Mental fatigue caused by the Covid-19 crisis and the quality of mother-child interaction are among the main challenges faced by mothers of children with attention deficit/hyperactivity disorder. so, The present study was conducted with the aim of determining the effectiveness of overexpressed emotion management training using an interactive ecological approach on mental fatigue caused by the Covid-19 crisis and the quality of mother-child interaction in mothers of children with attention deficit/hyperactivity disorder.

The present study was a semi-experimental design with pre-test-post-test type. The statistical population of this research included all the mothers of children with attention deficit/hyperactivity disorder in the treatment and rehabilitation centers of Tehran in 1400. From among the target population, 14 subjects from Arghavan Psychology and Counseling Service Center were selected as the research sample by voluntary sampling method and randomly assigned to two experimental (7 people) and control (7 people) groups. During 13 sessions of 45 minutes, the experimental group was subjected to an overexpressed emotion management training program based on an interactive ecological approach, but no intervention was done on the control group. Both groups (control and experimental) responded to the Chaldor Fatigue Scale et al (1993)  and Pianta Parent-Child Scale (1994) before and after the intervention. To analyze the data, the method of multivariate analysis of covariance was used using SPSS version 23 software.

There was a significant difference between the average post-test scores of the intervention group and the control group, so that overexpressed emotion management training reduced mental fatigue (P=0.018 and F=18.544), reduced conflict (899 F=5.038, P=0.038), increased closeness (F=5.699, P=0.041), decreased dependence (F=5.394, P=0.045) in mothers of children with attention deficit/hyperactivity disorder in The group intervened.

Considering the results obtained from this research on the effectiveness of overexpressed emotion management training using an interactive ecological approach, it is appropriate for therapists and specialists of attention deficit/hyperactivity disorder to train overexpressed emotion management using the approach Put interactive ecology in the educational priority of these mothers.

Mental fatigue usually occurs after long-term cognitive activities, reducing cognitive performance and leading to motor coordination changes. Therefore, this study aimed to investigate the effect of Swedish relaxation massage on reducing mental fatigue and enhancing knee strength and Proprioception in university female athletes. In this study, 16 female physical education athletes were randomly selected as a sample based on the inclusion criteria and subjected to the mental fatigue protocol (45 minutes of cognitive activity). Active and passive knee proprioception was evaluated with an inclinometer before and after mental fatigue, and knee extension strength was evaluated with a manual dynamometer. After 48 hours, the subjects underwent a Swedish relaxation massage. Immediately following the massage session, assessments were conducted to measure mental fatigue and the second post-test. A repeated measures analysis of variance test was employed to examine the intra-group changes over time. The findings showed a significant difference between the subjects' mean scores of active Proprioception, passive Proprioception, and knee extension strength in comparing the post-test of mental fatigue with the post-test of Swedish relaxation massage (P<0.05). The present study's findings showed that Swedish relaxation massage can be used as an effective intervention in controlling mental fatigue. Therefore, this intervention can be used to prevent sports injuries of athletes, especially amateur athletes, where mental fatigue is common.

 Nowadays, Participating in sports activities along with mental fatigue causes musculoskeletal injuries and one of the most important factors in reducing the rate of these injuries is having proper recovery. Swedish relaxation massage and meditation are some of the interventions that can possibly affect people’s mental fatigue. Therefore, the purpose of this study was immediate effect of Swedish relaxation massage and meditation after mental fatigue on dynamic and semi-dynamic balance and Lower extremity function in collegiate female athletes.

 the current study is a pre-experimental design with pre- and post-test and intervention practices in an experimental group. 16 female athletes aged 20 to 24 years at Razi University were purposefully selected as samples that they were subjected to protocols of mental fatigue (45 minutes of cognitive activity [stroop test]), Swedish relaxation massage (30 minutes) and meditation (30 minutes) with an interval of 48 hours. We were evaluated Dynamic balance with a Y-balance device, semi-dynamic balance with a Lafayette Stability Platform, Lower extremity function with left test. Data analysis was performed using SPSS software, version 22 through paired t-test. 

