Introduction
Bullying is a specific form of interpersonal aggression or targeted harassment, often distinguished by an imbalance of power between a perpetrator and a victim. This category of behavior can include various subtypes such as abuse, incivility, and harassment, as well as more specialized forms like mobbing, horizontal violence, and lateral violence [
1,
2]. These subtypes are not merely synonyms but represent distinct manifestations of bullying, each with its own characteristics and impact [
3]. Recent research suggests that nursing students are particularly vulnerable to bullying due to the hierarchical nature of their work environment. This vulnerability is heightened for new graduates who are navigating unfamiliar settings or possess limited clinical experience [
4,
5]. Despite the frequency of bullying incidents reported by nurses, it is widely believed that the actual prevalence significantly underreported [
6‐
8]. Interestingly, some nursing students suggest they expect to encounter bullying in the profession [
9,
10]. However, there is concern that these students may come to normalize bullying and inadvertently perpetuate it in the future [
11].
A significant number of nursing students worldwide report experiencing bullying. For instance, over half of Turkish nursing students indicated encountering at least one form of bullying on a weekly basis over the past six months [
12]. Similarly, 40% of nursing students in New Zealand reported being bullied during their clinical placements [
13]. Bullying occurs in various forms and settings, involving both students and faculty in academic and clinical environments [
14,
15]. The most frequently reported types of bullying during training include verbal abuse, discourteous behavior, and intimidation [
12,
16]. Prior research suggests that bullying between nurses and students is more prevalent than in any other professional relationship within nursing, with teacher-to-student bullying considered the most severe [
3]. Cooper et al. identified three core bullying behaviors commonly reported by nursing students: assignments or tasks given as punishment rather than for educational purposes, punitive grading, and the imposition of unmanageable workloads or unrealistic deadlines [
16]. The repercussions of such bullying are severe; students undergoing clinical placements have reported experiencing anxiety, panic attacks, physical discomfort, and a significant loss of confidence and self-esteem [
17]. Based on the results of a review study conducted on bullying in nursing students, classmates, professors, instructors, and hospital nurses have been reported as the sources of bullying behaviors [
18].
A work environment perceived as unsafe can have far-reaching consequences, including contributing to nursing shortages, compromising patient care, and limiting educational opportunities for nursing students [
3]. Empirical evidence suggests that the prevalence of bullying within the profession can lead nurses to exit the field, thereby exacerbating existing shortages and straining healthcare systems. Moreover, the psychological toll of bullying—manifested in stress, anxiety, and diminished self-esteem—can adversely affect patient care by fostering a lack of empathy and reducing the overall quality of care provided [
9].
Methods
Study design
This research employed a cross-sectional study design to explore the relationships among bullying behaviors in nursing educational settings, sense of belonging, major satisfaction, and intentions to drop out. The study focused on undergraduate nursing students from Alborz and Mazandaran Medical Sciences Universities. Data were collected through an online survey hosted on the Porsline platform (
https://porsline.ir/) from April to June 2023.
A link to the survey, accompanied by a concise description of the study’s objectives, was disseminated via various social media applications, including Telegram, What’s App, and Persian applications. Participants had the flexibility to respond using smartphones, tablets, or laptops. To validate if the actual students answered the survey link, we sent questionnaire link into university official channels.
Inclusion and exclusion criteria
Eligible participants had to meet the following criteria: (1) Be undergraduate nursing students enrolled at Alborz or Mazandaran Medical Sciences Universities who had completed at least one semester; (2) Express willingness to participate in the study; and (3) Not be concurrently employed as nursing staff.
Students who declined to participate or who failed to complete the survey in its entirety were excluded from the study.
Participants
Based on the study’s design, which included four latent variables and 66 observed variables, a minimum sample size of 382 was required. This calculation assumed a significance level of less than 0.05, a power level of 0.8, and a small effect size of 0.2, as defined by Bakker et al. (2019) and Leppink, O’Sullivan, & Winston (2016). To account for potential dropouts or incomplete responses, a total of 400 undergraduate nursing students from Alborz and Mazandaran Medical Sciences Universities were recruited for the study. Participants were selected using a convenience sampling technique.
To validate if the actual students answered the survey link, we implemented the following strategies:
-
Confidentiality and Anonymity: To ensure the privacy of participants, the survey was designed to be anonymous, and no identifying information was collected. This approach encouraged students to provide honest responses without fear of repercussions.
-
Distribution through Official Channels: The survey link was shared with nursing students through official channels, such as university email systems or learning management platforms. This helped to ensure that the survey reached the intended participants and minimized the risk of unauthorized access.
