Abstract: BACKGROUND: Desire2Move (D2M) is an 8-week team-based, workplace program that incorporates competition and self-monitoring to encourage physical activity (PA). OBJECTIVE: The purpose of this pilot study was to evaluate the effectiveness of a self-compassion (SC) intervention within the existing workplace PA program. METHODS: University employees (n  = 20) were assigned to a SC treatment group or an attention control group. Participants logged their PA minutes using MapMyRun . Treatment group. participants received a 7-week, SC podcast intervention. Participants self-reported PA, SC, and demographic information at pre- and post-intervention. Separate ANOVAs were used to determine group differences. …RESULTS: There was not a statistically significant group x time interaction for SC, F (1, 18) = 0.02, p  = 0.90, or main effects for time, F (1, 18) = 0.28, p  = 0.61, or group, F (1, 18) = 1.70, p  = 0.21, g  = –0.42 [95%CI = –3.13, 2.29]. There were not significant differences between groups for total PA minutes during D2M, F (1, 18) = 2.15, p  = 0.16, g  = –0.63 [–1.53,0.27]. Overall, participants engaged in more than the recommended levels of PA each week. CONCLUSIONS: This pilot study provided feedback and guidance for future online SC training within a workplace PA intervention. Show more

Abstract: BACKGROUND: Fitness could influence task performance in police officers. Limited research details relationships between different fitness characteristics and police-specific tasks. OBJECTIVE: Determine relationships between anaerobic and aerobic capacity with police-specific task performance. METHODS: Data for 308 recruits was analysed. Fitness tests included: push-ups, sit-ups, and mountain climbers (muscular endurance); pull-ups (strength); vertical jump (VJ) and 2 kg medicine ball throw (MBT; power); 75-yard pursuit run (75PR; change-of-direction speed); 201 m run (anaerobic capacity); 2.4 km run and multistage fitness test (aerobic capacity). Police tasks included: 99-yard obstacle course (99OC); 74.84 kg body drag (BD); chain link fence (CLF) and solid …wall (SW) climbs; and 500-yard run (500R). Partial correlations controlling for sex and linear regression calculated relationships between fitness and job tasks. RESULTS: 99OC correlated with all assessments; BD only with 75PR. CLF related to the power and aerobic capacity tests, pull-ups, and 201 m run. SW related to VJ, 75PR, pull-ups, sit-ups, 201 m run, and aerobic capacity. 500R related to all except the MBT and 2.4 km run. 75PR and VJ predicted 4/5 tasks. CONCLUSIONS: Police research has shown the importance of muscular endurance and aerobic capacity. Specific to this studies’ correlations, the value of power and change-of-direction speed development for task performance was indicated. Show more

Abstract: BACKGROUND: Law enforcement agencies often include fitness testing as part of the hiring process. However, it can be months from this testing to when a recruit starts academy. OBJECTIVE: To determine fitness changes from hiring to academy in recruits who graduate (GRAD) or separate (SEP; do not complete) from academy. METHODS: Analysis on recruits from one agency, split into GRAD (n  = 436) and SEP (n  = 78) groups, was conducted. These tests were conducted during initial hiring and academy: push-ups, sit-ups, and arm ergometer revolutions in 60 s; 75-yard pursuit run (75PR); and 2.4 km run. Data were analyzed …via a two-way repeated measures ANOVA. Change scores were derived between hiring and academy data for both groups, and analyzed via independent samples t-tests. RESULTS: Push-ups, 75PR, arm ergometer, and 2.4 km run generally improved (p ≤0.001). There were no significant between-group interactions or differences in performance changes for GRAD and SEP recruits. SEP recruits tended to have lesser fitness test performance compared to GRAD recruits. CONCLUSIONS: GRAD and SEP recruits showed some fitness improvements between initial hiring through to academy. However, SEP recruits with lesser muscular endurance, running speed, and aerobic capacity during hiring did not substantially improve by academy, which likely impacted their academy survivability.