 There was a significant difference between the semi-dynamic, dynamic balance and lower extremity function means in pre-test to post-test, as the means decreased after fatigue (P<0.05). Also, there was a significant difference between post-tests means of semi-dynamic, dynamic balance and lower extremity function between Swedish relaxation massage and meditation (P<0.05).

 In order to prevent injury to athletes, Swedish relaxation massage and meditation can be used as interventions to reduce mental fatigue and improve balance and Lower extremity function.

Nursing is known to be a stressful job, and the psychological pressure caused by existing stressors has an adverse effect on both the individual and the organization.The purpose of this study was to examine the effectiveness of mindfulness based stress reduction (MBSR) on mental fatigue, perceived stress, and emotion regulation in nurses of Shafa hospital in Urmia.

The current research method was semi-experimental, with a pre-test-post-test design and a control group. The statistical population of the research was all the nurses of Shafai Hospital in Urmia city (200 people), among whom 30 people were selected in a targeted way and were replaced by random method in two experimental and control groups. Data collection tools included psychological fatigue scale, emotion questionnaire and perceived stress scale. The implementation method was in the order that first the subjects were selected by the screening method and divided into two separate experimental groups. And before the implementation of the intervention in each group, three questionnaires were administered as a pre-test on the participants of all groups. After that, each experimental intervention was implemented on separate experimental groups, and finally, the same questionnaires were again implemented as a post-test on the participants of both experimental groups. Data analysis was done using multivariate covariance test in SPSS22 software.

The average scores of nurses' mental fatigue before and after the intervention in the experimental group were 7.13±1.68 and 10.6±1.68 respectively and in the control group 10.8±3.61 and 2.99 respectively. It was ± 27.11. The average scores of perceived stress in the stages before and after the intervention in the experimental group were 35.6±6.42 and 29.73±3.99, respectively, and in the control group, 37.8±5.82 and 6.97±6, respectively. 36.36 and the average emotion regulation scores before and after the intervention in the experimental group were 60.53±4.36 and 65.6±7.49 respectively and in the control group 61.33±5.54 and 87.53±53 respectively. It was 60/ The results showed that the average scores of mental fatigue, perceived stress, and mindfulness in the experimental group, after the intervention of stress reduction based on mindfulness, have decreased significantly compared to the control group (p<0.01).

The results showed that stress reduction training based on mindfulness leads to improvement of perceived stress level and improvement of mental fatigue and level of emotion regulation in the group of nurses. Therefore, it is suggested to use this intervention for psychological empowerment and emotion regulation of nurses

Chronic stress can reduce cognitive functions including short-term memory. Regulating caloric intake reduces the effects of chronic stress. Fasting, which is an important feature of spiritual health, is one of the ways to control calorie intake.

Twenty volunteers (6 females and 14 males) were included in the study after the initial examination and ensuring that there was no mental or underlying illness. The passat test was taken two days before Ramadan. The variables are the variables of general mental health, reaction speed, constant attention, cognitive error, and mental fatigue. Saliva samples were taken to determine the level of cortisol and the weight of the volunteers was recorded. The same tests were performed two days after Ramadan.

Saliva concentration of all individuals at the beginning of Ramadan was lower than at the end (P<0.05). General mental health of individuals increased after Ramadan (P<0.05). Also, response time, continuous attention, cognitive error, and mental fatigue improved after Ramadan compared to before, which was statistically significant (P<0.05). The participants' weight had decreased by 1400±200 g at the end of Ramadan.

This study showed that despite the increase in cortisol concentration due to fasting, all cognitive indicators in fasting people had improved and, therefore, Islamic fasting as an important indicator of spiritual health can help improve cognitive health.

employees have a significant impact on the organization productivity and efficiency. On the other hand human performance may have effect by environmental conditions. The purpose of this research was to investigate the association between workplace environmental factors, mental fatigue, and worker performance in open plan offices.

