Personal Factors and Clinical Learning Environment as Predictors of Nursing Students' Readiness for Practice: A Structural Equation Modeling Analysis

Open AccessPublished:February 05, 2023DOI:https://doi.org/10.1016/j.anr.2023.01.003

      Summary

      Purpose

      It is essential to ensure the readiness for practice among undergraduate nursing students since the purpose of such education is to cultivate competent nurses who deliver high-quality and safe nursing. Astin's theory of student involvement suggests that this is affected by their personal factors and learning environment.

      Methods

      We conducted a cross-sectional study between November 16, 2020 and December 21, 2020 which examined personal factors and aspects of the clinical learning environment among senior nursing students (n = 838) enrolled across 54 nursing schools in Korea. The participants were asked to fill out a self-administered online survey, which assessed demographic characteristics, self-esteem, depression, work-life balance, clinical learning environment, anxiety during clinical practicum, and readiness for practice. Readiness for practice was measured using the Casey-Fink Readiness for practice survey. We used structural equational modeling to test our hypothetical model.

      Results

      The nursing students' readiness for practice was significantly affected by their self-esteem, work-life balance satisfaction, and clinical learning environment. Anxiety during clinical practicum directly influenced their readiness for practice.

      Conclusion

      Increasing self-esteem and work-life balance satisfaction, and improving their clinical learning environment by providing sufficient educational and clinical support, could help facilitate the transition from nursing schools to real-world practice for nursing students.

      Introduction

      Nursing students constitute a future healthcare workforce that will be tasked with safeguarding the health and well-being of all people. The cultivation of competent nurses is critical, particularly owing to the high prevalence of global health crises such as the COVID-19 pandemic. Preparing nursing students for clinical practice is a goal shared by nursing educators and administrators in clinical practice and academia [

The specific factors of interest included self-esteem, depression, and satisfaction with WLB, clinical learning environment, and anxiety during clinical practicum.

      Hypothesized model

      A hypothesized model was derived from Astin's theory [

      Astin's [

      ] student involvement theory research discusses students' college experiences and how these experiences play a role in changing and developing students over time. With numerous factors influencing academic achievement and social involvement through these experiences, Astin used the critical elements of student inputs (I), the educational environment (E), and student outcomes (O) to create a model for identifying such variables. In this model, “input” variables refer to the characteristics of students on school entry. The “environment” refers to the college context, including institutional aspects or student experiences while attending college. Finally, “outcome” refers to students' academic performances or degree attainment. One notable example is the work of Thomas et al. [

Their quantitative study revealed that increased depressive symptoms, antisocial behaviors, lower social support, and school participation were consistently related to decreased college retention. Consequently, Thomas et al. [

      ]. Assessing nursing student's personal characteristics, including psychological health, can help nursing programs understand how the educational environment affects students' readiness for practice in a more integrated manner. Therefore, in this study, input referred to personal factors, including their self-esteem, depression, and satisfaction with WLB. Environment referred to their clinical learning environment and anxiety regarding clinical practice. Outcomes include their readiness for practice. We hypothesized that these personal factors affect readiness for practice through their clinical learning environment and anxiety during clinical practicum (Figure 1).

      Methods

      Design and participants

      In this cross-sectional study, a total of 842 senior nursing students from 54 nursing schools with 4-year baccalaureate programs participated. Inclusion criteria were (1) senior nursing students aged 20–29 years to include Generation Z students (generally referring to those born between 1997 and 2012) [

      ], (2) expected to graduate in February 2021, and (3) expected to take the national nurse licensure examination in 2021. Data of four participants were excluded due to incomplete responses or the inclusion criteria not being met, and our final sample thus comprised 838 participants. The sample size used for the structural equation modeling (SEM) in the study was calculated based on the condition that the ratio of the sample size to the parameters should be no less than 10:1 [

      ]. Therefore, the total sample size was suitable for testing a model with 49 free parameters, which would necessitate the inclusion of at least 490 participants.

      Measurements

      A self-administered questionnaire with 81 items was used. After getting authors' approval for all measures of the study, a committee translation [

      Demographic characteristics

      The general characteristics queried included participants' age, gender, type of nursing school, other degrees, school locations, the reason for joining nursing school, and employment expectations.

