Grit is defined as perseverance and passion for long-term goals, and it may affect the stability of the nursing workforce and the physical and mental health of nurses continuously. Meaning in life has received considerable attention from scholars, which is an important component in positive psychology. This study aimed to delve into the relationship between grit and the meaning in life of Chinese nurses. Additionally, we also sought to prove the chain mediating effect of social support and hope on this relationship. An online questionnaire survey was used to collect data from 704 Chinese nurses using the self-made demographic questionnaire with Short Grit Scale (Grit-S), the Perceived Social Support Scale (PSSS), Adult Dispositional Hope Scale (ADHS), and Meaning in Life Questionnaire (MLQ). Moreover, Process version 3.3 plug-in SPSS 25 was used to test the mediation effect between variables. The results showed a strong positive relationship between grit and meaning in life and verified the mediating effect of social support and hope on grit and meaning in life. The results also confirmed the chain mediating model between grit, social support, hope, and meaning in life.
Introduction
Since the 1950s, positive psychology has become increasingly prominent among scholars. Researchers pointed out that positive psychology should pay attention to positive mental status (i.e., positive emotions, positive environments, and positive attitudes) and other related concepts (Seligman et al., 2005; Moskowitz et al., 2019). Meaning in life, related to the ability of an individual to survive in the face of adversity, is a basic element of human existence (Frankl, 1966). Steger et al. (2008) noted that the key to meaning in life is to be aware of the current goal and ultimately achieve it. Nursing plays a paramount role in saving lives and promoting the health status of patients, as well as being the frontline workers in global health emergencies like the outbreak of the covid-19 pandemic. High role expectations and varieties of stressors caused a negative impact on the development of the careers of nurses (Tyer-Viola, 2019). Based on numerous demands for nurses, they are required to have a greater sense of responsibility and mission. Therefore, nurses must own a clear life goal, and strive to enhance the sense of meaning in life. The study of Czekierda et al. (2017) identified meaning in life as a potential role of physical health, with a mild to moderate positive impact. More studies had confirmed that meaning in life is positively correlated with the quality of life and self-esteem (Barnett et al., 2019; Bernard et al., 2020). Furthermore, meaning in life is an important predictor of subjective well-being (Krok and Gerymski, 2019) and is related to positive emotions, life satisfaction, and career decision self-efficacy (Sari, 2019). Meanwhile, researchers showed an insufficient sense of meaning in life may experience stressor-related distresses suicidal tendencies, and negative thinking (Barnett et al., 2019; Lew and Chistopolskaya, 2020; Ostafin and Proulx, 2020).
The Impact of Grit on Meaning in Life
When encountering challenges or disasters, nurses need to delve into high-quality patient care, retain resilience, and process professionally in the face of adversity continually (Brennan, 2017). Generally, a personality trait named grit drives nurses to complete the mission on difficult occasions (Meyer et al., 2020). Gritty people always adopt various strategies to achieve long-term goals and alleviate negative impacts in life (Blalock et al., 2015). Duckworth and Quinn (2009) categorized grit into consistent interest and persistent effort. The existing studies had confirmed that grit is an important non-cognitive trait of success or failure among nursing students (Terry and Peck, 2020), nurses (Tyer-Viola, 2019), or nurse leaders (Seguin, 2019). Grit was a significant predictor of nursing students in clinical and academic achievement, regardless of demographic factors (Terry and Peck, 2020). Researchers demonstrated that grit was associated with increased job involvement, greater career longevity, lowered turnover intention, and improved well-being for nurses and nurse leaders (Jeong and Seo, 2019; Seguin, 2019). Therefore, the study tried to hypothesize the following:
Hypothesis 1: Grit will significantly predict meaning in life (grit→ meaning in life).
