Abstract

Background:

Despite the extensive literature on work ability, few studies have looked at variables associated with work ability of nurses working fixed versus rotating shifts.

Objective:

The study aims were to explore variables contributing to work ability and to examine the association of demographic, job satisfaction, and work shift to work ability.

Method:

A cross-sectional design was utilized to assess work ability level and job satisfaction among nurses working 8 or 12 hour rotating or fixed shifts in Jordanian hospitals. The data collection tools were the Work Ability Index and the Mueller/McCloskey Satisfaction Scale. Data were analyzed to determine the extent to which job satisfaction, shift work, and demographic variables were associated with work ability.

Results:

Work ability level was “moderate”, while job satisfaction level was “moderately dissatisfied”. A positive significant relationship was found between work ability and job satisfaction (r = 0.347, n = 349, p < 0.000). This relationship was higher for fixed-shift workers (r =.507) compared to rotating-shift workers (r = .299). Standard linear multiple regression analysis indicated that job satisfaction level predicted work ability level (β =.347, p = .000).

Conclusion:

The study confirmed that promoting job satisfaction leads to higher work ability, and thus, enhances the quality of care provided. The finding that job satisfaction is predictive of work ability has implications for training intervention.

Keywords: Work ability, Job satisfaction, Shift work, Nurses, Jordan, Work Ability Index, Mueller/McCloskey Satisfaction Scale.

1. INTRODUCTION

Worldwide, nurses are the largest workforce in the health care system and are in need of good physical and mental health abilities to perform their job effectively [1Ilmarinen J, Tuomi K. In: Ilmarinen J, Lehtinen S. Past, Present and Future of Work Ability. People and Work. Helskinki: Finnish Institute of Occupational Health 2004;1-25. ISBN 951- 802-581-9, 2Ilmarinen J. Work ability--a comprehensive concept for occupational health research and prevention. Scand J Work Environ Health 2009; 35(1): 1-5.
[http://dx.doi.org/10.5271/sjweh.1304] [PMID: 19277432]
]. These physical and mental abilities are the main components of the concept of work ability [3van den Berg TI, Elders LA, de Zwart BC, Burdorf A. The effects of work-related and individual factors on the Work Ability Index: a systematic review. Occup Environ Med 2009; 66(4): 211-20.
[http://dx.doi.org/10.1136/oem.2008.039883] [PMID: 19017690]
]. Work ability affects a person’s ability to deal with working life, work demands, and job performance. Work ability has been reported in literature for various occupations [2Ilmarinen J. Work ability--a comprehensive concept for occupational health research and prevention. Scand J Work Environ Health 2009; 35(1): 1-5.
[http://dx.doi.org/10.5271/sjweh.1304] [PMID: 19277432]
], however; the concept has been little explored in relation to nurses working in fixed and rotational shifts.

The concept of work ability was developed in 1980 by the Finnish Institution of Occupation Health (FIOH). Work ability refers to how well the workers are able to perform their work [4Tuomi K, Ilmarinen J, Jahkola A, Katajarinne L, Tulkki A. Work Ability Index 1998.]. Furthermore, the FIOH developed the Work Ability Index (WAI) to measure perceptions of workers regarding their physical, mental, and social health and their ability to cope with job demands [4Tuomi K, Ilmarinen J, Jahkola A, Katajarinne L, Tulkki A. Work Ability Index 1998.]. Since then, the WAI has been translated into 21 languages and used in studies concerning work ability levels among workers of various occupational backgrounds [1Ilmarinen J, Tuomi K. In: Ilmarinen J, Lehtinen S. Past, Present and Future of Work Ability. People and Work. Helskinki: Finnish Institute of Occupational Health 2004;1-25. ISBN 951- 802-581-9].