      Personal factors

      ] and .80 in this study. Each item was rated on a 4-point Likert scale that ranged from 1 (strongly disagree) to 4 (strongly agree). The overall mean is considered the scale score, and higher scores indicated higher levels of self-esteem. The overall mean score of self-esteem was used for the correlation analysis with other variables. In the SEM, item parceling was performed using the “item-to-construct balance” technique to obtain more stable parameter estimates and better model fit. Item parceling was used by averaging item scores in each parcel and generating parcel scores as indicators of latent variables [

Each item was rated on a 5-point Likert scale that ranged from 1 (strongly disagree) to 5 (strongly agree), and the total score (range, 5−25) was calculated by adding the scores of each item. A score of 5−17 is considered normal, whereas ≥18 indicates dysfunctional depression. The total score of the five items was used in the correlation analysis. We used the total score as an observed variable in the SEM.
      WLB was assessed using two items–one for WLB proportion and the other for WLB satisfaction. WLB proportion was measured using the WLB Charter by the Japanese Cabinet [

Each item was rated on a 5-point Likert scale that ranged from 1 (“entirely disagree”) to 5 (“entirely agree”), and higher scores indicated that the students perceived their clinical learning environment to be more positive. The Cronbach's alpha of the Korean version of the CLES + T for the overall scale was .94, and the subscales ranged from .78 to .94. [

As a latent variable in the SEM, anxiety during clinical practicum had two indicators, corresponding to the average scores of the two subscales.

      ]. This 20-item self-report questionnaire was used to measure the confidence and comfort to providing nursing care among the participants. The questionnaire contained four subscales: clinical problem solving, learning techniques, professional identity, and trials and tribulations. The instrument underwent committee translation and was validated through a CFA. Based on the validation result, we used the four original subscales, and the items were rated on a 4-point Likert scale that ranged from 1 (“strongly disagree”) to 4 (“strongly agree”). The mean of all items was considered scale score, and a higher score indicated better readiness for practice. The Cronbach's α for the overall scale was .69 and the subscales ranged from .50 to .80 at the time the instrument was developed [

      ]. The Cronbach's α was .89 for the total scale and .50 to .76 for the subscales in the present study. The overall mean scores of the readiness for practice were used for the correlation analysis with the other variables. As a latent variable in the SEM, readiness for practice had four indicators: the mean scores of the four subscales.

      Data collection

      For data collection, we selected nursing schools using convenience sampling and asked them to distribute the study flyer online and offline to their students. Students interested in the study participated by accessing the New Nurse e-cohort study website (http://newnurse.or.kr). All participants were asked to complete the survey after carefully reading the explanation on the first page of the online survey link, stating the purpose and content of the study, non-collection of personally identifiable information, confidentiality, and anonymity, and right to withdraw from research participation. Each participant was provided with a small incentive of approximately $16. Data were collected using the online survey, which took 10–20 minutes to complete. The item non-response rate was minimized because the online survey did not proceed to the next question until the current one was answered. The data collection was conducted from November 16, 2020 to December 21, 2020.

      Data analysis

      SPSS Version 26.0 (SPSS Inc., Chicago, IL, USA, 2019) was used to conduct statistical testing, including a description of the data, correlation analysis, and the calculation of reliability estimates. To explore the impact of personal factors, and clinical learning environment on the readiness for practice among senior nursing students, SEM as implemented in AMOS Version 26.0 was used to test the model hypothesized in this study.
      In this study, univariate normality was satisfied, and even if multivariate normality was not satisfied, parameter estimation was performed with the maximum likelihood method according to the report that the estimated parameters are reliable if the maximum likelihood method is used [

      ]. Maximum likelihood estimation was used to estimate the model, and the bootstrap resampling technique was used in the SEM to obtain more stable and valid standard errors of the estimates. Multivariate normality reported a multivariate kurtosis value of 32.712 in AMOS, and multivariate normality was not satisfied because it exceeded the critical value. Path analysis was used to identify both the direct and indirect effects in the model. The direct, indirect, and total effects of the variables in the model are presented in Supplementary Table 1. The model fit was assessed using the following indices, i.e., relative chi-square (x2/df) test <5.00 [

      Results

      Students' general characteristics

      Of the total of 842 participants, 838 were used for the final analysis, excluding two born before 1997 and two with careless responses. The average age of the participants was 22.9 ± 1.4, and women students accounted for 90.6% of the sample (Table 1). In total, 82.6% of the participants were enrolled in university, and only 4.4% of them were pursuing a second degree. The high employment rate after graduation (39.5%), as well as academic interest and aptitude (33.9%), were the major reasons for the participants joining nursing schools. Most (88.4%) of the students are expected to be employed. A majority (54.2%) of the participants spent >50.0% of their time on work (Table 1).

