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.

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.

Cross-cultural translation and psychometric properties of the Persian version Manchester respiratory activities of daily living questionnaire (MRADLQ-P).

PURPOSE: The present study was an attempt to investigate cross-cultural adaptability and evaluate the psychometric properties of the Persian version of the Manchester respiratory activities of daily living questionnaire ((MRADLQ-P). PATIENTS AND METHODS: In a cross-sectional study, we selected 260 patients with severe respiratory diseases who needed to be admitted to the respiratory wards of this city hospital. The process of cultural localization of the questionnaire was performed based on a standard and valid process. Psychometric properties of the instrument were confirmed based on face and content validity assessments, convergent validity, discriminative validity and internal consistency. Data collected by demographic questionnaire, MRADL questionnaire and work ability index. Data were analyzed by SPSS 22 using descriptive statistics (mean and standard deviation), Spearman correlation coefficient, Cronbach's alpha coefficient, and Mann-Whitney test. RESULTS: The mean age of participants was 48.8 ± 20.1 years. 176 (71.5%) were male. face content validity including content validity index (CVI) was 0.82 and content validity ratio and it was good. The questionnaire was measured at the same time as the work ability index, which Mann-Whitney test showed that the questionnaire has good differential power. Cronbach's alpha coefficient of 0.9 indicates a very good reliability of the questionnaire. CONCLUSION: The results show that intercultural psychometrics of MRADL questionnaire has good validity, reliability, and differential power that can be a good tool for use in future studies. Also, the translation of this checklist included translation into the target language, backward translation of the Persian versions into the original language, and comparisons and ambiguities to obtain a final and acceptable version.

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.

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.

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.

BACKGROUND: Medical gloves play a very important role in protecting health care workers and patients. It is very important to pay attention to the safety and ergonomic properties of medical gloves in their protective function. AIM: To develop a quantitative tool for evaluating the safety and ergonomic properties of the medical gloves. METHODS: Five hospitals with a total of 185 health care workers participated in the research. The domains and items of the tool were developed based on an expert's panel, interviews with health care workers and a literature review. Face, content and construct validity was used for validation. Reliability was also evaluated using internal consistency. RESULTS: The final tool included 26 items in six domains, including tactile sensation, dexterity, grip strength, fitting, reliability and hand hygiene. The Cronbach's alpha was 0.82 for the total scale. CONCLUSION: The final tool had good validity and reliability. The findings of this study led to the development of a comprehensive standard tool that can be used to assess the ergonomic and safety status of medical gloves. IMPLICATIONS FOR NURSING MANAGEMENT: With this tool, problems related to medical gloves can be identified among nurses, and the necessary interventions can be predicted.

Prediction of metabolic syndrome based on sleep and work-related risk factors using an artificial neural network.

BACKGROUND: Metabolic syndrome (MetS) is a major public health concern due to its high prevalence and association with heart disease and diabetes. Artificial neural networks (ANN) are emerging as a reliable means of modelling relationships towards understanding complex illness situations such as MetS. Using ANN, this research sought to clarify predictors of metabolic syndrome (MetS) in a working age population. METHODS: Four hundred sixty-eight employees of an oil refinery in Iran consented to providing anthropometric and biochemical measurements, and survey data pertaining to lifestyle, work-related stressors and sleep variables. National Cholesterol Education Programme Adult Treatment Panel ІІI criteria was used for determining MetS status. The Management Standards Indicator Tool and STOP-BANG questionnaire were used to measure work-related stress and obstructive sleep apnoea respectively. With 17 input variables, multilayer perceptron was used to develop ANNs in 16 rounds of learning. ANNs were compared to logistic regression models using the mean squared error criterion for validation. RESULTS: Sex, age, exercise habit, smoking, high risk of obstructive sleep apnoea, and work-related stressors, particularly Role, all significantly affected the odds of MetS, but shiftworking did not. Prediction accuracy for an ANN using two hidden layers and all available input variables was 89%, compared to 72% for the logistic regression model. Sensitivity was 82.5% for ANN compared to 67.5% for the logistic regression, while specificities were 92.2 and 74% respectively. CONCLUSIONS: Our analyses indicate that ANN models which include psychosocial stressors and sleep variables as well as biomedical and clinical variables perform well in predicting MetS. The findings can be helpful in designing preventative strategies to reduce the cost of healthcare associated with MetS in the workplace.