Work ability is an essential concept to assess and promote among nurses working in a hospital environment. Promoting work ability is likely to improve nurses’ work effectiveness and enhance job satisfaction, which, in turn, improves overall health care quality [5Hasselhorn H, Tackenberg P, Muller B. In: Hasselhorn H, Tackenberg P, Muller B, Ed. Working Conditions and Intention to Leave Profession Among Nursing Staff in Europe. Stockholm: Nurses Early Exit Study 2003: 115–124.]. Conversely, low work ability leads to negative impact on work effectiveness and job satisfaction. The results of a study of 4306 nurses in 10 public and private hospitals in Europe were that low WAI scores were associated with work dissatisfaction, work conditions, lack of time for sports or leisure time, and low social support from colleagues [6Estryn-Béhar M, Van der Heijden BI. Effects of extended work shifts on employee fatigue, health, satisfaction, work/family balance, and patient safety. Work 2012; 41(Suppl. 1): 4283-90.
[PMID: 22317378]
]. Further, the results of a systematic review noted that factors associated with low WAI scores included lack of relaxation time, poor musculoskeletal ability, older age, obesity, lack of autonomy, elevated mental work demands, poor work environment, and elevated physical effort load [3van den Berg TI, Elders LA, de Zwart BC, Burdorf A. The effects of work-related and individual factors on the Work Ability Index: a systematic review. Occup Environ Med 2009; 66(4): 211-20.
[http://dx.doi.org/10.1136/oem.2008.039883] [PMID: 19017690]
]. Although the review reported results for healthcare workers, factors such as job satisfaction and shift work demands were not studied.

Nurses are among the many healthcare professionals affected by the requirement to work outside of normal daytime hours, as in working alternate shifts [7Blachowicz E, Letizia M. The challenges of shift work. Medsurg Nurs 2006; 15(5): 274-80.
[PMID: 17128897]
]. This may lead to long working hours (12 vs. 8 hours) and non-ergonomic planning of work schedules (e.g. lack of rest time between shifts and working consecutive night shifts or weekends.). Hence, difficulties in shift-work-related problems, both for the nurses and for those supervising them, may increase the current global nursing shortage [8Camerino D, Conway PM, Sartori S, et al. Factors affecting work ability in day and shift-working nurses. Chronobiol Int 2008; 25(2): 425-42.
[http://dx.doi.org/10.1080/07420520802118236] [PMID: 18484372]
].

Shift work is a known cause of disturbances in the health and well-being of nurses [9West S, Boughton M, Byrnes M. Juggling multiple temporalities: the shift work story of mid-life nurses. J Nurs Manag 2009; 17(1): 110-9.
[http://dx.doi.org/10.1111/j.1365-2834.2008.00920.x] [PMID: 19166529]
]. However, nursing services must be available on a 24-hour basis, making shift work a necessity. The effect of shift work on nurses’ lifestyle, their occupational health issues, and the demands of staffing are documented [8Camerino D, Conway PM, Sartori S, et al. Factors affecting work ability in day and shift-working nurses. Chronobiol Int 2008; 25(2): 425-42.
[http://dx.doi.org/10.1080/07420520802118236] [PMID: 18484372]
]. Also, adverse effects have been noted on workers’ physiological, psychological, and health related problems due to an impairment of biorhythms, although adverse effects vary according to type of shift worked, as in rotational versus fixed shifts [10Saberi HR, Moravveji AR. Gastrointestinal complaints in shift-working and day-working nurses in Iran. J Circadian Rhythms 2010; 8: 9-12.
[http://dx.doi.org/10.1186/1740-3391-8-9] [PMID: 20929565]
].