      Descriptions and factor loadings of study variables

      The participants' perceived readiness for practice was at a moderate level (2.86 ± 0.31) (Supplementary Table 2). In total, 86.8% of the participants responded to questions on the CFRPS with “agree” or “strongly agree,” which indicated that they were ready for practice. Learning technique and professional identity were the subdomains with the highest scores (2.94 ± 0.54 and 2.94 ± 0.43, respectively), whereas trials and tribulations received the lowest (2.73 ± 0.35). Self-esteem was at a moderately high level (3.23 ± 0.45). The mean score of depression among students was 10.85 ± 4.12, and only 7.0% of the students were assessed to be experiencing dysfunctional depression (scores >18). The participants displayed a moderate level of WLB satisfaction (2.82 ± 0.63).
      The students perceived their clinical learning environment as moderate (3.14 ± 0.67). Role of nurse teacher (3.79 ± 0.82) was the subdomain that received the highest score, whereas pedagogical atmosphere in the ward (2.82 ± 0.81) received the lowest score. Their anxiety during clinical practicum was at a moderate level (2.84 ± 0.70).
      Students felt more anxious about communication and the procedural aspects related to patients (2.90 ± 0.89) compared to interactions with faculty (2.81 ± 0.71). The CFA results are reported in Supplementary Table 2. The values of the factor loadings ranged from .440 to .874 (>.40), showing that the latent variables were measured comprehensively by their observed indicator variables [

      Correlations of study variables

      A correlation matrix was prepared before testing the hypothesized model (Supplementary Table 3). Self-esteem (r = .42, p < .001), WLB satisfaction (r = .34, p < .001), and clinical learning environment (r = .40, p < .001) were positively correlated with readiness for practice. In contrast, depression (r = −.23, p < .001) and anxiety during clinical practicum (r = −.50, p < .001) were negatively associated with readiness for practice. Their correlation coefficients were less than .70, which is the criterion for questioning multicollinearity [
      • Cheung G.W.
      • Wang C.

      ]. The Variance inflation factor (VIF) value of 1.7 or less confirmed no multicollinearity between all variables.

      Test of the hypothetical model and parameter estimates

      The modified model's goodness of fit with the research variables was x2/df = 4.888 (<.001), GFI = 0.950, CFI = 0.941, and root mean square error of approximation= 0.068. Thus, the modified model fit the data. Through the modifications, the difference between the Chi-square of the hypothesized model and the third modified model [x2 = 98.281 (411.118 − 312.837), df = 3 (67 − 64)] is larger than 18.55 and in the range of p = 0.005, the modified model may be considered significant and be adopted in place of the hypothesized model [

      ], and also, CFI improved from .918 to .941 (Supplementary Table 1). A fully adjusted model that controlled for all the participant characteristics (age, gender, type of school, second degree students, location of school, reason for joining nursing school, expected employment) was also tested, and the effects among the study variables were consistent with the unadjusted hypothetical model. For simplicity, we have reported the unadjusted results in this paper. The final model is presented in Figure 2. After checking the modification indices, within-factor correlated measurement was allowed, and the model fit indices improves compared to the previous model.

