Abstract

Objectives

Specialty nurses play a significant role in improving patient care; however, little is known about the factors affecting their work engagement. This study aimed to explore the relationship between role stress and work engagement among specialty nurses in China.

Design

A descriptive, cross-sectional study was applied in this study.

Setting

The study was conducted in the Henan Provincial People’s Hospital in China.

Participants

From March to April 2023, we conducted a cross-sectional descriptive study, using convenience sampling to recruit 972 specialty nurses from 42 specialised fields in China.

Methods

An online questionnaire survey was conducted using the Basic Information Questionnaire, Role Stress Scale and Specialty Nurse Work Engagement Scale. The collected data were analysed by using SPSS 21.0 software. The differences in total work engagement scores between subgroups were investigated using a single-factor analysis of variance. A Spearman’s rank correlation and a Pearson’s correlation were used to determine the relationship between general information, role stress and work engagement. A ridge regression analysis explored the impact of role stress on work engagement.

Results

The total score of role stress was (52.44±19.92) and the total score of work engagement was (140.27±17.76). Among the scores of various dimensions of specialty nurses’ work engagement, the standardised score for work attitude was the highest (4.54±0.56), followed by work values (4.46±0.64); the standardised score of work enthusiasm and focus was the lowest (4.22±0.64). Additionally, role ambiguity (r=−0.352, p<0.001), role conflict (r=−0.367, p<0.001), role overload (r=−0.313, p<0.001) and role stress (r=−0.380, p<0.001) were negatively correlated with work engagement. The total score of role stress was negatively correlated with the total score of work engagement; the results of ridge regression analysis showed that age, professional title and role stress explain 14.6% of the variance in work engagement.

Conclusion

Our study found that specialty nurses’ work engagement was mid-level or above. Role stress was significantly and negatively correlated with specialty nurses’ work engagement, which was an important predictor of their work engagement. Nursing managers should instate effective measures to reduce role stress, thereby increasing work engagement.

pmcSTRENGTHS AND LIMITATIONS OF THIS STUDY

This study focused on the work engagement of specialty nurses rather than general nurses.

Using large sample of specialty nurses, this study investigates the association of specialty nurses’ role stress and work engagement in China.

This study can provide new perspectives for nursing managers to develop strategies to improve specialty nurses’ work engagement.

This was a cross-sectional study, which makes it unfeasible for us to specify the effect of time.

Using a convenience sample may lead to an increased likelihood of sampling bias.

Introduction

The term ‘specialty nurses’ refers to registered nurses who have obtained the corresponding specialty nurse qualification certificate after systematic training and examination.1 Compared with general nurses in China, specialty nurses have profound theoretical nursing knowledge, expert nursing skills and rich clinical experience in a specific nursing field.1 They mainly play a role in specialised practice, scientific research, teaching, management, outpatient clinics, consultations and discussion of difficult cases.2 Studies have shown that specialty nurses play a significant role in improving patient care and treatment compliance, meeting all aspects of patient needs and improving patient health.3 4 Accordingly, how to improve the performance of specialty nurses and facilitate the full use of their roles has captured wide attention worldwide.

Work engagement has emerged as a crucial topic for the performance of specialty nurses while also serving as the basis for the competitiveness of hospitals.5 Schaufeli et al define work engagement as a positive, job-fulfilling state of mind characterised by energy, dedication and focus.5 Related research showed that the work engagement of nurses in countries such as the USA, Spain and Belgium was at a moderate to high level.68 Conversely, the level of work engagement among Chinese nurses is relatively low.9 10 Low work engagement may result in a significant decline in nurses’ subjective well-being, professional identity and work efficiency, which can severely affect the overall quality of medical services and jeopardise patient safety and health outcomes.11 Specialty nurses may face more severe pressure challenges due to their high degree of professionalism, significant responsibilities and multiple roles.12 Therefore, it is necessary to understand the current status of specialty nurses’ work engagement and clarify the influencing factors, thereby providing valuable evidence for intervention strategies.

