Abstract: Hospital nurses frequently experience relationships with patients as stressors in the workplace. Nurses’ coping behavior is one potential buffering factor that can reduce the effects of job stress on their psychological functioning and well-being. In this study, the association between nurses' strategies for coping with interpersonal stress from patients and their psychological distress was examined. Participants included 204 hospital nurses and 142 salespeople, who were used as a comparison group. Participants completed measures of coping with interpersonal stress and psychological distress. Hospital nurses reported more psychological distress than did salespeople. Moreover, distancing coping was correlated with high psychological distress in both nurses and salespeople, and reassessing coping was correlated with low psychological distress in nurses. For nurses only, constructive coping appeared to be an effective strategy for reducing psychological distress. It is important for nurses to understand the role of constructive coping in nurse–patient communication and interaction.

Introduction

Previous studies have reported that nurses encounter multiple and ubiquitous stressors in the workplace,13 including work overload, shift patterns, lack of confidence in their efficacy as nurses, uncertainty about treatment, conflict with physicians/supervisors/peers, and feelings of powerlessness. Such work-related stressors have a negative impact on the quality of care patients receive, as well as nurses’ well-being, health, and work adaptation.27 For example, an analysis of data obtained from the Nurses’ Health Study in the United States revealed that the relative risk for suicide among highly stressed female nurses compared to nurses with low work stress was 1.9 (95% confidence interval [CI]: 0.8–4.7).8 In a review of studies on turnover in hospital nurses, Coomber and Barriball, in 2007, suggested that work-related stressors are associated with less job satisfaction, work shortage, higher rate of absence, and poor performance and efficiency.9 Thus, hospital nurses’ experiences are important not only for patient care, but also for nurses themselves. Therefore, the present study evaluated how nurses coped with stress, particularly that originating from their relationships with patients, and the efficacy of their strategies in reducing subsequent psychological distress.

Nurses’ relationships with patients

The present study focused on nurses’ relationships with patients as a source of work-related stress. Stress from interactions with patients is salient in nurses’ lives.1015 For example, Mariam et al found in 2012 that 60.8% of female nurses reported that quick-tempered patients were a primary source of work-related stress.16 Moreover, McGrath and Boore reported in 2003 that 27% of a sample of nurses in Northern Ireland reported that the emotional demands of patients were a source of moderate to high levels of stress.17 Indeed, interpersonal stressors originating in relationships with patients can have a strong effect on nurses’ psychological distress,18,19 burnout,20,21 and job satisfaction.15,19 In addition, previous research has revealed that interpersonal stressors stemming from relationships with patients are related to emotional labor.22,23 Therefore, it is important for nursing researchers to investigate relationships with patients as a work-related stressor.

Coping behavior

According to the transactional theory proposed by Lazarus24 and Lazarus and Folkman,25 coping behavior is defined as “constantly changing cognitive and behavioral efforts to manage specific external and/or internal demands that are appraised as taxing or exceeding the resources of the person.”24 This theory postulates that coping behavior affects well-being and adaptation,24 and the validity and utility of this hypothesis has been supported by numerous studies.24 For example, the National Institute for Occupational Safety and Health (NIOSH) job stress model suggests that coping behavior is one potential buffering factor that reduces or eliminates the effects of job stress on psychological and physiological homeostasis or stress-related illnesses.26 As a result, research on coping has received considerable attention in clinical research and practice.27

In addition, coping behavior has also received attention from nursing researchers.2,28,29 For example, in a study of female hospital nurses,30 it was reported that affective-oriented coping was significantly associated with depressive symptoms, even after controlling for the effects of job stress, nursing-related work experience, and social support. Moreover, a study of hospital nurses in Australia and New Zealand found that type of coping strategy was significantly associated with physical and mental health, after controlling for the effects of job stress, years as a nurse in the current clinical unit, and income.31 Finally, Günüs¸en and üstün also reported, in 2010, that burnout among nurses is reduced when coping skills training was provided.32

Coping with interpersonal stressors

Kato, in 2013, proposed three coping strategies for dealing with interpersonal stressors: distancing coping, reassessing coping, and constructive coping.33 Distancing coping refers to strategies that attempt to actively damage, disrupt, or dissolve a stressful relationship (eg, avoiding contact with the person, ignoring the person). It is possible that distancing coping leads to poor interpersonal relationships in the workplace. The deterioration of interpersonal relationships at work can also result in psychological and physiological dysfunctions.34 In samples of Japanese students,33 distancing coping was found to be positively and significantly correlated with psychological dysfunction, such as depressive symptoms, anxiety, and general psychological strain. On the other hand, reassessing coping incorporates efforts to patiently wait for an appropriate opportunity to act, such as a change or improvement in the situation (eg, taking a pragmatic view of the matter, deciding not to take the matter seriously). In samples of Japanese students,33 reassessing coping has been negatively and significantly correlated with psychological dysfunction. Finally, constructive coping involves actively seeking to improve, maintain, and/or sustain a relationship without aggravating the other individuals (eg, reflecting on one’s own conduct, trying to understand the other person’s feelings). This strategy emphasizes respecting others and maintaining harmonious relations. It is important for nurses to learn to cope with their relationships with patients as a work-related stressor, in order to decrease the negative effects on their well-being. To this author’s knowledge, however, no study has examined the relationship between coping with interpersonal stressors and psychological dysfunction in nurses.

