Abstract

Background: Stress is an important occupational hazard in numerous occupations. The consequences of stress have been associated with a number of health conditions.

Objectives: The aim of this study was to investigate whether nurses’ perceived levels of stress are associated to presenteeism and absenteeism.

Materials and Methods: In a cross-sectional study, conducted at a public general hospital in Croatia, medical nurses filled the perceived stress scale (PSS-10) and short-form of the World health organization health and work performance questionnaire (WHO HPQ).

Results: Nurses experiencing absenteeism (26, 53%) had a little higher levels of stress (X = 18.85, SD = 7.31) when compared to those without absenteeism (X = 17.52, SD = 6.63), t (144) = 1.037, P = 0.301. Nurses with presenteeism (15.74%) had statistically significantly higher levels of stress (M = 21.42, SD = 5.62), compared to nurses without presenteeism (X = 17.35, SD = 6.84), t(144) = 2.47, P = 0.015. Linear regression (R2 = 0.032, P = 0.036) showed an association between presenteeism and stress (B = 3.952, S.E. = 1.26, β = 0.069). No association was found between absenteeism and stress.

Conclusions: Although there is an association between presenteeism and stress, we cannot draw a causal line from this finding.

1. Background

Workplace demands can be perceived as stressful to an individual. As described by Kahn & Byosiere, job stress relates to physical and behavioral outcomes such as burnout, health complaints, and absenteeism (1). Moreover, these outcomes seem to be interrelated (2, 3). Acute stress response allows individuals to mobilize the energy required to fight or overcome stress (“fight or flight”). The short-term impact of stress does not have to lead to adverse health effects. In fact, short-term stress can have a positive impact. However, the allostatic load theory describes long-term effects of stress as damaging due the wear and tear of the body experiences (4). Stress activates primary stress mediators (cortisol, epinephrine, norepinephrine and dehydroepiandrosterone), which lead to switching from homeostasis in the body to allostasis (Figure 1). The primary stress mediators lead to changes in cardiovascular (catecholamines), metabolic (glucocorticoids), immune (glucocorticoids and catecholamines) systems and brain (glucocorticoids and catecholamines). Consequently, this leads to an increase of waist-hip ratio, blood pressure, cholesterol, glucose and decrease of insulin, immune capacity and glucose tolerance (secondary outcomes) resulting in, cardiovascular disease, severe cognitive decline, diabetes, hypertension and cancer (tertiary outcomes) in the long run (5). With the onset of a disease (acute, episodic or chronic), an employee has an option of taking sick leave (sickness absenteeism) or to come to work despite of the illness (sickness presenteeism). The decision to come to work despite of existing health challenges or to take sick leave is often complex. Even though presenteeism and absenteeism are extreme values on the working scale, similar health, workplace and personal factors affect both of them, but in an opposite manner. As mentioned above, disease is one of the common factors. Workplace factors (perception of the working environment either as a positive or a negative place, daily “must-do tasks”, replacement difficulties and tasks that need to be personally covered upon return, management-employee relations, support from peers, job insecurity and culture) and personal reasons (financial reasons, attitudes toward own health, work-life balance and family) often influence the decision of whether to come to work or not (6-13). Moreover, absenteeism and presenteeism are often inter-related. Employees whose health problems have not led to absenteeism often show presenteeism. On the other hand, if the employee returns to work while still sick or recovering, the sickness absenteeism can be replaced with sickness presenteeism. Even more so, sickness presenteeism has significant predictive value for future absenteeism (7, 14-16).

Absenteeism is defined as any absence from work. Sickness absenteeism is usually registered as sick leave, which sometimes makes it hard to distinguish from just not coming to work (7, 17). In Croatia, healthcare and social care sector have the highest sick leave rate. During the year 2013 this rate was 3.11% (18, 19). The frequency of absenteeism can suggest employees’ gradual withdrawal behavior, which can result in turnover. Duration of absences is indicative of poor health (13, 20). Eriksson et al. found that burnout was associated with long-term sickness absence. They described that events prior to sickness absence can be understood as a process of emotional deprivation, which was described in terms of a flight of stairs with eight steps, which were named "The Burnout Stairs." The course of events preceding sickness absence is a process of emotional deprivation where the individual is gradually emptied of the life-giving emotional energy revealed in joy, commitment and empathy (21). Another model, described by Bakker et al. showed that burnout mediated the effects of job demands on absence duration (13, 20).

