students: a systematic review of quantitative studies. International Nursing Review 59, 15–25
Aim: This study aimed to identify the main sources of stress for students of nursing and the evolution of the
stressors when training in nursing competences.
Background: Levels of stress are higher for health professionals than for other workers. A higher number of
stressors with negative health consequences are present, especially among nursing professionals. Stress is a
psychosocial factor that influences the academic performance and well-being of this group. The interest in
analysing sources of stress in nursing students is due to the influence that their training period may have on
their perceptions of stress on their future work.
Methods: We conducted a systematic review of the scientific literature on stressors in nursing students. The
search comprised all the articles published at the end of 2010.
Results: The most common sources of stress relate to academics (reviews, workload and problems associated
with studying, among others). Other sources of stress include clinical sources (such as fear of unknown
situations, mistakes with patients or handling of technical equipment). In general, no changes occur at the
different years of the student’s education.
Conclusion: Comparing studies is difficult because of the differences among them (designs, instruments,
number of stressors, etc.). However, our revision gives a current state-of-the-art and includes descriptive
information that might be very useful for future research. Furthermore, we offer some recommendations for
improving the design of curricula taking into account sources of stress.

Introduction
Stress refers to a dynamic interaction between the individual and
the environment. In this interaction, demands, limitations and
opportunities related to work may be perceived as threatening to
surpass the individual’s resources and skills (Kohler et al. 2006).
In case of disarrangement, this interaction may lead to cognitive,
emotional and behavioural alterations.
Nursing students face not only academic stress but stress
at work during their training period. One focus of interest
in research on stress at work is the sources of stress, or stres-
sors, which interact and contribute to the onset of stress in
organizational settings (Spielberger & Reheiser 2005). Some of
the most common stressors are time pressures, workload,
making decisions, continuous changes and economic mistakes
at work.
In recent decades, research on health in work environments
has evolved from a focus on the prevention of physical risks
to a global approach. In this context, emergent psychosocial
risks, such as job stress, are of particular interest. Among the

negative effects of stress on the individual are physical, psy-
chological and behavioural disorders (Shirom 2003). In turn,
stress is associated with organizational-level issues, such as
increased absenteeism, decreased quality of work and decreased
productivity (Elkin & Rosch 1990).
According to various reports by occupational health institu-
tions, stress affects almost every profession. However, levels of
stress are higher, and there are a greater number of sources of
stress among health professionals, especially nurses, with nega-
tive consequences for their health (Demeuroti et al. 2000;
Humpel & Caputi 2001; Lim et al. 2010). However, the focus
should be at a stage prior to nurses’ incorporation into their
workplaces: their training period. Stress is a psychological
factor that influences the academic performance and welfare
of nursing students (Sawatzky 1998). This has led to the devel-
opment of a large body of research aimed at determining the
levels and sources of stress in the training of future nurses
(see Burnard et al. 2008; Pryjmachuk & Richards 2007b; or
Timmins & Kaliszer 2002, for a review).
Three main groups of stressors have been identified: (i) aca-
demic stressors (testing and evaluation, fear of failure in training,
problems with workload, etc.), (ii) clinical stressors (work, fear of
making mistakes, negative responses to the death or suffering of
patients, relationships with other members of the organization,
etc.), and (iii) personal/social stressors (economic problems,
imbalance between housework/schoolwork, etc.) (Pryjmachuk &
Richards 2007b).
In this paper, we present a systematic review of the studies that
quantitatively analyse the sources of stress in nursing students.
More specifically, we choose only those studies that use standard-
ized instruments for assessing the situations that cause stress
in students. Compared with other reviews, this systematic review
considers a greater number of studies.
Objectives
The aim of this paper is to identify sources of stress among nursing
students. Beyond this general objective, we analyse the specific
objective of each study. Moreover, we analyse the situation and
stressors, taking into account the academic year the students
are in. The review includes cross-sectional studies with students
from a single academic course, cross-sectional studies comparing
various academic courses and longitudinal studies that include
the evolution of the sources of stress for the same group across
different academic courses. Another specific objective is to analyse
situations and stressors directly related to the conduct of clinical
practice as part of the training of students. Finally, given that some
of the studies reviewed compare levels and sources of stress in
samples of students from different educational systems, we iden-
tify characteristically sources of stress of the educational system.
Method
This review includes quantitative studies of the factors that
nursing students perceive as stressful at the end of 2010.