Development and validation of dust exposure prevention questionnaire for cardiovascular patients based on the health belief model.

BACKGROUND: Many cardiovascular patients suffer from respiratory failure. Environmental conditions can exacerbate symptomatology. It is necessary to prevent exposure to dust by taking educational steps to identify and modify patient behavior. This study aimed to develop and validate a dust exposure behavior questionnaire based on the Health Belief Model. METHODS: A mixture of qualitative and quantitative methods was employed to design and develop the desired tool. Qualitative methods were used to identify the preventive behaviors needed by cardiovascular patients at risk of dust exposure using the opinions of two expert panels and a literature review. The quantitative phase of the research was performed to evaluate the psychometric properties of the research tool. The research population comprised 417 people with cardiovascular disease referred to a heart hospital in Bushehr, Iran in 2018. Consenting participants entered the study through consecutive sampling. RESULTS: The final version of the questionnaire included 27 items across six domains, namely perceived susceptibility, perceived barriers, perceived severity, perceived benefits, cues to action, and self-efficacy. The mean values of the content validity ratio and content validity index were 0.93 and 0.9, respectively. In addition, all items had a good correlation with the total score of their parent domain (P < 0.01). The model fit was initially unsuitable, according to the related indices. Hence, to achieve a better model fit, the model was improved by releasing some parameters based on the modifications suggested by the AMOS software. The modified model featured an acceptable fit (χ2/df = 2.2, P < 0.001). Cronbach's alpha coefficients also confirmed appropriate reliability for all six domains. CONCLUSION: The Dust Exposure Prevention questionnaire has desirable psychometric properties and appropriate validity to determine the behavioral factors involved in harm from dust exposure among cardiovascular disease patients. This marks an effective step toward evaluating the factors effective in preventing complications related to dust exposure among such patients.

Multiple environmental and psychosocial work risk factors and sleep disturbances.

BACKGROUND: This study aimed to investigate the relationship between multiple psychosocial and environmental work risk factors and sleep disturbances. METHODS: This cross-sectional study was conducted among 90 workers in a brick factory in Iran. The health and safety executive (HSE) tool, Epworth Sleepiness Scale (ESS), and Stop-Bang questionnaire were used to determine psychosocial factors, subjective sleepiness, and obstructive sleep apnea (OSA), respectively. Standard objective methods were used to assess the environmental risk factors, including noise, light, heat stress, and respirable particles. RESULTS: Most psychosocial and all environmental work factors were moderately to highly correlated to the ESS score. There were also moderate correlations between the demands (including work load, work patterns, and work environment), role (including a clear understanding of the employees about their role in the organization), and lighting variables and the Stop-Bang score. The results of multivariate logistic regression analysis showed that job control, wet bulb globe temperature (WBGT), and respirable dust were predictive of an ESS score indicating abnormal sleep status and noise was predictive of a Stop-Bang score predictive of OSA. CONCLUSIONS: The results suggest that stressors, especially noise, heat stress, and respirable dust, are related to the employees' indices of sleep disturbance independent of other potential workplace confounding factors. These results can highlight the importance of considering multiple psychosocial and environment work risk factors for implementing occupational health and ergonomics interventional programs to prevent sleep disturbances in the workforce.

Development and validation of the tool for the evaluation of the behavioral factors affecting the prevalence of musculoskeletal disorders in Iranian students.

