Development and Validation of a Resilience Skills Questionnaire for Health Sector Professionals Based on Social Cognitive Theory.

Good resilience skills support effective and timely adjustment to demanding situations in the workplace. Existing tools are insufficient to develop and evaluate workplace interventions to improve employee's resilience skills. The aim of this study was to develop and validate a Resilience Skills Questionnaire (RSQ) using the key constructs of social cognitive theory-self-efficacy, self-regulation, and social support-as a theoretical framework. Following DeVellis' guidelines for scale development, first an expert panel of thirteen professors was recruited to support the item development stages and determine content validity. At this stage, the initial pool of 38 items was reduced to 25 items and CVR and CVI were calculated as 0.92 and 0.93, respectively, indicating good content validity. A second panel of ten health professionals confirmed face validity. An online survey comprised of the 25 developed items was then completed by 336 health professionals working in urban healthcare centers in Shiraz, Iran, in November 2021. The data were used to assess the psychometrics of the questionnaire according to its hypothesized three-dimensional structure. Confirmatory factor analysis yielded a final model of seventeen items in three dimensions, self-efficacy (six items), social support (six items), and self-regulation (five items), with good psychometric properties (χ2/df = 2.44 (p < 0.001), RMSEA = 0.06, GFI = 0.92, AGFI = 0.90, IFI = 0.93, CFI = 0.93). All standardized factor loadings were significant (p < 0.001). Internal consistency, as measured by Cronbach's alpha, was very good: RSQ (0.90), self-efficacy (0.86), social support (0.83), and self-regulation (0.86). Based on these results, the RSQ can be used as a standard and valid measure to develop and evaluate the effect of educational intervention programs to improve resilience skills and reduce job stress.

Developing a model for predicting safety performance of nurses based on psychosocial safety climate and role of job demands and resources, job satisfaction, and emotional exhaustion as mediators.

BACKGROUND: The present study aimed to develop a model for predicting the safety performance of nurses based on psychosocial safety climate (PSC) and the role of job demands and resources, job satisfaction, and emotional exhaustion as mediators. METHODS: A cross-sectional study using structural equation modeling (SEM) was carried out among nurses in Iran. Data were collected using the Psychosocial Safety Climate questionnaire, Neal and Griffin's Safety Performance Scale, the Management Standards Indicator Tool, the Effort-Reward Imbalance questionnaire, the Michigan Organizational Assessment Job Satisfaction subscale and the Maslach Burnout Inventory. RESULTS: Surveys were distributed to 340 nurses provided informed consent. After removing incplete surveys, data from 280 partipants were analysed. The completion rate was 82.35%. The SEM results indicated that PSC can directly and indirectly predict nurses' safety performance. The final model showed an acceptable goodness of fit (p = 0.023). It indicated that PSC, job demands, and job satisfaction were directly related to safety performance, and also that PSC, emotional exhaustion, job resources, and job demands were all indirectly related to safety performance. Also, PSC had a significant relationship with all mediator variables, and job demands had direct effect on emotional exhaustion. CONCLUSIONS: The current study presented a new model for predicting safety performance in nurses in which PSC, both directly and indirectly, plays an important role. In addition to paying attention to the physical aspects of the workplace, healthcare organizations should also take into account PSC to improve safety. Next steps in reducing safety issues in nursing is to develop intervention studies using this new evidence-based model as a framework.

Understanding Moral Injury in Frontline Health Care Professionals 2 Years After the Onset of COVID-19.

ABSTRACT: Throughout the COVID-19 pandemic, health care professionals have worked in morally challenging situations. The aim of this research was to investigate the predictors of moral injury in United Kingdom frontline health care professionals working in a variety of roles 2 years after the onset of the pandemic. A cross-sectional survey was conducted January 25-February 28, 2022. A total of 235 participants answered sociodemographic, employment, health, COVID-19-related questions, and the 10-item Moral Injury Symptom Scale-Healthcare Professional version. Nearly three quarters had experienced moral injury. Twelve significant predictors of moral injury were entered into a backward elimination binominal logistic regression. The final model included five independent predictors that explained 25.4% variance in moral injury (χ 2 [5, N = 235] = 45.7, p < 0.001). Odds of moral injury were significantly raised in young health care professionals (<31 years), smokers, and those reporting low workplace confidence, not feeling appreciated, and feeling burned out. The findings support interventions to relieve moral injury in frontline health care professionals.