Abstract: BACKGROUND: Health problems due to musculoskeletal disorders (MSD) and common mental disorders (CMD) result in costs due to lost productivity. OBJECTIVE: This study aimed to increase knowledge of employers’ productivity loss due to employees’ presenteeism and sickness absence. METHODS: A web questionnaire was sent to employers of workers who were sick-listed for more than 30 days due to MSD or CMD, response rate: 50%, n  = 198. Presenteeism and the impact on productivity before and after sick leave, and the performance of work tasks by replacement workers during sick leave, were measured using supervisors’ ratings. …RESULTS: The average loss of productivity per sick-leave case amounted to almost 10 weeks, 53%of productivity loss was attributable to presenteeism and 47%to lower productivity by replacement workers. Employees with a CMD diagnosis had significantly higher presenteeism-related productivity loss than those with MSD. CONCLUSIONS: Employers experienced substantial productivity loss associated with employees’ presenteeism and sick leave. Whether the supervisory rating of presenteeism is preferable to employee self-rating needs to be studied further. The long duration of presenteeism is counter-productive to resource-efficient organisations and indicates the need for improved supervisory skills to identify workers with poor health, both before and after sick leave.

Abstract: BACKGROUND: Residual capacity evaluation via neuropsychological testing can facilitate the development of a rehabilitation plan in patients following a traumatic brain injury (TBI). OBJECTIVE: This study aimed to confirm the tasks that patients must perform well for early return to work (RTW) following TBI using the Wechsler Adult Intelligence Scale III (WAIS-III). METHODS: In total, 40 male and 13 female patients who suffered from neurobehavioral disabilities following TBI were recruited and classified into two groups: the successfully returned to work group (SRTW-G; n  = 22) and the unsuccessfully returned to work group (USRTW-G; n  = 31). The …outcomes assessed by WAIS-III and the time to RTW were compared between the SRTW-G and USRTW-G groups. Multiple logistic regression, multiple regression analysis, and Cox regression were employed to assess differences between the groups. RESULTS: The Comprehension and Letter-Number Sequencing subtests of the WAIS-III were significantly correlated with early RTW more than the other subtests. CONCLUSIONS: We found that, as reflected in the two subtests, patients with TBI must be able to perform well in the following tasks for early RTW: Retention of information for short time periods, information processing, and social judgment based on the knowledge of the patient’s experience.

Abstract: BACKGROUND: Occupational skin disease (OSD) is a common health issue in the food processing sector. However, risk factors for OSD are suspected to differ according to the nature of the operation. OBJECTIVE: To ascertain if the risk factors for OSD vary depending on the type of food processing operation, namely meat processing vs. a commercial bakery. METHODS: Participants were asked to answer questions regarding workplace exposures and the current skin condition of their hands. Bivariate analyses were conducted to identify differences between the two participating operations. RESULTS: The meat processing workers were more likely …to have wet work exposure, used hand sanitizer more often and changed their gloves more frequently. These findings from meat processing represented a statistically significant difference compared to the commercial bakery workers. Also, workers from meat processing reported more severe skin symptoms. CONCLUSIONS: Risk factors for OSD apparently differ between types of food processing operations. Differences in the nature of skin symptoms were also found between the two participating operations. It is therefore suggested that future studies examining OSD within the food processing sector should evaluate this health effect based on the nature of operations rather than the sector as a whole.

Abstract: BACKGROUND: Multiple sclerosis (MS) is a neurological chronic disease that causes a number of physical, cognitive and emotional symptoms. The identification of these factors will allow mitigating unemployment and improve quality of life of patients. The Buffalo Vocational Monitoring Survey (BVMS) is a tool to characterize Work-Challenged patients. OBJECTIVE: To describe and analyze BVMS data in people with multiple sclerosis (PwMS) from Argentina. To study the association with physical, cognitive and psychiatric morbidity in employed patients, comparing the performance of MS Work-Challenged and MS Work-Stable patients, with and without accommodations. METHODS: 119 MS patients were administered …the Argentina adaptation of the BVMS, and completed measures of physical disability, fatigue, depression, cognitive processing speed, memory and verbal fluency. RESULTS: 65.54% of the patients were employed and 19.32% were unemployed, the remaining having roles of housewife, students and disability retirees. Within the employed subgroup, 60.26% were working as employees and 39.74% were self-employed. Cognitive and clinical variables differentiate patients with and without negative events and accommodations (p  >  0.05). CONCLUSIONS: This Spanish version BVMS is considered a new tool to monitor employment difficulties in Spanish-speaking MS patients. MS Work-Challenged had a higher depression, fatigue and worse performance in cognitive variables. Show more