Existing literature on work engagement among specialty nurses primarily focuses on dental, haematology, operating room nurses and the like.1315 These studies were limited to specialty nurses in a particular field and were not adequately representative of the specialty nursing population. Studies have shown that five pivotal categories of factors-individual-related, organisational-related, job and role-specific, work–life harmony and workplace environment-collectively impact the nurses’ level of work engagement. Additionally, stress has been identified as a significant work environment factor that contributes substantially to work engagement.1618 Role stress has been conceptualised as the result of a discrepancy between an individual’s perception of specific role characteristics and the actual implementation of such a role. Role stress occurs when a divergence exists between what is perceived to be the role expectations and what is being accomplished within the role.19 Nurses experience various sources of work-related stress, including shift work, heavy workloads, long hours and conflicting job demands.20 Specialty nurses, in particular, are required to simultaneously perform six clinical roles, as practitioners, coordinators, ethicomoral coordinators, consultants, educators and researchers.21 Thus, they undertake more challenging clinical tasks than general nurses do. Additionally, specialty nurses mainly engage in part-time work in China, which means that they are responsible for both routine clinical nursing responsibilities and professional nursing tasks, further intensifying their role stress.22 Although role stress is a common problem faced by specialty nurses, there is still a lack of relevant data to confirm its relationship with work engagement.

The job demands-resources (JD-R) model serves as a widely accepted theoretical framework for delineating the precursors and consequences of work engagement. It delineates two primary facets: job demands and job resources, each with distinct implications. Job demands encompass the physiological, psychological or organisational requisites that employees must satisfy, involving significant physical and mental exertion. Conversely, job resources catalyse an incentive process, fostering positive results related to performance.23 However, job demands can transition into job stressors when they require an individual to exert an elevated level of effort to meet these requirements,24 potentially yielding adverse effects such as nervousness and depression, which, in turn, influence employee engagement.25 Among specialty nurses, factors like role overload, role ambiguity and role conflict may lead to role stress, consequently diminishing their work engagement levels.26 Therefore, drawing from the JD-R model, we hypothesise a negative correlation between role stress and work engagement among specialty nurses, with role stress emerging as a pivotal predictor of work engagement in this demographic.

The purpose of this study was to fill a research gap in the relevant field by investigating the relationship between personal characteristics (such as hospital type, hospital grade, specialised fields, gender, age, educational level, professional title, work experience, mode of appointment, monthly income), participation in specialised nursing work (whether to participate in specialty nursing outpatient service, nature of specialty nurse position) and role stress in relation to work engagement among specialty nurses. The results of this study may provide a new perspective for nursing managers to improve work engagement among specialty nurses and to stabilise the specialty nursing team.

Research methods

Research approach

The study employed a descriptive, cross-sectional design to investigate the correlation between role stress and work engagement among specialty nurses in China. Several key factors informed the adoption of this survey approach. First, it offers simplicity in data collection and analysis.27 28 Second, the method facilitates the acquisition of precise data from a substantial pool of respondents within a constrained time frame. Additionally, empirical evidence supports the suitability of cross-sectional studies for both descriptive and comparative analyses, aligning closely with the objectives of our investigation.29

Participants

Convenience sampling was used to select specialty nurses from 42 different specialised fields, from March to April 2023, as the study participants. The inclusion criteria were as follows: (a) being a registered nurse, (b) having a specialty nursing training certificate, (c) having over one year of specialty nursing work experience and (d) volunteering to participate in the study. Additionally, we excluded those who did not belong to the hospitals being surveyed and those who took sick or maternity leave or were absent for more than 6 months.

Patient and public involvement

Patients or the public were not involved in this study.

Measurements

We used established measures for the constructs in this study, which have been extensively employed within the Chinese nurse population and have demonstrated robust reliability and validity. To enhance the study’s rigour, we recalculated the reliability. In this study, Cronbach’s α coefficient for the Role Stress Scale was 0.956, and for the Specialty Nurse Work Engagement Scale, it was 0.978.

General Information Survey Questionnaire

The following general information was collected from each participant: hospital type, hospital grade, department, sex, age, educational level, professional title, work experience, mode of appointment, monthly income, whether to participate in the specialty nursing outpatient service and nature of the specialty nurse position.

Role Stress Scale

The scale used in this study was a 23-item scale revised by Li, based on the original Role Stress Scale and Role Load Scale, to measure three dimensions: role ambiguity (6 items), role conflict (7 items) and role overload (10 items).3032 Each item was scored on a 5-point Likert scale ranging from 1 (very inconsistent) to 5 (very fit), with a total score calculated as the sum of individual item scores, ranging from 0 to 115. The Content Validity Index for the overall scale (S-CVI) is 0.930. The Cronbach’s α coefficient for the scale was 0.961.