Understanding risk factors for musculoskeletal disorders in Iranian housewives: Development of a comprehensive health promotion behavior model.

BACKGROUND: Chronic musculoskeletal problems are a major source of disability, reduced productivity and poor quality of life. Prevalence of musculoskeletal disorders among Iranian housewives is particularly high. Understanding how housework causes the injuries, mobility restrictions and pain associated with musculoskeletal disorders is vital to developing health promotion behavior models to support intervention. The aim of this qualitative study was to explore the experiences of housewives with musculoskeletal disorders and, according to the risk factors identified, to develop a comprehensive behavior change framework to facilitate implementing a musculoskeletal health-promoting training intervention for women. METHODS: Twenty-four in-depth interviews were conducted with Iranian housewives aged 20-65 years experiencing musculoskeletal pain over a 13-month period from September 2020 to October 2021. The conventional content analysis approach was used to interrogate the data. The transcript of each interview was considered a unit of analysis, and data analysis was performed using MAXQDA2018 software. RESULTS: The analysis of the interview data provided 1432 meaning units. From these codes, a conceptual framework was developed. This comprehensive model is comprised of 24 subcategories, eight categories and three themes: Individual and social predictors of MSDs and their control, Risk factors for MSDs, and Prevention and treatment of MSDs. Altogether the developed conceptual framework specified the multiple risk factors for MSDs in housewives. The findings were aligned to various health promotion models, and it was seen that ecological models, especially the Theory of Triadic Influence, can be very helpful as a supportive roadmap to implementing multilateral interventions to improve the quality of life of housewives. CONCLUSIONS: This study developed an evidence based comprehensive model that identifies the individual, psychosocial, and cultural factors that influence the status of MSDs in women's domestic work to support the development and implementation of effective ergonomic interventions to manage potentials for MSDs.

Effectiveness of a transactional model-based education programme for enhancing stress-coping skills in industrial workers: a randomized controlled trial.

The aim of this study was to examine the effectiveness of a stress management educational intervention programme based on the Transactional Model of Stress and Coping (TMSC) among industrial workers. Participants were 106 employees of a power plant in Iran, randomly assigned into an intervention group and a control group. The intervention comprised active and participatory methods to enhance employees coping skills and it was delivered in six face-to-face sessions. Data was collected using the Ways of Coping Questionnaire, the Multidimensional Scale of Perceived Social Support, the Perceived Stress Scale, and the Spiritual Well-Being Scale at baseline and three months after the intervention. We found mean scores of distancing, self-controlling, seeking social support, escape-avoidance, planned problem-solving, positive reappraisal, total coping skills, perceived social support, and spiritual well-being significantly differed at follow-up compared to baseline in the intervention group, but not in the control group. There was also a significant difference in the mean score of perceived stress between the two groups. We conclude that the educational intervention based on the TMSC was effective in improving coping skills and reducing perceived stress. We suggest that interventions based on the TMSC model can be supportive in workplaces where job stress is common.

Development and validation of a task load index for process control room operators (PCRO-TLX).

Process control room operators (PCRO) perform a range of complex cognitive safety-critical tasks. The aim of this exploratory sequential mixed methods study was to develop an occupation specific tool to measure the task load of PCRO using NASA Task Load Index (TLX) methodology. Participants were 30 human factors experts and 146 PCRO at two refinery complexes in Iran. Dimensions were developed via a cognitive task analysis, a research review, and three expert panels. Six dimensions were identified: perceptual demand, performance, mental demand, time pressure, effort, and stress. Data from 120 PCRO confirmed that the developed PCRO-TLX has acceptable psychometric properties, and a comparison with the NASA-TLX confirmed that perceptual, not physical, demand was relevant for measuring workload in PCRO. There was a positive convergence of scores of the Subjective Workload Assessment Technique and the PCRO-TLX. This reliable tool (α = 0.83) is recommended for risk assessing the task load of PCRO.Practitioner summary: There are benefits of having a specific tool to measure task load in safety critical roles. Thus, we developed and validated an easy-to-use targeted tool, the PCRO-TLX, for process control room operatives. Timely use and response will assure optimal production alongside health and safety in an organisation.Abbreviations: PCRO: process control room operator; TLX: task load index; PCRO-TLX: process control room operator task load index; NASA-TLX: National Aeronautics and Space Administration task load index; SWAT: subjective workload assessment technique; DALI: driving activity load index; SURG-TLX: surgery task load index; SIM-TLX: virtual reality simulation task load index; VACP: visual, auditory, cognitive and psychomotor; CVI: content validity index; CVR: content validity ratio; RMSEA: root mean square of error approximation; GFI: goodness of fit index; AGFI: adjusted goodness of fit index; CFI: comparative fit index; ANOVA: analysis of variance; CI: confidence interval.