Abstract: BACKGROUND: Office workers spend significant time in sedentary behaviors. Exploration of interventions to address this concern is warranted. OBJECTIVE: This study explored the impact of individualized goals and ergonomic modifications on sedentary behaviors and perceived health and well-being among office workers. METHODS: A six-week, one-group, pre- and post-test design was utilized to assess sedentary behaviors and perceptions of health and well-being among office workers using the RAND 36-Item Short Form Survey (SF-36), Numerical Pain Rating Scale (NPRS), Pittsburgh Sleep Quality Index (PSQI), Sedentary Behavior Questionnaire (SBQ), actigraphy, and a workstation assessment. RESULTS: Statistically significant …improvements were noted from pre- to post-test on the RAND SF-36 for energy/fatigue (p  = 0.000) and emotional well-being (p  = 0.049) and subjective sleep quality using the PSQI (p  = 0.005). Participants (n  = 17) could set up to two goals related to health and well-being. A majority of the 31 established goals were met: increase physical activity (n  = 11/16), reduce sedentary behavior (n  = 8/11), and improve personal health (n  = 3/4). CONCLUSIONS: The use of individualized goals and ergonomic modifications is effective for addressing perceived health and well-being among office workers. However, limited statistical significance was found regarding the impact of these interventions on sedentary behaviors or activity levels. Show more

Abstract: BACKGROUND: The job demands on nurses have increased. Conflict between work life and family life may lead to stress and lower work engagement. Consequently, nurses may choose a different career path or leave the profession. OBJECTIVE: Examine the extent to which perceived job demands (interpersonal conflicts at work and workload), work engagement, work-family conflict and family-work conflict are associated with turnover intentions, and examine a possible moderating effect of work-family conflict on the relationship between the intention to leave the nursing profession, job demands and work engagement. METHODS: Cross-sectional study using Hobfoll’s Conservation of Resources theory. …Data were collected from a sample of 807 registered nurses (RNs) from western Sweden. Tests of moderation were conducted using the PROCESS software macro developed by Andrew F. Hayes. RESULTS: Work-family conflict was a significant moderator in the relationship between the intentions to leave the nursing profession and work engagement as well as interpersonal conflicts at work. Low work engagement, high work-family conflict and high job demands intensify turnover intentions in well-educated and well-experienced nurses. CONCLUSIONS: The results imply that work-family conflict has a greater impact when RNs experience lower work engagement. In other words, higher motivation implies a lower moderation effect of work-family conflict. Managers should promote a positive working climate by listening to and providing nurses with opportunities to develop their skills. By so doing, managers can gain better understanding of nurses’ resources, knowledge and work situation, thus strengthening nurses’ confidence and ability to practice their profession. Show more

Abstract: BACKGROUND: Unemployment is common in people with multiple sclerosis (PwMS) and might be prevented if factors associated with work loss are identified. OBJECTIVE: We aimed to assess the impact of multiple sclerosis (MS) on employment status in a cohort of PwMS from Argentina and to evaluate their association with anxiety, depression, fatigue and disability. METHODS: A cross-sectional study was conducted to assess employment in PwMS using an anonymous, self-administered questionnaire, which also included the Hospital Anxiety and Depression Scale, Fatigue Severity Scale and Expanded Disability Status Scale. The data was compared between employed (full-time vs. part-time) …vs. unemployed (looking for vs. not looking for work) PwMS. Univariate and multivariate models were designed to identify factors independently associated with unemployment. RESULTS: Among the 167 PwMS, 120 (71.6%, full-time = 65%) were employed, and 47 (28.4%, looking for work = 27.6%) were currently unemployed. Age, gender, and duration of disease were similar in both groups. Univariate analysis showed that anxiety, depression, fatigue and disability were significantly associated with unemployed PwMS. However, only disability (OR = 1.36 (1.08–1.70), p  = 0.007) was independently associated with unemployment after applying multivariate analysis (logistic regression). CONCLUSION: Nearly one-third of PwMS from this sample in Argentina were unemployed. Neuropsychological factors and disability were associated with unemployment status. Show more