This descriptive-analytical cross-sectional study was conducted with 85 office employees from an industrial company. Workplace physical factors such as noise, light, and temperature were assessed. Job performance (cognitive and Time) and Mental Fatigue Scale (MFS) questionnaire were evaluated.

The workers' time performance had a significant and inverse correlation with the noise level in the workplace (r=0.251). In addition, the aforementioned performance exhibited a substantial link with the temperature of the working environment (at the 0.01 level) and an inverse correlation (r=0.317). The workers' time performance was not identified (p> 0.05). The association between both cognitive performance variables and the three workplace factors of noise, light, and temperature was not statically important (p>0.05). There was a considerable correlation between mental fatigue and noise intensity (r= 0.303), but there was no correlation between the light intensity and mental fatigue among the office employees in open plan offices. (p>0.05).

The results of this research demonstrated that noise and temperature may be stressful and lead to an increase in the mental workload and mental fatigue of employees who work in open plan offices, hence impacting the work performance of them. Therefore, reducing workplace stressors (noise and temperature) and mental fatigue is essential to improve the performance of office employees.

Fatigue is a gradual and cumulative process. This mindset is related to the lack of motivation to make any effort, as well as decreased efficiency, attentiveness, and, eventually, malfunction.

The present study aims to investigate how mental and muscle fatigue affects spatial working memory.

The research method was quasi-experimental and was performed using the pretest-posttest design. The participants in this study were 20 to 30 year old male students of Shahid Beheshti University of Tehran in 2021, of whom, 14 subjects were selected by convincing method as the sample using the G-Power approach and previous investigations. The Mental Fatigue Self-Assessment Scale, Corsi Block software, Stroop software, and the Monark Bike Ergometer were utilized. In addition, the repeated measurement analysis of variance test in SPSS-23 was used to analyze the data. 

The results indicated that mental fatigue condition had a significant effect on working memory (P=0.002); and has reduced the efficiency of working memory. But muscle fatigue conditions had no significant effect on assessing working memory, and in these conditions there was a better performance in working memory (P=0.065).

The findings of this study emphasize the importance of mental fatigue in reducing working memory performance, even though this type of fatigue is related to cognitive and cerebral functioning. Accordingly, the findings are in line with a top-down approach, as well as cognitive perspectives such as generalized motor program theory.

Electroencephalography is one of the non-invasive and relatively inexpensive methods that can be used to evaluate neurophysiology and cognitive functions. This systematic review study was performed with the aim of using electroencephalography (EEG) in ergonomics.

In this review study, all articles published in Persian and English on the application of electroencephalography (EEG) in ergonomics from March 20, 2010 to March 21, 2021 were reviewed. For this purpose, a systematic search of articles was performed using the keywords cognitive ergonomics, mental fatigue, electroencephalography, EEG and brain waves in the databases of PubMed, Google Scholar, Web of science, SID, Scopus, Magiran Iran Medex.

Most studies were conducted between 2015 and 2020 (41 papers) and most of the subjects were car drivers. Selected articles were reviewed in seven areas of mental fatigue, mental workload, mental effort, visual fatigue, working memory load, emotions, stress, and error diagnosis. The journal Perceptual and Motor Skills, followed by Applied Ergonomics, published the largest number of related articles.

In the reviewed articles, the assessment of a person's mental states, especially when driving a vehicle, has been further studied and through it, tracking, monitoring and various tasks of working memory have been followed. Future research should focus on the use of computational methods that take into account the dynamic and unstable nature of EEG data. Such an approach could facilitate the development of fatigue detection systems and automated adaptive systems.

Mental fatigue usually occurs after prolonged cognitive activities that decrease cognitive function and lead to changes in motor coordination. The purpose of the present study was to investigate the effect of mental fatigue on balance, lower extremity function, and landing biomechanic changes in amateur male athletes.  

