, teacher, students, and their parents, and to improve student’s performances and teacher’s satisfaction” [
15]. All these tasks were much more demanding, considering that there were only limited guides and precedents for managing schools during the pandemic [
15]. However, it is worth emphasizing that the Polish Supreme Audit Office positively assesses the activities of the directors of Polish schools, who, despite frequent and urgent changes resulting from the developing epidemic situation, ensured the proper organization and implementation of didactic, educational, and care tasks. Nevertheless, the lack of a systemic approach to the functioning of Polish schools during the epidemic and the related failure to define teaching standards by the Minister was a source of stress for all members of school communities [
5].
School principals worldwide work under tremendous pressure since they face many demands starting with filling administrative and management functions such as scheduling, reporting, resolving conflicts, and cooperating with parents and community stakeholders. Another of the school leaders’ tasks is increasing learner achievements, maintaining the satisfaction of teachers, and creating a positive school climate. Motivating teachers and pupils and managing resources effectively to enhance the best educational practices are also essential in the daily work of school principals. Unexpected situations and great crises in the workplace are also their responsibility [
16]. The work demands and new conditions of operating faced by school principals during the coronavirus pandemic were, for many, a source of work-related stress [
1]. For example, according to the United States nationally representative survey of the well-being of secondary principals (1686 secondary principals) one year after the start of the COVID-19 pandemic, 83% of principals reported experiencing frequent work-related stress during the 2020–2021 school year and this affected women more than men [
17]. Fotheringham et al. also surveyed the pressures and influences of the pandemic on school principals during the COVID-19 crisis. Their research revealed that 35% of the participants indicated frequent changes in information were the most problematic. Other challenges, such as a lack of time and clarity of the information received, caused many school principals to perceive difficulties as stressors [
18]. Moreover, the awareness of the importance of their role in maintaining the teaching and learning processes at school and the risk of becoming infected could cause fear about their health. The survey conducted by Van Duong et al. proved that symptoms that suggested coronavirus infection raised Taiwan school principals’ concerns about their health and ability to accomplish work [
19]. Consequently, those respondents may have experienced more pressure and stress, leading to mental health disorders and burnout. Other results from research conducted among female school principals across Finland revealed that work burnout, workload, COVID-19-related concerns, and difficulty detaching themselves from work are related to the high-stress profile of school principals [
1]. Similarly, findings from semi-structured interviews with Norwegian school principals confirmed that increased work demands and the overtime associated with the transformation to remote schooling and the entire digitised educational situation were significant stress factors for both themselves and their staff [
20]. Occupational stress during COVID-19 was a result not only for school principals but also for teachers. For example, a study conducted in Ireland revealed moderate or high levels of work burnout for 79% of teachers. The adverse effects of working during the pandemic were reported by teachers in the areas of physical (43%) and mental health (67%), with deterioration in eating (34%), sleeping (70%), and alcohol use (33%) [
21]. Simultaneously, many Portuguese teachers reported symptoms of stress, anxiety, and depression [
22]. The source of teachers’ burnout was pandemic anxiety and a lack of administrative assistance [
23].
