Introduction
Occupational activities occur at the most wakeful times of most people. Putting high emphasis on the work time and energy will culminate in many physical, social, and psychological reflections on employees (1, 2). In addition, work can be a source of stress and many concomitant negative outcomes in individuals and organizations (3, 4). Job stress is one of the factors affecting employee productivity in every organization. Based on the job demand-resources model (JD-R model), occupational stress is defined as an aspect of a job that involves physical and psychological costs to employees (5).
Job stress is one of the major factors that can exert a negative impact on employee performance, increase the probability of physical and psychological damage to employees, and reduce organizational productivity (6, 7). In this regard, job stress and resiliency as well as their relationship have been the subjects of many studies. Research shows that resiliency is considered an effective coping style in dealing with job stress (8). Resiliency refers to the capacity of individuals to stay healthy and firm in unfavorable work conditions (9). Emotion regulation can also be considered a coping mechanism in managing stress in high-risk work environments (10). Emotion regulation is defined as the conscious or unconscious process of initiating, maintaining, or modifying pleasant or unpleasant emotions (11).
Nevertheless, it is expected that mindfulness trainings be effective in reducing job stress, while improving resiliency and emotional regulation. Mindfulness is defined as the state of consciousness in which a person has a conscious, purposeful, contemporary, and non-judgmental attitude towards his internal and external circumstances (12). Clinical therapists and health researchers utilize mindfulness in treating psychiatric disorders and reducing psychological distress (13-15). Upon the development of this trend in other fields of study, many studies suggest the effectiveness of mindfulness training programs in improving job structures so that the results will include benefits, such as improved productivity and job performance (15-17), with reduced job burnout (19-20).
Against this background, few empirical studies have been conducted in Iran on mindfulness trainings and their effects on work environments. Many studies have been done on the positive effects of mindfulness trainings on non-occupational environments, using students or clinical samples. However, the empirical findings of such studies cannot be generalized to work environments. Therefore, the objective of the present study is to use the modified version of the mindfulness-based stress reduction method introduced by Klatt et al (2015) known as MIM to study the effects of mindfulness trainings in the workplace on a set of psychological and occupational variables in the statistical population of employees. The mindfulness in motion method has been designed in accordance with the time and space constraints of employees in the workplace. Therefore, this method is especially suitable for use in work environments. The distinctions between this method and the mindfulness-based stress reduction method lie in the time compression of the sessions (60 minutes per week), its focus on the individual performance of the pre-recorded practicum of meditations, and the daily sessions of yoga exercises proper for employees (21). Therefore, the present research seeks to answer the question of ‘Are mindfulness in motion-based trainings effective in resiliency, emotion regulation, and job stress?’
Materials and Methods
The present study was an experimental study using a pretest-posttest design, with control and experimental groups, and a follow-up phase (9 weeks later).
The statistical population of this study consisted of the employees of the National Iranian South Oil Company (NISOC) of Ahwaz City in 2017. To select the participants of the research, upon the permission of the company, according to the total number of employees (5000 people), and considering the number of the sample according to Krejcie and Morgan’s table (22), 300 employees were selected randomly from the departments of finance, non-industrial operations, production, technical affairs, engineering, procurement, planning, and HR. Next, each department was considered as a category, with the samples selected randomly based on the population size of each category. They were then examined in terms of the Five Facet Mindfulness Questionnaire (FFMQ). Those with scores one standard deviation below the mean and willing to attend training sessions, and based on inclusion and exclusion criteria, 40 employees were selected and assigned randomly (by coin flipping) to experimental and control groups (with 20 people in each of the experimental and control groups). The inclusion criteria of the study were doing daytime work, having a permanent or temporary employment contract, having at least a bachelor’s degree, having a minimum of four years of experience, having scores one standard deviation below the mean in the mindfulness questionnaire, and expressing interest and satisfaction in participating in the training sessions. In addition, the exclusion criteria were the use of psychiatric drugs, participation in other training sessions simultaneously, and absence from more than two training sessions. In this study, the following questionnaires were used for data collection:
Five Facet Mindfulness Questionnaire (FFMQ): A 39-item questionnaire was developed by Baer, Smith, Hopkins, Krietemeyer, and Tony in 2006 (23). In this questionnaire, the responses are rated based on a 5-point Likert scale ranging from 1 (never) to 5 (always), expressing the amount of the individual’s consent or opposition to each of the phrases, so a higher score indicates more mindfulness. Research findings in Iran show that this questionnaire has already been approved in terms of its validity and reliability. The internal consistency of the questionnaire, resulted from correlation among the components of the questionnaire and the total score, indicated that there was a significant correlation among all components and the total score. In addition, divergent validity showed that there was a significant negative correlation, with the coefficient of 0.21, between the total score of the questionnaire and that of the experimental avoidance questionnaire (24).
