Background: Little is known about the associated factors with organizational citizenship behavior among Chinese nurses combating COVID-19. The aim of the present study was to investigate the relationships between autonomy, optimism, role conflict, work engagement, and organizational citizenship behavior based on moderated mediation models among Chinese nurses combating COVID-19.
Methods: This cross-sectional study was performed on a sample of 368 nurses supporting the COVID-19 epidemic in Wuhan Leishenshan Hospital, China. According to the Job Demands-Resources model, two moderated mediation models were tested, in which autonomy/optimism was associated with organizational citizenship behavior through work engagement, when role conflict served as a moderator.
Results: This current study found the mediating effect of work engagement and the moderating effect of role conflict on the relationship between autonomy/optimism and organizational citizenship behavior among nurses. Of note, nurses working in the COVID-19 epidemic viewed role conflict as challenge job demands rather than hindrance job demands.
Conclusion: Based on the findings, organizational citizenship behavior can be affected by work engagement and role conflict. Nursing management is suggested to put emphasis on work engagement and role conflict among nurses supporting the COVID-19 epidemic.

Keywords: the job demands-resources model, autonomy, optimism, organizational citizenship behavior, nurses, COVID-19

Introduction

The healthcare system has been overwhelmed after the COVID-19 outbreak. Being the largest health profession, as well as the only professional at a patient’s bedside in a 24-hour period, the nurse workforce plays a crucial role in the delivery of quality healthcare services for patients with COVID-19. Nurses combating COVID-19 may face enormous challenges including high-level working standards and a tough work environment. These challenges may have a huge impact on nurses’ organizational citizenship behavior1 which refers to a type of positive work behavior that is not explicitly part of the job description and is also not officially required by the occupation.2 A high level of organizational citizenship behaviors among nurses increases team cooperation, strengthens organizational productivity, and helps the organization respond to challenge.3 It is necessary to focus on organizational citizenship behavior among nurses deliver healthcare for patients with COVID-19.

In addition to organizational citizenship behavior, work engagement is also critical for nurses as it is related to the quality of healthcare services for patients.4 Employees with high levels of work engagement can be energetic, because they feel a fulfilling state of vigor and become so immersed in their work activities.5 An experimental study found that individuals with a high level of engagement are more likely to complete tasks excellently because they pay attention to the task and dedicate themselves to their work.6 Work engagement has become an important issue, so considerable attention has been paid to the antecedents of work engagement.7

Existing research has identified the antecedents of work engagement based on the Job Demands–Resources (JD–R) model.7 Drawing on the JD–R model, job resources facilitate a motivational process where resources can predict work engagement. Examples of job resources are autonomy and social support.1 Autonomy can help individuals to have flexibility and freedom when they work, improving the level and depth of their job-related knowledge.8

The JD-R theory cannot only focus on employee well-being (e.g., work engagement), but also predict organizational citizenship behavior.9 Job resources can have a positive impact on job performance through work engagement based on the motivational process.1 Keyko et al found that job autonomy positively related to work engagement, leading to positive outcomes among nurses.10 However, little is known about whether work engagement may serve as a link between autonomy and organizational citizenship behavior.

Hypothesis 1. The association between autonomy and organizational citizenship behavior will be positively mediated by work engagement.

Like job resources, personal resources serve as an antecedent of work engagement. This means that personal resources indirectly affect job performance through work engagement.1 Optimism can be seen as one kind of personal resources including the willingness of an individual to experience good achievements and avoid bad events.11 When individuals are faced with challenges at work, optimism can help them look at the positive sides of the situation and overcome difficulties.12 The existing literature about the effect of optimism as personal resources has been investigated through the JD-R model. Chen (2018) reported that optimism can affect job performance via work engagement. However, few empirical investigations looking at the relationship between optimism, work engagement, and organizational citizenship behavior.

Hypothesis 2. work engagement will positively mediate the relationship between optimism and organizational citizenship behavior.

According to the JD-R theory, job demands include hindrance and challenge demands. Challenge job demands include a high workload and long working hours, while hindrance job demands include role ambiguity and role conflict.13 Role conflict refers to “the behavior of a person who is within a role need to meet the incompatible expectations”.14 When nurses work in some special hospitals, they may face many challenging situations, like long hours of work and insufficient time to relax.

Drawing on the JD-R model, job resources and personal resources both have an impact on work engagement when job demands act as a moderator.1 For example, Bakker et al have found that job resources have a strong relationship with work engagement when job demands are at a high level.15 Chen et al found that the relationship between personal resources and work engagement can be moderated by job demands.7 Role conflict served as a moderator in the association between empowering leadership and exploration.16 However, the moderating effect of role conflict on the relationship between autonomy/optimism and work engagement has not been studied yet.

Hypothesis 3. The effect of autonomy on engagement will be moderated by role conflict.

Hypothesis 4. The effect of optimism on engagement will be moderated by role conflict.

