The effect of a social cognitive theory-based educational intervention on nonsuicidal self-injury prevention in high school students: A randomized educational intervention trial.

INTRODUCTION: Nonsuicidal self-injury (NSSI) in adolescents is a growing public health concern, demanding preventive measures, particularly among high school students. Based on social cognitive theory (SCT), self-efficacy coupled with outcome expectations, social support, self-regulation, and behavioral intention, determine the likelihood of engaging in such a behavior. Thus, the present study was to investigate the effect of a SCT-based educational intervention on NSSI prevention in female high school students. METHODS: This randomized educational intervention trial was conducted on 191 female high school students, aged 15-17 years (15.95 ± 0.59) (viz. 99 individuals in intervention group and 92 controls). Intervention group attended five SCT-based educational intervention sessions concerning NSSI prevention. Data were then collected by three self-administered questionnaires. The first questionnaire was to measure demographic variables and the second one, intermediate outcome measure, was implemented to evaluate SCT constructs. The third questionnaire also measured NSSI (final outcome measure). Data were analyzed using SPSS software v.24. RESULTS: After controlling the pretest scores, the repeated-measure multivariate analysis of covariance revealed a significant time and group interaction in multivariate (F = 154.8, p < .001) and univariate analysis, which is in favor of the effectiveness of educational intervention on changing the mean scores of NSSI and all SCT constructs. SCT constructs explained 41% of the variance in conforming intention for NSSI prevention (p < .001). CONCLUSION: The study findings were in favor of effectiveness of an SCT-based educational intervention in intention of preventing NSSI.

Environmental Engineering Applications of Electronic Nose Systems Based on MOX Gas Sensors.

Nowadays, the electronic nose (e-nose) has gained a huge amount of attention due to its ability to detect and differentiate mixtures of various gases and odors using a limited number of sensors. Its applications in the environmental fields include analysis of the parameters for environmental control, process control, and confirming the efficiency of the odor-control systems. The e-nose has been developed by mimicking the olfactory system of mammals. This paper investigates e-noses and their sensors for the detection of environmental contaminants. Among different types of gas chemical sensors, metal oxide semiconductor sensors (MOXs) can be used for the detection of volatile compounds in air at ppm and sub-ppm levels. In this regard, the advantages and disadvantages of MOX sensors and the solutions to solve the problems arising upon these sensors' applications are addressed, and the research works in the field of environmental contamination monitoring are overviewed. These studies have revealed the suitability of e-noses for most of the reported applications, especially when the tools were specifically developed for that application, e.g., in the facilities of water and wastewater management systems. As a general rule, the literature review discusses the aspects related to various applications as well as the development of effective solutions. However, the main limitation in the expansion of the use of e-noses as an environmental monitoring tool is their complexity and lack of specific standards, which can be corrected through appropriate data processing methods applications.

Non-cognitive factors associated with driving cessation among older adults: An integrative review.

Exploring the factors that affect driving cessation is crucial, because sustained mobility plays an important role in successful aging. This study aimed to collect evidence on the non-cognitive factors associated with driving cessation among older adults. The method used in this study was an integrated review of published research on the factors affecting driving cessation. A comprehensive search was performed using electronic databases including PubMed, Web of Science, Scopus, CINHAL, ProQuest, EBSCO, and Google Scholar. The results revealed six main categories (physical health, psychological health, interpersonal influence, transportation support, policies, and sociodemographic characteristics) and 24 subcategories for driving cessation. Given the potentially serious consequences of driving cessation in the older adult population, exploring the predictors of driving cessation can be used to design interventions for optimizing drivers' health, rehabilitating the functional limitations that affect driving ability, creating a safer driving environment, and optimizing vehicles to meet the needs of older drivers.

Psychometric Properties of the CAGE Questionnaire Amongst Middle-Aged and Older Adults in Khuzistan Province of Iran.