It was reported that staff working rotational shifts experienced poor work ability, which caused high distress among working staff [11Elovainio M, Kuusio H, Aalto AM, Sinervo T, Heponiemi T. Insecurity and shiftwork as characteristics of negative work environment: psychosocial and behavioural mediators. J Adv Nurs 2010; 66(5): 1080-91.
[http://dx.doi.org/10.1111/j.1365-2648.2010.05265.x] [PMID: 20337789]
, 12Silva1 A, Marqueze1 E, Rotenberg L, Fischer F, Moreno C. Shift workers in electrical systems control rooms: Job satisfaction and work ability. Sleep Sci 2012; 5(2): 49-55.]. In another study, nurses who worked longer shifts (as in 12 hour vs. 8 hour shifts) were susceptible to burnout and made frequent errors at work [11Elovainio M, Kuusio H, Aalto AM, Sinervo T, Heponiemi T. Insecurity and shiftwork as characteristics of negative work environment: psychosocial and behavioural mediators. J Adv Nurs 2010; 66(5): 1080-91.
[http://dx.doi.org/10.1111/j.1365-2648.2010.05265.x] [PMID: 20337789]
]. Also, the authors reported that nurses with low WAI scores reported lower job satisfaction [11Elovainio M, Kuusio H, Aalto AM, Sinervo T, Heponiemi T. Insecurity and shiftwork as characteristics of negative work environment: psychosocial and behavioural mediators. J Adv Nurs 2010; 66(5): 1080-91.
[http://dx.doi.org/10.1111/j.1365-2648.2010.05265.x] [PMID: 20337789]
]. Hence, identifying factors that could influence work ability, such as job satisfaction and type of shift worked, is crucial to maintain nursing efficiency and to promote and achieve health care goals.

In Jordan, there is little literature concerning the effect of job satisfaction of nurses working standard shifts (fixed shift) or non-shifts (rotating shift) on work ability. Although studies conducted in Jordan have investigated job satisfaction [13Hamaideh SH. Burnout, social support, and job satisfaction among Jordanian mental health nurses. Issues Ment Health Nurs 2011; 32(4): 234-42.
[http://dx.doi.org/10.3109/01612840.2010.546494] [PMID: 21355758]
, 14Raddaha A, Ab A, Jafar A, et al. Jordanian nurses’ job satisfaction and intention to quit. Leadersh Health Serv 2012; 25(3): 216-31.
[http://dx.doi.org/10.1108/17511871211247651]
], no study was found that specifically addressed work ability and its association with job satisfaction among nurses working fixed or rotating shifts. The current study was designed to fill this gap and provide baseline information regarding work ability among nurses working varying shifts in Jordanian teaching hospitals. For purposes of this study, shift work refers to either rotating or fixed shift work. In the hospitals from which the sample was drawn, nurses worked either 8 or 12 hour rotating day or night shifts, or they worked 8 or 12 hour morning, evening, or night fixed shifts.

1.1. Aims of the Study

The primary aim of this study was to examine level of work ability among hospital nurses in Jordan. The secondary study aims were as follows:

  1. Determine level of work ability and job satisfaction between nurses working rotating or fixed shifts.
  2. Identify associations between work ability and job satisfaction for nurses working four types of shifts (8 hour rotating, 12 hour rotating, 8 hour fixed, 12 hour fixed).
  3. Determine whether demographic factors are associated with or predict work ability or job satisfaction.

2. MATERIALS AND METHODS

2.1. Research Design and Sample

A cross-sectional design was used to assess levels of work ability and job satisfaction for nurses working in two teaching hospitals in Jordan. The target population consisted of nurses working all shifts across all departments of the teaching hospitals who were available at the time of data collection. The inclusion criteria were registered nurses who worked rotational or fixed shifts with at least one year of work experience. Nurse Managers or supervisors were not included due to differing work hours and roles. To gain an estimate for sample size, G* power [15Faul F, Erdfelder E, Lang AG, Buchner A. G*Power 3: a flexible statistical power analysis program for the social, behavioral, and biomedical sciences. Behav Res Methods 2007; 39(2): 175-91.
[http://dx.doi.org/10.3758/BF03193146] [PMID: 17695343]
] for a medium effect size at an 0.05 alpha level at 80% power resulted in 350, to which 50 was added to account for attrition, bringing the total estimated account to 400. However, 390 data collection sets were returned and due to incomplete data, 41 were rejected. This resulted in a final sample size of 349, and time restrictions did not allow for followup of the 41 respondents to increase the sample size. The response rates from the two hospitals were as follows: 40% (n = 160) from one hospital and 47.9% (n = 190, although 1was withdraw) from the other.

2.2. Measures

Respondents completed a data sheet for identifying personal demographics and type of shift worked. Respondents were asked to state their age, gender, marital status, educational level, years of work experience, family status, type of the work setting (intensive care, medical-surgical, obstetric, pediatric, or emergency) and type of shift work. In this study, the shifts worked were fixed 8 hour shifts (morning, evening, or night), 12 hour shifts (day or night), rotating 8 hour shifts (morning, evening or night) or rotating 12 hour shifts (day or night).