Data sources and searches
MEDLINE and PsycInfo were the databases for the search.
MEDLINE is one of the most complete bibliographic databases
and includes nursing journals. We also used PsycInfo because the
stress has a psychological nature, and PsycInfo is the American
Psychology Association’s database that includes information
from different disciplines, including nursing.
The terms for the search were ‘stress’ (terms such as environ-
mental stress, occupational stress, psychological stress, social
stress, stress management, stress reaction, financial strain, physi-
ological stress, anxiety, distress, chronic stress, burnout, job
stress, work stress, etc.) and ‘nursing students’ (terms such as
nursing students, nursing education, nursery school students,
nursery school, college students, educational programs, clinical
practice, school nurses, etc.) in different combinations. The
search included articles as recent as the last week of 2010. We
established the following search limits: English-language articles
published in scientific journals with anonymous processes of
peer review that exclusively sampled humans. We conducted an
additional search based on the references included in selected
papers from the database search.
Selection criterion of the study and data extraction
The authors conducted a reading of titles and abstracts and
made the decision to include articles in the review based on the
following criteria: (i) the study included one or more instru-
ments to collect information on stress factors among nursing
students, (ii) the study included only nursing students or, if
other samples were considered, the study provided information
on nursing students separately, and (iii) the work included
quantitative information on sources of stress, excluding those
studies that only reported a global measure of stress. Articles
were included in the review if they met these three criteria.
In case of discrepancies between the researchers, discussion
meetings helped to unify the decision. Finally, papers that based
their analysis on a qualitative interpretation of the information
collected (e.g. discourse analysis, conversation analysis) were
rejected.
Results
General results
Eighty-six articles (out of 784) seemed to meet the objectives and
criteria of this systematic revision on the basis of titles and
abstracts. After the complete reading, 63 articles were discarded
16 M. Pulido-Martos et al.

for one of the following reasons: (i) samples were not exclusively
nursing students, and their results were not separated from other
students, (ii) the results only reported global scores and not
factor scores, or (iii) although the abstract did not report a quali-
tative study, it became clear upon reading the study that a quali-
tative method was used. Consequently, the final sample was
reduced to 23 studies. Table 1 summarizes the characteristics of
the selected studies.
As Table 1 reflects, in some cases, there is a discrepancy
between the size of the sample reported in the abstract and the
size reported in the sample section (sample column). Other
studies only include part of the original sample, those who com-
pleted the instrument to measure stress; in other studies, the
authors dismiss subjects in the data analysis. Although the origi-
nal sample may be larger and instruments used may measure
additional variables, we only included the sample that referred to
stress and only the sources related to stress (sources of stress
column), respectively.
In the results, terms associated with occupational settings,
such as occupational stress, job stress or workloads, among
others, are used. Obviously, these terms are placed in the
context of students’ clinical practice, understanding that in any
case students maintain any employment relationship with the
centre.
Specific results
There are many difficulties in comparing studies. The composi-
tion of the sample, the instrument used and the coding of
responses are among the factors that may impede comparison of
the results obtained in different studies. Moreover, in some cases,
the results refer to the dimensions or factors of the sources of
stress, and in other cases, the results refer to the content or
specific items of these dimensions. Thus, we report the specific
results of this systematic review on the base of the following
criteria: (i) the research objectives, (ii) the analysis of stress seg-
regated by academic courses, (iii) sources of stress associated
with clinical practice and (iv) sources of stress in terms of
curriculum.
Research objectives
Transformation of nursing curricula
A large number of the studies analyse the effects of the transfor-
mation of nursing curricula. This transformation often consists
of changing from training based on practice developed in hos-
pitals and schools to training based on university classes with a
significant increase in academic workload and a professional
curriculum. Under the Bologna process in Europe, nursing
studies have transformed to address students’ acquisition of
competencies, such as managing stressful situations.
In some of the reviewed studies, the majority of the samples
were students enrolled under the new qualifications that have a
greater academic load (Brown & Edelmann 2000; Clarke &
Ruffin 1992; Evans & Kelly 2004; Pryjmachuk & Richards
2007a,b; Thyer & Bazeley 1993). In other cases (Lindop 1999;
Rhead 1995), studies compare sources of stress perceived by
students in the traditional system with those in the new system;
Jones & Johnston (2006) in the northeast of Scotland made this
comparison. Zupiria et al. (2007) in Spain examined the innova-
tions of the new educational programmes.