The CAGE questionnaire is an instrument, proved useful in helping to make a diagnosis of alcoholism. The questions focus on Cutting down, Annoyance by criticism, Guilty feeling, and Eye-openers. The questionnaire has been more pervasive simple tool than AUDIT and LAST scales to screen in busy medical settings where limited time is considered for adult patient interviews. The present study aimed to determine the reliability and validity of the CAGE questionnaire in Khuzistan province, Iran and evaluate its role in detecting alcohol-related problems. For this purpose, 382 men with mean age of 65 ± 5 were sampled by cluster-random sampling method in convenience model from the medical centers in eight counties of Khuzistan province during 2019 and they responded to the CAGE questionnaire. The coefficients of Cronbach's alpha (α = 0.82), convergent validity (0.73), divergent validity (-0.06), and criterion validity (0.87) were estimated (ρ < 0.01). The exploratory factor analysis demonstrated that the four -items related to the CAGE for the aged samples are organized into one factor, which clarifies 94% of the variance. Based on the results of the second-order confirmatory factor analysis, all factors were matched up well into a principal factor. Finally, the one -factor model was appropriate for the data by using the fit index techniques for adjusting the scale (AGFI = 0.81, TLI = 0.91, GFI = 0.93, RMSEA = 0.006, IFI = 0.94, NFI = 0.91, CFI = 0.97).The results could prove the well-adjusted reliability and validity of the CAGE and its usefulness for the relevant studies.

Effectiveness of resilience training intervention on psychological capital of the underprivileged widowed women of Fasa City, Iran.

INTRODUCTION: Women heads of households (widows or divorcees) are vulnerable groups in society who face various psychological problems and have less resilience than other women. Therefore, the present study was conducted to determine the effectiveness of resilience educational intervention on the psychological capital of poor widows in Fasa city, south Iran. MATERIALS AND METHODS: In this quasi-experimental study, 120 widows covered by Imam Khomeini Relief Foundation were selected by a simple random sampling method based on a random Efron algorithm (Efron coin) and randomly assigned into two interventions and control groups (60 people each) in the second half of 2021. About 8 training sessions on resilience and psychological capital were held for the experimental group through training clips, audio transmissions, and podcasts. Data were collected using demographic characteristics forms, widowers' resilience assessment questionnaires, and Luten's psychological capital scale for testing and control before and two months after the intervention. Data were analyzed with Chi-square test, independent and paired t-test using SPSS V. 26 software. RESULTS: There were differences between the two groups at pretest in demographic variables and psychological capital and its subscales, and resilience and its subscales (P ≥ 0.05).. But two months after the educational intervention, a statistically significant increase was observed in the experimental group in these variables compared to the control group (p < 0.05). It indicates that there was an improvement in the outcomes from pretest to post-test within the intervention and no change in the outcomes over time within the control group. DISCUSSION AND CONCLUSION: Using a resilience-based educational approach as a novelty of this research to promote psychological capital and resilience can increase resilience and psychological capital in widows. Then, considering the positive effect of this educational approach and the low cost of this intervention, it seems that the implementation of such interventions should be included in the plans related to widows.

Effects of a theory-based training program with follow-up home visits on self-management behavior, glycemic index, and quality of life among Iranian patients with type 2 diabetes mellitus.

BACKGROUND: Uncontrolled diabetes is an important public health problem that endangers the quality of life of patients. Promoting self-management through well-planned training is an essential strategy to control diabetes effectively. This study aimed to examine the effects of a training program based on social cognitive theory (SCT) on self-management behavior, glycemic index, and quality of life among patients with type 2 diabetes mellitus. METHODS: This is a quasi-experimental study with a pretest-posttest design. The statistical population included 106 adults with type 2 diabetes mellitus assigned to the intervention and control groups [n1 = n2 = 53], who received services from two urban health centers. A multi-method, SCT-based training program consisting of six 60-80-min sessions was run, followed by 2-3 follow-up home visits [once a month for each participant] for the intervention group. The data were collected before and three months after the intervention and were analyzed in SPSS 19. RESULTS: Before the intervention, there was no significant difference between the two groups regarding the main variables. After the intervention, there was a significant increase in the intervention group's mean scores of knowledge, self-efficacy, social support, outcome expectations, self-regulation, self-management behavior, glycemic index, and quality of life. There were no significant changes in these constructs in the control group after the intervention. The regression analysis results indicated that social cognitive theory and self-management could explain the variance in quality of life [adjusted R-squared = 0.476]. CONCLUSIONS: The findings support the effectiveness of the multi-method, SCT-based educational intervention in improving self-management behaviors, glycemic index, and quality of life among patients with type 2 diabetes mellitus. It is suggested that the quality of type 2 diabetes care programs should be promoted. However, further research is needed to evaluate the long-term outcomes.