Resiliency questionnaire: In this study, the Conner-Davidson’s (2003) resiliency questionnaire was used to measure resiliency (25), and Mohammadi (2005) adapted it for use in the Iranian society. The questionnaire has 25 items and is rated on the Likert scale (never, rarely, sometimes, often, and always) with the scores being within the range of 1 to 5. Research findings in Iran showed that this questionnaire had acceptable validity and reliability. The Reliability of this scale has been reported based on the internal consistency method with the Cronbach’s alpha of 0.98 and high construct validity (26).
Emotion regulation scale: This scale is made up of 10 items as introduced by Gross and John in 2003 (27) and has two reappraisal (6 items) and suppression (4 items) subscales. The responses are presented based on the Likert scale (7 scores), ranging from 1 (totally disagree) to 7 (totally agree). The Persian version of the scale of ‘emotion regulation’ is standardized in the Iranian culture. The reliability of this scale has been verified based on the internal consistency method with the Cronbach’s alpha of 0.60 to 0.81, and desirable construct validity (28).
Job stress questionnaire: It is a tool designed by the UK’s Occupational Health and Safety Executive (HSE) to measure occupational stress indices. The questionnaire has 35 items with a 5-point Likert scale of never (1), rarely (2), sometimes (3), often (4), and always (5), formed based on the demand-control-support model. The revised version was presented by Cousins, MacKay, Clarke, Kelly, Kelly, and McCaig in 2004 (29). The questionnaire consists of the seven components of demand (8 items), control (6 items), peer support (4 items), managerial support (5 items), relationships (4 items), role (4 items), and change (3 items). In this study, the total score of job stress has been taken into account. The reliability and validity of the job stress questionnaire have been reported in an Iranian study. The convergent validity showed that there was a significant negative correlation, with a coefficient of 0.48, between the total score of the questionnaire and that of the general health questionnaire. The reliability of this questionnaire has been reported based on the internal consistency method with the Cronbach’s alpha of 0.78 (30).
The participants were told that their responses would remain confidential, so they responded to the self-report tools after their written informed consent was obtained. In addition, they were told that the training sessions would be held in a group to help them improve their psychological status, as a part of the study. Next, having filled out the informed consent form, the participants were enrolled. The mindfulness sessions consisted of eight 60-minute sessions (a session per week), with the sessions held at the Mental Health Center of the National Iranian South Oil Company. The mindfulness in motion-based training in the present study is a modified model based on Kabat-Zinn’s mindfulness-based stress reduction method (31), which is applied to work environments and referred to as mindfulness in motion (MIM) (27). The content of the courses included physical relaxation, meditation practice, yoga practice, body scan, mindful eating, listening to music, self-massage, and constructive discussions about stress management. The exercises were suitable for work environments. In all sessions, relaxing music was played to create a favorable atmosphere for learning. In addition, to involve the participants’ minds during the sessions, some questions were provided about weekly topics, and they were invited to share their responses with each other voluntarily. In sessions, emphasis was placed on the awareness of the habit patterns of stress responses and learning more productive behaviors. After the training sessions were completed, the participants responded to the questionnaires of the posttest.