In four studies, the research objective was to analyse the levels
of stress in students when the study introduced partial changes in
the form of strategies, programmes or actions to improve train-
ing. For example, the research hypothesis that guided Birch’s
(1979) study involved a lack of adequate preparation for nursing
students to address the psychological needs of patients. The
author presented the necessary restructuring of training plans to
include content specific to psychology, thus improving patient
care. Another example is Lindop’s (1991) study, which aimed to
develop a support system for the nursing staff. Both Williams
(1993) and Sheu et al. (2002) studied how nursing students effec-
tively manage stress. Specifically, Williams’ study analysed the
main concerns of nursing students on five campuses of one of
the most prestigious universities of the Western USA. Williams
proposed improving the cultural competence of the campuses to
develop support and orientation programmes for current stu-
dents and to encourage future students to contact the campus.
Sheu et al. (2002) assessed the types and levels of stress, including
physiological, psychological, and social responses, coping behav-
iours for stressful situations and the effect of coping behaviour
on physical, psychological, and social health during the initial
period of practice.
Relations of stress with other constructs
Four of the studies explored the relationship between stress and
other constructs (Basson & van der Merwe 1994; Chan et al.
2009; Edwards et al. 2010; Seyedfatemi et al. 2007). Both Seyed-
fatemi et al. (2007) at the Faculty of Nursing and Midwifery of
the Medical Sciences University of Iran and Chan et al. (2009) at
the University of Hong Kong aimed to determine the stressors
and the coping strategies nursing students employed to cope
with stressful situations. Basson & van der Merwe (1994) exam-
ined the moderating role of major life events, coping strategies
and sources of perceived stress on the effects of burnout.
Edwards et al. (2010) focused on the evolution of stress and
levels of self-esteem during the training of students. Although
the samples of some of these studies were students who were

undertaking clinical practices. Other studies analysed the rela-
tionship between the experience of clinical practices and stu-
dents’ perceived levels of stress (Admi 1997; Basso et al. 2008;
Kim 2003; and Jimenez et al. 2010).
Cross-cultural comparisons
Another group of studies has focused on cross-cultural compari-
sons. Timmins & Kaliszer (2002) conducted a review of studies
that examined the sources of stress among nursing students from
different countries and compared Ireland with those results.
They found that the most common sources are clinical environ-
ment concerning learning, academic stress, degree of stress
among nursing students and stress because of interpersonal rela-
tionships. Burnard et al. (2008) compared data from five coun-
tries (Albania, Brunei, Czech Republic, Malta and Wales) with
similar results.
General stress sources segregated by academic years
This section analyses the sources of stress reported in the studies
for the entire degree programme and for different courses.
Studies with samples from all academic years
Among the studies with representative samples of the entire
nursing degree programme are those of Burnard et al. (2008),
Pryjmachuk & Richards (2007a,b) and Seyedfatemi et al. (2007).
Pryjmachuk & Richards (2007a,b) report the situations that are
perceived as stressful: examinations/assessments, fear of failing
the course and managing financial aid. Seyedfatemi et al. (2007)
show that the most stressful situations are new friends and
working with people they did not know. Regarding intrapersonal
sources of stress, the most frequently selected were new respon-
sibilities and starting college. With regard to academic stress,
increased class workload was most frequently selected and as for
the most stressful environment stressors, being placed in unfa-
miliar situations and waiting in long lines were the most selected
in this order.
In a longitudinal and cross-cultural study, Burnard et al.’s
(2008) study yielded heterogeneous results depending on the
country. Specifically, academic aspects stressed students in
Brunei and Malta whereas clinical aspects stressed students in the
Czech Republic and Albania (Tirana). Finally, there were no
differences between academic and clinical aspects in Wales.
Clarke & Ruffin’s (1992), Thyer & Bazeley’s (1993) and
Williams’ (1993) analyses focused on new students in nursing.
Williams (1993), used only descriptive statistics to analyse the
items in a disaggregated way. The students showed the highest
concern for keeping their grades up, fear of making a mistake

with a patient and learning clinical procedures. Thyer & Bazeley
(1993) studied first semester Australian students and the areas
in which students experienced higher levels of anxiety corre-
sponded with the assessment of work throughout the course
and the return of assignments.