Effect of Thermal and Non-Thermal Technologies on Kinetics and the Main Quality Parameters of Red Bell Pepper Dried with Convective and Microwave-Convective Methods.

The drying process preserves the surplus of perishable food. However, to obtain a good-quality final product, different pretreatments are conducted before drying. Thus, the aim of the study was the evaluation of the effect of thermal (blanching treatments with hot water) and non-thermal technologies (pulsed electric field (PEF) and ultrasound (US)) on the kinetics of the drying process of red bell pepper. The convective and microwave-convective drying were compared based on quality parameters, such as physical (water activity, porosity, rehydration rate, and color) and chemical properties (total phenolic content, total carotenoids content, antioxidant activity, and total sugars content). The results showed that all of the investigated methods reduced drying time. However, the most effective was blanching, followed by PEF and US treatment, regardless of the drying technique. Non-thermal methods allowed for better preservation of bioactive compounds, such as vitamin C in the range of 8.2% to 22.5% or total carotenoid content in the range of 0.4% to 48%, in comparison to untreated dried material. Moreover, PEF-treated red bell peppers exhibited superior antioxidant activity (higher of about 15.2-30.8%) when compared to untreated dried samples, whereas sonication decreased the free radical scavenging potential by ca. 10%. In most cases, the pretreatment influenced the physical properties, such as porosity, color, or rehydration properties. Samples subjected to PEF and US treatment and dried by using a microwave-assisted method exhibited a significantly higher porosity of 2-4 folds in comparison to untreated material; this result was also confirmed by visual inspection of microtomography scans. Among tested methods, blanched samples had the most similar optical properties to untreated materials; however non-thermally treated bell peppers exhibited the highest saturation of the color.

Internet Addiction Effect on Quality of Life: A Systematic Review and Meta-Analysis.

PURPOSE: Due to the use of different methodologies, tools, and measurements, the positive or negative impact of Internet use on human life quality is accompanied by a series of ambiguities and uncertainties. Therefore, in this study, a systematic review and meta-analysis are conducted regarding the effect of Internet addiction on the quality of life. METHODS: A systematic search of resources was conducted to investigate the effect of Internet addiction on the quality of life. The databases of PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Science Direct were searched from January 1980 to July 2020. The articles were screened by two researchers in multiple levels in terms of the title, abstract, and full-text; then, final studies that met the inclusion criteria were retrieved and included in the study. RESULTS: After searching the previously mentioned international databases, 3863 papers were found, 18 of which we included in the final analysis. Surveys indicated that people who had a high Internet addiction received lower scores of quality of life than those who were normal Internet users (OR = 2.45, 95% CI; 2.31-2.61, p < 0.001; I 2 = 85.23%, p < 0.001). Furthermore, There was a negative significant relationship between Internet addiction and quality of life in the psychological (OR = 0.56, 95% CI: 0.32-0.99, p=0.04, I 2 = 97.47%, p < 0.001), physical (OR = 0.58, 95% CI: 0.39-0.86, p=0.007, I 2 = 95.29%, p=0.001), and overall quality of life score (OR = 0.39, 95% CI: 0.27-0.55, p < 0.001, I 2 = 0.0%, p=0.746). CONCLUSION: These findings illustrate that Internet addiction should be regarded as a major health concern and incorporated into health education and intervention initiatives.

The Quality of Infrared Rotary Dried Terebinth (Pistacia atlantica L.)-Optimization and Prediction Approach Using Response Surface Methodology.