The Mediating Role of Social Support Between Grit and Meaning in Life
Perceived social support implies that individuals experience a subjective feeling of being understood, respected, and supported by others (Liu and Aungsuroch, 2019). Social support was categorized as external (from friends and family) and internal (from colleagues and leaders) support (Hamama et al., 2019). Social support was regarded as motivation that improved job satisfaction and alleviated the work stress of nurses successfully (Orgambídez and Almeida, 2020). In the study of Nowicki and Ślusarska (2020), they indicated that peer support is an important risk factor for traumatic stress among nurses, especially facing major public health events. The work of Krause and Rainville (2020) suggested that social support mediated the relationship between age and meaning in life. In another study, Lee et al. (2017) discovered a significant relationship between the search for meaning and perceived social support. When receiving more social support, nurses can cope with the negative effects of stressful environments, stimulate enthusiasm for work, and improve their sense of meaning in life. Therefore, the study tried to hypothesize the following:
Hypothesis 2: Social support will act as a mediator between grit and meaning in life (grit→ social support→ meaning in life).
The Mediating Role of Hope Between Grit and Meaning in Life
Hope is a positive expectation of results (Scioli et al., 2011) and plays a vital role in clinical practice (Zhang et al., 2020). The broaden-and-built theory of positive emotions showed that hope can reduce the influence of negative emotions by constructing psychological resources (Fredrickson, 2001). Numerous studies have shown that hope reduces psychological distress, maintains adaptation to disease, improves well-being, and driving directions for existence (Mattioli et al., 2008; Rustøen et al., 2011). In addition, a high level of personal hope can divert their attention from negative events (Kaleta and Justyna, 2020), reduce the risk of depression and suicide, and improve meaning in life (Sun et al., 2021). Therefore, the study tried to hypothesize the following:
Hypothesis 3: Hope will act as a mediator between grit and meaning in life (grit→ hope→ meaning in life).
The Chain Mediating Role of Social Support and Hope on Grit and Meaning in Life
Many studies have suggested grit, social support, hope, and meaning in life were positively correlated with quality of life, job satisfaction, and well-being (Seguin, 2019; Bernard et al., 2020; Orgambídez and Almeida, 2020; Shiri et al., 2020). Nurses with grit can be combined with positive environmental factors represented by social support and positive attitudes represented by hope to tolerate stress, and improve quality of life, job satisfaction, subjective well-being, and finally enhance the sense of meaning in life. Therefore, the study tried to explore the following:
Hypothesis 4: Social support and hope will jointly act a chain mediator role in the relationship between grit and meaning in life (grit→ social support→ hope→ meaning in life).
Although previous studies have separately explored the relationship between grit, social support, hope, and meaning in life, few studies have shown how grit affects the meaning in life through the mediating role of social support and hope. Generally, only a few works of literature have focused on personality traits and meaning in the life of hospice nurses (Barnett et al., 2019), oncology nurses (Candela and Piredda, 2020), and pediatric nurses (Taubman-Ben-Ari and Weintroub, 2008). Therefore, this study intended to delve into the impact of the grit of Chinese nurses on the meaning in life from the perspective of positive psychology and analyze the mediating role of social support.
Materials and Methods
Participants
Since data collection was conducted at one specific time, the nature of this study was cross-sectional. The study group consisted of 756 nurses who were recruited from different hospitals in Chengdu City, China, who met criteria through an online questionnaire survey. Among the 756 nurses, 704 of whom were valid (52 nurses failed to complete all answers). The response rate was 93.12%. All participants had signed informed consent and voluntarily participated in this study. The inclusion criteria were: (a) obtained professional qualification certificate in the People’s Republic of China; (b) have at least 1-year working experience in clinical nursing or clinical nursing management; (c) no previous or current diagnosis of mental illness or drug or alcohol dependence; (d) had a basic phone or computer skills; (e) informed to participate in the study. Nurses who failed to complete the survey were excluded. The characteristics of the participants are shown in Table 1.
Table 1. Baseline characteristics and difference in the grit score of nurses.
Measures
All tests were conducted in Mandarin Chinese.
Demographic Variables
A self-made demographic questionnaire was utilized in this study to collect the characteristics of participants, including gender (male, female), age, educational background (college degree, bachelor’s, or graduate degree), and length of nursing work.