The study protocol for the randomized controlled trial of the effects of a theory-based intervention on resilience, social capital, psychological wellbeing, and health-promoting lifestyle in healthcare workers.

BACKGROUND: The workplace has been identified as a key determinant of health status. There is evidence of innumerable health problems among employees, particularly healthcare workers. Against this background, a holistic-systemic approach together with a good theoretical framework is required to reflect on this issue, and to support the design of effective interventions to promote the health and wellbeing of the given population. The present study aims to evaluate the effectiveness of an educational intervention in improving resilience, social capital, psychological wellbeing, and health-promoting lifestyle in healthcare workers, utilizing the Social Cognitive Theory integrated into the PRECEDE-PROCEED model. METHODS: This randomized controlled trial will be performed on a large sample of the employees working in two healthcare centers in the city of Shiraz, Iran. The study will proceed with the healthcare workers of one city being given the educational intervention and the healthcare workers of the other city serving as a control group. Using a census method, all healthcare workers in the two cities will be informed of the trial and its purpose, and then invitations to join the study will be issued. The minimum sample size required has been calculated as 66 individuals in each healthcare centers. Recruitment to the trial will by systematic random sampling of eligible employees who submit an expression of interest in joining the trial, and subsequently give informed consent. Data will be collected through a self-administered survey instrument at three stages: at baseline, and both immediately and three months after the intervention. The experimental group members should participate in at least eight of the ten weekly educational sessions of the intervention and complete the surveys in the three stages. There is no educational intervention for the control group, and they simply experience some routine programs, and complete the surveys at the same three timepoints. DISCUSSION: The findings will provide evidence for the possible effectiveness of a theory-based educational intervention to improve resilience, social capital, psychological wellbeing, and health-promoting lifestyle among healthcare workers. If the educational intervention is found to be effective, then its protocol will be exploited in other organizations to boost resilience. Trial registration IRCT20220509054790N1.

Persian version of the work design questionnaire: measurement of its psychometric characteristics.

BACKGROUND: Work design questionnaire (WDQ), as a comprehensive and integrative tool, is one of the most important instruments frequently used to assess work characteristics. The aim of this study was to measure the psychometric characteristics of the Persian version of WDQ. METHODS: Translation and cross-cultural adaptation procedures were applied in translating the original WDQ into Persian. A total of 270 participants participated in this study. The validity of the questionnaire were measured using face validity, content validity, convergent validity, and construct validity based on confirmatory factor analysis (CFA). Reliability was assessed through internal consistency. RESULTS: Mean content validity index was 0.95. The CFA results indicated support for a 21-factor solution. There were significant correlations between dimensions of WDQ and both job satisfaction and perceived stress. Cronbach's alpha of all items was 0.87. CONCLUSION: Results indicated that the WDQ exhibited very good psychometric properties and can be applied as a useful tool to assess work characteristics among Iranian employees. Accordingly, the authors recommend its administration in future studies. The work characteristics was significantly associated with job satisfaction and job stress. Therefore, improved work design would reduce negative consequences, such as job stress, and increase positive behaviors, such as job satisfaction.

Assessment of Masks Used by Healthcare Workers: Development and Validation of a Mask Qualitative Assessment Tool (MQAT).

