A Persian validation of the burnout assessment tool.

BACKGROUND: Burnout is an increasing public health concern. Its prevalence has extended across diverse professions globally, posing significant challenges to individuals, organizations, and society. This phenomenon has undermined employee well-being, productivity, and organizational effectiveness, making it a critical concern in contemporary work environments. The present study aimed to examine the adaptation and assess the validity of the Persian version of the Burnout Assessment Tool (BAT). METHODS: The adaptation process included the translation and back-translation of the BAT. Data were collected on a sample of 580 teachers using the convenience sampling. The BAT-Persian and Utrecht Work Engagement Scale were administered to collect the data. The reliability, factorial structure of the BAT-C and BAT-S, and the convergent and discriminant validity of BAT-C and work engagement were explored. RESULTS: Confirmatory factor analysis supported a four-factor structure for the core dimensions (BAT-C; exhaustion, mental distance, emotional impairment, cognitive impairment), and a two-factor structure for the secondary dimensions (BAT-S; psychological distress, psychosomatic complaints). In the second-order model, the item loadings on the four factors of BAT-C ranged from 0.35 to 0.85, and on two factors of BAT-S ranged from 0.63 to 0.89. The Persian versions of the BAT-C and BAT-S showed good internal consistency (respectively, α = 0.95 and 0.90). Additional evidence supports the convergent and discriminant validity of the BAT-GR. the BAT-C and its scales were negatively correlated with work engagement and dimensions (i.e., vigor, dedication, and absorption). Moreover, the BAT-S and its scales negatively correlated with work engagement and dimensions. CONCLUSIONS: This study provided evidence that the Iranian version of BAT represents a reliable and valid tool for measuring burnout in the work context. A reliable and valid tool for assessing burnout in the Iranian workplace enables early detection of employee distress, allowing for timely intervention and support. This means that identifying the signs and symptoms of burnout in the early stages can prevent more severe consequences such as absenteeism, reduced productivity, or turnover.

Carpal tunnel syndrome severity, hand discomfort, and usability among three types of computer mouse.

BACKGROUND: Numerous people use computer mice for long hours, especially in offices. Mouse users reported various pains and discomfort. OBJECTIVE: The study aimed to assess three types of most common mice (vertical, traditional, flat) in Iran in terms of their effects on carpal tunnel syndrome, hand discomfort, and usability. METHODS: The Boston Carpal Tunnel Syndrome questionnaire, the Cornell Hand Discomfort Questionnaire (CHDQ), System Usability Scale (SUS), and Workplace Ergonomic Risk Assessment (WERA) scores were used to assess vertical, traditional, and flat mice. In addition, the participant's hand position was analyzed by observation method. RESULTS: Most participants had medium carpal tunnel syndrome severity; however, flat mouse users had a higher score, and the difference between mice was insignificant (p > 0.05). Most mouse users felt discomfort in their small and ring fingers, and the type of mouse significantly affected thumb discomfort level. More flat users felt Pain in the different parts of their hands. The flat mouse has the least SUS score. There was a significant difference between the three mice regarding SUS scores (p < 0.05). WERA mean values were acceptable for numerous mice. Adopting neutral wrist postures was more common among vertical, flat, and traditional mouse users, respectively; however, the flat mouse users tended to bend their fingers. CONCLUSION: There are differences between vertical and traditional flat mice in terms of ergonomic indicators. Although more studies are needed, it seems that vertical mice are better in some indicators.

Protective gloves, hand grip strength, and dexterity tests: A comprehensive study.

Protective gloves can affect hand performance indicators (HPIs) like manual dexterity and hand grip. The present study was conducted to comprehensively and comparatively investigate several types of protective gloves and HPI assessment tools. Seventeen healthy men participated in this study. Four types of protective gloves, two structural firefighting and two general protective gloves, were investigated using four different dexterity tests and the bulb dynamometer. Structural firefighting gloves were significantly different in terms of dexterity, while there was no significant difference between general protective gloves. In contrast, firefighting gloves were not significantly different in terms of hand grip strength, while general protective gloves were significantly different in this regard. Among the four investigated tests, the hand tool dexterity test had the highest discrimination power. The negative effects of structural firefighting gloves on HPIs were higher than those of general protective gloves. A trade-off between safety requirements and hand performance is needed.

A systematic review and meta-analysis of the association between shift work and metabolic syndrome: The roles of sleep, gender, and type of shift work.

This study was conducted to investigate the association between shift work and metabolic syndrome (MetS) and quantify the roles of sleep, gender, and type of shift work. We searched online databases, including PubMed, Scopus, and Web of Science on November 17, 2019. Of the 821 articles identified, 38 observational studies (27 cross-sectional, 10 cohorts, and one nested case-control), conducted on 128,416 participants, met our eligibility criteria. The pooled Odds ratio (OR) and 95% Confidence interval (CI) of MetS in shift-versus day-workers were estimated as 1.14 (1.07, 1.21) and 1.11 (1.06, 1.17) for the unadjusted and adjusted models. This association remained significant only for the studies with a cross-sectional design. There was a significantly higher odds of MetS in the studies conducted only on females (1.13 [1.06, 1.20]) or males (1.12 [1.02, 1.21]). The pooled adjusted OR (95% CI) for the studies without and with sleep adjustment was calculated as 1.14 (1.08, 1.21) and 1.29 (1.06, 1.52). We observed that rotating shift workers had stronger odds of MetS than the other shift workers. In conclusion, our findings revealed the significant odds of an association between shift work and MetS and different effects for sleep, gender, and type of shift work.

The association between road traffic noise and myocardial infarction: A systematic review and meta-analysis.

This systematic review and meta-analysis study aimed to investigate the association between exposure to road traffic noise (RTN) and myocardial infarction (MI). Of 681 studies found by searching in databases, including Scopus, Web of Science, Embase, and PubMed on November 29, 2019, the number of 13 studies, including seven cohort, five case-control, and one cross-sectional studies with 1,626,910 participants and 45,713 cases of MI was included. The pooled relative risk (RR) and 95% confidence interval (CI) of MI were calculated using a random-effect model across studies. Heterogeneity measures by reporting the I-square index. Subgroup analysis according to the designs and sensitivity analysis based on the Jackknife approach was performed. We observed in the eight studies the association was investigated in different noise exposure groups and in the 10 studies (including two conference papers) the risk of MI was provided per specific unit increment of RTN. We ran two independent types of meta-analyses involving a categorical analysis (comparing the highest and the lowest category of noise exposure groups) and an exposure-response analysis (the risk of MI per 10-dB increment of RTN). The pooled RR (95% CI) of MI for the categorical and exposure-response meta-analyses was calculated 1.03 (0.93, 1.13) and 1.02 (1.00, 1.05), respectively. For both types of meta-analyses, subgroup analysis indicates a significant association in the studies with case-control and cross-sectional designs but not cohort studies. For the exposure-response meta-analysis, a significantly greater risk of MI was observed after excluding the two conference papers (RR = 1.03 and 95% CI = 1.00, 1.05) and by further excluding the studies provided originally the risk of MI only for the categorical analysis (RR = 1.02 and 95% CI = 1.01, 1.03). We did not show a significant publication bias across studies. In conclusion, our study suggests a significant odds of association between exposure to RTN and the risk of MI.