The participants in both experimental and control groups responded to the research tools three times in the pretest, posttest, and the follow-up phase. In order to take account of ethical considerations at the end of the study, the control group received mindfulness trainings in the workplace after data collection in the follow-up phase.
Data analysis was performed using SPSS Statistics 21.0 and the multivariate analysis of covariance method (MANCOVA) at a 0.05 significance level. In addition, to ensure that the research groups were similar in terms of demographic features, the independent t-test, the Mann–Whitney U test, and the Chi-Square test were used.
Results
The mean and standard deviation of age (year) in the experimental group were 43.40 and 7.80, respectively; likewise, the mean and standard deviation of age (year) in the control group were 42.25 and 7.94, respectively. The results of the independent t-test showed that there was no significant difference between the two groups in terms of age (t= 0.466, sig= 0.644). The mean and standard deviation of the work experience (year) in the experimental group were 15.20 and 6.20, and 14.80 and 6.33 in the control group, respectively. In addition, the results of the independent t-test showed that there was no significant difference between the two groups in terms of the work experience (t= 0.202, sig= 0.841). From among the participants, 90% of them were male (18 people in the experimental group and 18 people in the control group), and 10% of them (4 people) were female (2 people in the experimental group and 2 people in the control group). In addition, 92.5% of the participants were married (19 people in the experimental group and 18 people in the control group), and 7.5% of them (3 people) were single (1 people in the experimental group and 2 people in the control group). The results of the Chi-Square test showed that there was no significant difference between the two groups in terms of marital status (Chi-Square = 0.360, sig= 0.548). Additionally, 70% (14 people) of the experimental group and 75% (15 people) of the control group had undergraduate degrees, and others had master’s degrees. The results of the Mann–Whitney U test showed that there was no significant difference between the participants in the two groups in terms of the level of education (U= 190, sig= 0.727).
Table 1 shows the descriptive findings of the research variables in the pretest, posttest, and the follow-up phase. Before performing the multivariate analysis of covariance, its assumptions were examined. The results of the Kolmogorov-Smirnov test showed that research data were normal for all the three test times (p> 0.05). In addition, due to the insignificance of the Levene’s test, the homogeneity of the variances of the research variables is established (p> 0.05). Box’s M test was used to examine the homogeneity of variance-covariance matrices, and the results showed that the value of Box’s M was insignificant. Thus, there was no significant difference between the groups in terms of the variance-covariance matrices (p> 0.05).

Table 2 shows that the observed F levels in the posttest and the follow-up phase have been 22.875 and 11.019, respectively, being significant at the 0.001 level. In other words, the results of the Wilks’ Lambda test imply a significant difference between the groups, with a significant difference observed in at least one of the variables in both experimental and control groups.

As table 3 shows, the difference between the mean scores of resiliency was significant in the posttest (P <0.001, F = 22.728) and the follow-up phase (P <0.001, F = 25.368) after controlling the scores of the pretest in both groups. In addition, the difference between the mean scores of reappraisal in the posttest (P <0.001, F = 15.578) and the follow-up phase (P <0.001, F = 6.594), and the difference between the mean scores of suppression in the posttest (P <0.001, F = 27.244) and the follow-up phase (P <0.001, F = 15.180) were significant after controlling the scores of the pretest in both groups. Besides, the difference between the mean scores of job stress in the posttest (P <0.001, F = 28.867) and the follow-up phase (P <0.001, F = 12.540) was significant after controlling the scores of the pretest in both groups. Based on the information presented in Table 1, it is concluded that mindfulness in motion-based trainings improved resiliency and reappraisal significantly and reduced suppression and job stress significantly.

Discussion
According to the findings of the present study, mindfulness trainings in the workplace are effective in improving employee resiliency, being consistent with the results of other studies (9, 21, 32, 33).
