In this study, the work readiness scores higher than the results of the survey of newly graduated nurses by Li et al. [31]. The difference may be due to the fact that most of the respondents in this study work in tertiary hospitals with higher management level. Before the entry of new nurses, hospital managers will conduct induction training for them. In this process, the managers pay more attention to the cultivation of practical skills and social abilities of new nurses, so the participants have a relatively high degree of work readiness. Participants’ professional identity scores were slightly higher than the findings of Zhou et al. [69]. Different from experienced clinical nurses, new nurses, as newcomers to the workplace, may have higher enthusiasm in the process of translating theory into practice, and they can get care and help from colleagues and teachers, which helps new nurses to familiarize themselves with job responsibilities and maintain their love for the profession, thus promoting their professional identity. Participants’ organizational justice scored slightly higher than previous findings [70], The difference in results may be due to the fact that their subjects were all staff members (including physicians, nurses, technicians, clerks, and other staff) of this hospital in Lazio, Italy, whereas our subjects were only new nurses. New nurses starting their careers have a higher level of trust in the organisation and are likely to experience fewer incidents of injustice; it may also be related to differences in traditional culture. Work performance scored was lower than in the study by Li et al. [71], which may be due to the fact that new nurses are not familiar with the department environment, rules and regulations and work habits, and lack rich work experience and problem-solving ability, so their work performance is slightly lower.
This study found that new nurses’ work readiness had a significant positive impact on work performance, confirming Hypothesis 1. This is because when new nurses have higher work readiness to enter the post, they will have more comprehensive work ability, which may enable them to experience less transition shocks and enhance confidence, and make them more enthusiastic to work [31, 72], thus improving work performance. The above results show that we should strengthen the awareness of the importance of work readiness for new nurses. Universities can set up relevant courses and training to improve nursing students’ professional skills and social ability, and organize campus activities to simulate clinical work scenes, so that they can better understand their future work content and procedures, and strengthen their work readiness. Nursing managers should pay attention to the intensive training of new nurses’ professional skills, and hold lectures to cultivate new nurses’ social skills, so that they can improve their communication skills with colleagues, leaders, patients and their families, which can improve the level of work readiness.
This study found that professional identity was a mediating variable for work readiness and work performance of new nurses, validating Hypothesis 2. When new nurses were well prepared for work, their role perception, interpersonal relationships, care responsibilities, and knowledge and skills were significantly improved [62]. When they recognize their profession, their personal value can be reflected in the career they are willing to fight for [73, 74]. Professional identity can help nurses actively engage clinical work, which has a positive impact on work performance [45]. This result suggests that we should strengthen the fostering of new nurses’ professional identity, nursing educators can pass on professional values to students through formal classroom teaching and after-school communication and guidance. Clinical teachers should be role models to guide new nurses to closely combine their own development with the nursing profession and enhance their professional identity.
This study found that organizational justice was a mediating variable for work readiness and work performance of new nurses, validating Hypothesis 3. When new nurses have a high level of work readiness, it helps them to understand fair behavior within the organization [55], and helps them to be adaptable and flexible in dealing with patients and colleagues, which helps to strengthen interpersonal justice [56]. Nurses with a high sense of organizational justice are more inclined to invest and contribute, more focused on job and pay more attention to personal growth and work performance [52]. Conversely, new nurses lack of experience and large mental fluctuations, when feeling unfair treatment, doubt and even distrust the organization and reduce work passion [50], thus having a negative impact on performance. This result reminds nursing managers that they should create a good and fair atmosphere, help new nurses establish the correct concept of pay and return, make reasonable explanations on decision-making or distribution at the appropriate time, and make transparent policies, so that they can better take initiative in work and improve work performance, and achieve a good and stable circular development.
This study found that professional identity was a mediating variable of organizational justice and work performance of new nurses, validating Hypothesis 4. According to the cognitive-emotional theory, individual cognition and emotional response mainly come from the role of situational information, and then activate individual behavior decisions [75], this suggests that open and transparent decision-making and management will help individuals to fully understand the distribution process [62] and strengthen the individual trust and identity of the organization, so that they are willing to contribute to the organization, even to improve their professional thinking and ameliorate poor behavior tendency [76], which positively affect the staff’s work performance. The results showed that hospitals should establish reasonable salary standards, create a more equitable environment and performance appraisal system, fully consider the rationality of distribution, and let new nurses know the salary adjustment and job promotion information of the hospital, which is of great significance to improve their sense of organizational justice, professional identity and work performance.
5.1 Limitation and future research direction
Firstly, this study only investigated some of the newly recruited nurses in five hospitals in Henan Province, and the number of interviewees was small and concentrated in one region. Therefore, future studies could expand the sample source and adopt a multi-centre survey method for different regions to improve the generalizability of the study. Secondly, this study is a cross-sectional study, which cannot explain the causal relationship well, and in the future, longitudinal study combined with interdisciplinary approach should be adopted to understand the dynamic process of nurses’ psychological changes. Third, this study collected data by subjectively filling out a questionnaire, which is easily influenced by the social expectation effect, and future studies could adopt a more objective approach and study from multiple perspectives. Finally, another limitation relates to the potential role of personality traits in influencing employee performance, as a study by Iliescu et al. [77] found that extraversion and agreeableness’ persons predicted their job performance. Thus, future research could explore the role of personality traits in work readiness and work performance.
