1. Introduction
Nurses form the largest body of health care professionals in Australia and, while the nursing workforce continues to grow annually, the profession still experiences a chronic shortage of registered nurses [
1]. Alarmingly, survey data from the Australian Primary Health Care Nurses Association (APNA) showed that 86.7% of more than 1,000 of its members felt stressed at work, 78.8% felt burnt out, and 28.7% planned to leave their current job within the next 2 to 5 years [
2], leaving the long-term sustainability of the nursing profession in Australia under threat. Further, a large-scale study of more than 46,000 full-time clinical nurses in Taiwan found that perceived job stress and depressed mood were significant predictors of nurses’ intention to leave the profession [
3], indicating that the sustainability challenge extends internationally.
The advent of the COVID-19 pandemic in 2020 exacerbated the stress on nursing professionals and negatively impacted mental health globally, triggering a 25% increase in the prevalence of anxiety and depression worldwide [
4]. There is no reason to assume that nursing students, who represent a critical pipeline of new nursing professionals to sustain an adequate workforce, would be immune to such effects. Indeed, an investigation into the effects of the pandemic on the mental wellbeing of 305 final-year nursing students at three Spanish universities found that risk of mental health issues had more than doubled from pre-pandemic levels [
5]. The authors highlighted the need to prepare students for pandemic situations due to their impact “on the mental health of both the members of the public who will be treated by these future nursing professionals and the students themselves” (p. 694).
Nursing students not only have to cope with the usual stressors associated with university study, such as academic pressure, financial stress, and poor self-care [
6] but typically also experience anxiety about entering the clinical workforce [
7]. When additional stressors related to the pandemic, which have been shown to increase the risk of mental ill-health [
8] are added to the equation, coping becomes more challenging. It has even been suggested that the pandemic caused some nursing students to feel they had to choose between pursuing a nursing career and safeguarding the health of their homes and loved ones [
9].
Further, a meta-analysis of 27 cross-sectional studies [
7] showed a high prevalence of depression (34%) among nursing students generally, with younger nursing students (< 25 yr.) showing a significantly higher prevalence (41%) than their older counterparts (18%), and Asian nursing students showing the highest prevalence of depression (43%) among geographical groups. Evidence from Portugal related to the transition to professional life of senior nursing students during the pandemic [
10] showed that COVID-19 created diverse stressors ranging from “general social risks and fears of the unknown to the more concrete situations related to class interruptions that can postpone the course completion” (p. 5). However, students were equally concerned about non-pandemic issues related to applying their theoretical knowledge in professional practice contexts, particularly in areas such as safe medication administration, communication with multidisciplinary teams, and the fear of making mistakes that could harm patients. Given that nursing students are the nursing professionals of the future, the mental health of graduating nursing students is of particular interest to those concerned about the sustainability of health systems internationally [
7].
Mood profiling is a common method for monitoring mental health status in a wide variety of contexts [
11,
12,
13,
14]. Within medical settings, mood profiling has been used, for example, to monitor the psychological wellbeing of cardiac rehabilitation patients [
15] and those recovering from prostate surgery [
16]. Among nurses, mood profiling has been used previously to assess the effects of shift work on mood states [
17,
18]. Collectively, previous findings suggest that the moods of nursing students, particularly scores on the tension and depression subscales, may not only indicate risk of mental health issues but also flag risk of poorer clinical care. To assess whether the alarming rates of mental health concerns found among nurses and nursing students in other parts of the world were replicated in Australia, the primary aim of the present study was to assess mood, stress, resilience, and coping among graduating nursing students entering the profession during a global pandemic. A secondary aim was to test whether mood, stress, resilience, and coping scores varied according to the demographic characteristics of the sample. Given that mood scores have previously been shown to vary according to the gender, age, residency status, and study mode of students in the Australian higher education sector during the pandemic [
19], the group analyses in the present study included those demographic variables. Finally, employment status among graduating nursing students in Australia has been shown to be a predictor of mental health status [
20] and therefore a comparison of participants who had secured employment and those who had not was included in the analyses.