Abstract: BACKGROUND: A just culture is one in which the reporting of errors and near misses is supported without fear of retribution. The relationship of just culture and psychosocial factors at work has not been explored sufficiently in the literature. OBJECTIVE: To investigate the perception of just culture and its association with socio-demographic and work-related psychosocial factors among 302 employees in an industrial setting in Iran. METHODS: Just culture was assessed using the Just Culture Assessment Tool, and the Copenhagen Psychosocial Questionnaire was used for evaluation of psychosocial work factors (including influence at work, meaning of work, …commitment to the workplace, predictability, rewards, quality of leadership, social support from supervisors, trust, and justice and respect). Data were analysed using t test, analysis of variance (ANOVA), and general linear regression analysis. RESULTS: The results indicated that the employees had a fairly positive view on their organisation’s just culture, though there were some areas such as trust and balance that needed further attention. The psychosocial issues (particularly commitment to the workplace, meaning of work, social support from supervisors, and rewards) were not adequate from the employees’ perspective. Predictability, rewards, and quality of leadership, were the significant psychosocial predictors of just culture in a multivariate regression model. CONCLUSIONS: The findings highlight the areas that need to be considered to improve the experience of organisational just culture, which is important from the point of view of prevention of safety errors and incidents.

Abstract: BACKGROUND: Deep breathing exercises are known to help decrease stress. Wearable and ambient computing can help initiate and support deep breathing exercises. Most studies have focused on a single sensory modality for providing feedback on the quality of breathing and other physiological data. OBJECTIVE: Our research compares different feedback modalities on an individual’s experience and ability to perform breath-based techniques at work. METHODS: We designed three different interactive prototypes that used light, vibration and sound feedback modalities. We tested each prototype with 19 participants whilst they were performing typical work tasks in a naturalistic setting, followed …by semi-structured interviews. RESULTS: We found that sound was the most successful feedback for the majority of participants, followed by vibration and ambient light. We developed an analytic tool, the Extended Cycle of Awareness, to facilitate understanding of the patterns of awareness and the flow of experience generated by participant interaction with prototype systems that provide feedback on the quality of breathing. Participants followed one of three different types of patterns: (1) ignoring the feedback; (2) not understanding the feedback and being overwhelmed by it; (3) successfully using the feedback to initiate deep breathing and reflect on the change in the quality of breathing. CONCLUSIONS: We offer a set of design recommendations for crafting interactive systems to support deep breathing at work, including personalization, designing for the cyclical process of attention and awareness, and designing for reflective practice.

Abstract: BACKGROUND: Nursing home professionals belong to one of the most vulnerable occupational groups when it comes to type II workplace violence. Cared-for elders carry out violent actions that affect both the health of professionals and the organisation and services provided in nursing homes. Taking notice of this phenomenon and getting to know its magnitude is the first step for preventive action and intervention to take place. In Catalonia, it was the medical community that started to notice workplace violence. However, the frequency of this phenomenon had not been investigated. OBJECTIVE: This study was carried out with the main …goal of learning about the phenomenon of type II workplace violence in nursing homes. METHODS: 433 nursing home professionals of Catalonia volunteered to take part in this study. They remained anonymous and their data was treated confidentially. RESULTS: 68.6%(IC 95%: 64.1–73.1) of the nursing home professionals admitted to having been attacked by the senior citizens residing in these nursing homes. The occupation and self-perceived stress level of the professionals were related to the consideration of aggression. Verbal abuse was the type of aggression that targeted professionals reported the most. In 61.3 %of the cases, they were attacked by both male and female patients. CONCLUSION: The results of the study reveal that nursing home professionals are assaulted and/or attacked by the residents they tend to. Show more