Background: Respiratory masks can provide healthcare workers with protection from biological hazards when they have good performance. There is a direct relationship between the visual specifications of a mask and its efficacy; thus, the aim of this study was to develop tools for qualitative assessment of the performance of masks used by healthcare workers. Methods: A mixed-methods design was used to develop a qualitative assessment tool for medical face masks (MFM) and particle filtering half masks (PFHM). The development of domains and items was undertaken using observation and interviews, the opinions of an expert panel, and a review of texts and international standards. The second phase evaluated the psychometric properties of tools. Finally, the validated Mask Qualitative Assessment Tools (MQAT) were used to assess six samples from 10 brands of the two types of masks. Results: MQAT-MFM and MQAT-PHFM shared 42 items across seven domains: "cleanliness," "design," "marking, labeling and packaging," "mask layers," "mask strap," "materials and construction," and "nose clip." MQAT-MFM included one additional item. MQAT-PHFM included another nine items associated with an eighth "Practical Performance" domain, and the valve version had another additional "Exhalation Valve" domain and six items. The evaluation indicated 80% compliance for MFM and 71% compliance for PFHM. "Marking, labeling and packaging" and "Layers" were associated with the least compliance in both types of masks and should be checked carefully for defining mask quality. Conclusion: MQAT can be used for immediate screening and initial assessment of MFM and PHFM through appearance, simple tools, and visual inspection.

Alleviating work-family conflict for female employees in Iran: The effect of a multimedia educational intervention.

Work-family conflict can lead to irreparable losses to individuals, families and organizations. This matter is especially important for married working women who cannot eschew home responsibilities. To consider an appropriate intervention for this issue, we investigated the effect of a one-month intervention on support from the workplace and the family, individual characteristics and work-family conflict. This quasi-experimental longitudinal study includes an intervention group and a control group, and uses a pre-test, post-test and 6-months follow up design. Participants were 120 married women working in healthcare services, recruited from two cities in South Iran. The web-based multimedia educational program comprised four modules: one for each of the women participants, their spouses, their co-workers, and their workplace supervisors. Data collection tools included a demographic information form, and co-worker support, supervisor social support, spouse support, core self-evaluation and work-family conflict questionnaires. The effect of the intervention was examined at two post-intervention time points. A comparison of changes in mean scores between the intervention and control groups indicated that scores of supervisor support, spouse support, core self-evaluation and work-family conflict in the intervention group one month and six months after the intervention were all significantly improved compared to before the intervention. There was no benefit of the intervention in terms of a change in co-worker support. There was no significant difference across the three time points in the control group. These results confirm that online educational methods can enable health promotion professionals to reduce work-family conflict to the benefit of both employees and organizations.

Effects of an ergonomic intervention program based on the PRECEDE-PROCEED model for reducing work-related health problems and exposure risks among emergency medical dispatchers.

OBJECTIVE: To evaluate the effectiveness of an ergonomic intervention program based on the PRECEDE-PROCEED model in terms of improving exposure risks and work-related health problems in emergency medical dispatchers. METHODS: This quasi-experimental study used an interrupted time series design. Participants were 55 employees working in an Emergency Medical Communications Center in Iran. The intervention program was based on the PRECEDE-PROCEED model and included five face-to-face training sessions and installing auxiliary equipment according to best ergonomic principles. Direct observations of the emergency medical dispatchers' working postures using the Rapid Office Strain Assessment and a survey which included a modified Nordic Questionnaire, Work Ability Score, Visual Fatigue Questionnaire, and a Behavioral Factors Questionnaire were used at three time points: baseline, 1 month post-intervention, and 3 months post-intervention. RESULTS: The modified Nordic Questionnaire showed significant reductions in pain intensity scores for neck, lower back, knee and ankle after the ergonomic intervention program. In addition, there were considerable post-training improvements in behavioral factors (knowledge and enabling factors) and working postures. No significant changes were observed in Work Ability Scores, or visual symptoms. CONCLUSIONS: An ergonomic intervention program based on a systematic framework such as the PRECEDE-PROCEED model and on-site interventions can be effective in improving and enhancing the working conditions of emergency medical dispatchers. Therefore, it is suggested that ergonomic interventions be implemented based on standard and valid behavioral change models such as PRECEDE-PROCEED model in other work environments in which musculoskeletal pain and digital eye strain are common.

Assessing the ergonomic status of commonly used chairs in Iran's universities based on combinational equations and anthropometric indices.