Among the different stress conceptualisations, models, and scales [
24,
25,
26,
27,
28], the transactional concept of stress by Lazarus [
29] is the most useful for this study. According to this theory, environmental influences themselves are not stressors. However, they become stressors when an individual perceives them as threats and as something that exceeds the individual’s capacity to deal with [
30,
31]. Similarly, occupational stress is often a consequence of the mismatch between work resources and what is required (the demands-resources [JD-R] model) [
32,
33,
34]. In this context, resources refer to work conditions within which individual characteristics can be used to attain organisational goals (e.g., control at work and social support; personal resources are self-efficacy, locus of control, skills, and stress coping styles). At the same time, from the standpoint of the job strain model, the most significant risk to physical and mental health disturbances caused by stress occurs to workers facing high psychological workload, demands, or pressures together with low control in meeting those demands [
30]. One of the main indicators of the work-related health deterioration process is burnout syndrome [
35]. This is defined as “a work-related state of exhaustion that occurs among employees, which is characterised by extreme tiredness, reduced ability to regulate cognitive and emotional processes, and mental distancing. These four core dimensions of burnout are accompanied by depressed mood as well as by non-specific psychological and psychosomatic complaints” [
36]. Maslach and Jackson defined the physical and psychological symptoms of burnout and pointed out the loss of self-esteem, depression, alcohol abuse, and exhaustion [
37]. Considering that school principals have numerous tasks and occupational responsibilities that might result in high work-related stress, special attention should be paid to this occupational group. As Dadaczynski and Paulus [
38] indicated, in comparison to physical health problems, school principals more frequently suffer from mental health problems such as psychosomatic complaints, anxiety, depression, or symptoms of burnout. At the same time, the cited authors pointed out that school principals have been neglected in school health promotion. Meanwhile, it affects all members of a school community, influencing the implementation and overall success of health-promoting activities in the school.
This study examines respondents’ perceived stress and its association with two chosen burnout indicators using quantitative survey methods. We consider perceived helplessness and self-efficacy (two Perceived Stress Scale [PSS-10] subscales) as independent variables potentially associated with school principals’ mental and physical functioning. The COVID-19 pandemic influenced people’s lives, generating a lot of insecurity, anxiety, and fear [
39]. Schools worldwide were among the most affected settings [
40,
41,
42], causing school principals to act under unrelenting pressure with limited space to manoeuvre [
15]. We assumed this pressure in an already demanding job increased school principals’ likelihood of stress, health problems [
43], and risk of burnout. The burnout indicators were: exhaustion and psychosomatic complaints (dependent variables). Emotional exhaustion related to work situations is a significant dimension of burnout that is understood as a consequence of long-term occupational stress [
44]. We are aware that the relationship between dependent and independent variables in our regression models could be bidirectional, as many studies have reported the association between exhaustion and work stress [
45]. For example, Lau et al. suggested that exhaustion related to work situations could be a predictor of teachers’ perceived stress [
46]. In our analysis, principals’ gender and age were introduced as sociodemographic control variables assuming that men and women differ in their perceptions of stress factors [
47]. Our findings increase understanding of Polish school principals’ stress levels, mental and physical well-being during the pandemic, and as a result, the potential risk of burnout. Although a large proportion of pandemic research on educational settings was conducted in Poland, its focus is mainly on pupils, teachers, and parents’ opinions concerning remote learning during the coronavirus pandemic [
48,
49,
50]. This is the first community-wide study to examine Polish school principals’ perceived stress levels and their relation to burnout indicators in the middle phase of COVID-19 (June–December 2021). However, it is worth emphasising that some relevant studies have been conducted in other parts of the world concerning school principals’ work during the coronavirus pandemic [
19,
46,
51,
52,
53,
54].
4. Discussion
The pandemic has altered the nature of school principals’ work. They had to extend their roles to create safe educational settings, provide tools and support for virtual teaching, and answer the school community’s concerns and worries [
68]. The unexpected and radical changes in working conditions set new expectations and role requirements for principals, many of whom experienced the pandemic as a significant stress [
20]. Therefore, this article presents empirical evidence for perceived stress among school principals in Poland (concerning the PH and PSE subscales), its association with mental and physical exhaustion, and psychosomatic complaints (as burnout indicators) during COVID-19. It has been proved that stress negatively affects mental health [
37], and helplessness is perceived as an essential component of psychopathological symptoms [
61]. In contrast, self-efficacy is a factor that alleviates the effects of stressors on psychological functioning. Moreover, assuming that men and women differ in their perceptions of stress factors [
47] and that age is a relevant analytical dimension since it involves diverse expectations and obligations for individuals within the life course [
69], in this study, these sociodemographic factors were included as control variables. Additionally, one of the primary goals of the presented research was to assess the burnout risk of Polish school principals potentially caused by working during the demanding and challenging times of COVID-19.