Most agricultural products are harvested with a moisture content that is not suitable for storage. Therefore, the products are subjected to a drying process to prevent spoilage. This study evaluates an infrared rotary dryer (IRRD) with three levels of infrared power (250, 500, and 750 W) and three levels of rotation speed (5, 10, and 15 rpm) to dry terebinth. Response surface methodology (RSM) was used to illustrate and optimize the interaction between the independent variables (infrared power and rotation speed) and the response variables (drying time, moisture diffusivity, shrinkage, color change, rehydration rate, total phenolic content, and antioxidant activity). As infrared power and rotation speed increased, drying time, rehydration rate, antioxidant activity, and total phenolic content decreased, while the other parameters were increased. According to the results, the optimum drying conditions of terebinth were determined in the IRRD at an infrared power of 250 W and drum rotation speed of 5 rpm. The optimum values of the response variables were 49.5 min for drying time, 8.27 × 10-9 m2/s for effective moisture diffusivity, 2.26 for lightness, 21.60 for total color changes, 34.75% for shrinkage, 2.4 for rehydration rate, 124.76 mg GAE/g d.m. for total phenolic content and 81% for antioxidant activity.

The Effectiveness of Interventions in Improving Hand Hygiene Compliance: A Meta-Analysis and Logic Model.

BACKGROUND: Despite the availability of various guidelines, rules, and strategies, hand hygiene adherence rates among healthcare workers are reported significantly lower than expected. The aim of this meta-analysis is to determine the most effective interventions to improve hand hygiene and to develop a logic model based on the characteristics of the most effective interventions. METHODS: A literature search was conducted on PubMed, ProQuest, Web of Knowledge, Scopus, Cochrane Library, and ScienceDirect databases up to December 21, 2019, with no time limit. Randomized clinical trials which had designed interventions to improve hand hygiene were reviewed. Data were extracted independently by two authors. All statistical analyses were performed using Comprehensive Meta-Analysis (CMA) software (version 2.0). A random-effects model was used to estimate odds ratios. RESULTS: Although 14 studies were initially reviewed, only 12 studies entered the meta-analysis, since they had identified percentage rates of hand hygiene compliance. The most effective intervention (odds ratio 18.4, 95% CI (13.6-24.8)) was a multilevel strategy that influenced the determinants of hand hygiene behavior at individual, interpersonal, and organizational levels. Following this, a theory-driven logic model was mapped out to promote hand hygiene, based on situational analysis. CONCLUSION: This study suggests that designing integrated interventions based on a multilevel socioecological approach has the greatest potential to improve hand hygiene compliance in healthcare workers. The logical model proposed in this study can thus provide a useful guide for designing and conducting future experimental research.

Improving diet quality among adolescents, using health belief model in a collaborative learning context: a randomized field trial study.

This study aimed to assess the impact of educational intervention, based on health belief model (HBM) and collaborative learning techniques on diet quality in adolescents. In this field trial study, 311 students aged 13-15 years old were included, of which 163 and 148 allocated in the experimental and comparison groups, respectively. They were selected through a stratified random sampling from 16 urban, secondary schools in 4 educational districts of Shiraz, the largest city in southern Iran. The revised children diet quality index was used to assess their diet quality. Using HBM as a framework for targeting determinants of dietary behavior, the intervention was performed in a collaborative learning context during the educational year (2015-16). Constructs of HBM and diet quality were measured before and after the intervention. All HBM's constructs and knowledge had significantly improved in the experimental group and mean differences were increased after the intervention. Diet quality improved in the experimental group (P < 0.001), which was significantly different from the comparison group (P = 0.001). The findings support the integration of appropriate models/theories into the context of collaborative learning methods to target large number of behavioral determinants, and ultimately increase the effectiveness of the educational interventions amongst adolescents.

Modeling of eutrophication and strategies for improvement of water quality in reservoirs.