In the present study, the association between nurses’ coping strategies used to deal with stress stemming from relationships with patients and resultant psychological distress were examined. In addition, the study aimed to uncover how nurses’ coping responses compared with those in other industries with high levels of interpersonal stress; therefore, nurses’ coping strategies and psychological distress were compared with those of department store salespeople. Previous research has shown that, as with nurses, salespeople are exposed to frequent potential interpersonal stressors in the workplace (eg, multiple interactions with customers),35,36 and has emphasized burnout and emotional exhaustion as important consequences of such stress.37,38 Therefore, salespeople were regarded as a suitable control group in the present study.

Methods

Participants and procedures

Two hundred and four hospital nurses and 142 salespeople participated in this study. All participants were Japanese and female. The mean age of the nursing sample was 29.89 years (range: 19–57 years; standard deviation [SD] =9.28), and the mean number of years working at hospitals was 9.12 (range 2–40 years). All salespeople were full-time department store workers, with a mean age of 34.20 years (range: 18–52 years; SD =10.75). Participants were recruited through short courses in stress management. The short course for nurses was hosted by a local nurses’ association as job training. The short course for salespeople was hosted by the human resources department of the firm at which they were employed. Participation in the training was voluntary for both samples. The study survey was administered before the training. After signing an informed consent form, all participants completed a set of questionnaires in a group setting. All participants received a pen valued at 100 yen (approximately 1.25 USD) in exchange for completing each survey.

Instruments

All measures, originally written in English, were independently translated into Japanese by three native-speaking Japanese psychologists. They were then back-translated into English by a native English-speaking psychologist. After back-translation, the original and back-translated questionnaires were compared for discrepancies. The translated questionnaires were modified after a discussion between the translators.

Coping with interpersonal stressors

The Interpersonal Stress Coping Scale (ISCS)33 was used to measure coping with interpersonal stress. The ISCS consists of three subscales: distancing coping, reassessing coping, and constructive coping, each consisting of five items. In the present study, ISCS items were slightly modified for use with nurses and salespeople. For example, the item “tried to understand the other person’s feelings” was modified to “tried to understand the patient’s feelings” for the nurses, and to “tried to understand the shopper’s feelings” for the salespeople. The participants were asked to rate the extent to which they used each item to deal with the patient or shopper on a 4-point Likert scale ranging from 0 (did not use) to 3 (used a great deal). The Cronbach’s alphas for the nurse and salesperson samples in the present study were 0.795 and 0.734 for distancing coping, 0.842 and 0.780 for reassessing coping, and 0.770 and 0.738 for constructive coping, respectively.

Psychological distress

The 12-item General Health Questionnaire (GHQ-12),39 designed as a general measure of health and psychopathology, used to measure psychological stress. The GHQ-12 is a self-report scale that has established reliability and validity.40 Participants were asked to report about their experiences within the past week on a 4-point Likert scale ranging from 0 (much less than usual) to 3 (better than usual). Cronbach’s alphas in the present study were 0.904 and 0.878 for nurses and salespeople, respectively.

Data analysis

We provided three types of effect sizes: Cohen’s d, Pearson’s r, and Cohen’s q. According to Cohen,41 small, medium, and large effect sizes correspond to d-values of 0.20, 0.50, and 0.80; R-values of 0.10, 0.30, and 0.50; and q-values of 0.10, 0.30, and 0.50, respectively. Cohen’s d is an effect size measure for t-values and Cohen’s q is an effect size measure for differences in correlation coefficients. All analyses were conducted with PASW Statistics (v 18.0.0; IBM Corporation, Armonk, NY, USA) and R software (v 3.0.1; The R Foundation for Statistical Computing, Vienna, Austria). Effect sizes and confidence intervals were calculated using the R software.

Results

Between-sample differences in coping strategies and psychological distress

Table 1 presents the means and SDs for coping strategies and psychological distress scores. Between-subject Student’s t-tests were conducted to compare coping strategies and psychological distress scores in nurses and salespeople. The results revealed that the nurses reported higher psychological distress (mean =9.44, SD =6.43) than the salespeople (mean =7.84, SD =7.49, t[344] =2.13, P<0.05, 95% CI: −3.08 to −0.12, d=0.23). There were no significant differences between the samples in terms of coping strategies; however, the mean scores for all coping strategies were higher for nurses than for salespeople (P<0.10).