4. Discussion
Concern for the sustainability of the health system in Australia prompted this cross-sectional study of final year nursing students. The primary aim of the study was to assess mood, stress, resilience, and coping among graduating students entering the nursing profession during a global pandemic. A secondary aim was to test whether mood, stress, resilience, and coping scores varied according to the demographic characteristics of the sample.
The average mood of the graduating nursing students was more negative than population norms, with tension, fatigue, and confusion scores all significantly elevated [
13]. It should be noted, however, that the average mood of the graduating nursing students remained more positive than the typical mood reported among the general population during the height of the pandemic, using the same assessment methods [
8]. The most notable characteristic of the group mood profile was the significantly elevated levels of tension compared to population norms, which represented a moderate-to-large effect.
Although the overall negativity of mood was relatively modest, it should be noted that 22 nursing graduates (19.6%) reported mood profiles (i.e., inverse Everest and inverse iceberg) associated with elevated risk of mental health issues [
11,
12,
13,
14]. The inverse Everest profile, which is characterised by very high scores for tension, depression, anger, fatigue, and confusion, is clearly not reflective of positive mental health nor is it an optimal mood for graduating nursing students to enter the profession. The prevalence of the inverse Everest profile in the present study (8%) is higher than reported among a large sample (
N = 15,692) of the general population (4.6%)[
34], but lower than samples of the general population (12.2%)[
8] and students (9.5%)[
16] during the pandemic.
The inverse iceberg profile, which is characterised by high scores for tension, depression, anger, fatigue and confusion, and low scores for vigour, has been used for decades as signalling potential burnout among athletes [
12,
35] and is also indicative of risk of mental health issues in military [
11] and youth groups [
14]. The prevalence of the inverse iceberg profile in the present sample (11.6%) is almost identical to population norms (11.8%)[
34], and lower than COVID-specific samples (13%)[
16], (21.2%)[
8]. A further 26 nursing graduates (23.2%) reported a shark fin mood profile, characterised primarily by very high levels of fatigue and low levels of vigour. This prevalence is much higher than population norms (15.5%)[
34], and other groups assessed during COVID (15.6%)[
16], (12.9%)[
8]. The behavioural consequences of a shark fin mood profile are not well understood, although it has been linked to poor adherence to safety procedures in high-risk vocations [
36]. As such, nurses who report such high levels of fatigue may pose an elevated risk of them making medication errors, which represents a critical threat to patient safety. Fatigue among nurses has frequently been implicated as a cause of medication errors in health facilities [
37,
38,
39,
40].
A striking feature of the mood profiles was the low prevalence among the graduating nursing students of the iceberg profile, which has been associated with positive mental health and superior performance for several decades [
41,
42]. The prevalence of the iceberg profile in the present study (17.9%) was much lower than reported in the general population (28.5%)[
34] and lower even than among other COVID samples (20.2%)[
8], (20.3%)[
16]. A relatively small number of between-group differences in mood scores were found. These were restricted to higher levels of vigour reported by international students compared to domestic students, and by those still seeking employment compared to those who had already secured a job post-graduation. Previous research [
16] has shown more extensive differences in mood scores by residency status, with international students reporting higher tension, depression, anger, and confusion, as well as vigour, compared to domestic students. The greater consistency of mood scores within the current sample may be explained by the fact that they were all nursing students, whereas previous research [
16] surveyed students across a very wide range of academic disciplines. Regarding employment status, it has been shown that being employed significantly reduces the risk of mental ill-health among pre-registration nursing students [
20]. It is perhaps surprising that graduating nursing students in the present study who had not yet secured employment did not report higher scores on negative mood dimensions, nor on stress scores, compared to those who already had a job to start after graduating.
Results for perceived stress showed that the cohort of graduating nursing students in the present study reported PSS-4 scores that were high compared to the mean scores reported in the original validation study [
25] but comparable with population norms for the measure derived from a UK sample [
26]. On-campus students reported higher perceived stress than those who studied externally. This finding is consistent with a previous study of Australian students [
16], which found that on-campus students reported higher scores for depression, anger, and confusion, which was explained by “the greater flexibility afforded by online study may alleviate rather than exacerbate the stressors involved” [16, p.11]. The inverse correlation between age and perceived stress is consistent with the findings of a study that investigated generational differences in psychological wellbeing among a sample of 631 Australian pre-registration nursing students [
43], findings of which showed higher anxiety scores among the younger nurses compared to their older counterparts. Other studies of age differences on psychological wellbeing beyond the realm of nursing have shown older adults to have more highly developed skills for managing stress and to use more adaptive stress management strategies [
44].