BACKGROUND: Inappropriate design of chairs and disproportion with students' body dimensions can influence their physical and mental health as well as their educational efficiency and concentration. OBJECTIVE: The aim of this study was to examine the ergonomic status of commonly used chairs in Iran's universities using combinational equations and anthropometric indices. METHODS: Participants in this cross-sectional study were 166 students in Iran. Eleven anthropometric parameters of the students and nine dimensions in seven types of commonly used chairs in Iran's universities were measured. Combinational equations were used to determine the fitness of the chairs. RESULTS: There was a major mismatch between most students' anthropometric measurements and the dimensions of the chairs. Backrest height and seat height were the best and the worst features, respectively, according to ergonomic recommendations for chairs. The recommended measurements of seat height, seat depth, seat width, desk height, desk width, desk length, backrest width, backrest height, and desk distance were 332, 420, 436, 245, 95, 511, 426, 550, and 281 mm, respectively. CONCLUSION: None of the commonly used chairs in Iran's universities were found to be a good fit to the students' anthropometric dimensions. Therefore, in order to prevent inappropriate body postures, chair designs have to reviewed, and made to fit with Iranian students' anthropometric data. The recommended measurements obtained in this study can be used to design a suitable ergonomic chair to match with a high percentage of Iranian students.

Understanding quality of life across different clinical subtypes of multiple sclerosis: a thematic analysis.

PURPOSE: Multiple sclerosis (MS) is a neurological disease that has different clinical presentations and illness trajectories. The aim of this study was to explore factors that are important for quality of life (QoL) of people with MS (pwMS), and to understand how they may differ across three subtypes. METHODS: Both convenience and purposive sampling were employed. Semi-structured interviews were conducted with people with relapsing-remitting MS (n = 16), secondary progressive MS (n = 14), and primary progressive MS (n = 13). All interviews were audio recorded and then transcribed verbatim for thematic analysis involving both inductive and deductive processes. A separate analysis for each subtype was made during the inductive process before examining for similarities and differences across the three subtypes in the deductive process. FINDINGS: Four factors were identified to have an important influence on QoL of pwMS: restricted and disrupted enjoyment, disturbed future, challenged sense of self, and well-being of significant others. The themes reflect how pwMS commonly perceived enjoyment as a purpose of life, while also illustrating how their QoL may be questioned because of new perspectives going forward with MS, challenges to their sense of self, and increased concerns for their significant others as a result of MS. Subtype differences were attributed to different illness trajectories: relapsing or progressive. CONCLUSIONS: There are subtype differences in the negative impact of MS on QoL. Clinicians are encouraged to understand the challenges of different illness trajectories, in particular the traumatic nature of relapses and steady worsening of symptoms among those with progressive subtypes of MS.

Structural equation modeling of safety performance based on personality traits, job and organizational-related factors.

Purpose. This study investigated the relationship between three selected personality traits and contextual factors with safety performance. Methods. This cross-sectional study was carried out among the operational staff of a gas refinery (n = 487) in Iran. Structural equation modeling was used to model the factors affecting safety performance based on personality traits and job and organizational-related factors including consideration of future safety consequence, safety locus of control and impulsiveness, safety climate, job insecurity and role overload, and mediator roles of safety knowledge and safety motivation. Results. Structural equation modeling results indicated that consideration of future safety consequence was directly correlated with safety performance. Impulsiveness and safety locus of control were indirectly associated with safety performance through the mediator role of safety knowledge and motivation. Furthermore, job insecurity and role overload were partially and directly correlated with safety performance. Moreover, safety climate had a significant relationship with safety performance. Conclusion. Consideration of future safety consequence is a valid personality trait for predicting safety performance. It can therefore be used as an indicator in the employee selection process. Moreover, improving employee safety performance necessitates increased safety knowledge and motivation as well as improved occupational characteristics and safety climate.

Flexibility to manage and enhance quality of life among people with motor neurone disease.