-
Monitoring and Quality Control: We closely monitored the survey responses to identify any potential issues, such as multiple submissions from the same individual or responses that did not align with the study’s objectives. In such cases, we took appropriate measures, such as removing duplicate or irrelevant responses, to maintain the integrity of the data.
Measurements
a)
Demographic and educational information: age, gender, semester, Grade Point Average (GPA), and source of bullying behavior (Classmate-professor-clinical instructor-nurses).
b)
Bullying Behaviors in Nursing Education Environments: A valid and reliable scale that developed by Cerit, Keskin [
49]; four factors consist of “Isolation of students from the education environment” (4 items), Attack on academic achievement (4 items), Attack on personality (6 items), Direct negative behaviors (4 items); A six-point Likert scale will use to define the frequency of behaviors (0: never experienced, 1: experience for a few times a year, 2: experience for a few times a month, 3:experience for a few times a week, 4: experience once a day, and 5: experience a few times a day). The higher score means the experience more bullying behaviors.
c)
The Belongingness Scale (Persian version): A valid and reliable scale that developed by Ashktorab, Hasanvand [
32]; 3 subscales consist of “self-esteem” (13 items), “connectedness” (10 items), and “efficacy” (8 items);a 5-point Likert scale ranging from 1 (never true) to 5 (always true). Higher mean scores are indicative of higher levels of belongingness.
d)
Intention to drop out: A valid and reliable scale that developed by Ekornes [
50]; eight items; a 5-point Likert scale (1 = strongly disagree; 5 = strongly agree). Higher mean scores are indicative of higher intention to drop out.
e)
Academic Major Satisfaction Scale (AMSS): A valid and reliable scale that developed by Nauta [
51]; six items, a 5-point Likert scale (1 = strongly disagree; 5 = strongly agree). The higher score means higher academic major satisfaction.
Translation and content validity
Except for the Belongingness Scale, which was already available in Persian, all other scales were translated into Persian following the World Health Organization’s 2016 protocol for forward–backward translation techniques. Subsequently, the Content Validity Ratio (CVR) and Content Validity Index (CVI) were employed to assess the necessity and relevance of the items. These evaluations were conducted by a panel of 10 experts specializing in psychometric studies and medical education. According to Lawshe’s 1975 table, the minimum acceptable CVR value when utilizing 10 experts was 0.62. Additionally, the minimum acceptable CVI value for each individual item was set at 0.7.
Data analysis
In a first step, to establish evidence of validity related to the internal structure of the constructs, Confirmatory Factor Analysis (CFA) was performed on the polychoric correlation matrix. The analyses utilized either the DWLS estimator for CFA or robust ML for the mediation model, both available in the lavaan package [
52] for the R statistical system (The R Foundation for Statistical Computing, 2021). The study employed a range of goodness-of-fit indices to assess the model’s fit, including the Chi-square statistic (χ2), Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), Root Mean Square Error of Approximation (RMSEA), and Standardized Root Mean Square Residual (SRMR). According to established criteria [
53,
54], an acceptable model fit is indicated by CFI and TLI values exceeding 0.90, and RMSEA and SRMR values falling below 0.06 and 0.08, respectively.
At the second step, reliability assessment, internal consistency analyses were conducted using the “SemTools” R package [
55]. Specifically, Cronbach’s alpha ordinal coefficient (α_ord) (Cronbach, 1951) and coefficient omega (ω) (McDonald, 2013) were calculated for each factor. The reliability of second-order constructs was assessed using ω_L1 (McDonald, 2013). A satisfactory level of internal consistency was indicated by alpha and omega values of 0.7 or higher, as recommended by Marôco (2021).
In the third and last step, the hypothetical mediation model was fitted and evaluated using the lavaan package, with standard goodness-of-fit indices applied for model assessment. Standard errors of model’s estimates were calculated by the lavaan’s delta method. Statistical significance tests relied on t-tests for the coefficients upon proper estimation of standard errors Additionally, R2 values were calculated for both mediator and criterion variables.
Ethical consideration
Upon receiving approval for the study protocol from the ethics committee of Alborz University of Medical Sciences [Ethic code: IR.ABZUMS.REC.1401.290], the questionnaire link was shared with students. The first page of the online questionnaire included essential information such as the study’s objectives, the number of items in the survey, the estimated time required for completion, the researcher’s affiliation and contact email for inquiries, and the study’s ethical code. Participants were informed that their participation was voluntary and that their responses would be aggregated and published anonymously. The online questionnaire items were not visible to participants until they agreed to participate by clicking the “Next” button, effectively completing the online informed consent form. Informed consent was obtained from all participants.