Also in Australia, Clarke & Ruffin (1992) collected data on
students enrolled in the first year of nursing at three different
centres (university, advanced education and hospital). The most
stressful situations were the total amount of work to be com-
pleted, coping with exams and handling emergencies. When
taking into account the factors, the emotional demands of
nursing and the use of technical equipment were the most
stressful.
Basson & van der Merwe (1994) analysed the sources of stress
among a sample of students in the second and third year (of a
four-year programme) who were carrying out their practice in a
hospital in Natal (South Africa). The following six items had the
highest mean scores: having to write academic or practical
exams; the extent to which working hours influenced the possi-
bility of a fulfilling social life; having to act with accuracy in crisis
or emergency conditions; the extent to which students were
exposed to demands that exceeded their knowledge and ability;
the extent to which shift work affected moods, and social and
home life; and exposure to potentially dangerous and contagious
diseases, such as AIDS.
Two of the studies focused on stressors for nursing students
who were finishing their studies (Evans & Kelly 2004; Timmins &
Kaliszer 2002). Evans & Kelly (2004), using Lindop’s (1989, 1999)
instrument with a sample of third year students at a university
hospital in Dublin, found the items with the highest scores for
educational factors were exams, an intense amount of work,
difficulty of academic work and studying. Among the clinical
factors, the situations that generated the highest levels of stress
were differences between the ideal practice learned in school and
real situations in the healthcare environment, aloofness from
more senior staff and an unfriendly environment in hospital
wards, being reprimanded in front of staff and patients, and
being left for short periods on the ward without trained nurses
present. Timmins & Kaliszer (2002) also studied third year stu-
dents. Factors causing stress were those associated with academic
performance, specifically clinical placements, financial con-
straints, the death of a patient and relationships with the staff in
the wards.
Evolution of sources of stress over training
Compared with the transversal studies mentioned above, longi-
tudinal studies allow reliable comparisons about the stressors
and about the situations included in the items. These data offer
methodological safeguards and an analysis of the evolution of
the stressors. Thus, Jones & Johnston (2006) analysed the evolu-
tion of stressors in a group of nursing students in two educa-
tional systems. They concluded that the sources of stress were
unchanged with time. When considering weeks 24/25 and 40/50
of their training, sources of stress with higher scores included
academic load followed by interface concerns, clinical concerns
and personal problems. Brown & Edelmann (2000) yielded
similar conclusions about the stability of the sources of stress by
comparing a group of freshmen with a group that accumulated
18 months of training.
Edwards et al.’s (2010) study provide information on sources
of stress at five different times over the first three training
courses. Although they found significant differences in general
stress levels by course, they did not report the differences for the
factors (academic stress and clinical stress). However, analysing
the order of the items mean scores for the five times suggests that
the most intense sources of stress remained stable throughout
the training.
In a cross-sectional study, Lindop (1991) reported differences
in stressors by academic year. The students agreed on the stres-
sors related to education. However, when analyzing specific situ-
ations such as taking exams or the amount of work, the students
at higher levels (second and third years) experienced higher
levels of stress. There was also general agreement about stressful
experiences in the clinical context but were more intense in the
last years of the programme.
Sources of stress associated with clinical practice
Because clinical practice is important for future professionals to
acquire competence, a group of studies has focused exclusively
on the analysis of these activities as sources of stress. The studies
included here focus on academic and social stressors arising from
work experience in health centres because of conducting clinical
practices.
Three cross-sectional studies examined the nature of stressors
without regard to academic course and without analysing the
evolution of these stressors (Chan et al. 2009; Kim 2003; Sheu
et al. 2002). Sheu et al. (2002) find that the most common stres-
sors were related to the lack of knowledge and professional abili-
ties followed by taking care of patients. The specific items related
to these most stressful situations were lack of experience and
ability to provide nursing care and diagnostics, lack of familiarity
with history and medical terms, and concern about poor grades.
Using a similar sample of nursing students and the same
instrument, Chan et al. (2009) report that the most common
type of stressor among students was a lack of knowledge and
professional skills, followed by the stress of the tasks and work-
load. The third most common stressor proved to be the stress
resulting from patient care.
Systematic review of sources of stress 21

In Kim’s (2003) study, clinical situations that caused higher
levels of anxiety in the students were being late, being observed
by instructors, fear of making mistakes, initial clinical experience
on a unit and talking with physicians.