BACKGROUND: This study was conducted with the aim of developing a standard and valid questionnaire to evaluate the behavioral factors affecting musculoskeletal disorders among adolescent students based on the educational and ecological diagnosis phase of the PRECEDE model. METHODS: Based on the PRECEDE model and by using available resources and a panel of experts, a reservoir of items was proposed. The content validity of the questions was measured using content validity ratio (CVR) and content validity index (CVI). 400 Iranian first-year female high school students completed the questionnaire. The construct validity was assessed using confirmatory factor analysis (CFA). The reliability of the questionnaire was evaluated using Cronbach's alpha coefficient. RESULTS: The age range of study students was 13.69 ± 0.86 years. The final developed questionnaire included 25 items in three dimensions: knowledge (9 items), attitude (10 items) and enabling factors (6 items). The mean scores of CVI and CVR were 0.97 and 0.92, respectively. The results of CFA confirmed the three-factor structure of the questionnaire. The Cronbach's alpha coefficients of the dimensions of knowledge, attitude and enabling factors were 0.65, 0.80 and 0.71, respectively. CONCLUSIONS: The present questionnaire had appropriate psychometric properties and could be used as a valid tool in evaluating the factors affecting the development of musculoskeletal disorders among adolescent students.

Lifestyle and Shiftwork: Designing and Testing a Model for Health Promotion of Iranian Nurses.

BACKGROUND: Lifestyle is one factor that forms the nurses' health, particularly those who work in shiftwork schedules. AIMS: The aim of this study was to design and test a model for health promotion of Iranian nurses. In this model, nurses' lifestyle was considered as the precedent, physical and mental health as the outcomes, and sleep disturbance and chronic fatigue as the mediators. METHODS: A cross-sectional study using structural equation modeling was conducted among 240 shiftworker nurses in Iran. The data collection was performed using the Persian versions of the Survey of Shiftworkers Questionnaire and Life Style Questionnaire. Bootstrap in Preacher and Hayes' Macro program was used for testing mediation. RESULTS: Lifestyle had a weak significant direct effect on physical (ß = 0.13, p < .04) and mental health (ß = 0.12, p < .02), and it had a significant indirect effect on physical health via chronic fatigue (ß = -0.11, p < .001) and sleep disturbance (ß = -0.05, p < .01). This variable only had a significant indirect effect on mental health via chronic fatigue (ß = -0.19, p < .001). The final model proposed a new significant path between sleep disturbances and chronic fatigue (ß = 0.22, p < .001). CONCLUSIONS: Therefore, the hospital officials can enhance the nurses' physical and mental well-being by providing interventions and training courses on aspects of healthy lifestyles, such as physical activity, avoidance of smoking, and maintenance of body weight.

Design and Validation of a Health Literacy Assessment Tool for COVID-19 Among Iranian Workers.

BACKGROUND: The workforce is an organization's most important asset, and ensuring their health and safety is crucial for achieving the organization's mission and goals. OBJECTIVE: The objective of this study was to design and validate a health literacy tool for COVID-19 among Iranian workers. METHODS: This cross-sectional study involved a total of 201 participants. A personal information questionnaire was administered, and The Health Literacy Assessment (HLA) Tool was used to collect data specifically related to COVID-19. The HLA for COVID-19 was designed and developed, and the validity of the tool was evaluated through face, content, convergent, and construct validity analyses. To examine convergent validity, the Perceived Stress Scale was used. The reliability of the questionnaire was assessed using internal consistency measures, such as Cronbach's alpha coefficient. KEY RESULTS: The mean content validity index was 0.93, indicating high content validity. Confirmatory factor analysis results supported the five-dimensional structure of the tool. Significant correlations were found between the HLA for COVID-19 and perceived stress levels. The Cronbach's alpha coefficient for all items was 0.84, indicating high internal consistency. CONCLUSION: The HLA for COVID-19 is a concise, reliable tool for measuring health literacy related to COVID-19 among Iranian workers. Assessing COVID-19 health literacy in this population can be useful in evaluating the effectiveness of government officials, the media, and the medical and scientific community in providing necessary information. [HLRP: Health Literacy Research and Practice. 2024;8(2):e62-e68.].