Specialty Nurse Work Engagement Scale

The Chinese version of the Specialty Nurse Work Engagement Scale developed by Qin et al was used in this study.33 This 32-item scale has five subscales: work attitude, work value, work recognition, work initiative, work enthusiasm and focus. Each item was scored on a 5-point Likert scale ranging from 1 (never) to 5 (always), with a total score out of 160 calculated as the sum of individual item scores. The S-CVI is 0.842 and Cronbach’s α coefficient for each domain ranged from 0.827 to 0.905, and for the total scale it was 0.958.

Data collection

An online survey was conducted in Henan Province, which is a populous province located in central China. The electronic questionnaire was developed on a widely used online platform, Wenjuanxing, which generated a website link to the electronic questionnaire. Before the survey, the managers of 42 specialty nurses’ training bases were contacted to inform them of the study’s aims and procedures. After obtaining permission, we sent them a website link to access the questionnaire, which they distributed through a WeChat group to specialty nurses who met the inclusion criteria. The first page of the questionnaire included standardised instructions to explain the survey purpose and methodology, as well as informed consent, which helped ensure that the recovered questionnaires were comprehensive and valid. Participants completed the questionnaire online via electronic devices (eg, smartphones). During the data collection phase, all items in the questionnaire were compulsory, to avoid omission of answers, and each internet protocol address was allowed to fill out the survey only once, to prevent duplicate responses. After questionnaire collection, two researchers who were uninformed of the study design entered the data after all surveys were completed, to ensure accuracy. Before analysing the data, they received training on the subject and were only allowed to participate in data entry if they passed the training exam. Two researchers jointly checked the questionnaires during data entry and eliminated those with obvious errors or inconsistencies.

Data analysis

A Kolmogorov-Smirnov test was used and indicated that the total scores of work engagement did not satisfy a normal distribution (p<0.05). However, Kim argues that if the sample is >300, normality should depend on the absolute values of skewness (absolute skew value >2) and the absolute value of kurtosis (absolute kurtosis >7) and be assessed reliably in conjunction with the visual appearance of distributions.34 In our study, the total scores of work engagement had an absolute skew value of −0.820 (SE=0.079) and an absolute kurtosis value of 1.195 (SE=0.158). Considering the results of these skewness and kurtosis values, along with the distribution plots (Q-Q plots), the total scores of work engagement in this study approximated normality.

Next, we employed tolerance and a variance inflation factor for collinearity diagnostics. The results showed that there is an internal link between the professional title and work engagement—this is referred to as multicollinearity. To maintain the integrity of the explanatory variables, the ridge regression analysis method was used.

The continuous data were described as means and SD, and categorical data were presented as frequencies and percentages. The differences in the total score of work engagement between subgroups were tested, using independent samples t-test or one-way analysis of variance (ANOVA), if the data met homogeneity of variance. Spearman’s correlation analysis to analyse the correlation between demographic variables and work engagement. The relationships between role stress and work engagement were explored using Pearson correlation analysis. Specialty nurses’ scores of work engagement were treated as dependent variables in the ridge linear regression analysis, the role stress and statistically significant factors in the univariate analysis as the independent variables, and the k value was set to 0.3. In ridge linear regression analysis, age, professional title and work experience are set as dummy variables, and the reference groups were aged ≤30 years, primary nurses and work experience ≤5 years, respectively. Statistical significance was set at p<0.05 (two-tailed test).

Results

Characteristics of the sample

The study received 972 questionnaires, of which 14 were excluded because of obvious errors (eg, all answers were the same and the options selected were regular). Finally, 958 valid questionnaires were included (98.5%). Among the included questionnaires, there were 909 females (94.9%) and 49 males (5.1%). The average age of the participants was (33.6±4.84) years. Detailed demographic characteristics are presented in table 1.

Univariate analysis of the different general information on work engagement of specialty nurses

Significant differences were found in the total work engagement score among specialty nurses when comparing different age groups, professional titles and years working in the hospital (p<0.05) (table 1). There was no statistically significant difference in role stress between specialty nurses who participate in specialty nursing outpatient service and those who do not participate in specialty nursing outpatient service. Meanwhile, the difference in role stress between full-time and part-time specialty nurses was also not statistically significant (p>0.05) (table 1).

Analysis of work engagement and role stress of specialty nurses

The total score of work engagement was 140.27±17.76 and the total score of role stress was 52.44±19.92. Detailed scores for each dimension of work engagement and role stress are shown in tables2 3.