The results obtained proved that almost half of the surveyed school principals often felt nervous and stressed at work (48.5%) and were upset due to unexpected events at school (47.4%). Over 40% of Polish school principals experienced a lack of control that caused anger and stress. Our findings align with research outcomes already mentioned [
1,
19,
20,
21,
22], confirming the high-stress level of school principals during the pandemic.
School principal self-efficacy has been defined as the principal’s perception of their capacity to fulfil the cognitive and behavioural functions required to arrange the group processes to achieve the school’s goals [
70]. Concerning the results presented in this paper, more than half of the surveyed principals manifested a high level of self-efficacy during the COVID-19 pandemic. Overall, school principals in Poland more often indicated self-efficacy than helplessness. We assume they had particular resources (e.g., social support; more decision latitude, and higher salary compared to teachers) that helped them work during the health crisis with conviction about their ability to manage their school efficiently [
1]. The statistical analysis also revealed that the increase in Polish school principals’ self-efficacy was related to a decrease in physical and mental exhaustion. We assume that the respondents’ high self-efficacy influenced their adaptation strategies and ability to cope during the pandemic [
71]. However, the association between PSE and physical and mental exhaustion was weaker compared to PH. At the same time, there was no association between perceived self-efficacy and psychosomatic complaints. A strong sense of self-efficacy is crucial for school principals as they are more determined to achieve their goals, more flexible, willing to adapt to changing situations [
72,
73] and manage better in high-demand and high-control conditions [
74]. In contrast, principals with a weak sense of self-efficacy are reported to prefer extrinsic or institutional power, experience more anxiety and stress [
75], and suffer physical exhaustion and a sense of despair. The level of self-efficacy is one of the more critical issues for school principals, as burnout symptoms are associated with this factor [
37].
In the presented study, the regression analysis revealed that Polish school principals’ PH was associated with their physical and mental exhaustion and psychosomatic complaints. Simultaneously, it must be emphasised that helplessness was a stronger predictor for exhaustion than psychosomatic complaints. These findings are consistent with the study of Gmelch and Gates [
76], who concluded that there are moderate to high correlations between principals’ emotional exhaustion and stress levels (of which helplessness could be one of the dimensions [
47]). Moreover, according to Kirchner et al.’s [
77] research results, subjectively PH was a significant predictor for posttraumatic symptom severity (PTSS). The result obtained is also crucial for the risk of burnout, as exhaustion is the core symptom of burnout [
57]. Simultaneously, the stressful work conditions of school principals during COVID-19 were potentially detrimental to their health conditions [
78]. Many surveys have proven the relationship between work-related stress and physical health [
78,
79,
80], often manifested by psychosomatic symptoms and negatively influencing an individual’s quality of life. Long-term health outcomes can result in many days off and early retirement due to psychosomatic illness [
38,
81].
Analysis stratified by gender indicates that the associations found seem more important for female principals. The higher level of self-efficacy among women was related to lower mental and physical exhaustion. In addition, woman’s age differentiated the perception of exhaustion and psychosomatic complaints. Their mental and physical exhaustion and psychosomatic complaints decreased with age. Our explanation for the results obtained is that older female principals have a lower likelihood of role conflict between professional and nonprofessional roles. Sociological research shows that women generally experience more difficulties in the reconciliation of work and family than men [
69]. With reference to the results obtained, it is worth recalling that in the studies about working and living conditions among local politicians in Sweden and their experiences with combining political work and family life, work-family conflict is highest among the youngest age groups, especially women [
69]. Additionally, women still do unpaid work in the home and care for children and relatives, even when they work full-time. This generates a lot of pressure since they cannot possibly reconcile work and family life [
47]. Considering the results obtained, we also assume that older female principals were more experienced, which might influence their perception of the unprecedented situation of the pandemic. As a result of their occupational experience, older women may have had a greater sense of self-efficacy [
45], through which they felt less mentally and physically exhausted and, thus, less likely to experience psychosomatic complaints. The significance of the professional experience of school principals was confirmed by some research suggesting that the knowledge gained is crucial for a realistic approach to the problems at school [
82], overcoming challenges and consequently enhancing their sense of self-efficacy [
83]. These findings are also consistent with the Van Duong et al. study [
19], showing that older age was associated with a lower likelihood of depressive symptoms. The cited authors similarly explain that older principals may have more experience in managing and solving work difficulties [
19]. Simultaneously, special attention must be paid to younger female principals who were more often mentally and physically exhausted and experienced more psychosomatic complaints.
