Each non-invasive neuroimaging technique has its own inherent limitations resulting from temporal and spatial inaccuracies due to the nature of information that can be measured. Recent advances in non-invasive brain imaging techniques enable us to choose a set of the most appropriate imaging modalities depending on the purpose of the study from several possible candidates. In this paper, I briefly summarize the characteristics of the major brain imaging techniques, namely, electroencephalography (EEG), magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI) and near-infrared spectroscopy (NIRS). Also, some examples of using these neuroimaging techniques to visualize brain activities related to subjective sensation of mental fatigue are presented to show potential application of the techniques for the quantitative evaluation of stress and fatigue.

Chronic stress affects decision-making, especially shifts dominant modes of decision-making from goal-directed action to habit action. Animal studies have revealed that atrophy of the prelimbic and inflalimbic prefrontal cortex and dorsomedial striatum as well as hypertrophy of the dorsolateral striatum by chronic stress mediates the alteration of decision-making. We expanded this finding to humans by a neuroimaging study and further suggested that chronic stress causes dysfunctional regulation of physiological responses by the brain. Another study using functional and structural neuroimaging replicated these findings and further showed that stress-caused alterations of decision-making and the structure and function of the brain can be reversible once individuals are released from stress. Stress-induced habit action might mediate the association between chronic stress and diseases by leading to unhealthy behaviors such as over-consumption of tobacco and alcohol, less physical activity, and addition to drugs. Further studies are needed to clarify detailed mechanisms by which chronic stress causes alterations of the brain and decision-making, and possibility of effective preventions for maladaptive influences on health.

Previous studies have reported that individuals with eating disorders (EDs) are more likely to use maladaptive emotion regulation strategies (ERS), and therefore less likely adaptive ERS than controls without EDs. However, these prior studies examined the differences in frequencies of ERS between individuals with EDs and those without EDs without controlling for depression and anxiety, which are known to be associated with symptoms of EDs and thus may influence the differences in ERS levels. Therefore, the current study investigated the differences in frequencies of using ERS (including rumination, brooding, reflection, cognitive reappraisal, and emotion suppression) between females with and without EDs, while controlling for depression and anxiety. A total of 2000 female adults (aged 20-59 years) completed a battery of online self-report measures. Analyses of covariance indicated that patients with EDs used ruminative strategies (rumination, brooding, and reflection) more frequently than females without EDs. The effect sizes of these differences were small, whereas the effect sizes regarding levels of depression and anxiety were large. In contrast, regarding cognitive reappraisal and emotion suppression, no significant differences were found between the two groups. These results suggest that higher levels of ruminative thoughts patients with EDs may not be cognitive symptoms stemming from EDs as previously understood, but instead from depressive and anxiety symptomatology.

This article gives an overview of the recently introduced concept of work engagement: a positive, fulfilling, affective motivational state of work-related well-being. I first define engagement as a state including vigor, dedication, and absorption, and then refer to how engagement differs from related concepts (i.e., burnout and workaholism). Work engagement is a unique concept that is best predicted by job resources (e.g., autonomy, supervisory coaching, performance feedback) and personal resources (e.g., optimism, self-efficacy, self-esteem) and is predictive of psychological/physical health, proactive organizational behavior, and job performance. The most often used instrument to measure engagement is the Utrecht Work Engagement Scale, a self-report instrument that has been validated in many countries across the world. The paper closes with practical implications to improve work engagement in terms of job and personal resources.

The purpose of this study was to develop a stress-related growth scale for athletes. The subjects were 627 Japanese athletes (male = 274, female = 353, mean age = 34.98, SD = 7.95). They were asked to answer a set of questionnaires including a face sheet and Stress-Related Growth Scale for Athletes (SRGSA) which was developed in this study. The result of exploratory factor analysis revealed a 3-factor solution with 15 items of the SRGSA. Each of the factors demonstrated acceptable internal consistency with Cronbach’s alpha reliability values ranging from 0.812 to 0.913. A confirmatory factor analysis indicated that the structural validity of the SRGSA showed acceptable fit indices (GFI = 0.950, AGIF = 0.927, CFI = 0.971, RMSEA = 0.057). These results suggested that the reliability and the validity of the SRGSA as a scale for assessing athletes’ stress-related growth was statistically satisfied. In future research, an investigation for athletic club members and junior athletes should be considered in order to confirm the structure of SRGSA.