Regarding resilience and coping, 82.1% of the graduating nursing students in the present study reported BRCS scores that placed them in the categories of medium or high resilient copers. This finding mirrors the results of a systematic review of research into resilience and coping among health care workers during the COVID-19 pandemic [
45], in which most studies showed health care workers to have high or moderate levels of psychological resilience. With respect to coping, most studies have shown high scores for positive (adaptive) rather than negative (maladaptive) coping among health care workers [
45]. Communication with family, friends, and colleagues appears to have been the primary way in which healthcare workers managed to cope with the adverse mental health consequences of the pandemic [
45]. Overall, findings from the present investigation suggest that most graduating students entering the nursing profession during the pandemic do not feel overly stressed, as assessed by the PSS-4, and tend to report positive appraisals of their psychological resilience and ability to cope with demands of the pandemic, as assessed by the BRCS. These results are encouraging for those seeking to maintain a sustainable pipeline of new graduates into the nursing profession. Nevertheless, focus should be maintained on promoting strategies to support those coming into the profession and to encourage those more experienced nurses to remain in the profession. In a study of 720 nurses conducted in Turkey during the pandemic [
46], the level of social support provided to nurses by family, friends and significant others was shown to be significantly related to nurses’ psychological resilience.
4.1. Future research
There is a need for future research to address the projected shortfall of nurses domestically [
1,
47] and globally [
3]. Bakker and colleagues [
48] conducted a systematic review of 21 studies that evaluated interventions designed to improve the mental health of student and novice nurses and/or prevent nurses leaving the profession. Interventions were focused on managing stress, facilitating the transition to nursing practice, or a combination of both. Only five studies showed a significant effect on dropout-related outcomes and generally study quality was judged to be low with a high overall risk of bias. The authors concluded that, although a wide range of interventions are available, compelling evidence of their effectiveness is limited. Therefore, for the long-term sustainability of the nursing workforce in Australia and internationally, future research should seek to develop effective ways to support nurses in training and once they are working in the profession, to prevent dropout rate.
To address this need, a systematic review of factors influencing retention among undergraduate nursing students in regional, rural, and remote areas of Australia was conducted by Liu and colleagues [
49], the findings of which emphasized the importance of academic and personal support, and highlighted several internal factors (such as stress, personal qualities, ability to engage with classes and institutions, time management, lack of confidence, cultural well-being, and Indigenous identity), and external factors (such as technical difficulties, casual tutors, different competing demands, study facilities, and financial and logistical barriers), all of which were shown to influence retention. Further research to develop evidence-based strategies to address these issues is urgently required.
A study by Grundy and Lum [
50] reported that patient expectations evolved during the pandemic, with the traditional expectations of safe, reliable, and compassionate care being augmented by an additional expectation of specific COVID-19 related safety procedures. Universities Australia has predicted a national shortfall of 85,000 nurses by 2025 [
47], requiring a significant expansion of clinical placements for nursing students, especially in the growth areas of aged care, primary care, mental health care, and disability services. Given the likely outbreaks of future pandemics, it would be prudent for student nurses to receive clinical training in pandemic-specific care as a part of their university training. University academics should consider this recommendation when designing future iterations of nursing program curricula.
4.2. Strengths and limitations
It is a strength of the present study that participation was restricted to students who were about to graduate from a nursing degree program and enter the workforce as this cohort becomes the much-needed new recruits into the nursing profession. Limitations of the present study are acknowledged. Firstly, data were collected at one university among students who participated voluntarily. Therefore, results may not generalise to graduating nursing students in other parts of Australia and beyond. Secondly, given that some of the measures used in the present study (PSS-4, BRCS) had reliability coefficients below the standard benchmark of acceptability, results related to those measures should be viewed with caution.