The findings of other studies consistent with the present one show that mindfulness trainings enhance distress tolerance, vigor, and resilience of employees but reduce employee perceived stress (9, 33). In addition, some research show that MIM enhances work engagement and resiliency (21), subjective sleep quality, and daytime dysfunction but reduces employee perceived stress (32).
By way of clarification, one can argue that mindfulness trainings in the workplace make an individual return to self, coax them out of the challenges of thoughts and problems into relaxation and flexibility, and increase resiliency. In mindfulness training sessions, individuals learn to be aware of themselves as well as the surrounding environment and conditions, and behave wisely in the workplace when in difficult situations, instead of showing immediate and unpleasant reactions. As a result, they show more resiliency to life difficulties. Mindful people know that pleasant and unpleasant conditions are transient, and that there is no permanent phenomenon. Thus, they cope with impermanent difficult conditions better and show more resiliency (34, 35, 36). Therefore, individuals receiving mindfulness trainings become more capable of dealing with internal and external stimuli in a direct manner and look at events with a non-judgmental attitude. As a result, there is a positive correlation between receiving mindfulness trainings and the level of employee resiliency (32, 33).
According to the results of the present study, mindfulness trainings in the workplace are effective in improving the emotional regulation of employees and can increase reappraisal and reduce suppression in them, being consistent with the results of past research (12, 15).
In addition, based on the research findings, mindfulness interventions are effective in reducing emotional exhaustion and improving job satisfaction (12). Such interventions are also effective in reducing psychological distress, stress, and burnout in employees (15). In explaining this finding, one can say that mindfulness in the workplace involves the skills and techniques by which employees experience a higher degree of consistency and are less affected by the stressors of the work environment. As a result, they will be able to reevaluate their emotional state cognitively and reduce the severity of the perceived stress. In other words, mindfulness trainings in the workplace make employees react less to stressful events. Therefore, as such trainings are associated with relaxation techniques, they will be more relaxed both physically and mentally. In addition, they will reevaluate issues better and focus cognitively on modifying their emotions. In addition, mindfulness trainings in the workplace, including reactions such as acceptance and psychological flexibility, are less likely to make individuals adopt unconventional strategies, such as the frequent avoidance of exposure to stressful events (10).
The findings of this study also showed that mindfulness in the workplace is effective in reducing job stress, being consistent with the results of other studies, directly and indirectly (18, 21, 30). Participants were asked to take a chair, close their eyes, and start loosening and tightening the parts of their bodies. Therefore, stress management skills were taught indirectly in everyday life, and given that one of the major areas of a person’s life is their job and work environment, this environment could be full of stressors. Therefore, due to mindfulness trainings in the workplace, the amount of job stress was reduced so that employees were less stressed after learning stress management skills at group meetings and enjoyed a higher degree of psychological well-being (27). The findings of this research were applied to the statistical population of the employees of the National Iranian South Oil Company (NISOC) of Ahwaz City, so in generalizing those findings to other statistical populations and employees of other organizations, one must act cautiously. It is suggested that similar studies be done on the employees of other organizations to get more comprehensive information about the effectiveness of mindfulness in motion-based trainings. Thus, it is suggested that in order of improving skills, such as resiliency and emotion regulation, and for reducing job stress, training courses be run based on mindfulness interventions in the workplace.
Conclusion
The results indicated the high effectiveness of mindfulness in motion-based trainings in improving resiliency and emotion regulation, and reducing the job stress of employees in the posttest and the follow-up phase. In other words, mindfulness in motion-based trainings, apart from having positive psychological and occupational consequences in the short run, have positive consequences in the long run. The interventions included formal and informal exercises that were done continuously. Therefore, the employees learned after the end of the course to do formal exercises, such as relaxation exercises, with their everyday life influenced informally by participation in mindfulness in motion-based trainings.