The purpose of this study was to investigate the influences of attainable goal-setting on speech-related cognition in socially anxious individuals. Forty undergraduates completed 2 speech tasks, and we examined changes in speech-related cognition depending on the presence or absence of goal-setting. Participants in the goal-setting condition set attainable goals for speech tasks using worksheets by themselves, and participants in the control condition completed arithmetic tasks. Unexpectedly, in the control condition, perceived social standards in those with a high level of social anxiety were attenuated. In addition, state anxiety after speech tasks decreased in the control condition regardless of social anxiety. These findings suggest that goal-setting in the method of this study led to an increase of perceived social standards and state anxiety.

The aim of this study was developing the reason for selection of coping scale which measures the degree of selecting the coping for controlling/obtaining the positive things (the selection for accessing one's purpose) and for controlling/removing the negative things (the selection for avoiding negative things), and examined its reliability and validity. Six hundred sixty two workers, undergraduate students, and graduate students were asked to complete questionnaire. According to the results of analyses, the reason for selection of coping scale was consisted of two factors (the selection for accessing one's purpose and the selection for avoiding negative things) and its reliability and validity was confirmed. Finally, the importance of the reason for selection of coping scale and the limitation of this study were discussed.

Consistent with the concept of security priming, it was hypothesized that reminders of significant others providing sense of security would invite individuals to be tolerant of a romantic partner’s lies. Two experiments were conducted to test this hypothesis. Security priming was performed by asking participants to recall a real life experience suggesting their own significant others’ supportiveness. Dependent variables were the responses to hypothetical situations in which a romantic partner had lied and the deception had been discovered. Experiment 1 showed that security priming could reduce the degree of ungenerosity interference in forgiving a partner, after the deception had been discovered. Experiment 2 showed that this effect did not result from the mildness of threat stimuli attributed to the fact that hypothetical situations were written in third person. Taken together, these results suggested that the effect of security priming ease a self-threat produced by a romantic partner’s lies.

The 2011 earthquake and tsunami in Japan caused a meltdown at Fukushima nuclear power plant. This paper examines the association between demographics or exposure to potentially upsetting events following Fukushima disaster and psychological and physical well-being of mothers with young children 2 years after the Fukushima nuclear accident. The sample consisted of mothers with preschool children still inhabiting in low level radiation contamination area, 30~90 km distant from the plant. In addition to exposure status, the questionnaire obtained data on radiation anxiety, coping behavior, perceived economic stress and stress moderators. The dependent variables were measured by the K6, SQD (Screening Questionnaire for Disaster Mental Health).Overall, mental health of mothers with young children have been polarized as time passes. The conflict about coping behavior to radiation risk and economic stress increased the vulnerability of mothers to subsequent distress, PTSD, depression. It was confirmed a husband’s childcare participation as a stress moderator. Long-term follow-up study is needed to confirm that the progress of mental health of mothers with young children.

Interpersonal relationships are one of the most important factors that make students resilient to stressors. In the present study, we focused on social capital as an amount of available resources derived from human relationships. We examined two aspects of social capital, namely network size and subjective social capital, to determine which of the aspects is more predictive of depressive symptoms and subjective well-being. We collected data from 1,772 undergraduate students across 38 universities. Correlational analysis showed that network size was significantly associated with depressive symptoms and subjective well-being. However, the results of hierarchical multiple regression analysis indicated that subjective social capital significantly predicted depressive symptoms and subjective well-being even after controlling for network size. These findings suggest that subjective social capital in university life is an important factor for student’s psychological adjustment and well-being.