It is suggested that both autonomy and optimism can affect organizational citizenship behavior through work engagement (H1, H2). Additionally, it is proposed that the relationship between autonomy/optimism and engagement can be moderated by role conflict (H3, H4). Consequently, it is necessary to test moderated mediation models. This means that the effect of autonomy and optimism on organizational citizenship behavior via engagement is moderated by role conflict (Figure 1).

Hypothesis 5. The indirect effect of autonomy on organizational citizenship behavior through work engagement will be moderated by role conflict.

Hypothesis 6. The indirect effect of optimism on organizational citizenship behavior through work engagement will be moderated by role conflict.

Method

Study Units and Participants

This study was conducted among nurses in March 2020. Convenience sampling was used to recruit nurses from Wuhan Leishenshan Hospital. All data were collected through electronic questionnaires that were anonymous and distributed through Wechat. The first page of the electronic questionnaire provided detailed information for participants who can provide informed consent using click-box agreements via electronic questionnaires. Those who did not agree were directed to close the online survey. This study was conducted in accordance with the Declaration of Helsinki. A total of 479 nurses were invited and 368 nurses agreed to participate and completed the electronic questionnaires.

Measures

Autonomy

Autonomy was measured with the job autonomy survey scale from the Job Diagnostic Survey developed by Hackman et al.17 The Chinese version of this scale includes three items.18 One of these items is: “Can you decide for yourself how to execute your work?”17 This scale is a 7-point scale ranging from 1 =very little to 7=very much.

Optimism

A four-item scale of the Life Orientation test scale was used to measure optimism.19 We used the Chinese version of the scale in this study.20 One sample item in the short scale was, “I am always optimistic about my future”.19 The participants rated each item on a 5-point scale ranging from 0=strongly disagree to 4=strongly agree.

Work Engagement

The Utrecht Work Engagement Scale-9 was used to measure work engagement.21 There are three dimensions in this scale: vigor, dedication, and absorption. Each dimension contains three items. Bakker et al have recommended the use of three dimensions to evaluate work engagement among employees.22 The Chinese version of this scale has been widely used.23 One sample item was, “At my work, I feel that I am bursting with energy”.21 The participants responded to each item on a 7-point scale ranging from 0=never to 6=always.

Role Conflict

During the pandemic, nurses facing a lack of time and energy can experience a high level of role conflict as challenge job demands.24 Role conflict was assessed using the 3-item role conflict scale.25 The Chinese version of this scale has been widely used.26 One sample item was, “I often get involved in situations in which there are conflicting requirements”.25 This is a 5-point scale ranging from 1=completely not true to 5=completely true.

Organizational Citizenship Behavior

The 10-item scale developed by Bachrach et al was used to assess organizational citizenship behavior.27 There are two dimensions in this scale: helping (seven items) and civic virtue (three items). It is suggested that researchers can use two dimensions to evaluate organizational citizenship behavior among employees.27 One sample item was “Help other employees out if someone falls behind in his/her work”.27 This is a 5-point scale ranging from 1 =completely not true to 5=completely true and it has been widely used in China.28

Statistical Analysis

The descriptive information, Cronbach’s alpha, average variance extracted, and correlation matrix were calculated using SPSS Version 24. PROCESS macro based on ordinary least-squares regression was used in this study.29 Model 4, model 1 and model 7 of PROCESS macro were adapted to test the mediation, moderation, and moderated mediation hypotheses. The number of bootstrap samples was 5,000 in this study. Simple slope analysis was performed for probing interaction. An “index of moderated mediation” was generated by using a bootstrap confidence interval. Point estimates were significant when the bootstrap 95% confidence interval did not contain zero.

Results

Preliminary Analyses

Table 1 presents means, standard deviations, Cronbach’s alpha, average variance extracted (AVE), and correlations of study variables. AVE for organizational citizenship behavior, engagement, autonomy, optimism, and role conflict was 0.70, 0.57, 0.76, 0.64, and 0.68, respectively, exceeded 0.50; this indicated that convergent validity was satisfactory. In Table 1, the square of the root of AVE values exceeded the construct correlation values suggesting that discriminant validity is satisfactory.

Mediation Analyses

Model 4 of PROCESS macro was adapted to examine if work engagement was a mediator. The indirect effect of autonomy on organizational citizenship behavior via engagement was significant (b=0.10, SE=0.02, 95% CI=[0.07, 0.14]), and the indirect effect of optimism on organizational citizenship behavior was also significant (b=0.22, SE=0.04, 95% CI=[0.15, 0.31]) (Table 2).

Moderation Analyses

The association between autonomy and engagement was moderated by role conflict (b =0.10, SE=0.03, t=3.00, p=0.003), while the relationship between optimism and engagement was also moderated by role conflict (b =0.21, SE=0.08, t=2.55, p=0.01). Figure 2 reveals that autonomy was more strongly related to engagement at high levels of role conflict (b =0. 37, SE=0.05, t=7.75, p<0.001) than at low levels of role conflict (b =0.18, SE=0.05, t=3.63, p<0.001). Figure 3 reveals that optimism was more strongly related to engagement at a high level of role conflict (b =1.02, SE=0.12, t=8.45, p<0.001) than at a low level of role conflict (b=0.61, SE=0.10, t=5.89, p<0.001).