Grit
The self-reported Short Grit Scale (Grit-S) was developed and validated by Duckworth and Quinn (2009) including two subscales, namely, consistency of interest and perseverance of effort. A total of eight items in the scale were included and used the 5-point Likert scale (from 1 = “not like me at all” to 5 = “very much like me”). The Grit-S of the Chinese version has good reliability which had been verified by Li et al. (2018). The Cronbach’s α of the self-reported scale was 0.73–0.83 in a previous study (Duckworth and Quinn, 2009). In addition, the Cronbach’s α of subscales were from 0.58 to 0.71 in China (Wang, 2016).
Social Support
The 12-item Perceived Social Support Scale (PSSS) was developed and validated by Zimet et al. (1990), including three subscales (family support, friends support, and other support). Participants rated on a 7-point Likert response format (from 1 = “very strongly disagree” to 7 = “very strongly agree”). The total scores ranged from 12 to 84, with higher scores suggesting greater perceived social support. The Cronbach’s α for the PSSS was 0.914 in the current study (Liu et al., 2016).
Hope
The Adult Dispositional Hope Scale (ADHS) was originally designed by Snyder et al. (1991) and the Chinese version was applied and verified by Ren (2006). The ADHS may be applied to individuals older than 15 years to assess the dispositional level of hope. The scale consisted of 12 items, wherein 4 items (items 3, 5, 7, 11) served as fillers and were not interpreted. The other 8 items were divided into 2 dimensions, measuring pathways thinking (items 1, 4, 6, 8) and agency (items 2, 9, 10, 12). ADHS adopted a 4-point scoring method (from 1 = “definitely false” to 4 = “definitely true”). The Cronbach’s α of the scales was from 0.74 to 0.84 (Snyder et al., 1991).
Meaning in Life
The 10-item Meaning in Life Questionnaire (MLQ) was originally compiled by Steger et al. (2008), including two subscales, namely, the presence of meaning and the search for meaning. The Chinese version of MLQ was revised and verified by Wang et al. (2016). Participants rated on a seven-point Likert response format (from 1 = “completely inconsistent” to 7 = “completely consistent”). The Cronbach’s α of the two subscales was 0.88 and 0.93, respectively (Steger et al., 2009).
Procedure
The study was ethically approved by the Ethics Committee of Chengdu 4th Hospital and the registration number of the Chinese Clinical Trial Registry is ChiCTR1900020715. Nurses were asked to complete an anonymous online survey. Each hospital appointed an investigating nurse who had been trained by researchers previously. Participants had signed informed consent before the investigation and voluntarily participated in this study. Investigating nurse is requested to distribute the questionnaire to other nurses. Subsequently, nurses were invited to click on a web link1 to access the questionnaire via mobile phones. The investigating nurses explained the unclear and ambiguous items suggested by the participants during the field investigation according to the unified guidelines. Note that all questionnaires were self-rated, and participants filled separately.
Statistical Analysis
The following data analyses were used to verify the relationship between grit and meaning in life and verify the mediating effect of social support, and hope on grit and meaning in life. Note that the statistical description of the count data was represented by the composition ratio [n (%)], while the measurement data conforming to the normal distribution was represented by (M ± SD). Comparison between groups was represented by the t-test. Pearson correlation analysis was adopted between both factors of grit, social support, hope, and meaning in life. Process V3.3 in SPSS (IBM. V25.0) was used to analyze the mediating effect of social support and hope on grit and meaning in the life of clinical nurses. The bootstrap method was used to estimate the 95% confidence interval with 5,000 repeated sampling, and Two-sided inspection level α = 0.05.
Results
A total of 756 nurses were recruited in this study, with 704 nurses satisfying the necessary criteria. A majority of nurses were female (90.6%) and their average age was 31.79 (SD = 7.38) years. Almost half of the nurses (57.1%) possessed a bachelor’s or graduate degree. Their average length of nursing work was 10.72 (SD = 8.12) years (Table 1). However, there were no significant differences in the grit scores of nurses among different subgroups of gender, age, educational background, and length of nursing work (P > 0.05) (Table 1).