This article describes psychological support provided by clinical psychologists (CPs), in liaison with other professionals, for the Great East Japan Earthquake victims at a secondary evacuation center located in central Tokyo. The purpose of this intervention is to prevent solitary death and suicides. Nurses and CPs had organizes a team which provided consultation about health problems, psychological and social concerns. The team worked well, because of having frequent conference and consultation. So, we exchanged and shared information and pursued solutions in cooperation. In about three months of our intervention, there were 740 visits in total and 92 out of them had complaints about mental problems. Forty of them were referred to CPs' interviews. Sleeplessness and nervousness were the most common problems among them. In such cases CPs had employed 'body and mind' approach, instructing them how to relax by breathing techniques. Fortunately, no solitary deaths and suicides have been reported so far. In conclusion, it is realized that the cooperation and mutual understanding among the professionals involved are the key to the success of this type of intervention and we should know each other and enhance the sense of cooperation through the daily clinical work.

The purpose of the present study was to clarify the characteristics of behavior and problem solving related thinking among persons with high Sense of Coherence (SOC) through the methods of free description investigation and quantitative text analysis. Participants were 200 males and 200 females, (mean age = 49.0; SD = 18.3) living in different parts of Japan. They were administered a tool, wherein they provided answers to 10 questions about problem solving in daily life through free description. Additionally, they were also administered the SOC scale and Kessler 10. First, participants were classified into the high SOC group and low SOC group based on their score on the SOC scale and Kessler 10. Following this, the answers of free description were analyzed by co-occurrence network analysis. The results of this analysis indicated that persons with high SOC were more likely to adopt positive and strategic behaviors and thoughts for solutions after objectively understanding the problem at hand. Moreover, it was found that the characteristics of persons with high SOC persons not only reflected in the personal areas of their life such as problem solving, dealing with stressors, and emotions but also in interpersonal areas such as communication and interpersonal relationships.

The purposes of the present study were to report a loneliness reduction model using student’s subjective social capital (SSC), computer mediated communication (CMC) or face to face (FTF) behavior and perceptions of the closed spaces, crowded places, close-contacts avoidance (perceptions of the norms of avoiding 3Cs) in COVID-19 pandemic. In this article, we focused on subjective social capital as people’s cognition of the psychosocial resource availability accumulated by contact with others. Online cross-section research was conducted at 3th faculties in a Japanese private university, in July 2020, collecting 732 samples. And analyses were done for 659 samples. The results showed that the norms of avoiding 3Cs affected computer mediated or face to face communication behavior, and computer mediated or face to face communication behavior affected SSC, and the SSC reduces loneliness. These results imply that SSC, CMC and FTF are the important factor for student to decrease loneliness in COVID-19 pandemic.

This study examined the effects of interaction with others in vacation on subjective happiness and depression. Employees have been experiencing substantial changes in working conditions, and such changes cause an increase of stress. In such a background, the number of people with mental health disorder is rising, and it becomes a major problem in these days. Previous studies have indicated that vacation greatly influences on individual subjective happiness and stress state. However, the number and area of participants in previous studies were limited. Therefore, we conducted an Internet survey and collected participants of various ages from different areas in Japan. The total of 275 adults (109 women, 166 men) participated in this study. As a result of the analysis, the interaction with others in vacation was positively associated with subjective happiness, whereas subjective happiness was negatively associated with depression symptoms as a reaction to stress. These results suggest that reconsidering about vacation have a possibility to promote individuals’ mental health.

Maltreated children have experienced many traumatic events, unstable familial environments, or separation and/or loss in their family. Most of maltreated children have problems in emotional development as well as difficulties in cognitive development or trauma related psychopathology. For example, some of them have attachment disorder, dissociative disorders, or problems in personality development. Moreover, some of them may have attention deficit disorder, mental retardation, or autism spectrum disorder. Most of them have strong desire for secure relationships with reliable and protective adult persons. On the other hand, most of them also have feelings of mistrust toward adult persons generally. They tend to have ambivalent feeling toward adult caretakers and complicated psychopathology. Care workers, social workers, teachers, and mental health professionals involved in these children should understand their complex psychopathology and strong need for psychological cares. In psychological cares, many of maltreated children are thought to need multidimensional and multidisciplinary interventions including secure environments, longtime foster care, individual psychotherapy, special education as well as psychiatric care.