      Table 2, Table 3 summarize the final model's standardized direct, indirect effect, and total path estimates. There were significant direct and indirect effects associated with the personal factors, environment factors, and readiness for practice. Higher self-esteem (β = .29, p < .001), higher WLB satisfaction (β = .12, p < .001), and better clinical learning environment (β = .30, p < .001) were directly associated with better readiness for practice. Conversely, lower anxiety during clinical practicum was directly related to better readiness for practice among nursing students (β = −.36, p < .001). In addition, higher self-esteem (β = .19, p < .001) and higher satisfaction with WLB (β = .25, p < .001) were associated with a better clinical learning environment. The clinical learning environment significantly influenced the nursing students' readiness for practice through anxiety during clinical practicum. A better clinical learning environment was associated with lower anxiety during clinical practicum (β = −.37, p < .001), which resulted in better readiness for practice. Self-esteem indirectly influenced readiness for practice through clinical learning environment, anxiety during clinical practicum sequentially (β = .02, p = .001). Self-esteem also indirectly influenced readiness for practice through clinical learning environment (β = .06, p = .001). WLB indirectly influenced readiness for practice through clinical learning environment, anxiety during clinical practicum sequentially (β = .03, p < .001). WLB also indirectly influenced readiness for practice through clinical learning environment (β = .08, p = .001). Depression had no direct or indirect effect on readiness for practice. The model estimated a 49.7% variance in the readiness for practice of nursing students.

      Discussion

      The findings of this study generally supported our hypothesized model, even though some paths were not significant. We observed that readiness for practice was directly and indirectly affected by self-esteem, WLB satisfaction, and clinical learning environment.
      Anxiety during clinical practicum also directly influenced readiness for practice. These findings provided a more comprehensive picture of how personal factors and clinical learning environment are related to the readiness of nurses for practice, driven by anxiety during clinical practicum. However, given the weak-to-moderate effects of the examined variables, further research is needed to explore more factors related to readiness for practice among nursing students.
      We used the comfort and confidence section of the CFRPS after the validation process to measure readiness for practice, new graduate nurses have reported that a lack of clinical confidence impedes their transition to clinical practice [

      Our findings further revealed that as personal factors, both self-esteem and WLB satisfaction had a specific indirect effect on readiness for practice through the clinical learning environment and the anxiety during the clinical practicum. This finding is supported by the previous study, which reported that lower self-esteem has significant adverse effects on perceiving both themselves and the clinical learning environment, provoking defensive behavior and poor communication, resulting in negative clinical practicum achievements among nursing students [

However, only 7% of the participants in the study had dysfunctional depression, which meant that most students do not experience depressive symptoms. A possible reason for this result is that there is a possibility of assessing depression inaccurately in practice although SFNDS has been a relatively reliable and proven tool. Whether the dysfunctional depression identified using the SFNDS is consistent with the actual clinical diagnosis has not fully established [

      A notable finding of this study was that, among all variables, the clinical learning environment had the most significant effect on the readiness for practice. Specifically, the clinical learning environment had a direct effect on the readiness for practice for nursing students; moreover, it indirectly affected the readiness for practice through the anxiety during clinical practicum. The more positively the students perceived their clinical learning environment, the lower their anxiety during clinical practicum, which in turn indicated better readiness.

First, our findings must be viewed with caution as most participants were female and from universities located in urban areas due to the convenient sampling method employed. Second, we measured readiness for practice using a self-administered survey based entirely on the students' perspectives. Readiness for practice should be evaluated by the student, nursing faculty, and nurse educators in practice as they have different lenses through which they view practice readiness. Additionally, this study was cross-sectional, limiting our understanding of the influence of personal and environmental factors on readiness for practice based on the I-E-O model [

      ]. A longitudinal study may be conducted to better explore relationship between factors and understand the association between analyzed variables. Lastly, we modified the standardized instruments with multiple subdomains into shorter versions to suit the purpose of our study. This may have hindered us from attaining an in-depth understanding of the concepts and limited the comparisons that could be made with other studies that explored readiness for practice. While the readiness for practice instrument maintained the same construct as the original instrument, Cronbach's alpha value was .5 in learning techniques, one of the sub-domains, which was not ideal but was acceptable [

      ]. Although this is the same result as the original instrument when developed, a psychometric test for the Korean student nursing population is proposed in follow-up studies to secure validity and reliability.

      Conclusions

      Our findings suggest that taking personal factors into account, improving their clinical learning environment, and providing sufficient educational and clinical support could enable nurses to establish better professional values and readiness for practice. In addition, considering the characteristics of Generation Z, where individual values and characteristics are becoming increasingly important, the cooperation among nursing schools, teaching hospitals, and clinical learning institutions toward providing clinical learning curricula reflecting generational characteristics can effectively improve readiness for practice among nursing students. This would effectively help ensure readiness for practice so that graduates can transition to professional nurses.