PLAIN LANGUAGE SUMMARY: The workforce is an organization's most important asset, and ensuring their health and safety is crucial for achieving the organization's mission and goals. The objective of this study was to design and validate a health literacy tool for COVID-19 among Iranian workers.The HLA for COVID-19 is a concise, reliable tool for measuring health literacy related to COVID-19 among Iranian workers. Assessing COVID-19 health literacy in this population can be useful in evaluating the effectiveness of government officials, the media, and the medical and scientific community in providing necessary information. Health literacy plays a crucial role in disease prevention, including the control of epidemics. It can be particularly valuable in empowering societies affected by crises like the COVID-19 pandemic, which has had a profound impact on all aspects of human life. In international studies focused on assessing health literacy during the pandemic, researchers utilized public health literacy scales. However, only one study developed a specific scale to evaluate people's health literacy concerning COVID-19.

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.

Visual ergonomics, performance and the mediating role of eye discomfort: a structural equation modelling approach.

The purpose of this study was to model the visual ergonomic factors affecting performance in human-computer interaction. A cross-sectional study using structural equation modelling was performed with a sample of 200 participants. The measuring instruments included the office lighting survey questionnaire, performance assessment questionnaires, visual ergonomics assessment and an eye discomfort assessment. The hypothetical model evaluated workplace lighting status and visual ergonomics as precursors, performance as the output and eye discomfort as a mediator. The results showed that eye discomfort directly affected performance. Visual ergonomics also had a significant direct effect on eye discomfort. The final model suggested a significant new path between the quality of lighting and visual ergonomics. Also, the quality of lighting had an indirect effect on eye discomfort and performance, and the effect of visual ergonomics on performance was the same. Improving the lighting quality and visual ergonomics can reduce eye discomfort and increase performance.

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.

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.

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.

The role of demographic, job-related and psychological characteristics on the prevalence of repetitive patient safety incidents among Iranian nurses.

BACKGROUND: Job-related psychosocial factors have a substantial effect on the occurrence of adverse events among healthcare professionals. OBJECTIVE: An analytical and descriptive survey was conducted to evaluate the relationship between the occurrence of patient safety incidents and psychological factors. METHODS: The study sample consisted of 177 nurses who were asked about patient safety events over six months. Repetitive patient safety incidents were selected by examining medical records and interviewing specialists. Also, psychological factors were assessed using job content questionnaire (JCQ). RESULTS: Repetitive patient safety incidents were involved medication administration error, pressure ulcer and skin-muscular injuries, patient falls, inability to CPR patients, blood transfusion reactions, and death due to human error. The findings showed that 92 participants (52%) had at least one case of patient safety incident. Among patient safety incidents, medication administration error and death due to human error had the highest and lowest repletion, respectively. Nurses training, job insecurity and peer support were significant predictors of different aspects of patient safety (p < 0.05). CONCLUSION: Proper collaboration between new and experienced nurses can have a significant impact to reduce patient safety incidents. In addition, nursing training can be a good way to understand risk points in medical errors.

Psychometric properties of the Persian version of Proactive-Safety Role Orientation questionnaire (PRO-SAFE).

BACKGROUND: Participation and initiative of workers are effective in promoting safety in the workplace. Proactive-Safety Role Orientation questionnaire (PRO-SAFE) is a proper tool to evaluate the psychological drivers that support the proactive orientation of individuals toward workplace safety. This study was conducted to translate and measure the psychometric properties of the Persian version of PRO-SAFE. METHODS: The PRO-SAFE was translated into Persian using procedures for translation and cross-cultural adaptation. To collect data, 252 employees of a steel complex were selected. To measure the validity of the questionnaire, face, content, convergent, and construct validity was utilized. The questionnaire's reliability was evaluated by assessing its internal consistency. RESULTS: The mean of the content validity index and content validity ratio was equal to 0.83 and 0.85, respectively. We found a positive correlation between PRO-SAFE and safety behavior dimensions (r = 0.372 to 0.792, P < 0.001). Confirmatory factor analysis showed the Persian version of the PRO-SAFE questionnaire had an excellent six-factor model consistent with the original questionnaire. Cronbach's alpha of the Persian version of the PRO-SAFE questionnaire was obtained between 0.717 to 0.880. CONCLUSIONS: The Persian version of the PRO-SAFE questionnaire was found to have appropriate psychometric properties, indicating that it can be confidently used as a valid tool for assessing proactive role orientation toward safety management among Iranian employees.