The data collection instruments used in this study were Arabic versions of the Work Ability Index (WAI) and the Mueller/McCloskey Satisfaction Scale (MMSS). Agreements were obtained to translate the instruments into Arabic. Arabic versions of both instruments were developed using a translation and back translation technique. Performed at a Certified Language Center, the English versions were translated into Arabic and then back translated into English by a different language expert. A panel of professional bilingual and bicultural nursing professionals assessed the Arabic versions for content validity. A pilot test of the Arabic versions (n=40) resulted in Cronbach’s alpha coefficients of 0.85 for the WAI and 0.95 for the MMSS.

The WAI, a widely used index of work ability, measures respondents’ perceptions regarding their physical, mental, and social health and their ability to cope with job demands [4Tuomi K, Ilmarinen J, Jahkola A, Katajarinne L, Tulkki A. Work Ability Index 1998.]. The questions cover current work ability, ability to work within job demands, the number of illnesses/limitations, impairments affecting work ability, the amount of sick leave taken within the last year, and an estimate of work ability within 2 years’ time. As each answer has a different score, the total work ability score is calculated by adding scores across the dimensions. The resulting score range is 7 (low work ability) to 49 (high). The authors reported a Cronbach’s alpha coefficient of 0.83 and a content validity index of 0.79 [4Tuomi K, Ilmarinen J, Jahkola A, Katajarinne L, Tulkki A. Work Ability Index 1998.].

The MMSS, originally developed for hospital nurses, measures job satisfaction. The scale contains 31 items, and each item is scored on a 5-point Likert scale, where, 1 corresponds to very dissatisfied, 2 to moderately dissatisfied, 3 to neither satisfied nor dissatisfied, 4 to moderately satisfied, and 5 to very satisfied. The MMSS evaluates job satisfaction in relation to satisfaction with extrinsic rewards, scheduling, family/work balance, co-workers, interaction, professional opportunities, praise/recognition, and control/responsibility. The alpha coefficient for the scale is 0.89 and the content validity index is 0.83 [16Mueller CW, McCloskey JC. Nurses’ job satisfaction: a proposed measure. Nurs Res 1990; 39(2): 113-7.
[http://dx.doi.org/10.1097/00006199-199003000-00014] [PMID: 2315065]
].

2.3. Data Collection Procedure

Approval to conduct the study was obtained from the Institution Review Board (IRB) of the principle investigator’s academic institution and administrators of the target hospitals. Times of data collection covered all shift options to ensure nurses had an equal chance to participate in the study. To recruit nurse respondents, all nurses available at time of data collection were given a cover letter that explained the purpose of study and ensured them that participation or non-participation would not be reported to their supervisors. The nurses were informed that participation was voluntary, and respondents’ anonymity and information confidentiality were ensured. Nurses interested in participating signed a consent form. Nurses were given the study questionnaires (demographic form, WAI, and MMSS) in an enclosed envelope. They completed the instruments on site and handed them back to the researchers.

2.4. Data Analysis

The data were analyzed using the Statistical Package for Social Sciences (SPSS; IBM Statistics for Macintosh, Version 22.0). Descriptive statistics permitted describing sample characteristics. Pearson correlation coefficient tests were used to identify the relationship between work ability and job satisfaction. Independent sample t-tests were used to compare mean differences in work ability and job satisfaction for rotational versus fixed shift workers. Multiple regression tests were used to identify possible predictors of work ability. Although the sample size of 349 was short of the 400 (350 + 50 for attrition) estimated to achieve power, results can be considered indicative, yet must be treated with caution.