In general, presenteeism is defined as being present at work, but not being able to work in the usual manner (14, 22-24). Employees often work with lower performance (not meeting deadlines, difficulty in concentrating, not being able to think clearly, making mistakes and not being able to carry out the physical requirements of a job), which results in lost productivity (25, 26). Presenteeism is even more difficult to measure since there are almost no objective measures. Presenteeism is usually investigated using questionnaires. Therefore, reported presenteeism rates are variable. A Dutch study reported that 70% of the randomly selected participants reported coming to work sick at least one time during the last year (27). Sickness presenteeism due to acute illness (cold, flu, allergy, etc.) is sometimes more favorable to the employees because they have a choice of whether or not to attend work (8). When it comes to sickness presenteeism due to chronic condition (arthritis, back pain, mental health problems, etc.) employees may need to work despite the impairment (8, 28). This type of presenteeism has become a challenging problem in developed countries due to ageing workforce and an increasing number of people with chronic health conditions (29).

1.1. Nurses

This study was specifically targeted at nurses, as one of the largest groups of healthcare professionals that play a crucial role in proper healthcare delivery (30). Nurses are more likely to come to work when sick than other occupations (7, 31, 32). Poor health can affect their performance, which can consequently affect the quality of health care (28). Absenteeism is associated with missed nursing care (33). Nurses and teachers have the highest occupational rates of this type of presenteeism (8). Literature review suggested that demands such as organization of work, financial issues, public criticism, hazards at workplace, interpersonal conflicts, shift-work, professional and intellectual demands, and prolonged fatigue are perceived by nurses as stressful (34, 35).

1.2. Healthcare and Nursing in Croatia

Croatia has a population of 4 284 899. There are 67 hospitals. There are five clinical teaching hospitals, three clinical hospitals, four clinics, 22 general hospitals, and 33 special hospitals. Clinical teaching hospitals and clinical hospitals are state owned. All other hospitals are country owned (36).

Nurses in Croatia are a very important part of Croatian health care. This professional category accounts for 30 000 trained nurses, out of which over 7000 have a college degree. Their activities, education standards, performance requirements, duties and performance quality assessment criteria are stated under the Nursing Act (2003) (37). Most of the nurses work in health care institutions, while a smaller number work in other institutions providing health and social services. Registered nurses can work as a part of a health care team (in primary care settings or in a hospital). Registered nurses having a higher or high education can work as a nursing team leader (38).

2. Objectives

It was our aim to investigate whether nurses’ perceived levels of stress are associated with presenteeism and absenteeism. Our hypotheses are:

1. Stress is associated to absenteeism

2. Stress is associated to presenteeism

3. Materials and Methods

3.1. Participants

This was a cross-sectional study, which included medical nurses. The study was conducted at a Public General Hospital in Croatia. The eligibility criteria were set using a convenience sample, which involved the employees’ willingness and consent to take part, as well as the geographical proximity to the researchers. The research was anonymous and free willing. A convenience sample of Registered Nurses was recruited. Data were collected during April and May 2012.

3.2. Data Collection

Weekly educational nurses’ meeting was used to distribute the questionnaire. Questionnaires were distributed in unmarked envelopes along with a consent form by the main investigator. After being filled, the questionnaires and the consent forms were returned in separated sealed and unmarked envelopes. Each respondent returned their envelope to a box, which was found in the nurses’ room at each department. Head nurses of the departments collected the boxes and the returned them to the main investigator.

The survey made use of two questionnaires: perceived stress scale (PSS-10) and short -form of the world health organization health and work performance questionnaire (WHO HPQ).

3.2.1. Perceived Stress Scale

Perceived Stress Scale (PSS) was designed to measure the stress degree of situations in one’s life appraised as stressful (39). The PSS consists of ten questions, which ask the respondent to indicate how often they felt or thought in a certain way in the last month (Appendix 1 in supplementary file). The answers were scaled from 0 to 4: never was scored 0, almost never 1, sometimes 2, fairly often 3, and very often 4. The PSS-10 scores are obtained by reversing the scores on the four positive items, e.g., 0 = 4, 1 = 3, 2 = 2, etc. and then summing across all 10 items. Items 4, 5, 7 and 8 are the positively stated items.