OBJECTIVES: To identify influential factors for quality of life (QoL) among individuals with motor neurone disease (MND) and explore how regulatory flexibility and psychological flexibility may contribute towards maintaining and improving QoL. METHODS: Semi-structured interviews were conducted with 26 individuals with MND. Thematic analysis, using both inductive and deductive analyses, was employed to examine subjective QoL in view of previous understanding of QoL. RESULTS: Four factors were important for the QoL of participants: perceived illness prognosis, sense of self, concerns for significant others, and life to enjoy. These factors reflected psychological stress caused by MND, the participant's value system, and their beliefs about life. In optimising QoL, both regulatory flexibility and psychological flexibility were essential to maintain and enhance QoL. Often, regulatory flexibility was perceived among those employing a mindful approach, and psychological flexibility was found to involve savouring positive experiences. CONCLUSIONS: People with MND reported that seeking ways to both maintain and enhance their QoL is crucial, and that this may be accomplished by increasing flexibility through mindfulness and savouring. (171/200 words)Implications for rehabilitationPeople with motor neurone disease (MND) seek to maintain quality of life (QoL) following changes caused by the condition, whilst attempting to enhance QoL by maximising their positive experiences.Regulatory flexibility is essential to maintain QoL and it was closely associated with mindful approach so that MND is not perceived as an inevitable threat to QoL.Psychological flexibility was found to enhance QoL and it involves savouring positive experiences, while abandoning fault-finding of the current situation.Positive inter-personal interactions can encourage people with MND to engage with mindfulness and savouring for favourable outcomes in terms of QoL; current support services should orient towards both mindfulness and savouring.

Comparison of the work ability index and the work ability score for predicting health-related quality of life.

PURPOSE: To compare the relationship of the 7-item Work Ability Index (WAI) and the single-item Work Ability Score (WAS) with individual and work-related factors, and to investigate the predictive role of these two work ability assessments for health-related quality of life (HRQOL). METHODS: This is a cross-sectional study. 407 of 445 employees working on a construction project in Shiraz, Iran consented to participate in an anonymous survey. 381 surveys were returned completed. Correlation analyses were used to evaluate relationships between WAI and WAS, and the total score and four domains of the WHOQOL-BREF, our measure of HRQOL, and individual and work-related variables. Hierarchical multivariate linear regression analyses were performed to compare WAI and WAS in predicting HRQOL and its four dimensions. RESULTS: WAI and WAS were both significant predictors of HRQOL and its four dimensions and the explained variance was very similar. The WAI and WAS explained 46% and 44% of the variance related to the HRQOL, respectively. WAI and WAS explained 36-38% and 35-37% of the variance related to dimensions of the HRQOL, respectively. There were significant relationships of both WAS and WAI with job type, work schedule, smoking, and exercise habit. CONCLUSIONS: The WAS and WAI showed a very similar relationship with participants' individual and work-related factors and HRQOL. The Work Ability Score is a valid and suitable measure for assessment of work ability among Iranian workers. Use of this simple measure could be advantageous to reduce demands on research participants and in workability assessments.

Understanding uptake of prevention and mitigation of COVID-19 at work actions in Iran.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has required organizations to make changes to ways of working to prevent and mitigate COVID-19 in employees. OBJECTIVE: To assess the workplace response to COVID-19 in Iran. METHODS: 255 organizations completed a two-part survey. Part 1 collected data describing the business; part 2 comprised the International Labor Organization (ILO) 30-item Prevention and Mitigation of COVID-19 at Work Actions Checklist. A four-point Likert scale was used to score each item according to whether preventative measures had been actioned. RESULTS: We found a dichotomy of commitment to managing COVID-19 at work. 42.5%of organizations had fully implemented the ILO recommended preventative actions, and 45.6%workplaces had not implemented any. Large organizations had significantly more preventative actions than SMEs; the healthcare sector had significantly better COVID-19 mitigation measures in place than construction projects; and organizations with a health and safety management system had significantly more prevention actions in place. CONCLUSIONS: ILO provided a good framework to support risk assessment of COVID-19, however only half the organizations were undertaking the necessary biological hazard control actions to prevent COVID-19 at work. There remains a need to understand the inaction of organizations who do not risk assess despite being in a pandemic.

Presenteeism and work ability: development of the Persian version of the Stanford Presenteeism Scale (P-SPS-6) and measurement of its psychometric properties.