The purpose of this study is to survey the thermal regime and eutrophication states in Ilam reservoir in Iran as the case study. For this purpose and to find solutions for improving the water's quality in the reservoir, two general strategies for reducing the entering pollution loads and water depletions from the reservoir's outlets were analyzed by use of the CE-QUAL-W2 model. Results of the simulation of the present situation show the existence of thermal stratification during summer, which results in the qualitative stratification in the reservoir. According to the qualitative criteria, the Ilam reservoir's state is between mesotrophic and eutrophic. Results of the scenarios of reduction of the nutrients show that in the scenario of 50% reduction of the phosphorus and nitrogen loads into the reservoir, the state of the reservoir would recover from eutrophic to semi-eutrophic. Also, release of water from the reservoir during September, October and November would cause the restoration of the quality of water in the reservoir. To avoid the occurrence of critical eutrophication in the reservoir, reducing the ponding time in the reservoir by fast depletion, preventing entrance of the upstream villages' sewage and agricultural drained waters, which are sources of nitrate and phosphate contamination into the rivers, and also management of the usage of agricultural fertilizers have been suggested.

Validation of Perceived Wellness Survey (PWS) in a Sample of Iranian Population.

The individual's perception of health, when health is understood to include many dimensions of life, is considered the basis for any improvement in health status. Therefore, the present study aimed to assess the reliability and validity of the Persian version of the Perceived Wellness Scale (PWS) by applying it to employees of the Shiraz University of Medical Sciences. This cross-sectional study was conducted with 180 staff members of the university selected by convenience sampling. The study instrument was a Persian version of the PWS prepared through a translation and back-translation process. The reliability and validity of the instrument were assessed by using confirmatory factor analysis (CFA) and Cronbach's alpha coefficient. A total of 180 employees participated in the study. The mean age of the participants was 32.29 years (SD = 7.39) and 78.1% of the participants were women. The results showed that the Persian version of the PWS is acceptable. Cronbach's alpha coefficient was 0.87 for the whole scale, ranging from 0.68 to 0.85 on different dimensions of the scale. The results of split-half reliability and CFA indicated that the reliability and validity of the PWS are acceptable. The PWS is therefore an effective tool for evaluating the different dimensions of perceived wellness in the Iranian population.

Social support as a coping resource for psychosocial conditions in postpartum period: a systematic review and logic framework.

PURPOSE: This review seeks to examine the current state of postpartum social support and psychosocial conditions among women around the world, as well as explore the relationship between these factors. Additionally, it aims to propose a logical framework for enhancing postpartum social support and psychosocial conditions in this population. METHODS: Following the development of a search strategy, two databases, PubMed and Science Direct, were searched for studies published between January 2019 and May 2023. The search was conducted throughout the entire month of May 2023. The risk of bias in the included cross-sectional studies was assessed using the Newcastle-Ottawa Quality Assessment Scale, which was adapted for this specific study design. To determine if the main objective of the cross-sectional studies was to investigate the relationship between social support and postpartum psychosocial conditions, a review was conducted based on the AMSTAR checklist, PRISMA checklist and PRISMA flow diagram. Data extraction was performed with the consensus of two authors, and a narrative synthesis approach was chosen for data synthesis, following the guidelines provided by the Centre for Reviews and Dissemination (CRD). RESULTS: Eleven cross-sectional studies were included in the final analysis. Our findings revealed that all reviewed studies provided evidence of a positive association between social support and healthy psychosocial conditions in postpartum period. However, due to the absence of standardized measurement indicators to identify and compare the outcomes of various studies, there was a need to develop a conceptual framework that could enhance our understanding of the postpartum psychosocial condition including anxiety, depression, unfavorable quality of life and social support status up to 24 month after child birth. This framework aimed to incorporate childbirth and motherhood as "stressful events," while considering social support as a crucial "coping resource." Furthermore, it acknowledged empowerment, help-seeking behavior, and peer support as important "coping actions," alongside implementing client-centered interventions. Lastly, it recognized postpartum mental health and optimal quality of life as significant "effects" of these factors. CONCLUSIONS: The proposed conceptual framework could define postpartum women's health as "the ability to adapt and self-manage."

Drying kinetic, thermodynamic and quality analyses of infrared drying of truffle slices.