Abstract: BACKGROUND: Managers have an important role in the creation of workplace conditions that prevent sick leave and lead to high performance. In Lean, the assumption is that people are the source for continuous improvements. There is a need for more knowledge about what kind of leadership can help managers in a Lean context to create workplace conditions for less sick leave and higher performance. OBJECTIVE: The purpose of this study was to examine how productivity and rate of sick leave changed at a stainless wire manufacturing unit after implementing a new leadership approach based on Sense of Coherence …theory (SOC) and Lean philosophy. METHODS: In this case study, interventions coupled with productivity, quality and sick leave evaluations through the company’s key performance indicators were performed. The follow-up was also based on narrative descriptions from the management team in the course of four meetings during the intervention. Notes were taken and analyzed regarding perceived outcomes of the intervention. RESULTS: The results showed that leadership based on SOC and Lean philosophy is positively correlated with productivity per worker, as was the amount of yearly production that met the quality specifications. The amount of sick leave decreased during the period of the intervention compared to before the intervention. CONCLUSIONS: Changes in management contribute to productivity. Combining Lean tools and Lean philosophy with the Sense of Coherence theory (SOC) as a base for leadership can influence productivity and decrease the rate of sick leave. Show more

Abstract: BACKGROUND: Forward head posture (FHP) is the most common malposition in the head and neck area. With the growing use of digital devices, the prevalence of FHP may be expected to increase dramatically. Thus far, FHP has been evaluated only in the sagittal plane. OBJECTIVE: The objective of this study was to measure angles and indices from anatomical landmarks in the frontal plane and determine the possible correlations between these variables and craniovertebral angle (CVA) as an index of FHP in the sagittal plane. METHODS: Fifty eight healthy individuals (29 men, 29 women) between 18 and …40 years old participated in this cross-sectional study. Participants were evaluated with an 8-camera motion analysis system. After markers were placed on predetermined landmarks, the participants were asked to maintain their head and neck in the neutral position for 5 seconds. Then participants induced FHP by flexing and lowering their head. The correlation between CVA and a set of angles and indices was calculated at the moment of FHP induction. RESULTS: A moderate correlation was observed between 3-D CVA and the angle formed between the sternum and both tragi for the whole sample and separately in both sexes. A moderate negative correlation was observed between 3-D CVA and height, weight, and BMI in women. A moderate negative correlation was observed between 3-D CVA and height, weight, BMI, and hours on digital devices in men. CONCLUSIONS: Changes in CVA in the sagittal plane can be predicted from changes in the angle formed between the midpoint of the sternum and the left and right tragi in the frontal plane. Show more

Abstract: BACKGROUND: In low back pain, multifidus muscle fibers reportedly exhibit increased stiffness. Low back pain was associated with lumbodorsal muscle fatigue. There is no report of using shear modulus to verify the mechanism of an immediate effect of exercise on low back pain. Here, temporary lumbodorsal muscle fatigue was created, simulating fatigue-related nonspecific low back pain. OBJECTIVE: To assess the effect of standing back extension exercise on fatigued lumbodorsal muscle based on the results of multifidus muscle elasticity measured using shear wave elastography. METHODS: Thirty-three healthy subjects were randomly divided into three groups. The subjects …performed the Biering-Sorensen test as the fatigue-task of the lumbodorsal muscle before the standing back extension exercise. The fatigue-exercise group exercised five sets after completing the fatigue-task. The fatigue-non-exercise group remained standing for the same duration as the fatigue-exercise group without doing the exercise after the fatigue-task. The non-fatigue-exercise group exercised five sets of without performing the fatigue-task. As intra-group and inter-group factors, the shear modulus of the multifidus muscle was compared before and after the exercise. RESULTS: The shear modulus of the multifidus muscle after the standing back extension exercise was significantly lower in the fatigue-exercise group, and no significant decrease was observed in the fatigue-non-exercise and non-fatigue-exercise group. CONCLUSIONS: The standing back extension exercise improved the shear modulus of the fatigued multifidus muscle. Therefore, it was suggested that the change in the elasticity of fatigued muscle might lead to the prevention of low back pain caused by muscle fatigue. Show more