Correlation Analysis of Major Study Variables
Pearson correlation analysis showed that grit was positively related to social support (r = 0.407, P < 0.01), hope (r = 0.506, P < 0.01), and meaning in life (r = 0.455, P < 0.01). Similarly, social support was positively correlated with hope (r = 0.484, P < 0.01) and meaning in life (r = 0.546, P < 0.01). In addition, hope was positively related to meaning in life (r = 0.589, P < 0.01) (Table 2).
Table 2. Correlation analysis of study variables.
Multiple Mediating Analyses Between Variables of Clinical Nurses
The results showed the total effect (β = 0.456, t = 13.5, P < 0.001) and the direct effect (β = 0.142, t = 4.251, P < 0.001) of grit on the meaning in life were both significant, after controlling the variables such as gender, educational background, and length of nursing work. Grit significantly predicts social support (β = 0.408, t = 11.827, P < 0.001) and social support predicts meaning in life (β = 0.311, t = 9.402, P < 0.001), indicating that social support played a mediating role between grit and meaning in life. Similarly, grit significantly predicts hope (β = 0.367, t = 11.107, P < 0.001) and hope predicts meaning in life (β = 0.37, t = 10.459, P < 0.001) indicating that hope played a mediating role between grit and meaning in life. Meanwhile, social support can also predict hope (β = 0.338, t = 10.223, P < 0.001). Therefore, social support and hope had a chain mediating effect between grit and the meaning in the life of Chinese nurses (Table 3).
Table 3. Regression model of the effect of grit on meaning in life among Chinese nurses.
Results of the mediating effect analysis in Table 4 showed that Bootstrap’s 95% CI of total indirect effect did not contain 0 [Bootstrap 95% CI:0.258,0.374], accounting for 68.86% of the total effect. Importantly, three indirect effect pathways influenced the relation of grit and meaning in life. Firstly, mediating effect value of Path1 (Grit → Social Support → Meaning in Life) was 0.127 [Bootstrap 95% CI:0.09,0.166], accounting for 27.85% of the total effect. Secondly, mediating effect value of Path2 (Grit → Hope → Meaning in Life) was 0.136 [Bootstrap 95% CI:0.100,0.176], accounting for 29.82% of the total effect. Thirdly, the mediating effect value of Path3 (Grit → Social Support → Hope → Meaning in Life) was 0.051 [Bootstrap 95% CI:0.034,0.072], accounting for 11.18% of the total indirect effect. Note that the Chain mediating model is shown in Figure 1.
Table 4. Multiple mediated analysis between variables of nurses.

Pairwise comparison of the different indirect effects paths was adopted to verify whether these paths were significant different. The results showed that Comparison 2 [Bootstrap 95% CI:0.04,0.116] and 3 [Bootstrap 95% CI:0.047,0.116] were significant, except Comparison 1 [Bootstrap 95% CI: –0.067,0.053].
Discussion
A rigorous perusal of existing literature revealed that limited studies have investigated the relationship and specific pathways between grit and meaning in life among Chinese nurses. The present study adopted a chain mediating model to explore the influence of grit, social support, and hope on meaning in life in Chinese nurses. The results supported the hypotheses and verified the mediating role of social support and hope in the relationship between grit and meaning in life.
Interestingly, a key finding of this study was grit had a significant positive effect on meaning in life, after controlling for gender, educational background, and length of nursing work. These results strengthen the relationship between grit and meaning in life (Oriol et al., 2020). We extended this conclusion to Chinese nurses. Nurses were increasing due to the development of health services in China (Zhao and Zhang, 2015). While nurses were confronted with more and more work and psychological pressure because of the huge influx of illness patients, workplace violence (Lu et al., 2019), and insufficient resources for health services, such as shortage of beds and the imbalance between medical staff and patients (Zeng et al., 2013). Individuals with higher grit do not seek immediate satisfaction and success but strive to achieve their goals after years of unswerving efforts (Duckworth et al., 2007). In the study of Sharkey et al. (2017), they indicated that grit positively correlated to health-related life quality among adolescents and young adults. In addition, there was a positive relationship between grit and life satisfaction, with self-esteem as the mediator variable in employees (Li et al., 2018). The work of Vainio and Daukantaitë (2016) implied that grit was positively related to well-being and mediated by a sense of coherence and authenticity. Thus, grit could play a positive role in promoting quality of life and meaning in life.