Discussion
This study found that bullying behaviors have a direct effect on the intention to drop out among Iranian nursing students. However, the negative effects of bullying on sense of belonging and major satisfaction were stronger, and these factors indirectly affected the intention to drop out. The study highlights the importance of addressing bullying behaviors in clinical settings to improve nursing students’ sense of belonging and major satisfaction, which can ultimately reduce their intention to drop out. The following discussion points can be made based on the study results and related search results. Bullying is a significant problem in the nursing profession, and nursing students are particularly vulnerable to bullying behaviors in clinical settings [
9,
14]. This can lead to decreased job satisfaction, absenteeism, tardiness, lack of teamwork, increased errors, poor communication, and collaboration [
9].
The study found that bullying behaviors have a direct effect on the intention to drop out among nursing students. This highlights the need for interventions to address bullying behaviors in clinical settings to prevent nursing students from dropping out of their programs. The study also found that sense of belonging and major satisfaction mediate the relationship between bullying behaviors and intention to drop out. This suggests that interventions aimed at improving nursing students’ sense of belonging and major satisfaction may help reduce the negative effects of bullying on their intention to drop out. Related search results suggest that school connectedness and resilience may also play a role in mitigating the negative effects of bullying on mental health and life satisfaction [
56,
57]. This highlights the importance of addressing bullying behaviors not only in clinical settings but also in educational settings more broadly.
Finally, related search results suggest that negative affect, core self-evaluations, and role conflict may also contribute to bullying behaviors among nurses [
58]. This highlights the need for interventions aimed at addressing these underlying factors to prevent bullying behaviors in the nursing profession.
This study sought to explore the relationships between Iranian nursing students’ experiences of bullying and their intentions to leave their educational programs, with particular attention to the mediating roles of major satisfaction and sense of belonging. Notably, university professors emerged as the most frequent perpetrators of bullying. Previous research conducted in Iran corroborated these findings, indicating that over half of nursing students had encountered bullying, predominantly from nursing instructors [
25,
59].
Several studies have reported that negative behavior from professors or instructors adversely impacted students’ levels of satisfaction and often led to the devaluation of nursing students. It’s worth noting that some educators may not intentionally engage in bullying behaviors, or may be unaware that their actions are perceived as such. Nevertheless, these behaviors contribute to feelings of humiliation, worthlessness, shame, and diminished self-confidence among nursing students. Moreover, punitive methods were more commonly employed than rewards in teaching practices [
60,
61]. Kang found that nursing students in Australia predominantly experienced covert forms of bullying, such as exclusion and being ignored [
62].
The findings of this study confirmed that experiences of bullying had a positive correlation with students’ intentions to drop out, thereby supporting Hypothesis 1 (H1). This aligns with existing literature, which indicates that bullying is a pervasive issue in academic settings and has detrimental effects on students’ attitudes toward their educational institutions, including reduced satisfaction and commitment. Exposure to bullying, whether as an observer or a victim, often leads to academic dissatisfaction and increases the likelihood of students discontinuing their programs prematurely [
60]. Our results are consistent with those of Martin, Goodboy [
22], who found that students subjected to bullying were more likely to consider leaving or actually exit their academic programs. Similarly, Abdollahi et al. reported that nursing students who experienced bullying in either university or clinical settings were deprived of meaningful learning opportunities, which in turn led to academic failure or withdrawal from their programs [
25].
The results of the current study corroborated the negative correlation between experiences of bullying and a sense of belonging among nursing students, thereby affirming Hypothesis 2 (H2). While most existing research on the relationship between bullying and a sense of belonging has been conducted in school settings, the findings are nonetheless relevant. For instance, Li et al. demonstrated that a sense of belonging in schools served as a mediator between bullying victimization and academic achievement, effectively buffering students against the negative consequences associated with bullying [
31]. Similarly, Huang found that students’ sense of belonging mediated the impact of both bullying victimization and the overall bullying climate on academic performance [
63]. Studies specific to nursing students also underscore the importance of a sense of belonging in determining the quality of educational experiences [
27,
32]. Patel et al. noted that bullying and incivility significantly erode nursing students’ commitment and feelings of belonging [
64]. Furthermore, negative educational environments characterized by power imbalances, peer rejection, and social exclusion can undermine students’ sense of belonging [
63].