Kinetic and thermodynamic parameters are the most important part for making a suitable tool for drying agricultural products. Moreover, calculation of the energy required for the drying of product, the properties of the rehydration ratio, the food appearance changes, and the evaluation of the microstructure of food are crucial. Since the thermodynamic properties of truffle slices have not yet been reported, this study aims to establish a mathematical model to describe drying process of agriculture product, evaluate the effective moisture diffusion coefficient (Deff), determining the activation energy (Ea) to elucidate the thermodynamic characteristics, measure color characteristics, and rehydration ratio (RR) during the drying process of truffle slices. Truffle slices were dried in an infrared (IR) dryer at four temperatures of 50-80°C and two thicknesses of 0.5 and 1 cm. The best model to describe the drying process of truffle slices was Midilli et al.'s model. The value of Deff, SEC, and RR were in the range of 3.06 × 10-8 to 2.48 × 10-7 m2/s, 79.68-191.271 kWh/kg, and 5.99-7.49, respectively. The Deff of truffle slices increased with the above-mentioned parameters of the samples. The Ea obtained was 26.62-27.43 kJ/mol. The results indicated that enthalpy and entropy decreased with increasing drying temperature, while Gibbs free energy improved. The enthalpy, entropy, and Gibbs free energy values changed between 24.48-25.28 kJ/mol, -130.47 to -122.63 J/mol °K, and 63.97-70.17 kJ/mol, respectively. In addition, the results of color attributes decreased with increasing temperature, while chroma oppositely increased.

Mindfulness and self-regulation intervention for improved self-neglect and self-regulation in diabetic older adults.

The current study aimed to assess the impact of combined interventions including mindfulness and self-regulation on self-neglect and self-regulation among Iranian older adults with type 2 diabetes. This was a three-arm cluster randomized controlled trial study conducted among 135 older diabetic patients in Shiraz, Iran. Three urban healthcare centers (clusters) were randomly assigned to three study groups. The intervention groups received either a Self-Regulation-based Intervention Program (SRIP) or a Combined Mindfulness and Self-Regulation Intervention Program (CMSRIP), while the control group received routine care and COVID-19 prevention training. These training programs, which consisted of text and video-based content, were conducted over 24 weeks using WhatsApp as a mobile-based communication platform. Outcomes were measured using the Elder Self-Neglect Scale and Short-Form Self-Regulation Questionnaire at baseline, week 4, and week 16 post-intervention, with data analysis conducted using SPSS 20 software. The CMSRIP led to significantly greater improvement in the score of self-regulation (χ2 = 73.23, P-Value = < .001) and a reduction in the score of self-neglect (χ2 = 62.97, P-Value = < .001) at both 4 weeks and 16 weeks after education compared to SRIP. In the control group, there was also a slight improvement. Improvement of self-regulation and reduction of self-neglect in all three groups were less in week 16 than in week 4. Nevertheless, the changes in the intervention groups were significantly better than the control group. This study confirmed a combination of mindfulness-based intervention and self-regulation intervention can effectively improve self-neglect and self-regulation behavior in older patients with type 2 diabetes.Trial registration: This trial (ISRCTN77260130) was retrospectively registered on 28/09/2021.

Women's experiences of sexual harassment in the retail clothing industry: a grounded theory study.

Introduction: Sexual harassment is a significant problem in workplaces all over the world. Women's reactions to sexual harassment are influenced by various factors. The aim of the current study was to investigate how women respond sexual harassment in the retail clothing industry. Methods: In-depth face-to-face interviews were conducted with 16 women aged 23-44 years (mean 29.18 years) employed for at least 3 years in clothes shops in Shiraz, Iran. A grounded theory approach was used to analysis the data and raise hypotheses. Results: The main perpetrators of sexual harassment for female saleswomen were male customers. The women experienced conflict-induced stimulation (core phenomenon) when they were faced with sexual harassing behaviors (causal conditions). Such stimulation prompted three types of coping strategies: silence, avoidance, or confrontation. Intervening factors like the characteristics of the Iranian society (including family mores, state-imposed hijab regulations, patriarchal culture, educational system, and regulatory monitoring) and contextual factors (including individual and environmental factors and particularly employer expectations) were found to influence the selection of strategies used as well as their potential consequences in challenging situations. Conclusion: The current study used a grounded theory approach to produce an explanatory storyline that can be tested. Sexual harassment induces conflict-induced stimulation and responses are influenced by intervening conditions, contextual factors, selected strategies, and the perceived consequences of the response. The findings of the grounded theory study suggest that there are negative consequences, particularly in terms of lack of employer support and losing one's job, shame, and family disapproval which act as barriers for female saleswomen to counteracting sexual harassment from male customers. Such an understanding can also be applied to develop educational policies to support women as well as ameliorate the prevalence of this essentially illegal problem.