3. RESULTS

3.1. Sample Characteristics

The mean age of participants was 29 years, with an average of 6 years of work experience, which was deemed adequate to provide work experiences for assessing work ability and job satisfaction. Although female nurses outnumbered male nurses (206 to 143), the difference was 63 less males than females. All but two nurses (diploma) had baccalaureate or higher degrees (n=347, 99.4%). More than half of nurses (n=221, 63.4%) worked in 8 hour rotating shifts (morning, evening or night), with the smallest frequency of the sample working 12 hour fixed shifts (n = 28, 8.0%). As nurses working in all shifts within the hospital at the time of data collection were included in the sample, their work settings were distributed across hospital departments. All but two of the nurses worked as staff nurses. More than half of the participants (n= 204, 58.3%) lived in a city other than that of the hospital’s location. Most of participants reported that transportation was not provided by their hospitals (n=263, 75.1%). Table 1 shows sample characteristics according to demographic variables.

Table 1
Descriptive characteristics of nurse participants (n = 349).


3.2. Work Ability and Job Satisfaction

The total mean WAI score among hospital nurses was moderate (µ = 29.3, SD = 6.8). For total WAI scores, the classification by range of scores is as follows: Low, 7-27; Moderate, 28-33; Good, 34-43; and Very good, 44-49. The highest scoring dimension subscale was “estimate of work ability as compared to job demand” (µ = 5.84, SD =1.89), where the score range was 2-10. The lowest scoring dimension subscale was number of current diseases/limiting conditions (µ = 2.61, SD = 2.25), where the score range was 1-7.

The total mean score for MMSS was low (µ = 34.6, SD = 8.50), equivalent to moderately dissatisfied. For total MMSS scores, the range is 31 (very dissatisfied) to 155 (very satisfied). The dimension subscale with the highest mean score was “satisfaction with external rewards” (µ = 1.8, SD = .82), where the range was 1-5. The subscale dimension with the lowest mean score was “satisfaction with work/family balance” (µ = .74, SD = .88), where the range was 0-4.

3.3. Work Ability among Shift Workers and Non-Shift Workers

For purpose of this study, shift working was defined as the type of shift the nurse worked, which for participating nurses was fixed shifts (8 hours or 12 hours) corresponding to “shift worker” designation, or was rotating (8 hours or 12 hours), corresponding to “non-shift worker” designation. An independent sample t-test showed no significant difference (t = -1.37, p > 0.05) between mean WAI scores for shift workers (M = 29.5, SD = 6.5) and non-shift workers (M = 28.3, SD = 8). However, a one way ANOVA showed a significant difference in the levels of work ability between the 4 types of fixed and rotating shifts (F = 11.17, p < .01). A post hoc Scheffe test was used to determine the difference between these shifts. The test showed a mean difference in work ability between fixed 8 hour shifts and 12 hour rotating shifts, but not a mean difference between fixed 12 hour shifts and rotating 12 hour shifts, as shown in Table 2.

Table 2
Scheffe test assessment of differences in work ability between types of shifts worked.


3.4. Relationships among Study Variables

A correlational matrix was constructed using Pearson’s product- moment correlation to assess to what extent demographic variables and work shift correlated with work ability (WAI scores) and job satisfaction (MMSS scores). The matrix used Pearson correlation for continuous variables and point biserial correlation for dichotomous variables. The continuous independent variable that significantly correlated to work ability was “work experience in years” (r =-.311, p <.001). Categorical variables that significantly correlated to work ability were “being married” (r =- .254, p < .001) and “transportation unavailable “(r= .212, p <.001). The correlational matrix is shown in Table 3.

Table 3
Pearson product-moment correlation coefficients of demographic variables with WAI total score, MMSS total score, and work shift.


To identify the relationship between work ability and job satisfaction; the results revealed a positive, significant relationship between WAI and MMSS mean scores (r =.347, n = 349, p < 0.000). The higher level of work ability correlated with a higher level of job satisfaction. Moreover, the results revealed a positive, significant relationship for rotating shift workers (r = .299, n=282, p < .000), albeit the correlation between rotating shifts and WAI scores was not strong. A stronger relationship was noted for fixed-shift workers (r =.507, n=67, p < .000).