Moderated Mediation Analyses

The indirect effect of both autonomy and optimism on organizational citizenship behavior was strongest at the higher levels (+1 SD) of role conflict and weakest for those who were at the lowest (−1 SD) levels of role conflict. Moderated mediation analyses showed that the confidence intervals of moderated mediation index did not contain zero (Table 3).

Discussion

This study aimed to explain organizational citizenship behavior among Chinese nurses combating COVID-19 in Wuhan on the basis of the JD-R model. The findings support all hypotheses.

This study suggests that autonomy can affect organizational citizenship behavior via work engagement. This finding accords with earlier research. A study found that nurses with more autonomy become more engaged, so that they have less intention to leave.30 According to the JD-R model, autonomy can help improve nurses’ growth, learning and development due to its motivational effects. In such cases, nurses could become engaged, and this fulfilling, positive work-related state of mind can predict organizational citizenship behavior.31

This study also suggested that optimism affected organizational citizenship behavior through engagement. A previous study showed that for professional nursing practice, personal resources can influence job performance via work engagement.10 Optimistic nurses will believe that life has full of positive things, so unforeseen events and setbacks can always be handled. Nurses with such beliefs have the ability to focus on tasks and complete tasks effectively leading to work engagement. Engaged nurses are more likely to follow to all organizational ethics and standards resulting in practice better organizational citizenship behavior.

We found that the association between autonomy/optimism and work engagement can be moderated by role conflict in this study. A previous research found that job insecurity as a job demand can moderate the relationship between job resources/optimism and work engagement.7 Job resources and personal resources have a strong impact on work engagement when job demands are high. Various job demands in the work environment can have a different effect on work engagement.22 Challenge demands are beneficial to work engagement and performance, whereas hindrance demands are detrimental to work engagement and job performance.22 For instance, a study found role-conflict as hindrance demands can affect work engagement negatively.32 Bakker and Demerouti argued that individuals may perceive hindrance demands as challenge demands (and vice versa).22 One possible reason may be that the effects of various job demands depend on professionals and the context. For example, nurses consider work pressure as hindrance demands because insufficient time makes it impossible to offer patients care, fostering negative events, such as stress and disappointment.22

In this study, nurses see role conflict as challenge demands which boost the relationships between autonomy/optimism and engagement and enhance the indirect effect of autonomy/optimism on organizational citizenship behavior via engagement. One possible explanation is that those nurses have a sense of responsibility and collective action, with a high level of solidarity to work. Additionally, the nurses felt very supported by the administration and the community and were given enormous resources to manage the pandemic. Nurses were publicly applauded by the community and the media. Therefore, when nurses are confronted with a complicated situation and conflicting requirements, they perceived role conflict as challenge demands rather than difficulties.22 In such a case, autonomy/optimism can be viewed as a coping mechanism, which can constantly change cognitive and behavioral efforts to cope with these demands leading to work engagement and organizational citizenship behavior.9 However, if the context is changed, nurses may view role conflict as hindrance demands.

As work engagement has been placed in the central role in the JD-R model, interventions to promote work engagement should be adopted among nurses.33 Recovery training and job crafting training can be adopted by organizations to foster work engagement.34 For instance, job crafting training courses can raise nurses’ awareness about the measures that they can adapt based on personal needs and preferences. Consequently, it helps nurses adjust their jobs and become engaged by using their strengths. Optimizing job demands is also crucial to work engagement. As challenge job demands are regarded as obstacles by nurses to be overcome, these types of demands, such as role conflict and complex tasks, are positively related to work engagement. Organizations should make an effort to provide teaching teams to help nurses combine challenge demands with sufficient job resources to improve their work engagement and job performance.34 However, it is important to keep in mind that role conflict may be regarded as hindrance demands if the context changes.

Study Limitations

Some limitations should be considered in our study. First, it is impossible to conclude the directionality of causal relationships based on this cross-sectional study. Future longitudinal studies are encouraged in order to draw firm conclusions. Second, role conflict was only measured as a job demand. Future studies are encouraged to include different types of job demands in this population. Third, the results are only based on nurses who combat COVID-19 in Wuhan, which means that generalization of the findings can be limited. However, as the COVID-19 pandemic continues to spread across the world, this study may provide new insights into nurses’ occupational health and job performance in this global pandemic.

Conclusion

Consistent with the JD-R model, this study found that autonomy and optimism are protective factors to organizational citizenship behavior. The mediation analysis suggests that work engagement can be seen as a mediator between autonomy/optimism and organizational citizen behavior. Moreover, autonomy and optimism help to sustain nurses’ work engagement when role conflict is considered as a moderator. The moderated mediation models reveal that the indirect effect of autonomy and optimism on organizational citizenship behavior can be moderated by role conflict.