Correlations between coping strategies and psychological distress

The correlation coefficients between coping strategies and psychological distress are shown in Table 2. Distancing coping was significantly correlated with high psychological distress for nurses (r[202] =0.235, P<0.001) and salespeople (r[140] =0.207, P<0.05). Reassessing coping, however, was significantly correlated with low psychological distress for nurses (r[202] =−0.224, P<0.001), but not for salespeople (r[140] =−0.008). Finally, constructive coping was significantly correlated with low psychological distress for nurses (r[204] =−0.237, P<0.001), but not for salespeople (r[140] =0.013).

Differences between correlation coefficients

Fisher’s transformed z scores were used to test for differences in the magnitude of the correlation coefficients (see Table 2). Results revealed that the correlation coefficient for the relationship between constructive coping and psychological distress was higher for nurses than for salespeople (z=2.31, P<0.05, Cohen’s q=0.26). There were no significant differences in correlation coefficients for relationships between distancing coping (z=0.27, Cohen’s q=0.03) or reassessing coping (z=1.38, Cohen’s q=0.15) and psychological distress.

Discussion

In the present study, coping strategies for dealing with work-related stress stemming from relationships with patients was assessed in a sample of nurses, and compared with coping strategies and psychological distress in salespeople. Our findings revealed that nurses reported more psychological distress than did salespeople, which is consistent with previous studies that have reported that hospital nurses experience high levels of work-related stress.42 The nature of the interpersonal stressors, however, was different for nurses than for salespeople. For example, nurses often interact with the same patients over a longer period of time than do salespeople, who tend to have shorter encounters with shoppers. In addition, the stressors that arise in nurse–patient relationships are complex (see the “Limitations and future research” subsection).

In addition, in the present study, the relationships between coping strategies and psychological distress were examined. The results indicated that distancing coping was correlated with high psychological distress, which is consistent with findings reported in a sample of college students.33 In addition, reassessing coping was correlated with less psychological distress, which is also consistent with the previous findings on college students.33

Interestingly, constructive coping was correlated with low psychological distress for nurses, but not for salespeople. Moreover, the correlation coefficient for the relationship between constructive coping and psychological distress was higher for nurses than for salespeople. Previous studies with college students also failed to demonstrate a significant relation between constructive coping and psychological dysfunction. Therefore, our findings indicate that, for nurses, constructive coping may be an effective strategy in reducing psychological distress. Constructive coping involves active efforts to improve, maintain, or sustain a relationship without aggravating other individuals involved. For nurses, it may be that relationships with patients are a potential source of stress; however, they are also a source of job satisfaction.43,44 Therefore, effective communication with patients enhances nurses’ job satisfaction; consequently, it may reduce nurses’ stress. Indeed, previous research has shown that nurse–patient communication and interaction are essential aspects of nursing care.4549 The findings of the present study may help nurses better understand the importance of nurse–patient communication.

Limitations and future research

The results of the present study should be interpreted with caution, as this study presents several limitations. First, as the sample included only female Japanese nurses, our findings cannot be generalized to other populations (eg, Western populations). While several studies have indicated that nurses’ perceptions of relationships with patients are sources of stress across cultures,13 other researchers found that coping with interpersonal stressors differs substantially between Asian and Western cultures.50,51 Thus, Japanese nurses’ coping strategies for relationships with patients may differ from those in other populations.

Second, although the primary goal of coping research is to reveal how particular coping strategies affect psychological distress and well-being,24 such causality cannot be inferred from the present findings, as we utilized a cross-sectional design. Future studies should use longitudinal designs and laboratory paradigms in order to test whether nurses’ coping strategies for relationships with patients predict psychological distress or well-being.

Finally, the unique nature of the nurse–patient relationships should be considered when interpreting the present findings. For the general population, interpersonal stressors include stressful episodes between two or more people that involve quarrels, arguments, negative attitudes or behavior, an uncomfortable atmosphere during a conversation or activity, and concern about hurting others’ feelings.31 In addition to these basic interpersonal stressors, nurses’ relationships with patients present stressors such as observing patients’ suffering,12 death and dying,12,52,53 dealing with difficult or severely ill patients,11 and job expectations.54 Patient-related stressors are clearly complex; accordingly, caution is warranted in comparing nurses’ relationship stressors with those of other workers. It could be useful for future nursing research to categorize relationships with patients according to the nature of the stressors.

Conclusion

We found that hospital nurses reported more psychological distress than did salespeople. Further, reassessing coping and constructive coping were effective in reducing psychological dysfunction for nurses, whereas distancing coping was not. It is important for nurses to understand the role of constructive coping in nurse–patient communication and interaction and to learn to adapt their coping strategies as needed.