In the current quasi-experimental study, 35 amateur male students volunteered. Mental fatigue was induced by 45 minutes of cognitive activity (Stroop test). Before and after mental fatigue, the followings were evaluated: dynamic balance using Y-Test, semi-dynamic balance using Lafayette Stability Platform, knee proprioception using Inclinometer, lower extremity function using LEFT Test, landing mechanic using Balance Error Scoring System, and Jump-Landing skill film assessment using AutoCAD and Kinovea software. Data were analyzed making use of SPSS software (version 22) and running paired sample t-test at the significance level of 0.05.

The results of Paired sample t-test showed that lower extremity function (P=0.0001), dynamic balance (P=0.0001), semi-dynamic balance (P=0.0001), and knee proprioception (P=0.0001) decresed and landing biomechanics (P=0.004), which have been reported as the predictors of lower extremity injuries risks after undergoing mental fatigue, increased significantly.

According to the results, significant decrease in balance, lower extremity function factors, and increased landing mechanics of amateurs after mental fatigue have been shown, and injury prevention experts should study the strategies for the prevention of mental fatigue.

Social workers have previously been identified as being at risk of experiencing fatigue, stress and burnout. Social work is strongly client-based, with workers being involved in complex social situations. As such, they can experience many of the conflicts that are evident in human service work. In addition, the last decade has seen a transformation in the nature and practice of social work, as a result of administrative, societal, and political change. A number of writers have commented that much of what is known about stress and burnout among social workers is anecdotal and there is a lack of systematic research findings on this subject. Fatigue is generally defined as a sense of persistent tiredness or exhaustion that is often distressing to the individual. It is a common subjective complaint among formal caregivers. Accordingly, the etiology of fatigue is believed to be multifactorial. Fatigue is often described by those who experience it in terms of physical, mental, and emotional tiredness. These sensations may be sufficiently consistent as to be characterized as unidimensional or, conversely, as sufficiently distinct in their expression as to be characterized as different dimensions of fatigue. This multidimensional characterization of fatigue is evidenced by the large number and variety of multidimensional fatigue measures currently available. The psychological consequences of providing social support and care to traumatized individuals have been under study for over 2 decades; however, few studies have focused on formal caregivers (i.e., therapists, child protection workers, nurses, social workers, etc.) and their emotional response to dealing with traumatized clients. Studies have shown that providing such care can be both highly rewarding and highly stressful. Individuals working in the care-giving professions, though, may have occupational environments and caregiving demands that increase the likelihood of adverse psychological outcomes Theoretically, individuals working in the caring professions often attempt to alter the behaviors and emotions of their clients by providing emotional support (e.g., empathy), strategies for coping with emotions, or better cognitive management skills. Within the context of formal caregiving, providing therapy to clients who have survived a traumatic event can be particularly stressful. Many researchers have indicated that therapists who work with traumatized clients often show signs of psychological distress as a result of these interactions. The adverse impact of working with clients who have a history of psychological trauma (e.g., sexual and physical abuse, military combat, or community disaster) has been described under a variety of terms: vicarious traumatization, secondary traumatic stress, and fatigue.