The correlation between specialty nurses’ general information, role stress and work engagement

As shown in table 4, the results of the Pearson correlation analysis indicated that the total score for work engagement was negatively related to the total scores for role stress (r=−0.380, p<0.001), role ambiguity (r=−0.352, p<0.001), role conflict (r=−0.367, p<0.001) and role overload (r=−0.313, p<0.001). The result of the Spearman’s correlation analysis revealed that age (r=0.061, p<0.05), professional title (r=0.088, p<0.05) and work experience (r=0.135, p<0.001) were positively associated with work engagement.

Analysis of factors influencing specialty nurses’ work engagement

According to the results of the independent samples t-test or one-way ANOVA, age, professional title and work experience were statistically significant general information variables, which were included in the ridge regression analysis. The results showed that when age, professional title, and role stress were entered into the regression model, they explained 14.6% of the variation in work engagement. Role stress had a significant negative effect on work engagement (β=−0.335, p<0.001). However, compared with specialty nurses aged ≤30 years, specialty nurses aged 31–40 years, 41–50 years or >51 years did not show significant differences in work engagement. Compared with specialty nurses with a professional title of primary nurse, specialty nurses with a professional title of nurse practitioner, supervisor nurse and co-chief nurse did not show significant differences in work engagement. Furthermore, compared with specialty nurses with work experience ≤5 years, specialty nurses who worked in a hospital for 6–10 years, 11–15 years, 16–20 years, 21–25 years, 26–30 years or >31 years did not report significant differences in work engagement (table 5).

Discussion

The total score for work engagement was (140.27±17.76), with a mean item score of work engagement (4.38±0.56). This score surpasses the normative data for total work engagement scores of nurses (3.82±1.10) and is consistent with the findings reported by Qin et al and other studies.33 35 36 Our study indicates that the level of work engagement among specialty nurses is above medium level. This may be because specialty nurses play a crucial role in clinical practice and receive greater recognition from nursing managers than general nurses do. Nursing managers were more willing to provide specialty nurses with additional resources and opportunities to enhance their work engagement. Further analysis was made on the scores of all dimensions of specialty nurses’ work engagement, among which the standardised score of work attitude was the highest (4.54±0.56), followed by work values (4.46±0.64). This may be related to the increased recognition of specialty nursing work by patients, medical staff and society, which has greatly improved the existence and value of specialty nurses. However, the standardised score of work enthusiasm and focus was the lowest (4.22±0.64) among dimensions of work engagement. This may be related to factors such as ambiguous job responsibilities, significant disparities in salary and benefits, and excessive workload, which, in turn, can lead to negative emotions and professional stress among specialty nurses.3739 These factors can diminish their sense of professional gains, thus exerting a negative impact on their work enthusiasm, motivation and focus.

The single-factor ANOVA showed that the differences in specialty nurses’ work engagement in terms of age, professional title and work experience were statistically significant (p<0.05). These findings are consistent with those of previous studies regarding general nurses.4042 The reasons may be as follows. Specialty nurses are of different ages, and therefore, assume different family roles, leading to differences in their work–family conflict levels; this results in different levels of work engagement.13 Different levels of professional title or qualification affect specialty nurses’ earnings and their feelings of professional accomplishment.43 Therefore, they enjoy different benefits, demonstrate a different sense of work value and their level of work engagement varies. Further, specialty nurses with different levels of work experience may have differences in their professional knowledge and skill levels, resulting in differences in their ability to handle complex situations, meaning that their level of work engagement varies.44 However, age, professional title and work experience could not be entered into the regression equation, which could be because of the internal link between these factors influencing work engagement, leading to multicollinearity. Therefore, whether age, professional title and work experience are influencing factors of specialty nurses’ work engagement needs further research. Our study also observed variations in the number of specialty nurses across different specialised fields; however, these variances did not demonstrate significant differences in work engagement (p>0.05), consistent with previous research results.45 This could be attributed to the variations in demand for specialty nurses across different fields, as medical institutions allocate human resources based on specific requirements. For example, the intensive care unit often requires a larger team of specialty nurses owing to the specialised and demanding nature of the work, ensuring timely and proficient patient care.46 Nevertheless, further investigation is warranted to explore the phenomenon of non-significant differences in work engagement among specialty nurses across diverse specialised fields.