Only two studies have compared different academic courses
regarding the sources of stress associated with clinical practice,
specifically, Basso et al. (2008) and Jimenez et al. (2010). Basso
et al. (2008) compared students in the second and third years
(out of 5 years, or ten semesters). Items for the competence factor
with the highest frequencies were, in this order, making a mistake
in work and harming the patient, being in a situation where the
student does not know what to do, and confusing the treatment.
Teaching factor was more important for third year than second
year students. The items for this factor yielding highest frequen-
cies were receiving contradictory orders from teachers, a tutor
that reprimands the student in front of patients and hospital
staff, and receiving extra work activities from the teacher in
charge of the laboratories, such as connecting the number of
patients assigned and the daily operations.
In Jimenez et al.’s (2010) study, the differences by academic
year were in two first-order factors. Stress from assignments and
workload, a clinical stressor, was perceived with greater intensity
by second year students than first year students. First year stu-
dents perceived academic factor more intensively than the other
groups. For second-order factors (clinic, academics and external
stressors), the unique differences were among the academic
sources, which were perceived with greater intensity by the first
year compared with the second and third year students.
In longitudinal studies that allow comparison between aca-
demic years (Birch 1979, Admi 1997; Zupiria et al. 2007), there
are no significant differences between the types of stressors in
different levels of the degree programme. Although Admi (1997)
presents different results about the types of sources listed, this
study also reports on the stability of the sources by academic
year. Birch’s (1979) study participants were students from four
nursing schools in Northern England. They completed an ad hoc
instrument at two different times (8 and 24 months after the
beginning of the training period). Although the analysis of the
scores for the items shows no significant differences on the two
occasions, a detailed analysis shows that as training progresses,
the sources of stress that become more important are those
related to behavioural aspects, while the importance of admin-
istrative aspects diminishes.
Sources of stress in terms of curriculum
With the shift in nursing education to higher education and the
significant increase in course load in the curriculum of future
professionals, two studies (Lindop 1999; Rhead 1995) have
explicitly compared traditional and new curricula. Rhead (1995)
compared the intensity of stress perceived by nursing students
from two schools in Southwest England. The questionnaire was
completed by a group of students from the traditional system
[Registered General Nurse (RGN)], based on practical profile
programmes, and a group from the new system (Diploma of
Higher Education in Nursing), based on a more academic pro-
gramme. In the traditional system, the students experienced
more stress from the practical aspects of their training. The
group in the new system did not differ in the intensity of
the academic and practical stressors. Similarly, Lindop (1999),
following the same procedure as in a previous study (Lindop
1991), compared students from both systems: the traditional
(certificate-level training leading to RGN) and a new system
(Project 2000 diploma-level training, Adult Branch). The former
is practice oriented and the latter is academic oriented. The
intense amount of work and the tests were identified as stressors
related to the educational environment in both groups, and the
amount of work was more stressful for students in the new
system.
Discussion
From this systematic review, we can conclude that most of the
studies took place in Europe, and more than one-fourth of these
studies about stress in nursing students were conducted in
England. There are data from samples of students from all
continents, although they are found in isolated studies. While
30% of studies were longitudinal, 70% of the studies were of a
cross-sectional design.
With regard to sample size, the high dispersion should be
noted; the range extends from 46 to 1707 students. The mean is
326, which is not a representative value. The median is 205, and
the 75th percentile was at 366. However, most studies sample size
was smaller than this.
There is great variability regarding the instruments used. Eight
of the studies designed ad hoc instruments to measure stress.
Only three instruments were used in more than one study,
although in some cases, modifications were introduced. Thus,
Lindop’s (1991) scale was modified by Lindop (1999) and by
Evans & Kelly (2004). The Perceived Stress Scale by Sheu et al.
(1997) was used by three of the reviewed studies (Chan et al.
2009; Jimenez et al. 2010; Sheu et al. 2002). The Student Nurse
Stress Index by Jones & Johnston (1999) was used by them in a
subsequent study (Jones & Johnston 2006) and by Pryjmachuk &
Richards (2007b). The KEZKAZ by Zupiria et al. (2003) was also
used in two other studies (Basso et al. 2008; Zupiria et al. 2007),
and the Stress in Nurse Education questionnaire by Rhead
(1995) was used by Burnard et al. (2008) and Edwards et al.
(2010). In the remaining ten studies, the instruments were
different.

This variability is also present in the content and structure of
the instruments. In the studies reported, instruments included
12–144 items, all with the purpose of assessing sources of stress
in nursing students. The factors identified ranged from two to
nine, indicating heterogeneity in the content when evaluating
stress.