The present study is a cross-sectional descriptive study that examines multidimensional fatigue in Iranian social workers. This study was conducted from July to November,2019. The statistical population of the study consisted of all those working in the field of social work in Iranian governmental and non-governmental organizations who were employed at the time of the study. Sampling was done by available method and snowball. A total of 334 people participated in the study. In the present study, the MFI standard questionnaire was used to measure fatigue, which is recognized as one of the most effective and most complete multidimensional fatigue measuring tools. A review of the literature and a history of applying the MFI questionnaire indicate that numerous studies have been carried out worldwide using the above-mentioned questionnaire. This questionnaire provides a deeper and more accurate understanding of a person's fatigue by assessing the extent of general fatigue, physical fatigue, reduced activity, reduced arousal, and mental fatigue. In fact, the MFI measures fatigue in the way that a person feels. General physical exhaustion is related to one's overall day-to-day functions, physical exhaustion is related to physical sensation that is directly related to exhaustion, mental exhaustion is associated with reduced cognitive skills, reduced daily activity, and reduced activity and routine activity. Reduction of motivation refers to a decrease or lack of motivation to start any activity. This questionnaire is applicable to the population of patients and healthy people and consists of 20 items rated on a 5-point Likert scale (from 1 = yes completely right to 5 = completely wrong). Ultimately, higher scores indicate a higher degree of fatigue. It is noteworthy that four questions were considered for each dimension and simultaneously positive and negative orientations were used to reduce the likelihood of bias. The total score for each dimension is 4–20 and the total fatigue score which is achieved by summing the scores of the areas is between 20 –100. This questionnaire was first presented by Smiths in 1996, and its validity and reliability in different groups of cognitive populations, such as patients with cancer who were undergoing radiotherapy, patients with concomitant fatigue syndrome, first-year psychology and medical students, soldiers, and third-year medical students were evaluated. Alpha-Cronbach's coefficient was higher than 80% for general, physical and mental fatigue and above 65% for reduced activity and excitement. Cronbach's alpha coefficient for this study was 69%. Demographic characteristics of the sample members including age, education, marital status, work experience, place of work, etc. were collected through a separate questionnaire and a sample questionnaire along with the main questionnaire. The questionnaire was prepared electronically and sent to social workers working in different fields via SMS, email, questionnaire link sharing in social worker social media groups and channels. Data was analyzed by SPSS version 22 using descriptive statistics, Mann-Whitney and Kruskal-Wallis tests.

The age of participants was 21 to 62 years with a mean and standard deviation of 38.91± 23.82. 84 (25.1%) participants were male and 250 (74.9%) were female. The mean and standard deviation of the fatigue score was 62.72± 4.9. Mental fatigue and reduced motivation with a mean of 12.8 were the highest among the dimensions of fatigue. 66.8% of participants reported too much fatigue. 32.9% had moderate fatigue and only 0.3% had no fatigue. The results of mean comparison showed that the mean score of fatigue of social workers in social services area (welfare organization, charity associations and hospitals) was higher than other areas. Age group 56-62 reported higher mean fatigue than other age groups. Social workers with more than 30 years of experience also reported greater job fatigue than others. The results of mean comparisons showed that the mean of fatigue dimensions was different in the different domains (Chi-Square = 6.806 sig = 0.047), in the different age groups (Chi-Square = 1.715 sig=0.034) and in individuals with different work experience (Chi-Square= 0.861 sig=0.035).

Due to the nature of the social work profession, employment in different workplaces creates different levels of fatigue for social workers.. Therefore, the fatigue caused by employment in this profession is inevitable, and training self-care practices and the ability to change and rotate in different areas of work for social workers can reduce the effects of job fatigue. Making sense of a career and reviewing the reasons for being a social worker are some of the things that can reduce job fatigue. Developing a personal philosophy that guides the thinking and practice of social work will also be effective.

The stress caused by parenting a child with autism leads to caregiver burden and mental fatigue in mothers. The purpose of this study was to investigate the effectiveness of mindfulness-based stress reduction of caregiver burden and mental fatigue of mothers with autistic children. 

The research method was semi-experimental with a pre-test/post-test and a control group design. The statistical population of the present study included all mothers of children with autism in autism educational centers in Isfahan in the academic year of 2018-2019. Among them, thirty mothers were selected by the available sampling method and then randomly divided into two experimental and control groups. For data collection, the mental fatigue questionnaire (Falman et al., 2013) and the caregiver burden questionnaire (Zarit et al., 1980) were used in the pre-test and post-test state. The experimental group received mindfulness-based stress reduction therapy for eight sessions, but the control group received no intervention. Data analysis was performed using covariance analysis.

The results showed that mean scores of caregiver burden and mental fatigue in the experimental group significantly decreased. (P<0.05)

Based on the findings of this study, it can be concluded that mindfulness-based stress reduction can be used as an interventional method in reducing the caregiver burden and mental fatigue of mothers with an autistic child.