One interesting finding was that there was no statistically significant difference in role stress between specialty nurses who participate in specialty nursing outpatient service and those who do not. Moreover, the difference in role stress between full-time and part-time specialty nurses was also not statistically significant, which is inconsistent with the findings of previous reports.33 The reason may be related to the low proportion of full-time specialty nurses and specialty nurses participating in outpatient services in our study. It may also be related to the fact that our survey respondents came from different provinces in China, which have different post management systems, promotion systems and salary systems for specialty nurses. Therefore, the relevant government departments should comprehensively consider the opinions of various medical institutions, issue relevant policy guidance, realise homogeneous management of specialty nurses and improve the level of work engagement of specialty nurses.47

Our study further discovered that role ambiguity, role conflict, role overload and role stress were all negatively correlated with the work engagement of specialty nurses; this is consistent with previous studies regarding general nurses.48 49 In terms of role ambiguity, this issue arises when medical staff assumes multiple roles, such as treating patients, undertaking research, teaching junior colleagues and so forth.41 Unclear role positioning and job responsibilities lead to specialty nurses being unable to focus on their work.48 Regarding role conflict, specialty nurses have regular clinical nursing duties while also having to perform specialised nursing tasks.50 Moreover, most specialty nurses are women who have the additional responsibility of taking care of their families, which might lead to a reduction in the time and energy they invest in specialty nursing work.51 Finally, in the dimension of role overload, as most specialty nurses work part-time in China—meaning that specialty nurses are required to undertake more tasks such as scientific research, teaching and management—and deal with more complex work than general nurses, they are more susceptible to negative emotions and feelings of exhaustion, which reduces their work engagement.50 51 To address this, medical institutions should actively explore work management systems, salary systems and promotion systems for specialty nurses that are in line with their clinical environment, to thereby reduce the impact of role ambiguity, role conflicts and role overload on the work engagement of specialty nurses.51

The ridge regression analysis demonstrated that role stress was the primary factor influencing the work engagement of specialty nurses. Our results are consistent with those of previous studies on dental nurses.13 It may be related to that when specialty nurses are subjected to long-term pressure from their work, patients and environment, these role stressors can lead to fatigue and a decrease in enthusiasm and motivation, resulting in lower levels of work engagement and even turnover.42 Therefore, we suggest that nursing managers pay attention to role stress experienced by specialty nurses. To enhance communication and create a supportive environment for specialty nurses, establishing effective channels through which they can express their thoughts and feelings is crucial. This not only helps alleviate stress but also promotes a sense of psychological well-being. Furthermore, offering mindfulness training to specialty nurses could effectively reduce psychological pressure and boost work engagement.

Limitations

Despite its clear contributions, this study has certain limitations. First, this was a cross-sectional study, which makes it unfeasible for us to specify the effect of time. Second, this study collected data using an online questionnaire, which could potentially be subject to interpretation biases and deviations, due to individual misinterpretation. Third, the survey participants were not selected using probability-sampling strategies, which also limits the generalisability of our research findings. Lastly, the 5% male specialty nurses in our sample only represent the male specialty nurse population within mainland China; therefore, the applicability of our findings as a reference for developed countries is limited.

Conclusions

This work contributes empirically to the existing literature concerning specialty nurses’ engagement and the JD-R model by exploring the role stress-related aspects which assist in reducing the negative impacts on the engagement of specialty nurses. We conducted a large-sample survey to test the hypothesised relation between specialty nurses’ role stress and work engagement. Findings from this study suggest that specialty nurses’ work engagement was in the middle to upper range and higher than general nurses. Furthermore, role ambiguity, role conflict, role overload and role stress were negatively correlated with the work engagement of specialty nurses. Notably, role stress was the main factor influencing their work engagement. Given that the concept of work engagement has emerged as a significant driver for fostering positive attitudes and behaviours among specialty nurses, this study suggests that nursing managers should take specific measures to address the role stress of specialty nurses to reduce their stress and increase their work engagement.

Implications for nursing management

The results of this study indicate that the relevant government departments should comprehensively adopt the opinions of various medical institutions and issue relevant policy guidance. Moreover, each medical institution should actively explore work management systems. Nursing managers should also pay attention to the negative impact of role stress on work engagement and implement effective measures, such as creating a supportive environment for specialty nurses; establishing effective channels to express their thoughts and feelings is crucial and offering mindfulness training to specialty nurses, to thereby reduce their role stress and improve the level of specialty nurses’ work engagement.