Two of the studies used instruments that were not specific to
assessing stress in nursing students (Basson & van der Merwe
1994; Thyer & Bazeley 1993). The content of the items in Thyer
& Bazeley’s (1993) study related to academic aspects, whereas
Basson & van der Merwe’s (1994) study referred to the clinical
context in which the practice was conducted. The sources of
academic and clinical stress were considered jointly in most of
the studies reviewed (Burnard et al. 2008; Chan et al. 2009;
Clarke & Ruffin 1992; Edwards et al. 2010; Evans & Kelly 2004;
Jones & Johnston 2006; Lindop 1991, 1999; Pryjmachuk &
Richards 2007b; Rhead 1995; Seyedfatemi et al. 2007; Sheu et al.
2002; Timmins & Kaliszer 2002; Williams 1993). Other studies
specifically assessed the sources of stress related to clinical
practice: Admi (1997), Brown & Edelmann (2000), Kim (2003),
Zupiria et al. (2007), Basso et al. (2008) and Jimenez et al.
(2010). The following studies focused on additional sources of
stress among nursing students, such as social relations (Chan
et al. 2009; Clarke & Ruffin 1992; Jones & Johnston 2006; Pryj-
machuk & Richards 2007b; Seyedfatemi et al. 2007; Sheu et al.
2002; Williams 1993), general personal problems (Chan et al.
2009; Jones & Johnston 2006; Pryjmachuk & Richards 2007b;
Seyedfatemi et al. 2007; Sheu et al. 2002), family issues (Clarke &
Ruffin 1992; Williams 1993), economic issues (Timmins &
Kaliszer 2002; Williams 1993) or loneliness (Williams 1993).
The large number of stressors makes it difficult to compare
results between studies; however, the grouping of sources in the
results in this review may be useful for future work. Researchers
may choose to assess sources of stress according to academic,
clinical or social areas.
The research objectives in the studies reviewed highlight the
importance of transforming the curriculum and introducing
new programmes and how these changes may adversely affect
students. Almost half of the studies were designed to examine the
aspects of nursing students’ training that were perceived as
threatening and to determine whether they remain with the
transformation of the curriculum. Other variables are taken into
account, such as coping strategies used by students and the rela-
tionship between constructs such as stress and burnout or self-
esteem. Other studies examined the importance of clinical
practice in the training of future nurses and how participation
can lead to perceptions of stress. In the context of globalization,
the results derived from studies focused on cross-cultural stress
in nursing students are very useful.
Most of the studies found no significant changes in students’
perceptions of the factors that lead to stress in different stages of
training (Brown & Edelmann 2000; Edwards et al. 2010; Jones &
Johnston 2006). Only Lindop’s (1991) research reported on
changes in the upper grades (second year and third year vs. first
year). Students in the upper grades suffer from more stress
related to academic and clinical sources. The factors that ulti-
mately lead to stress are related to a greater extent to the aca-
demic world. The items or dimensions occupying the top
positions among the concerns of students are evaluations or
examinations, the fear of failure, an excessive workload, main-
taining grades and study skills.
Implications for practice
In agreement with Timmins & Kaliszer (2002), those responsible
for the programmes should consider the time spent by students
on the proposed tasks to avoid work overload. Furthermore,
alternative forms of assessment beyond the acquisition of skills
for testing, such as learning-oriented assessment (Carless et al.
2006), could help to reduce academic stress among students and
the reduction of negative psychological symptoms (Deary et al.
2003). Clinical sources that were identified as most stressful
include dealing with unfamiliar situations, making errors with
patients, learning to apply clinical procedures and managing
technical instruments, among others. Following McVicar’s
(2003) proposal, students should understand that the perceived
lack of competence to deal with these situations disappears with
further practice. Therefore, the practical period must be under-
stood as an opportunity to learn more than as a stage of
evaluation and testing of theoretical knowledge.
Conclusion
Comparing studies was difficult due to the methodological dif-
ferences between them. However, our revision gives a current
state-of-the-art and descriptive information that might be very
useful for future research. We point out the importance of edu-
cators and clinical facilitators to be sensitive of these stressors
and provide students with effective coping strategies to deal with
the inevitable sources of stress present during nurse education
and training. These strategies may lead to the reduction of nega-
tive psychological symptoms associated with perceptions of
stress. Future research should consider reviewing papers that
have used qualitative methodologies to contribute information
to this work.