Abstract: BACKGROUND: Work-related Musculoskeletal Disorders (WMSDs) are major challenges in the occupational health services industry. Dental practitioners are regularly subjected to ergonomic risks, which can cause Musculoskeletal Disorders (MSDs) in various body regions. OBJECTIVE: This comparative cross-sectional study aimed to investigate MSDs and select a proper ergonomic risk assessment method in dental practice. METHODS: This study was conducted on 70 dentists and 70 administrative staff of dental offices (comparison group) from Shahroud, Iran. The Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) and two observational ergonomic risk assessment methods, including Quick Exposure Check (QEC) and Rapid Entire Body Assessment (REBA), …were utilized. RESULTS: The results suggested that the mean score of musculoskeletal discomforts was significantly higher in dentists than in the administrative personnel. Additionally, the results of multiple regression analysis technique inferred that job tenure, working hours, and age had a significant impact on total MSDs. Regular exercise was found to significantly reduce neck discomfort complaints. It was also found that QEC was more effective in predicting musculoskeletal discomforts compared to REBA. CONCLUSION: Considering the high incidence of WMSDs in dentists, various interventional measures revolving around ergonomically redesigned workstations, enhanced physical working conditions, and ergonomic training courses are suggested.

Abstract: BACKGROUND: Work-related fatigue can cause disruption in mental and physical activities of the workers. Considering the importance of recovery from fatigue in emergency services, as seen in firefighting duties, the preparation and validation of the Need For Recovery Scale (NFRS) questionnaire can be useful and effective. OBJECTIVE: This study assessed the reliability and validity of the Persian version of Need For Recovery Scale among industrial firefighters. METHODS: Need for recovery scale contains 11 questions. First, a questionnaire was translated using backward-forward method. Then, for measuring validity of the questionnaire, the opinions of 10 experts in related …fields were obtained. Content Validity Index (CVI) and Content Validity Ratio (CVR) were calculated. The reliability was determined through 107 questionnaires completed by the industrial firefighters. RESULTS: The average age of the firefighters in this study was 37.5 years and they had an average of 10 years of work experience. The mean Need For Recovery Index from fatigue was 33.03 for the study population. Of the first 11 questions, 9 questions in the original NFRS showed a satisfactory level of CVR. The Content Validity Index and Cronbach’s α were 0.89 and 0.77 respectively. CONCLUSION: Based on the results, the Need For Recovery Scale is a reliable tool for assessing fatigue and revealed an acceptable level of validity and reliability that makes it usable for fatigue assessment in the industrial firefighters.

Abstract: BACKGROUND: Stress is common among police personnel leading to several negative consequences. OBJECTIVE: We performed a systematic literature review to identify risk factors for stress among police officers. METHODS: We searched PubMed and Scopus electronic databases through to July 2018 and we conducted this review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The Newcastle-Ottawa scale was used for studies quality assessment. RESULTS: After selection, 29 cross-sectional studies met the inclusion criteria and included in the review. The average quality of studies was low since no study was rated …as having low risk of bias, three studies (10.3%) as moderate risk and 26 studies (89.7%) were rated as having high risk of bias. Stress risk factors were summarized in the following categories: demographic characteristics; job characteristics; lifestyle factors; negative coping strategies and negative personality traits. CONCLUSIONS: Identification of stress risk factors is the first step to create and adopt the appropriate interventions to decrease stress among police personnel. The early identification of police officers at higher risk and the appropriate screening for mental health disorders is crucial to prevent disease and promote quality of life. Show more

Abstract: BACKGROUND: Many work-related fatalities happen every year in electricity distribution companies. This study was conducted to model accidents using the time series analysis and survey descriptive factors of injuries in an electricity distribution company in Tehran, Iran. METHODS: Data related to 2010 to 2017 were collected from the database of the safety department. Time series and trend analysis were used for data analyzing and anticipating the accidents up to 2022. RESULT: Most of the accidents occurred in summer. Workers’ negligence was the reason for 75% of deaths. Employment type and type of injuries had a significant …relationship (p  <  0.05). CONCLUSION: The anticipating model indicated occupational injuries are going to have an increase in the future. A high rate of accidents in summer maybe because of the warm weather or insufficient skills in temporary workers. Temporary workers have no chance to work in a year like permanent workers, therefore acquisition experiences may be less in them. Based on the estimating model, management should pay attention to those sectors of the company where most of the risky activities take place. Also, training programs and using personal protective equipment can help to protect workers in hazardous conditions. Show more