Predictors of musculoskeletal disorders and job satisfaction among office workers of an oil company: A cross-sectional study in Iran.

BACKGROUND: Musculoskeletal disorders are among the significant causes of disabilities and occupational injuries all over the world and can reduce the quality of life and job satisfaction. These disorders prevail among the office workers of the Iranian Oil Company, though research on the involved factors is limited. OBJECTIVE: The present study investigated the incidence and risk factors of musculoskeletal disorders and their association with job satisfaction among the office workers of the Iranian Oil Company. METHODS: The present research was a cross-sectional descriptive-analytical study on 210 male office workers of the Iranian Oil Company. The prevalence of musculoskeletal disorders and the rate of job satisfaction were measured by Nordic Musculoskeletal and Minnesota job Satisfaction Questionnaires, respectively. The relationship between the variables was analyzed by the SPSS 28 software. RESULTS: The most prevalent musculoskeletal disorders among office workers in the past 12 months were associated with the neck, waist, and knee organs, with 45.70, 41, and 38.10 percentages. Smoking, second jobs, and physical injury histories were identified as three risk factors connected to musculoskeletal disorders (p < 0.05). Forty-one percent of the participants were moderately satisfied with their jobs, and this number was significantly related to musculoskeletal disorders in the shoulders, elbows, back, waist, and knees (p < 0.05). CONCLUSION: The results of this study indicate that second jobs, smoking, and physical injury histories are three risk factors for musculoskeletal disorders among office workers of the Iranian Oil Company. Thus, it is imperative to identify at-risk office workers and train and encourage them to take preventive actions and employ ergonomic job equipment.

Effect of health belief model-based training and social support on the physical activity of overweight middle-aged women: a randomized controlled trial.

Introduction: The highest incidence of overweight among adults is found among women, predominantly middle-aged women. While it has been demonstrated that being overweight increases mortality by compromising physical and mental health, it also imposes substantial costs on the healthcare system. Lack of physical activity is a primary contributing factor to becoming overweight. The majority of inactive adults are women, particularly middle-aged women. Consequently, this study investigated the training program for overweight women based on the health belief model (HBM) and social support approach. Methods: A randomized, controlled trial involving 73 overweight middle-aged women (control group: 37, intervention group: 36) was conducted using simple random sampling. The intervention group participated in six 120-min sessions per week for 6 weeks of a training program based on HBM and social support through physical activity, group discussion, role play, and media. Data were collected using the Physical Activity Questionnaire (IPAQ), Bandura's Exercise Self-Efficacy Scale (Bandura's ESE), and a researcher-made questionnaire before and 4 weeks after the training. The collected data were analyzed using descriptive and inferential statistics via SPSS 27 software. p-values <0.05 were considered statistically significant. Results: A training program based on HBM and social support led to improved perceived benefits (p < 0.001), cues to action (p = 0.03), and self-efficacy (p < 0.001) of physical activity; decreased perceived barriers (p = 0.001); increased social support (p = 0.001); and increased physical activity (p < 0.001). In addition, the BMI of the intervention group decreased after the training program (p = 0.01). Conclusion: The findings of the study demonstrate the efficacy of the training program based on HBM and the social support approach in improving social support and physical activity of women. In addition, the study evaluates the long-term outcome in populations with varying social, economic, and cultural standings.

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.