3.2.2. World Health Organization Health and Work Performance Questionnaire

World health organization hpq questionnaire, first developed by Kessler et al. in 2002, is a self-report instrument designed to estimate the workplace costs of health problems in terms of reduced job performance, sickness absence and work-related accidents/injuries (40). The tool has been shown to have good validity and internal consistency (40). The WHO HPQ short-form consists of 11 questions/statements in which the respondents are asked to describe their work experiences during the seven days of the past four weeks (Appendix 2 in supplementary file). There are two ways of measuring and scoring absenteeism. One relies on the respondent estimating how many hours he/she worked over a four-week period. The other asks the respondent to estimate how many hours he/she worked in the past seven days. The authors of the questionnaire recommend using the four-week estimates when available, as they will tend to smooth out any up or down spikes that might have occurred in a particular week (e.g. a respondent missing several hours of work because of a doctor’s appointment). In this research, we used the absolute absenteeism four-week estimate, which is also used in similar research by the authors of the WHO HPQ (41). In this research, we will name the absolute absenteeism 4-Week Estimate just Absenteeism. Presenteeism is conceptualized as a measure of actual performance in relation to possible performance. Unlike absenteeism, a higher score indicates a lower amount of lost performance (42). For the purposes of this research, absolute presenteeism will be referred to as presenteeism.

3.3. Ethical Considerations

Since this research was conducted while the first investigator attended postgraduate studies, an approval was obtained from the School’s ethical board. An approval was obtained from the hospital board of ethics. After approval from the hospital was obtained, approval from hospital’s manager was also obtained. Additionally, participants also provided consents.

3.4. Data Analysis

All questionnaires were collected and entered to an electronic database and completeness of the data was checked. Questionnaires with missing data were excluded.

For all analyses, statistical significance was set at P value of < 0.05. Normality of the data distribution was tested using Kolmogorov-Smirnov Normality Test. Descriptive analysis was used to analyze the participants’ age, stress, presenteeism and absenteeism. T-test was used for analysis to compare means of stress. Linear regressions were used to assess the possible association between presenteeism and stress, and between absenteeism and stress. Analysis was performed using SAS version 9.1.3.

3.5. Validity and Reliability

Both questionnaires showed adequate internal consistency. The PSS had a Cronbach’s α of over 0.80 for three samples (0.84, 0.85 and 0.86, respectively) (39). The HPQ validation studies showed good concordance between measures of self-reported absenteeism and payroll records over a 30-day recall period, with Pearson correlations in the range 0.66 to 0.79 and evidence of some downward bias in mean self-reported absenteeism levels. The HPQ validation studies documented fair to good concordance between measures of self-reported presenteeism and independent measures of work performance based on either supervisor or peer ratings (40, 41, 43). The WHO HPQ questions were translated to Croatian by one translator and then translated back to English by an independent translator, who was blinded to the original questionnaires. Preliminary research was then performed to estimate questionnaires’ validation and standardization. The results are presented in separate research papers, one of which was recently published (44).

4. Results

4.1. Demographic Data

A total of 194 questionnaires were distributed to all of the nurses, who worked at the hospital at the time. The participating nurses operated in non-surgical, surgical, pediatric, obstetrics, psychiatry departments and intensive care unit (ICU). One hundred and forty-seven questionnaires were returned yielding response rate of 75.77%. Most of participating nursing staff (who wanted to declare their gender) were female (87.36%, N = 87). Most of the respondents worked at non-surgical departments (55/147, 37.41%), while 29.25% (43/147) worked at the surgical department, 12.24% (18/147) worked at the obstetric department, 10.88% at the ICU (16/147), 7.48% (11/147) at Pediatric department, and 2.72% (4/147) at the psychiatric department. Kolmogorov-Smirnov test reported a non-normal age distribution, D (82) = 0.165, P < 0.001. The median for age distribution was 45 (SE = 1.03), with the minimal value of 22, and the maximal value of 59.

4.2. Results of Perceived Stress Scale

Kolmogorov-Smirnov test reported the PSS distribution to be normal, D (82) = 0.058, P = 0.200. The mean score was X = 17.09, SD = 6.64.

4.3. Absenteeism

Absenteeism is scored in terms of hours lost per month; a higher score indicates a higher amount of absenteeism. The measure of absolute absenteeism is expressed in raw hours, with a negative lower bound (if the person works more than expected) and an upper bound equal to the number of hours the respondent is expected to work (42). Kolmogorov-Smirnov test reported a non-normal absenteeism score, D (146) = 0.134, P < 0.001. The median for absenteeism distribution was 32 hours (SD = 68.8), with minimal value of -184 and the maximal value of 224. This means that an average nurse in our sample did not spend almost a week (32 hours) in the past four weeks. We wanted to further examine nurses with absenteeism, so we used 75th percentile to dichotomize the sample in two subgroups. The nurses in the 75th percentile (64 hours) were place in the Absenteeism group. There were 39 (26.53%) nurses with absenteeism and 108 without absenteeism. Nurses in the Absenteeism group had a little higher levels of stress (X = 18.85, SD = 7.31) when compared to those without absenteeism (X = 17.52, SD = 6.63), but the difference was not statistically significant, t (144) = 1.037, P = 0.301.