3.5. Work Ability Predictors

Standard linear multiple regression analysis was used to identify significant predictors of nurses’ work ability. The data were assessed for outliers, multicollinearity, normality, linearity, and independence of residuals. In relation to WAI scores, where the variables showing significance (demographic, work shift and job satisfaction) were used in the regression analysis, results indicated that 44.4% of work ability variance was explained by the independent variables (R2 =.444, adjusted R2=.395), and the model was significant (F = 9.08, p < .000). Of the demographic variables that were significantly correlated with work ability, only “years of work experience” and “marital status” did not significantly predict work ability (t= 0.3 and t=.09 respectively). In addition, a significant relationship was found between job satisfaction and work ability when accounting for demographic variables (B = .1, t = 5.2, p < .01). The linear multiple regression analysis results in relation to WAI scores are shown in Table 4.

Table 4
Standard linear multiple regression analysis of demographic, work shift, and WAI variables.


In relation to MMSS scores, or job satisfaction, the regression analysis showed that work ability significantly influenced job satisfaction (B = .7, t = 5.2, p < .000). The regression model showed that the factors significantly predicted job satisfaction (F = 12.2, p < .01) and accounted for 20% of the variability of the job satisfaction scores (R2 = 0.201). When nurses reported high job satisfaction level, they experienced high work ability level. The linear multiple regression analysis results in relation to MMSS scores are shown in Table 5.

4. DISCUSSION

The study was designed to add knowledge of factors contributing to optimizing productivity in the context of work ability of rotating and fixed shift nurses in Jordanian public hospitals and the relationship of job satisfaction to work ability. Results of the current study indicated that nurse respondents self-reported a moderate work ability level (WAI total score mean of 29.3). This result was lower than found in a study of Taiwanese nurses, where the reported a WAI mean score was 36.4 (in the Good range), which the authors considered to be an “average” work level [17Chiu MC, Wang MJ, Lu CW, Pan SM, Kumashiro M, Ilmarinen J. Evaluating work ability and quality of life for clinical nurses in Taiwan. Nurs Outlook 2007; 55(6): 318-26.
[http://dx.doi.org/10.1016/j.outlook.2007.07.002] [PMID: 18061017]
]. However, authors at an academic medical center in the Netherlands [18Ruitenburg MM, Frings-Dresen MH, Sluiter JK. The prevalence of common mental disorders among hospital physicians and their association with self-reported work ability: a cross-sectional study. BMC Health Serv Res 2012; 12: 292-8.
[http://dx.doi.org/10.1186/1472-6963-12-292] [PMID: 22938170]
] reported a considerably lower mean of 8 (in the Low range). Given this diversity, additional studies are needed to investigate which factors contribute most and least to nurses’ work ability and establish how scores relate to low, moderate, or high levels of work ability.

Job satisfaction is one aspect associated with work ability and needs to be considered as a contributing factor. In the current study, nurses with higher job satisfaction scores (MMSS highest score highest was 93 of 155) also had higher work ability scores (the highest WAI was 46 of 49). Similar results were found in a study of nurses in an emergency unit; that is, when job satisfaction increased, work ability increased [19Santos Y, Porto F, Marques L, Tomaz A, Toledo R, Lucena N. Assessment of work ability of health professionals in the mobile emergency unit. Work 2012; 41(Suppl. 1): 778-82.
[PMID: 22316815]
]. In the current study, results indicated that Jordanian nurses in teaching hospitals were moderately dissatisfied with their job. In other studies of job satisfaction [20Saleh M, Darwado A, Al-Hussami M. Organizational commitment and work satisfaction among Jordanian nurses: A comparative study. Life Sci J 2014; 11(2): 31-6., 21Silva-Costa A, Rotenberg L, Griep RH, Fischer FM. Relationship between sleeping on the night shift and recovery from work among nursing workers - the influence of domestic work. J Adv Nurs 2011; 67(5): 972-81.
[http://dx.doi.org/10.1111/j.1365-2648.2010.05552.x] [PMID: 21214622]
], Jordanian hospital nurses rated their job satisfaction as neutral (“neither satisfied or dissatisfied”). However, one study found that Jordanian mental health workers rated their job satisfaction as moderate [13Hamaideh SH. Burnout, social support, and job satisfaction among Jordanian mental health nurses. Issues Ment Health Nurs 2011; 32(4): 234-42.
[http://dx.doi.org/10.3109/01612840.2010.546494] [PMID: 21355758]
].