BACKGROUND: Presenteeism is recognized in Iran's hospitals, however little research has been done to understand and tackle the phenomenon because of a lack of valid tools to measure presenteeism. This study aimed to develop a Persian version of the Stanford Presenteeism Scale (SPS-6) and measure its psychometric properties. Another goal was to examine the relationship between presenteeism and work ability using a sample of 250 nurses. METHODS: The forward-backward translation process and cross-cultural adaptation of the scale were performed according to a standard method. The psychometric properties of the scale were measured using face and content validity, construct validity based on confirmatory factor analysis (CFA), and internal consistency. Work ability score (WAS) was used to assess discriminative validity and examine the relationship between presenteeism and work ability. Measures of Job Satisfaction and Emotional Exhaustion were used to assess convergent validity with the developed presenteeism scale. RESULTS: Mean content validity index and content validity ratio were 1 and 0.93 respectively. CFA verified the two-dimensional structure of the scale. Cronbach's alpha was 0.77. There were positive relationships between P-SPS-6 and Job Satisfaction, and P-SPS-6 and WAS. There was a significant negative relationship between P-SPS-6 and Emotional Exhaustion. CONCLUSION: Our findings suggested that the P-SPS-6 had appropriate psychometric properties for studying presenteeism in employees using the Persian language. Given the negative relationship between presenteeism and work ability and the negative consequences associated with it, it is necessary to regularly evaluate this stressor and to emphasize purposeful intervention programs to control or reduce it.

Study protocol for a randomized controlled trial to improve the quality of life of housewives with musculoskeletal disorders: a health promotion intervention based on a participatory ergonomic approach-the Housewives Ergonomic Intervention (HEI) trial.

BACKGROUND: A variety of household chores expose women to a variety of biomechanical and psychosocial risk factors. A result of this is many housewives with musculoskeletal disorders. Given the interactive effects of these risk factors, it is necessary to consider multiple strategies to mitigate their effects. Accordingly, the present study will investigate the impact of a health promotion training program based on a participatory ergonomic approach towards a reduction in the prevalence of musculoskeletal disorders and an improvement in the quality of life of housewives. METHODS: Iranian housewives aged 20-65 years currently attending a specialist health clinic due to a painful musculoskeletal complaint will be invited to join the study. Recruitment will continue until a sample of 160 women provides informed consent to participate. The study will be conducted using a mixed-methods protocol in two phases. In the first phase, psychosocial and biomechanical risk factors will be identified using a qualitative approach. In the next phase, the results from the qualitative approach will be used to develop a conceptual framework based on health promotion theories and an intervention program based on a participatory ergonomic approach designed. Participants will be randomly allocated into one of four groups: (1) biomechanical intervention group, (2) psychosocial intervention group, (3) multidisciplinary intervention group (both biomechanical and psychosocial intervention), and (4) a control group. Data will be collected using Rapid Entire Body Assessment (REBA), Visual Analog Scale (VAS), Work Ability Score (WAS), Hospital Anxiety and Depression Scale (HADS), and the 36-item Short-Form health survey (SF-36) at baseline in 3-month and 6-month follow-up assessments. The impact of the three interventions on musculoskeletal disorders, work ability, stress, and quality of life will then be evaluated. DISCUSSION: The study will provide a practical approach to reducing stress, reducing musculoskeletal disorders, enhancing the ability to work, and improving the quality of life of women with musculoskeletal disorders associated with housework. If the designed interventions in the present study are effective, they will have the great practical potential for generalization to all housewives.

Development and validation of a Nurse Station Ergonomics Assessment (NSEA) tool.

BACKGROUND: Nurse stations are one of the primary units for supporting effective functioning of any hospital. They are important working environments that demand adherence to known ergonomic principles for the well-being of both staff and patients. The aim of this study was to develop a psychometrically tested tool for the assessment of the ergonomic conditions of nurse workstations in hospitals. METHODS: Ten hospitals, with a total of 133 nurse stations participated in this mixed-methods research. The domains and items of the tool were developed based on a literature review, an experts' panel, and interviews with nurses. RESULTS: The final nurse station ergonomic assessment (NSEA) tool has good psychometric properties. Validity was assessed by face validity and content validity. Reliability was evaluated using inter-rater agreement and test-retest reliability analyses with a four-week interval between assessments. The NSEA is comprised of 64 items across eight domains: layout and location (7 items), workspace (11 items), security-safety (5 items), environmental conditions (8 items), counter (8 items), chair (13 items), desk (9 items), and monitor (3 items). CONCLUSIONS: The NSEA adds to the literature a tool for managers to ensure they comply with legal requirements and support best practice for those working on hospital wards. The NSEA can be used to identify challenges for healthcare professionals who use nurse stations and support the execution of targeted interventions to improve human-environment interactions.