The results of this study substantiated the negative correlation between experiences of bullying and major satisfaction among nursing students, thus confirming Hypothesis 3 (H3). Our findings indicate that exposure to bullying behaviors from professors, instructors, or peers significantly diminishes students’ interest and satisfaction in the nursing field. Professors and instructors serve as pivotal role models for students and are instrumental in shaping their interest in their chosen field of study. When these role models engage in bullying behaviors, it can lead to a disaffection for the nursing profession among students. This observation is supported by multiple studies, which have consistently found that bullying behaviors within educational settings adversely affect students’ perceptions of program satisfaction [
36,
65,
66]. Beyond its direct impact on field-specific satisfaction, bullying also disrupts the educational process. It undermines students’ self-confidence, induces emotional distress, and contributes to overall dissatisfaction with their educational experience [
36].
This study validated the mediating roles of major satisfaction and a sense of belonging in the relationship between students’ experiences of bullying and their intentions to drop out, thereby affirming Hypothesis 4 (H4). The findings elucidated the underlying mechanisms, suggesting that major satisfaction and a sense of belonging serve as key explanatory factors for why bullying in academic settings influences nursing students’ intentions to leave their programs. Marchiondo et al. posited that prolonged exposure to a bullying-prone academic environment is likely to diminish student satisfaction and elevate dropout rates [
66]. Similarly, Li et al. emphasized the strong correlation between a sense of belonging and academic performance, noting that students who feel a stronger sense of belonging tend to perform better academically [
31]. When students encounter a lack of respect, love, and acceptance from classmates or instructors, they are more susceptible to academic failure and are more likely to discontinue their studies. Instances of verbal or behavioral abuse, or feelings of isolation within the academic setting, can make it emotionally challenging for students to engage in their academic lives. Huang et al. underscored the critical importance of the concept of belonging in academic settings, stating that reduced feelings of belonging lead to decreased classroom engagement and, ultimately, to academic failure [
63].
The implications of bullying for nursing students are manifold, extending beyond the academic setting to include clinical environments. Research has consistently highlighted the prevalence of bullying and other forms of incivility in these settings. The treatment that nursing students receive in educational and clinical environments significantly influences their attitudes toward the nursing profession and their development as nurses. If students are socialized into a nursing culture that normalizes bullying, the long-term ramifications are concerning. Such students are likely to become disengaged, anxious, or depressed professionals in the future. Moreover, these individuals may perpetuate bullying behaviors, contributing to a cycle of incivility in the workforce. This not only heightens the risk of creating unhealthy work environments but also compromises the quality of nursing care. Ultimately, these factors have a detrimental impact on patient care outcomes, as corroborated by existing research [
67].
Limitations
The limitations for the present study were: (1) The study was conducted among Iranian nursing students, which may limit the generalizability of the findings to other nursing schools or regions. (2) The study relied on self-reported data, which may be subject to social desirability bias or recall bias. (3) The study did not explore other potential factors that may affect the intention to drop out, such as academic performance, financial burden, or family responsibilities. (4) The study did not investigate the long-term effects of bullying on nursing students’ mental health, career satisfaction, or patient care outcomes. (5) The cross-sectional research design employed in this study limits the ability to draw valid causal inferences. Theoretical causal hypotheses are theory driven and basic assumption for structural equation models. Significance of estimates of the model derived from correlations between variables, support the validity of the hypothesis, but do not prove it beyond statistical confirmation.
Implications for nurse education
The present study in nursing education found that bullying has a direct effect on the intention to drop out, but the effect is weaker than the indirect effects mediated through belongingness and major satisfaction. Belongingness and major satisfaction were also found to be statistically significant related to intention to drop out. Additionally, bullying had a negative effect on belongingness and major satisfaction. These findings suggest that addressing bullying in nursing schools and throughout a nurses’ career is crucial to prevent nurse attrition and improve clinical and financial outcomes for healthcare organizations. Strategies for addressing bullying in nursing schools and organizations may include encouraging nurses to hold each other accountable, implementing measures to prevent bullying, and empowering nurses to call out bullying behaviors.
The negative impact of bullying behavior in academic settings extends to students, educational institutions, and the broader nursing profession. Our findings underscore that nursing students subjected to bullying within university environments are at a heightened risk of discontinuing their studies. These results emphasize the critical need for anti-bullying interventions within academic settings, particularly targeting faculty behavior. Efforts to mitigate academic failure and reduce dropout rates could benefit from strategies aimed at fostering a stronger sense of belonging within the university community and enhancing major-specific satisfaction among nursing students.