Furthermore, social support, hope, and meaning in life were both positively correlated, had been proven in many studies (Mahon and Yarcheski, 2017; Cao and Zhou, 2021; Torregrosa-Ruiz et al., 2021). The work of Bruhn and Philips (1987) noted individuals generated hope by seeking help from trustworthy people, which meant hope was given and received in a supportive relationship. Similarly, Russinova (1999) stated hope occurred with the support of family, parents, friends, and peers. The study of Lin et al. (2020) suggested that social support and meaning in life were associated with the life satisfaction of people. Researchers indicated people with social support and the presence of meaning in life were fewer negative effects and were less susceptible to mental illness (Lin et al., 2020; Cao and Zhou, 2021). Karataş et al. (2021) pointed that meaning in life and hope were significant predictors of life satisfaction. In addition, Snyder (2002) stated that hope, as an important psychological fore, turned stress into motivation with a positive impact on life satisfaction.
Another important finding is the chain mediating effect of social support and hope in the relationship between grit and meaning in the life of Chinese nurses. This is the main theoretical contribution of this research. The results showed grit indirectly affects meaning in life through three pathways: social support, hope, and the chain mediating effect of social support and hope. Previous studies demonstrated the partial mediating effect of social support in the relationship between resilience and the quality of life (Zhang et al., 2017). The current study demonstrated social support played a partial mediating role in the correlation between grit and the meaning in life (Path 1), accounting for 27.85% of the total indirect effect, which means that grit and social support are important predictors in the meaning of life. Social support is one of the most common positive external sources for coping with negative psychological events and has been widely cited as a protective factor of psychosocial adaptation (Oexle and Sheehan, 2020). The study also confirmed the mediating effect of hope underlying grit and meaning in life relationships (Path 2), accounting for 29.82% of the total indirect effect. It can be found that the mediating role of hope is greater than social support. Hope is a vital psychological resource, which is of great significance for building values and achieving success. Nurses with brave and gritty can increase motivation to attach goals, raise the level of hope, and eventually generate a sense of meaning. Finally, there existed another insignificant path (grit → social support → hope → meaning in life) (Path 3), accounting for 11.18% of the total indirect effect, which showed grit influenced the meaning in life through social support and hope. Social support and hope jointly promote meaning in life. Under tremendous work and psychological pressure, improvement of the sense of meaning in life contributes to reduce negative emotions and improve the quality of life and well-being of nurses.
The study enriches the content of positive psychology and deeply explores the mechanism of grit on meaning in life from the perspective of Chinese nurses. It turns out that social support and hope have an important role in the relationship, which provides a useful reference for the construction of a structural model of grit in the future.
Conclusion
Grit is an essential trait for the challenging profession of nursing. Some insights were provided into the relationship between grit and meaning in the life of Chinese nurses. This study demonstrated the relationship between grit and the meaning in the life of Chinese nurses and the mediate effect of social support and hope on grit and meaning in life. Specifically, the results gave evidence to infer that grit has a positive correlation with social support, hope, and meaning in life. Moreover, grit might directly or indirectly affect meaning in life through social support and hope. Based on the mediate effects, Path 1 and Path 2 played an important role in the total indirect effect. In conclusion, grit positively affected Chinese nurses to increase their levels of social support, hope, and meaning in life.
Limitations
There were several limitations in the current study. Firstly, the results were based on an online self-reported survey, which was highly prone to inaccurate and biased responses from participants. Secondly, this study was cross-sectional in design and impossible to clarify the causal relationship between the variables. Longitudinal research should be designed to supplement and verify the validity and reliability of our findings. Thirdly, the mediation variables in this research were social support and hope, while other variables might mediate grit and meaning in life. Finally, interactions between social support and hope were not analyzed and reported in this research.