Possible causes of less than high job satisfaction may be due strict organizational policies and lack of effective communication between medical doctors and nursing staff, especially in teaching hospitals. In addition, nurses in teaching hospitals face job stressors, such as increased workloads, and having to perform multiple non-nursing roles, such as clerk, educator, family mediator, or student preceptor. In addition, the Syrian crisis is likely influencing job satisfaction because of the increased pressure on hospitals resources to care for refugees.

4.1. Work Ability and Shift Work

In terms of the relationship between shift work and work ability, few studies have examined how one influenced the other. One study reported that nurses who worked fixed night shift had WAI scores that were significantly lower than nurses who worked rotating day or night shifts [22Camerino D, Conway PM, van der Heijden BI, Estryn-Béhar M, Costa G, Hasselhorn HM. Age-dependent relationships between work ability, thinking of quitting the job, and actual leaving among Italian nurses: a longitudinal study. Int J Nurs Stud 2008; 45(11): 1645-59.
[http://dx.doi.org/10.1016/j.ijnurstu.2008.03.002] [PMID: 18456268]
]. Supporting this, another study reported that night shift work was associated with low work ability scores [23Rotenberg L, Griep RH, Fischer FM, Fonseca MdeJ, Landsbergis P, Landsbergis P. Working at night and work ability among nursing personnel: when precarious employment makes the difference. Int Arch Occup Environ Health 2009; 82(7): 877-85.
[http://dx.doi.org/10.1007/s00420-008-0383-4] [PMID: 19009305]
]. Further, a third study reported that there was negative relationship between shift work and work ability for nursing personal [24Safari S, Akbari J, Kazemi M, Mououdi MA, Mahaki B. Personnel’s health surveillance at work: effect of age, body mass index, and shift work on mental workload and work ability index. J Environ Public Health 2013; 2013: 289498.
[http://dx.doi.org/10.1155/2013/289498] [PMID: 23956756]
]. However, in contrast, a fourth study reported no association between shifts’ worked and work ability [25Sorić M, Golubić R, Milosević M, Juras K, Mustajbegović J. Shift work, quality of life and work ability among Croatian hospital nurses. Coll Antropol 2013; 37(2): 379-84.
[PMID: 23940978]
].

Possible contributions to inconsistencies in research findings may be because participants differed in the type of nursing work performed. More so than time or type of shift, differing work settings have differing protocols, work procedures, and socio-cultural expectations.

The current study is the first to investigate work ability level among shift work nurses in Jordan. Additional studies are needed to determine other factors that contribute to and affect work ability among nurses. Focus should be on differences between work ability level for shift workers and non-shift workers, factors that predict work ability level, and the association of job satisfaction for shift workers with work ability. In addition, longitudinal studies are needed to determine how favorable work conditions help to maintain and improve work ability.

CONCLUSION

This study is an early effort to assess work ability level and factors contributing to it among nurses in Jordan. A main finding is that job satisfaction is predictive of work ability. Additionally, the type of work shift, albeit a possible contributor needs definitive study. Although it is beyond the purpose of this study, an implication is that low work ability could have negative outcomes for nurses working in a hospital environment. The potential for negative outcomes deriving from low work ability should be taken into account when planning program interventions to improve nursing efficiency. Therefore, the current study has implications for practice, policymaking, and research. Nurse administrators in cooperation with Nursing Councils should aid in developing workplace policies to enhance work ability and, therefore, job satisfaction, especially for nurses working 12-hour rotating shifts.

STUDY LIMITATIONS

As an initial investigation of associations of work ability for shift working nurses in Jordan, the study served as a one-time study of nurses’ self-reported perceptions. A longitudinal study would produce a more comprehensive overview of existing relationships, especially as self-reporting is itself subjective, and could help in establishing causality. The sample respondents were recruited from teaching hospitals, which may have stricter policies and procedures than other general acute care hospitals. In addition, the sample size, although near to, did not reach the estimated sample size to achieve power.