Identifying feelings of helplessness, mental and physical exhaustion, and psychosomatic complaints among Polish school principals during the pandemic (especially younger females) is essential since these can lead to long-term sickness absences [
84], burnout, early retirement, or resignation from their positions. This is particularly important in the Polish educational system, given the increasing problem regarding job vacancies for school principals, the resignation of the principal’s functions, earlier retirement, or disability pension [
85,
86,
87]. The pandemic experiences probably exacerbated this trend. According to the US National Association of Secondary School Principals survey, pandemic working conditions accelerated plans to leave the profession for 45% of the surveyed principals in August 2020 [
88]. Thus, there is an urgent need to understand principals’ work-related stressors and identify how policymakers and other stakeholders can support principals’ well-being and improve job performance and retention [
17].
In the face of the results obtained, we recommend national policymakers and local leaders consider school principals’ well-being and take actions to mitigate work-related stressors, supporting their health and preventing burnout [
17]. Work-related stress can be prevented and managed through individual and organisational strategies [
89]. These interventions may increase job satisfaction, well-being, autonomy, and perceived stress at the personal level. At the corporate level, these interventions may improve absence rates due to sickness [
90]. It is also crucial to focus on the resources which refer to work conditions, such as control at work and social support, and personal resources such as self–efficacy, locus of control, skills, and stress coping styles [
30]. To reduce school principals’ stress and workload, sharing some of the principals’ job responsibilities with co-workers or an administrative team would be supportive. Promoting collegiality and collaboration in principals’ work would help create social capital, supporting principals’ well-being [
91]. Coaching and mentoring may also provide social support, help principals feel less isolated, and mitigate the overload school principals may experience during a crisis [
75,
76]. On the individual level, mindfulness sessions could be a recommended solution to support school professionals in managing and reducing work-related stress. The literature shows mindfulness training decreases occupational stress and burnout [
92,
93,
94,
95]. The concept of stress management, defined as the human ability to cope with stressful events and situations, may also be effective in raising school principals’ psychological resilience [
96]. Revealing a salutogenic leadership style [
97] should also be considered as one of the solutions for supporting and enhancing school principals. The salutogenic leadership style is understood as “the ability to promote teachers’ sense of comprehensibility, manageability, and meaningfulness” [
38]. Furthermore, social support, which seems to have a substantial stress preventive effect, especially for women [
47], should be an essential factor in limiting the negative impact of job demands [
1,
34,
91] and treated as one way of preventing burnout.
The presented research results should be interpreted with some significant limitations. Firstly, it was a cross-sectional study conducted in the middle of the pandemic (June–December 2021). After the first pandemic “shock” (in the spring of 2020), it is highly probable that school principals acquired new skills and adapted better to the situation. This could have caused a decrease in principals’ stress. It is also not feasible to prove a direct connection between school principals’ working in pandemic conditions and their health. One of the reasons is that it is difficult to assess the long-term health effects caused by experiencing work-related stress, which can also be related to individual lifestyles or coping behaviours [
19]. Moreover, the cognitive appraisal of stress and the assessment of workload are very subjective and depend on individuals’ features, for example, problem-solving style [
98] or type of behavior pattern [
99]. Therefore, it is crucial to examine the multiple demands, resources, and well-being indicators associated with principals’ stress profiles in a further study [
78]. Nevertheless, the presented research could be the baseline and starting point for creating mental health promotion and burnout prevention strategies for school principals, whose health and well-being are crucial for effectively managing schools, especially during unexpected crises.