4.4. Presenteeism

Presenteeism had a lower bound of 0 (total lack of performance during time on the job) and an upper bound of 100 (no lack of performance during time on the job). Kolmogorov-Smirnov test reported a non-normal absenteeism score, D (146) = 0.2, P < 0,001. The median for presenteeism distribution was 90 hours (SD = 20.145), with minimal value of 0 and maximal value of 100. Lower quartile (25 hours) was used to determine which nurses experienced presenteeism. A total of 20 nurses (15.74%) experienced presenteeism, while 127 did not. Nurses with presenteeism had significantly higher levels of stress (X = 21.42, SD = 5.62), compared to nurses, who had not experienced presenteeism (X = 17.35, SD = 6.84), t (144) = 2.47, P = 0.015. There were seven nurses, who had experienced both presenteeism and absenteeism.

Linear regression (R2 = 0.032, P = 0.036) showed an association between presenteeism and stress (B = 3.952, S.E. = 1.26, β = 0.069). No association was found between absenteeism and stress (B = 1.057, S.E. = 1.657, β = 0.196).

5. Discussion

The mean PSS (D (82) = 0.058), score was similar to the PSS score (18.32) previously described for females of Croatia, in a population study (CroHort) (44). Most of our respondents were females in their forties. According to previous studies, females have consistently higher PSS scores. This was attributed to negatively scored items in the PSS; females often score higher and subjectively experience more stress than males and show a greater worry-disposition (39, 44-49). However, nurses, who had experienced presenteeism, had a statistically significant higher PSS score (21.42). Our findings were similar to that of Musich et al. who found statistically significant higher rates of presenteeism among individuals with high stress (24). A study by MacGregor et al. showed that stressful life events are related to sickness presenteeism in the same extent as they are to sickness absenteeism (14). This was not the case in our sample. Nurses, who had experienced absenteeism, had somewhat higher levels of stress, but the difference was not statistically significant. However, we found it very interesting that in our sample the nurses did not work one week in the four-week frame that was examined. Another interesting finding was that although only 15.74% nurses reported they had experienced presenteeism, they had statistically significantly higher levels of stress. Research also suggests that sickness presenteeism is a marker of a lifestyle in which symptoms are ignored and medical care is not sought when needed (50, 51). These findings suggested that presenteeism could be seen as a risk-taking organizational behavior and shows substantial longitudinal relationship with job demand and burnout. Job demand caused higher presenteeism, while depersonalization was an outcome of presenteeism over time. Exhaustion and presenteeism were found to be reciprocal, suggesting that when employees experience exhaustion, they mobilize compensation strategies, which ultimately increase their exhaustion (3).

We were unable to compare our findings with similar papers in which WHO HPQ was used. The reason is that we were able to access only five papers (40-43, 52, 53). Another reason is that the authors had not used the same questions from the questionnaire and that the results had not been presented in the same manner in all of the papers. We believe that this is something that should be improved for future use. One of the reasons we used this tool was that it measures both presenteeism and absenteeism. This is very important, because there are only a small number of published papers on presenteeism, and even smaller number on presenteeism in nursing. Even more so, a number of papers showed that absenteeism and presenteeism are inter-related (7, 11, 14-16). However, we encourage the authors of the questionnaire as well as all of the authors using it, to make a consensus on reporting the data. We acknowledge that the convenient sample and relatively small number of participating nurses may have biased the results and that the results might not be generalizable. However, we feel that this convenience sample gives us an insight into an average hospital in Croatia. Another limitation might be that, even though the research was anonymous; the respondents did not feel comfortable to truthfully answer all of the questions. We were not given access to use the actual sick-leave data to compare to absenteeism data. However, HPQ validation studies show good concordance between measures of self-reported absenteeism and payroll records over a 30-day recall period, with Pearson correlations in the range of 0.66 to 0.79 and evidence of some downward bias in mean self-reported absenteeism levels (40, 41, 43).

We cannot draw generalized conclusions form our results. Our results simply depict a situation we found in our population at a certain moment in time. We found the results interesting and we believe that these results are important findings for occupational health professionals as well as hospital managers, heads of departments and nurses. Future research should aim at a larger group of nurses as well as including other healthcare professionals.

5.1. Conclusion

Even though we cannot draw a causal line from this finding, we found the association between presenteeism and stress interesting. We hope that future research will aim at studying larger groups of healthcare professionals with continuous work for designing even more comprehensive absenteeism and presenteeism tools.
